Enzyme shown to help protect genomic stability

... other DNA segments. In the telomeres, such events may accelerate aging or trigger cancer in humans." "We have identified a molecular mechanism to explain how this enzyme helps keep telomeric DNA silenced and potentially protects the genome from destabilizing activity," says N.C. Tolga Emre, a graduate ...

BRCA1 causes ovarian cancer through indirect, biochemical route

...cer is the result of some biochemical problem that may be correctable or preventable. That's what makes this finding so exciting." Dubeau points out that women with BRCA1 mutations are also predisposed to cancers of the fallopian tubes, and that the mice with mutated BRCA1 genes in their granulosa cells...

Ferrieri believes there may be an increase in compounds that resist microbial attack after plants have soaked up atmospheric carbon dioxide, therefore countering the effects of fossil-fuel combustion. This is a strategy of carbon sequestration -- the provision of long-term stor...
