CRTC2 switch controls liver glucose production, role in type II diabetes

Posted: 08 Apr 2012 05:02 PM PDT

According to Salk researchers a molecular switch, CRTC2, controls liver glucose production and may represent a new avenue for treating insulin-resistant type II diabetes.

In their extraordinary quest to decode human metabolism, researchers at the Salk Institute for Biological Studies have discovered a pathway that regulates the liver's production of glucose---- the simple sugar that is the source of energy in human cells and the central player in diabetes.

Deriving DNA information from RNA - Privacy at risk?

Posted: 08 Apr 2012 04:44 PM PDT

Researchers have developed a method to derive enough DNA information from non-DNA sources—such as RNA—to clearly identify individuals whose biological data are stored in massive research repositories. The approach may raise questions regarding the ability to protect individual identity when high-dimensional data are collected for research purposes. A paper introducing the technique appears in the April 8 online edition of Nature Genetics.
