Artificial light, biological clock disruptions, increase breast cancer risk, study finds

“Exposure to artificial light leads to a significantly higher risk for developing breast cancer,” said Chunla He, a biostatistics graduate student in the UGA College of Public Health. “To decrease the use of artificial light, people should avoid working at night and implement earlier bed times.” Her research, published in the International Archives of Occupational and Environmental Health, examined key studies that included risk factors for developing breast cancer. …

“Exposure to artificial light leads to a significantly higher risk for developing breast cancer,” said Chunla He, a biostatistics graduate student in the UGA College of Public Health. “To decrease the use of artificial light, people should avoid working at night and implement earlier bed times.” Her research, published in the International Archives of Occupational and Environmental Health, examined key studies that included risk factors for developing breast cancer. “A large body of related research about circadian rhythms and breast cancer exists,” He said. “However, these studies are inconsistent and have a variety of limitations.” Under the mentorship of Sara Wagner Robb, assistant professor of epidemiology in the College of Public Health, He turned to previous studies to see what the research revealed. …

Thyroid carcinoma: Biomarker reveals cancer cause

CLIP2 serves as a radiation marker: After exposure to radiation from radioiodine, both the genetic activity and the protein expression are increased, as the scientists’ studies were able to substantiate. CLIP2 appears to be particularly significant in the development of tumours in the thyroid gland after radiation exposure…

Crucial step in DNA repair identified by researchers

Such disorders are caused by faulty DNA repair systems that increase the risk for cancer and other conditions. The findings are published in this week’s Proceedings of the National Academy of Sciences. The study was funded by the National Institute of Environmental Health Sciences. Regents Professor Michael Smerdon and post-doctoral researcher Peng Mao found that when DNA is damaged, a specific protein must first be “unbuckled” to allow easy access for the DNA “repair crew.” Without this unbuckling, entry to the damaged site is hampered by the compact arrangement of genes and protein in chromosomes called chromatin. …
