Common genetic polymorphisms induce major differentiations in the metabolic make-up of the human population, according to a paper published November 28 in the open-access journal PLoS Genetics.

Molecular partnership controls daily rhythms, body metabolism

A research team led by Mitchell Lazar, MD, PhD, Director of the Institute for Diabetes, Obesity, and Metabolism at the University of Pennsylvania School of Medicine, has discovered a key molecular partnership that coordinates body rhythms and metabolism.

Metabolism accounts for why natural selection favors only some species

Why are some species of plants and animals favored by natural selection? And why does natural selection not favor other species similarly?

Computer scientists are cracking the code on the metabolism of human tissues

Scientists know that different normal and diseased tissues behave differently. But a method that tells them just how they do so may one day give medical science a new way to fight obesity, hypertension, diabetes and other dangerous disorders of the metabolism.

Metabolic insight to illuminate causes of iron imbalance

New insight into key players in iron metabolism has yielded a novel tool for distinguishing among root causes of iron overload or deficiency in humans, the researchers report in the August issue of Cell Metabolism, a publication of Cell Press.

Circadian rhythm-metabolism link discovered

UC Irvine researchers have found a molecular link between circadian rhythms – our own body clock – and metabolism. The discovery reveals new possibilities for the treatment of diabetes, obesity and other related diseases.

Missing link found between circadian clock and metabolism

Two new research studies have discovered a long sought molecular link between our metabolism and components of the internal clock that drives circadian rhythms, keeping us to a roughly 24-hour schedule. The findings appear in the July 25th issue of the journal Cell, a publication of Cell Press.

Metabolomics sheds new light on question

harminka — Wed, 02 Jul 2008 09:10:14 -0500

Scientists from the Institute for Bioinformatics and Systemic Biology of the Helmholtz Zentrum München and the Faculty for Biology of the Ludwig-Maximilians-Universität have shown that biological indicators for diseases caused or influenced by environmental factors can be detected by the systemic analysis of the body’s metabolism (metabolomics).

Duke scientists show why cells starved of iron burn more glucose

harminka — Mon, 09 Jun 2008 12:19:59 -0500

Duke University Medical Center scientists have found a mechanism that allows cells starved of iron to shut down energy-making processes that depend on iron and use a less efficient pathway involving glucose. This metabolic reshuffling mechanism, found in yeast cells, helps explain how humans respond to iron deficiency, and may help with diabetes research as well.

Researcher figures out factors that make bacteria more modular

Many bacteria break their metabolic processes into chunks. That may be logically tidy, but it’s often metabolically inefficient. Researchers have now figured out the factors that tend to make bacteria more modular.
