Scientist Identifies Gene Linked to Metabolic Syndrome

Normally, SIRT3 sets off a complex chain of events to transform fat into energy at the cellular level. But deleting the SIRT3 gene disrupted this chain, and fat deposits weren't broken down as they should have been.

A scientist at the Gladstone Institutes has discovered how a gene known as SIRT3 contributes to a suite of health problems sweeping across America, offering new insight into how to combat these potentially fatal conditions.

 

In a paper published in Molecular Cell, Gladstone Senior Investigator Eric Verdin, MD, describes how SIRT3, when switched off, accelerates the build-up of fats throughout the body. This can lead to obesity, high blood pressure and a decreased ability to process sugar—the combination of which is known as the "metabolic syndrome." Metabolic syndrome significantly increases one's risk for developing heart disease and diabetes.

 

"Estimates indicate that one-third of Americans have the metabolic syndrome, and more develop it each year," said Warner Greene, MD, PhD,
