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. …

New plan of attack in cancer fight: Two-drug combination, under certain circumstances, can eliminate disease

As described in a paper recently published in eLife, Martin Nowak, a professor of mathematics and of biology and director of the Program for Evolutionary Dynamics, and co-author Ivana Bozic, a postdoctoral fellow in mathematics, show that, under certain conditions, using two drugs in a "targeted therapy" — a treatment approach designed to interrupt cancer’s ability to grow and spread — could effectively cure nearly all cancers. Though the research is not a cure for cancer, Nowak said it does offer hope to researchers and patients alike. "In some sense this is like the mathematics that allows us to calculate how to send a rocket to the moon, but it doesn’t tell you how to build a rocket that goes to the moon," Nowak said…
