Primitive Yeast Yields Secrets Of Human Cholesterol And Drug Metabolism

...ritory for their search and giving them a telltale marker (the cholesterol) to track. Reasoning that whatever controls the P450s likely would be turned on and off at roughly the same time as the P450 enzymes themselves, the researchers found that Dap1 does just that in the yeast cell. To figure out wha...

New Test May Better Identify Certain Colorectal Cancer Types

...ers test for these mutations by looking for a gene marker called microsatellite instability, which is caused by those gene defects. These mutations indicate that the cancer is likely an inherited condition called Lynch syndrome. It's important to identify patients with Lynch syndrome because they and their ...

Severe Form of “Enlarged Prostate” Disease Discoverd

... “Our experiments show that the expression of this marker is related to the presence of the severe form of BPH and not to the size of the prostate or to the presence or risk of prostate cancer,” says Getzenberg. “What we’re looking at is two diseases: BPH that produces more mild symptoms and is less likely ...
