Correlation between specific carcinogenic chemicals and specific mitotic defects and the restorative role of antioxidants
- Date Issued:
- 2009
- Summary:
- The progression of cancerous cells towards a more aggressive tumor can be linked to external elements called carcinogens. The goal of this project is to examine the correlation between exposure to specific carcinogens and an increase of mitotic defects. These defects can manifest as lagging chromosomes, multipolar spindles, and anaphase bridges. Some of these instabilities are associated with the formation of reactive oxygen species (ROS), which are known to damage DNA. The potential for damage to the genome can be averted via antioxidants. Using the oral cancer cell line UPCI:SCC103, we established a baseline for the mitotic defects in the absence and presence of various ROS-inducing carcinogens using DAPI-stained fixed cells examined by immunofluorescent microscopy, The cells were treated with varying concentrations of the antioxidants, Vitamin C, (Sb(B-Carotene, and Vitamin E. The reactive oxygen scavengers significantly reduced the number of mitotic defects. A possible link between the carcinogens and lagging chromosomes was established.
