Researchers at The Rockefeller University's Laboratory of Biochemistry and Molecular Biology have uncovered the mechanism that enables breast cancer cells not only to withstand environmental stress, but to turn it to their advantage. They have just published their findings in Nature Chemical Biology.
For ID creationists, these findings pose yet another challenge—one typically ignored or waved away as the consequence of ‘sin’, neatly exposing the Discovery Institute’s attempt to persuade US legislators and educators that ID is a genuine scientific alternative. No real science explains inconvenient evidence by invoking fundamentalist doctrine or unevidenced forces inherited from ancient superstition.
The Rockefeller University team has shown that breast cancer cells can override a regulatory factor that normally controls gene expression. The transcription of DNA into mature messenger RNA involves the enzyme RNA polymerase II (POL II), whose activity depends on around 30 subunits. One of these, MED1, normally carries acetyl groups. Without those acetyl groups, MED1 loses its ability to regulate POL II, allowing the enzyme to transcribe genes that help cancer cells survive. Environmental stress deacetylates MED1. In essence, conditions such as low oxygen or elevated temperature—deadly to normal cells—can instead make cancer cells more resilient.
