Title: Unlocking the Phytotherapeutic Synergism between Beta-lapachone and Soybean-derived Genistein in Human Prostate cancer cells.
Creator: Oseni, Saheed Oluwasina, Sandoval-Bernal, Bibiana, Kumi-Diaka, James, Graduate College
Abstract/Description: Prostate cancer after many years is still the second most common cancer in American men with about 233,000 new cases and 29,480 deaths estimated to be occurring in 2014. Despite the wide spectra of reports demonstrating the anti-cancer phytotherapeutic potentials of beta-lapachone and soybean-derived genistein in various tumors, little emphasis had been placed on their synergistic effects in androgen-independent PC3 and androgen-dependent LNCaP prostate cancer cell lines. In this study, we...
Show moreProstate cancer after many years is still the second most common cancer in American men with about 233,000 new cases and 29,480 deaths estimated to be occurring in 2014. Despite the wide spectra of reports demonstrating the anti-cancer phytotherapeutic potentials of beta-lapachone and soybean-derived genistein in various tumors, little emphasis had been placed on their synergistic effects in androgen-independent PC3 and androgen-dependent LNCaP prostate cancer cell lines. In this study, we aim to characterize the combined effects of genistein and b-lapachone on the phyto/chemosensitivity of LNCaP and PC3 human prostate cancer cells in-vitro, using MTT assay and LDH assay to study treatment-induced growth inhibition and cytotoxicity. Annexin-V-FITC and PI-TUNEL assays were also used to determine the potential treatment-induced apoptosis and/or necrosis. Our results revealed that both PC3 and LNCaP are phytosensitive to both single and combined treatments, though time-and dose-dependent. We observed that our treatments induced dual death pathways-apoptosis and necrosis-in both cell types and also observed that growth inhibition in both correlated positively with cell death in which, b-lapachone and genistein induced cell cycle arrest at the G1 and/or S phase and G2–M checkpoints respectively. Invariably, our results indicate that combination treatments with b-lapachone and genistein are more potent in killing both PC3 and LNCaP cancer cells than treatment with either genistein or b-lapachone alone. Our current results are therefore in agreement with the hypothesis that drugcombinations that target cell cycles at different critical checkpoints are more effective in causing cell death.

Show moreFor highly migratory species, it is important to understand what habitats are used and what requirements are essential for growth and development. These migrations often span different political and regulatory boundaries, complicating conservation strategies. The hatchlings and post-hatchlings of most sea turtle species migrate to oceanic habitats where they remain for several years before returning to shallow developmental habitats. For critically endangered hawksbill turtle, Eretmochelys imbricata, most research has concentrated on nesting ecology and very little is known about the posthatchling migration. Many sea turtles then spend years in different foraging habitats before reaching sexual maturity, and such foraging grounds typically represent a mixed stock of turtles from different nesting beaches. Mitochondrial DNA analysis can be used to estimate genetic stock structure of mixedstock foraging populations for sea turtles, and the duration of the post-hatchling oceanic stage can be estimated using stable isotope analysis and satellite telemetry. Our objectives are to determine the duration of the post-hatchling oceanic stage of development, to determine if the turtles sampled in a particular foraging habitat represent a biased or unbiased assortment of matrilineages, and to infer potential migratory pathways by investigating ocean currents between nesting beaches and the foraging site. Here we discuss our methods, to determine the duration of the post-hatchling oceanic stage and stock structure for immature hawksbills at a developmental foraging ground.

Title: Using an immunohistochemical approach to identify the sex of marine turtles.
Creator: Tezak, Boris, Wyneken, Jeanette, Graduate College
Abstract/Description: Marine turtles exhibit temperature-dependent sex determination (TSD). During critical periods of embryonic development, the nest’s thermal environment directs whether an embryo will develop as a male or a female. At warmer sand temperatures the nest tends to produce female-biased sex ratios. The rapid increase of global temperature highlights the need for a clear assessment of effects on sea turtle sex ratios.

Show moreMarine turtles exhibit temperature-dependent sex determination (TSD). During critical periods of embryonic development, the nest’s thermal environment directs whether an embryo will develop as a male or a female. At warmer sand temperatures the nest tends to produce female-biased sex ratios. The rapid increase of global temperature highlights the need for a clear assessment of effects on sea turtle sex ratios. However, identifying hatchling sex ratios at rookeries remain coarse estimates due to the lack of any external gender markers. We rely mainly upon laparoscopic procedures to verify a hatchling sex; however, in some species, morphological sex can be ambiguous even at the histological level. Recent studies using immunohistochemical techniques identified that red-eared slider (Trachemys scripta) embryos over-expressed a particular cold-induced RNA binding protein in the ovaries in comparison to the testes. This principle allows the distinction between females and males. We developed a variation of this technique and successfully identified the sexes of loggerhead sea turtle (Caretta caretta) hatchlings, as confirmed by standard histological and laparoscopic methods that reliably identifies the sex in this species. Next, we tested a more challenging species, the leatherback turtle (Dermochelys coriacea), which retains many neotenic features. The morphology of leatherback hatchling gonads remains difficult to interpret, particularly when dead-in-nest hatchlings and embryos are the source tissues. In summary, this new and more efficient technique enhances our ability to investigate and identify baseline hatchling sex ratios, a critical progression in assessing global climate change on sea turtle populations.

Title: Utilizing Hyperspectral Reflectance to Analyze Sand Composition.
Creator: Smith, Molly E., Selch, Donna, Graduate College
Abstract/Description: Spectral signatures quickly aid the analysis of sand composition because specific wavelengths correspond with distinct minerals. This provides objectivity to traditional microscopic methods, with the option to create a custom spectral library for Hyperspectral Remote Sensing HRS applications. Removal of salt as a precipitated solid from sea water is useful for clearer microscopic viewing of sand because certain grains are less likely to be misidentified as crystalized salt.

Show moreSpectral signatures quickly aid the analysis of sand composition because specific wavelengths correspond with distinct minerals. This provides objectivity to traditional microscopic methods, with the option to create a custom spectral library for Hyperspectral Remote Sensing HRS applications. Removal of salt as a precipitated solid from sea water is useful for clearer microscopic viewing of sand because certain grains are less likely to be misidentified as crystalized salt. Though removal of salts aids in qualitative visual identification, it is problematic for studies requiring spectral reflectance data to match real-life conditions. Spectroradiometric techniques were used to assess the effects of salt in spectral signatures of sand. Sand samples of mixed siliciclastic-carbonate composition were collected from 15 locations across the southeastern Florida coast. Spectral plots were generated from laboratory collected data with an ASD Spectroradiometer. Spectral data was collected before and after samples were prepared for microscopic study. Laboratory-prepared samples show negative slope at approximately 1500 nm and 2000 nm ranges on the generated plots. These wavelengths are indicative of grains having either predominately carbonate or siliciclastic compositions, which agrees with the microscopic analysis. Salts present in a sample affect the spectral signature, thus salt removal yields spectral plots not necessarily concurrent with plots generated from raw, unprepared samples. For studies utilizing airborne HRS data, the order of data collection and preparation is important. To ensure a more precise match between the spectral library and the hyperspectral imagery, spectral data must be collected before the sample is prepared for microscopic analysis.

Title: What Controls The Nocturnal Emergence Rhythm Of Hatchling Marine Turtles?.
Creator: Prio, Joseph D., Salmon, Michael, Graduate College
Abstract/Description: Most marine organisms partition particular activities, such as growth, migration, reproduction, and hatching, to particular seasons, times of the day or night, or phases of the lunar cycle. The result is characterized as a “rhythm”. Scientists who study these rhythms generally ask two kinds of questions: why do they occur when they do that is, what is their survival value, and how are they controlled, physiologically?

Show moreMost marine organisms partition particular activities, such as growth, migration, reproduction, and hatching, to particular seasons, times of the day or night, or phases of the lunar cycle. The result is characterized as a “rhythm”. Scientists who study these rhythms generally ask two kinds of questions: why do they occur when they do that is, what is their survival value, and how are they controlled, physiologically? Hatchling marine turtles almost always emerge from their nests at night, then crawl down the beach to the sea and migrate offshore. By doing so at night they avoid lethally warm beach sands and diurnally active predators in the shallows. But these “survival value” explanations do not account for how the turtles, digging their way upward inside the nest toward the beach surface, know that it’s dark and time to emerge. The classic explanation for how they “know” is based upon surface sand temperatures. During the day, these sands can be very warm 50° C. When hatchlings digging upward encounter these heated sands, they stop digging until the sand cools, after sunset. But these observations fail to explain why in most studies, hatchlings rarely emerge from their nests at dawn or in the early morning, when the sand is still cool. To account for those observations, we hypothesize that the turtles must also possess a time sense that inhibits emergence during inappropriate times, such as shortly before or after sunrise.
