Short-wave UV light (UVB and UVC) causes transition mutations at dipyrmidine sequences (ref.). In the work presented on KNSTRN quoted by the OP the authors report that 19 from a panel of 100 squamous cell carcinomas (SCC) contained a mutation in KNSTRN (and furthermore three of these contained no other mutation across the six genes that were analysed (Fig. ...

This is actually a bad idea for severeal reasons: First it is not a good idea to tamper with genes, especially not with ones which are involved in the regulation of mitosis and the correct segregation of sister chromatids. Remember that a one amino acid exchange because of a C to T transition causes the problems with SCC? Into what do you want to change the ...

The question and link imply that if cooking with Teflon generates carcinogens that carcinogens then always lead to cancer. This is not always true. In some cases exposure to carcinogens may signal protective pathways. Oncogenesis and exposure to both genotoxic and non-genotoxic carcinogens are not always positively correlated. Cooking with Teflon influences ...

Teflon is a polymer of perfluorooctanoic acid (PFOA) and related compounds. PFOA is thought to be a carcinogen. I think there's an urban legend that if you really heat teflon up or burn it (it doesn't burn as flouroxides are not stable in air) that you might get some of the constituent chemicals out into the air. Once the flourocarbons are polymerized ...
