Mining the Mitochondria for Clues to Cell Survival Mechanisms

This article was originally published in Start Up

Executive Summary

Researchers have identified a protein in the mitochondria -- where cells generate the energy needed to drive biological processes -- that is dramatically upregulated by nutrient restriction. It appears to protect the cell from stress, in keeping with observations that caloric restriction diets slow aging. The researchers go on to show that a set of other proteins activated in turn by this process may be targets for the development of therapies for neurodegenerative diseases and diabetes.

Clock Genes Influence Metabolism: A First Link With Glucose Production

It's common sense that Circadian rhythms manifest at the molecular level, given the obviously different metabolic functions while awake versus when asleep. Now, a group has shown that one of the body's "clock genes" helps regulate the production of new glucose in the liver. The findings could be applied to the discovery of novel treatments for type 2 diabetes and because the mechanism may also regulate signaling activities in other cell types, potentially alter the course of other diseases.

Sirtris Satisfies GSK's M&A Appetite

Pathway-oriented platforms are rare, and dealmaking around them can be complicated: partner too early or for too little and you risk giving away the store. But Sirtris pulled it off, via M&A, when GSK tendered a whopping $720 million for it in April. The deal is another example of Pharma's interest in platform biotechs and its hunger for innovation. But the unique nature of Sirtris's platform -- broad, but around a single set of biological targets -- makes it more one-off than trend-setting.
