- Abstract/Description
-
The levels of 3 dimensions of sexism and 13 measures of psychosocial adjustment were assessed in 236 children in grades 4 through 8. The adjustment measures were factor analyzed to produce 5 adjustment factors. Analysis revealed that one of the factors, peer-reported prosocial tendencies, was moderately and negatively correlated with two of three measures of sexism. This effect was more pronounced for girls than for boys. Another factor, body self-esteem, was negatively correlated with one of...
Show moreThe levels of 3 dimensions of sexism and 13 measures of psychosocial adjustment were assessed in 236 children in grades 4 through 8. The adjustment measures were factor analyzed to produce 5 adjustment factors. Analysis revealed that one of the factors, peer-reported prosocial tendencies, was moderately and negatively correlated with two of three measures of sexism. This effect was more pronounced for girls than for boys. Another factor, body self-esteem, was negatively correlated with one of the measures of sexism for girls. The findings are congruent with the view that traditionally sexist ideology may detrimentally impact children's psychosocial adjustment.

Show moreThis experiment investigated an individual's memory of specific motion events, unique actor, intrinsic motion, and extrinsic motion combination. Intrinsic motions involve the movement of an individual's body parts in a specific manner to move around, while extrinsic motions specify a path in reference to an external object. Participants viewed video clips, each depicting an actor performing a unique extrinsic and intrinsic motion combination. One week later, they viewed a different series of retrieval video clips consisting of old (identical to encoding), extrinsic conjunction (extrinsic motion previously performed by different actor), intrinsic conjunction (intrinsic motion previously performed by different actor), and new (novel extrinsic or intrinsic motion) video clips. Participants responded "yes" to viewing the old video clips the most often, followed by conjunction video clips, and then new video clips. Furthermore, there were a greater number of "yes" event memory recognition responses for extrinsic conjunction items than intrinsic conjunction items.

Show moreCancer is the second leading cause of death in the western world. In order to treat various types of cancer, platinum-based drugs are most widely employed as metal-containing chemotherapeutic agents. However, their clinical usage is hindered by toxic side effects, and by the emergence of drug resistance. Our focus was to replace platinum with less toxic metal like tin which can give better alternatives for cancer treatment. The major aim of our study was to synthesize novel organotin polyethers (Sn-O) which can be used to combat cancer. Preliminary results from our laboratory using organotin polyethers, that were synthesized by varying the structure of diols showed growth inhibition in Balb-3T3 cells. This study directly led us to hypothesize the two structural windows, first by changing the distance between diol and second, by presence of unsaturation in diols, the biological activity of organotin polyethers (Sn-O) can be enhanced significantly. Different series of polymeric compounds were synthesized based upon these two structural windows and the formation of products was validated using standard techniques like infrared spectroscopy (IR), light scattering photometer, matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) and nuclear magnetic resonance (NMR). The synthesized polymers arrested the growth of cancer cell lines including bone, prostate, colon, breast, pancreas and lung cancer derived cell lines in vitro. In number of instances where chemotherapeutic index values of two and greater were found that these polymers are significantly more active against cancer cells than non-cancerous cells in culture., These results support the starting premise that the polymers may exhibit cancer cell selectivity. In general, it was found that the presence of unsaturation increased the probability that the polyether would inhibit the growth of various cancer cell lines. Further, in some cases, polyethers with short distances between the oxygen atoms showed a superior ability to inhibit the growth of various cancer cell lines in comparison to those with longer distances between the oxygen atoms. These results provide a framework for the discovery of novel cancer therapeutics.

Show moreThis thesis explores radicalism at work in M. Maxwell Philip's Emmanuel Appadocca (1854) and China Miâeville's The Scar (2002). These novels highlight piracy as a means of rejecting systems of power and social order. Through speculative fiction, each author finds the means to resist the hegemonic power of genre, race, empire, and knowledge that pervade each author's social and historical milieu. This work examines the historical and literary context of piracy as a metaphor for radicalism, the project of legitimization and resistance to generic categorization of both texts. Emmanuel Appadocca resists racial stereotypes, and both texts exhibit clear resistance to colonial expansion. This resistance is made possible by each author's use of the sea as the site of insurgency and challenging boundaries of knowledge. Thus both novels lend themselves to interpretation as works of postcolonial fiction.

Show moreThe translation of Geny Vilas-Novas' novel Adeus, Rio Doce emphasizes the importance of promoting a literary exchange between Brazil and the Spanish-speaking world. This study analyses contemporary Brazilian literature and situates the author in the post-modern literary movement, stressing two post-colonial fundamental themes: emigration and feminine literature. Millions of undocumented emigrants from Latin America live nowadays in the United States displaced in the American society and leave suffering family members abandoned in their native countries. One of the roles of Latin- American women writers like Vilas-Novas is to reveal and denounce the subaltern conditions of this emigration movement in the globalization process, under the unusual perspective of those left behind. The linguistic and semantic challenges and difficulties faced during translation are a metaphor for the crossing of linguistic, cultural, social, and historical borders by Latin-Americans in search of better life opportunities.

- Abstract/Description
-
Tumor cells interact with basement membrane collagen at the site of extravasation through distinct cellular receptors, including the α2β1 and α3β1integrins. These receptors are known to be differentially expressed in metastatic tumors, relative to the normal cells, depending on tumor type and stage of progression. The binding sites within type IV collagen for the α2β1 andα3β1 integrins have been identified. Since both of the integinspecific sequences possess at least one glycosylated Hyl...
Show moreTumor cells interact with basement membrane collagen at the site of extravasation through distinct cellular receptors, including the α2β1 and α3β1integrins. These receptors are known to be differentially expressed in metastatic tumors, relative to the normal cells, depending on tumor type and stage of progression. The binding sites within type IV collagen for the α2β1 andα3β1 integrins have been identified. Since both of the integinspecific sequences possess at least one glycosylated Hyl residue, we questioned whether glycosylation could modulate integrin binding. Triple-helical peptides with and without Lys substituted by glycosylated Hyl for Lys543 and Lys540 from the human a1(IV)531-543 gene sequence (α3β integrin-specific) and Lys393 from the human a1(IV)382-393 gene sequence (α2β1 integrin-specific) were synthesized and utilized in the present study., Cellular response to these triple helical ligands was tested with a primary melanoma cell line, WM-115, and three highly metastatic melanoma cell lines , WM-266-4, M14#5, and SK-MEL-2. Cell adhesion and cell spreading assays yielded differing results depending on whether the ligands contained glycosylated Hyl residues or not. In general, a decrease in cellular affinity toward the ligands was observed when glycosylated Hyl was present. Differences in the levels of adhesion and spreading between cell lines representing different stages of melanoma were also observed. Neutral B-galactosidase activity was detected in all four cell lines. Enzymatic activity levels were comparable for the three metastatic cell lines, whereas distinctively higher activity was detected for cells originating from a primary lesion. This acitivity can signal the potential of tumor cells to enhance and recover their invasive abilities., The ability of each cell line to remove the galactose from the peptide ligands has been investigated, to test whether tumor cells can reestablish binding relationships between the α2β1 and α3β1 integrins and type IV collagen that are reduced by glycosylation.

Show moreStable and metastable phases of Fe and Al and structural anomalies of Zn and Cd have been studied by epitaxial Bain path (EBP) and minimum path (MNP) first-principles procedures, based on finding equilibrium structures from minimizing the Gibbs free energy G with respect to structure at a given hydrostatic pressure p and temperature T . The main accomplishments are as follows. (1) This dissertation illustrates the effectiveness of the MNP procedure for finding stable and metastable phases of an element by studying four Bravais phases of Fe including body-centered tetragonal (bct), body-centered cubic (bcc), face-centered cubic (fcc) and rhombohedral (rh) phases. The determination of absolute stability using MNP is new; MNP finds all the elastic constants cjj of a given state and the eigenvalues of the elastic constants matrix, which determine the absolute stability of the state., (2) We have extended our search for stable and metastable phases from zero temperature to finite temperature, which requires the calculations of the Debye temperature Od from cjj in the case of no symmetry. The Debye theory is modified by introducing a parameter B2 that gives the fraction of the full Debye zero-point energy possessed by the actual dispersive mode frequencies. The value of the lattice parameter of fcc Al at low temperatures,a(T) , is shown to be accurately determined by the modified Debye theory of lattice vibrations and first-principles total energy band calculations with the MNP procedure. (3) The existence of structural anomalies in hcp Zn and Cd has been shown from first-principles total-energy calculations using WIEN2k with the EBP procedure., Evaluation of the pressure dependence of various elastic quantities which are much more sensitive to the anomaly shows that the anomalies in hcp Zn and hcp Cd exist over a considerable range of pressure; several abrupt changes in the electron distribution are thereby indicated in that pressure range. (4) Calculations on the zone-center transverse optical phonon frequencies Vto(p) of hcp Zn, which found oscillatory behavior of Vto(p) in the pressure range of the anomalies, support the conclusions made in (3) on the structural anomalies. Based on this dissertation research four papers have been published in refereed journals.

Show moreWireless sensor networks are used in areas that are inaccessible, inhospitable or for continuous monitoring. The main use of such networks is for event detection. Event detection is used to monitor a particular environment for an event such as fire or flooding. Composite event detection is used to break down the detection of the event into the specific conditions that need to be present for the event to occur. Using this method, each sensor node does not need to carry every sensing component necessary to detect the event. Since energy efficiency is important the sensor nodes need to be scheduled so that they consume [sic] consume as little energy as possible to extend the network lifetime. In this thesis, a solution to the sensor Scheduling for Composite Event Detection (SCED) problem will be presented as a way to improve the network lifetime when using composite event detection.

Lesbian culture, today, sometimes puts pressure on the term butch and pushes butch women to choose between transgender, femme and androgynous. The lead character in this novel, Sarah, struggles to come to terms with her own sexual identity amidst all this pressure to conform. She watches her friends and searches for a model of what butch is and is not but she continues to feel emotionally and physically cut off from the people she cares about. Ultimately, Sarah realizes she can move fluidly between many genders. When she stops trying to be a stereotype, she is finally able to connect with the people she cares about.

Show moreThe objective of this study was to describe the lived experience of caring for persons who had a peaceful death in the intensive care units in Thailand. A qualitative research design informed by hermeneutic phenomenology was used to analyze data. Participants were 10 intensive care nurses working at adult intensive care units in south Thailand. A snowball purposive sampling method was used to select the participants. Participant inclusion criteria were at least six months' critical care nursing experience, experience in caring for a person who had peaceful death, able to describe peaceful death, and willing to participate in this study. Participants who met the inclusion criteria were interviewed. Face-to-face individual verbal interviews were conducted in the Thai language. These interviews were audiotape recorded. Descriptions were transcribed and translated for data analysis. Van Manen's (1990) hermeneutic phenomenological approach was used to analyze and interpret the data. The findings of this study were presented in each of 4 categories of the lived world of temporality, of spatiality, of corporeality, and of relationality. The description of the lived experience of caring for persons who had a peaceful death in ICU was, "understanding the other through the valuing of experience and enhancing relations with others by recognizing time is short and is a priority." This study may contribute to nursing knowledge of the end-of-life care to enhance a peaceful death in intensive care units congruently with Thai culture and society. In addition, this study directs the translations of its knowledge into implications that will benefit in helping Thai nursing to move forward. The implications of this study in advance will benefit terminally ill persons and family members regarding receiving good quality end-of-life care.

Show moreMicroarray expression data which contains the expression levels of a large number of simultaneously observed genes have been used in many scientific research and clinical studies. Due to its high dimensionalities, selecting a small number of genes has shown to be beneficial for many tasks such as building prediction models from the microarray expression data or gene regulatory network discovery. Traditional gene selection methods, however, fail to take the class distribution into the selection process. In biomedical science, it is very common to have microarray expression data which is severely biased with one class of examples (e.g., diseased samples) significantly less than other classes (e.g., normal samples). These sample sets with biased distributions require special attention from researchers for identification of genes responsible for a particular disease. In this thesis, we propose three filtering techniques, Higher Weight ReliefF, ReliefF with Differential Minority Repeat and ReliefF with Balanced Minority Repeat to identify genes responsible for fatal diseases from biased microarray expression data. Our solutions are evaluated on five well-known microarray datasets, Colon, Central Nervous System, DLBCL Tumor, Lymphoma and ECML Pancreas. Experimental comparisons with the traditional ReliefF filtering method demonstrate the effectiveness of the proposed methods in selecting informative genes from microarray expression data with biased sample distributions.

Show moreThis study examined organizational member and housing staff perceptions of organizational culture and effectiveness of residence hall associations. Two instruments, the Residence Hall Government (RHA) Effectiveness Instrument designed by Tucker (2001) and the Organizational Culture Assessment Instrument (OCAI) designed by Cameron and Quinn (1999, 2006) were utilized to gather quantitative data, while individual interviews and focus groups were conducted utilizing selected questions from the Interview Questions for Doing a Competing Values Organizational Analysis (Quinn 1988) to collect qualitative data. A mixed methodology was utilized to collect and analyze data from three sites yielding 217 assessments, 27 interviews, and 6 student focus groups with members of residence hall associations during the spring 2008 semester. The study indicated that there is a positive relationship between all ideal culture type scores identified by the OCAI and effectiveness constructs identified by the RHA Effectiveness Instrument. Additionally, there is a difference in the perceptions of Clan and Hierarchy ideal culture type scores and Housing Relationship and RHA Effects effectiveness construct scores based upon housing staff membership or RHA Legislative Body membership. Furthermore, the research indicated that level of student involvement, emphasis on leadership development and training, patterns of communication and teamwork, financial resources, implementation of rules and procedures, roles in program planning, student voice, member evaluation, collaborative partnerships with host housing departments, and relationships with university Student Government were constructs for the development of organizational culture and influenced the organizational effectiveness of RHAs. Recommendations are provided for the organizational development and evaluation of residence hall associations.

Show moreDisney commands a strong market presence worldwide in print and multimedia products used for early childhood entertainment. Yet, the gender and cultural bias found in Disney animated fairy tale media has been well documented. Although preprimary early childhood teachers are urged to maintain a multicultural environment that is free of bias and stereotypes, very little training or support is presented to guide preprimary early childhood teachers in the selection of materials for use in their preprimary early childhood classrooms. The study sought to investigate the influence of a professional development module focused on the gender and cultural bias found in Disney animated fairy tale media on preprimary early childhood teachers. How would they respond to this professional development module? Would it change their intentions to use Disney animated fairy tale media with preprimary early childhood children? Would the participation in this preprimary early childhood professional development module actually change their practice? Using both quantitative and qualitative inquiries, participating preprimary early education teachers reported mixed findings. While some preprimary early childhood teachers were clearly influenced by their discovery of the existence of bias in this media, others revealed a cognitive dissonance from a strong personal and emotional attachment to Disney animated fairy tale media products juxtaposed against the evidence of cultural and gender bias found in the media. Implications and suggestions for future research included the expansion of professional development modules and higher education/teacher education to include the study and consideration of the content of children's media., Policymakers and advocates need to address concerns of bias found in children's media with respect to gender and cultural bias development during the preoperative developmental stage of preprimary children. Further, interdisciplinary discussion needs to the concern of the influence of media on the holistic development of young children.

Show moreThe goal of a speech enhancement algorithm is to remove noise and recover the original signal with as little distortion and residual noise as possible. Most successful real-time algorithms thereof have done in the frequency domain where the frequency amplitude of clean speech is estimated per short-time frame of the noisy signal. The state of-the-art short-time spectral amplitude estimator algorithms estimate the clean spectral amplitude in terms of the power spectral density (PSD) function of the noisy signal. The PSD has to be computed from a large ensemble of signal realizations. However, in practice, it may only be estimated from a finite-length sample of a single realization of the signal. Estimation errors introduced by these limitations deviate the solution from the optimal. Various spectral estimation techniques, many with added spectral smoothing, have been investigated for decades to reduce the estimation errors. These algorithms do not address significantly issue on quality of speech as perceived by a human. This dissertation presents analysis and techniques that offer spectral refinements toward speech enhancement. We present an analytical framework of the effect of spectral estimate variance on the performance of speech enhancement. We use the variance quality factor (VQF) as a quantitative measure of estimated spectra. We show that reducing the spectral estimator VQF reduces significantly the VQF of the enhanced speech. The Autoregressive Multitaper (ARMT) spectral estimate is proposed as a low VQF spectral estimator for use in speech enhancement algorithms. An innovative method of incorporating a speech production model using multiband excitation is also presented as a technique to emphasize the harmonic components of the glottal speech input., The preconditioning of the noisy estimates by exploiting other avenues of information, such as pitch estimation and the speech production model, effectively increases the localized narrow-band signal-to noise ratio (SNR) of the noisy signal, which is subsequently denoised by the amplitude gain. Combined with voicing structure enhancement, the ARMT spectral estimate delivers enhanced speech with sound clarity desirable to human listeners. The resulting improvements in enhanced speech are observed to be significant with both Objective and Subjective measurement.

Show moreThe purpose of this qualitative narrative research study was to interpret the meaning found throughout the formal educational experience stories of Native American, Asian American, and African American women born after 1944, who had earned an education doctorate degree after 1976, and were working with adults in an educational capacity within the community. Utilizing the snowball technique, 14 participants from across the United States volunteered to collaborate with the researcher. The study's conceptual framework included adult learning principles and practices, Nussbaum's 'narrative imagination,' which were used to examine the women's motivation to participate in an education doctorate program as well as the barriers, the enhancers, and the application of the degree in the community. Data collected included an in-depth, face-to-face interview, two reflective narrative guides, document analysis, and researcher journals and analytic memos. All data was coded and analyzed with Atlas -ti 5.0 software, and thematic analyses completed in order to triangulate the data. Six major themes for motivation to participate were found: self-awareness through placement in the family, family and community expectation in importance of education, personal strengths and weaknesses, perceived differences in the classroom and mainstream society, and knowledge of motivation to pursue doctorate. Five barriers emerged: racism, gender, advisers, institutional changes and problems, and juggling multiple roles in limited time. Five main enhancers arose: family and community foundation, financial, friends, and others which motivated participation., The women applied their doctorates through leadership activities in community-based organizations such as role modeling, mentoring, and other scholarly activities which advocated "giving back culturally," which was the ultimate meaning or value of the degree; however, achievement and credibility were also valued a doctorate degree was "only step in the process." This study provided a space for rich descriptive storytelling about each woman's successful experience pursing and completing an education doctorate program. Adult learning discussion of the findings, contributions to the literature, and recommendations for graduate education and future research were included.

Show moreBoth Calixthe Beyala's Le petit prince de Belleville, published in France in 1992, and Cynthia Shearer's The Celestial Jukebox, published in the United States in 2005, explore similar questions regarding the place of immigrants in increasingly multicultural societies. Gilles Deleuze and Fâelix Guattari's concept of - smoothness and - striation illuminates the settings of these two texts, helping demonstrate that the Parisian neighborhood of Belleville presents a striated space dominated by State constraints, from which the residents yearn to break free, and the fictional town of Madagascar, Mississippi consists of relatively smooth space that allows for local improvisation and engenders insecurity. The stories of Loukoum and Boubacar illustrate how these two characters negotiate their respective spaces, with Loukoum creating a position thoroughly between striated majority French culture and the smoothness of his diasporic sphere and Boubacar functioning as a rhizomatic nomad, embarking on an autonomous journey of discovery.

Differences between the directors' perceived leadership style and faculties' perception of the directors' leadership style were also examined. Directors' leadership styles were measured by the Multifactor Leadership Questionnaire (MLQ). Director, faculty and program information was measured with a researcher-designed questionnaire. CoARC accredited program directors (n=321) and their full and part-time faculty (n=172) received an e-mail and a web link to obtain demographic information. All participants received an e-mail from Mind Garden, Inc. with a web link to complete the MLQ. Regression analysis and t tests were used to analyze the data. The results found a significant relationship between faculty satisfaction, extra effort, and perceived director effectiveness and each of the predictors transformational, transactional, and passive/avoidant leadership behaviors. There was no relationship between program director leadership style and program outcomes. This study found no difference between the directors' and the faculty's perception of the directors' transformational and transactional leadership behaviors. However, there was a significant difference between the directors' and the faculties' perception of the directors' passive/avoidant behavior.

Show moreThis study explored the types and uses of informal, on-the-job learning occurring among American Speech-Language-Hearing (ASHA)-certified Speech-Language Pathologists (SLPs) working in medical settings as part of a rehabilitation team. In addressing this purpose, a qualitative, phenomenological approach to research methodology was used. Participants were selected through a process of purposeful sampling, each meeting the criteria of having earned the Certificate of Clinical Competence in Speech-Language Pathology from ASHA and working in a medical setting as part of a rehabilitation team. Twenty-four SLPs from varying demographic profiles took part in one of three online data collection methods. Nine participants completed a computer-mediated interview, 11 participants completed an online journal entry and 4 participants completed a virtual focus group method. All data collection methods were accomplished via internet technologies. Data analysis was performed through a process of thematic analysis and resulted in four significant findings. First, both internal and external forces triggered SLPs to learn informally in the medical workplace. Also, SLPs went through an individually-determined, goal-directed process when learning informally in the medical workplace. SLPs used a combination of collaboration, workplace experience and research to learn informally in the medical workplace. And finally, SLPs employed informal learning activities for the purpose of meeting personal, patient and organizational needs., It was recommended that (a) the American Speech- Language-Hearing Association review its professional development policy and consider implementation of a process whereby clinicians can document their goal-directed workplace learning and receive professional development credit for these activities; (b) healthcare organizations recognize, support and reward the informal learning in which their SLPs are already engaging; and (c) SLPs enhance their informal learning in the medical workplace through proactivity, critical reflectivity (of their own and others' learning), and creativity. The significance of this research included the use and support of existing theory in both Adult Education and Human Resource Development. Further, this research represents the first of its kind in investigating informal learning in rehabilitative therapies, specifically Speech-Language Pathology. Peer professions such as Physical and Occupational Therapy may also benefit from this study's conclusions and recommendations, as these professionals work in similar medical contexts.

Show moreThe thesis proposed for my M.F.A. in creative writing is a collection of conceptual American short stories written in a variety of forms that properly suit their respective subjects. Like a handful of miscellaneous wild seeds scattered over a tilled garden, the goal of the project is to represent the wild asymmetry of Nature via a collection of unlikely companions. For this reason, the conceptual form of each story often takes root in scientific or symbolic representations of Nature (i.e. sine and cosine curves, the yin-yang, etc.). The plot of loose soil holding these collective experiments together is their earthy thematic focus-namely, the way in which Nature has been systematically backgrounded by western ideology. On occasion, a story's conceptual focus may stray from these ecofeminist principles, but only for the purpose of leveling a more critical or satirical eye upon common American ideologies.

RNA damage occurring under oxidative stress has been shown to cause RNA dysfunction and must be detrimental to cells and organisms. We propose that damaged RNA can be removed by specific RNA surveillance activities. In this work, we investigated the role of polynucleotide phosphorylase (PNPase), a 3'->5' exoribonuclease, in protecting the cells against oxidative stress and eliminating oxidatively-damaged RNA.

Show moreRNA damage occurring under oxidative stress has been shown to cause RNA dysfunction and must be detrimental to cells and organisms. We propose that damaged RNA can be removed by specific RNA surveillance activities. In this work, we investigated the role of polynucleotide phosphorylase (PNPase), a 3'->5' exoribonuclease, in protecting the cells against oxidative stress and eliminating oxidatively-damaged RNA. Previously, it was reported that E. coli PNPase has a higher affinity to poly(8-oxoG:A). We further confirmed that E. coli PNPase can specifically bind to an oxidized RNA with a high affinity. An E. coli strain deficient in PNPase (pnp) is hypersensitive to hydrogen peroxide (H2O2). Importantly, the level of H2O2-induced RNA damage, measured by the content of 8-hydroxyguanosine, increases significantly in the pnp mutant cells. Consistent with the notion that PNPase plays a direct role in these processes, introduction of the pnp gene encoding E. coli PNPase can restore the viability and RNA oxidation level of the pnp mutant cells in response to H2O2 treatment. Interestingly, degradosome-association is not required for PNPase to protect cell against oxidative stress. PNPase is evolutionary conserved in most of organisms of all domains of life. The human polynucleotide phosphorylase (hPNPase) localizes mainly in mitochondria and plays pleiotropic roles in cell differentiation and has been previously shown to bind 8- oxoG-RNA with a high affinity. Here we show that similar to E. coli PNPase, hPNPase plays an indispensable role in protecting HeLa cells against oxidative stress. The viability in HeLa cell and 8-oxoG levels in RNA are inversely correlated in response to H2O2- treatment. After removal of oxidative challenge, the elevated level of 8-oxoG in RNA decreases, suggesting the existence of surveillance mechanism(s) for cleaning up oxidized RNA., We have shown that hPNPase may be responsible for the surveillance of oxidized RNA in mammalian cells.Overexpresion of hPNPase reduces RNA oxidation and increases HeLa cell viability against H2O2 insult. Conversely, hPNPase knockdown decreases the viability and increases 8-oxoG level in HeLa cells exposed to H2O2. Taken together, our results suggest that RNA oxidation is a challenging problem for living organisms, and PNPase may play an important role in protecting both prokaryotic and eukaryotic cells by limiting damage to RNA under oxidative stress.
