Obesity is associated with a state of chronic, low-grade inflammation that leads to insulin resistance, which is usually the first step in the development of type 2 diabetes.

If you find an inhibitor of this protein kinase, you should be able to obtain the same effect as knocking out the gene. Timothy blackwell and fiona yull of the vanderbilt university school of medicine also are co-authors. Saltiel’s team is now searching for small molecules that block ikke protein-kinase activity.

In that situation, the ikke protein kinase acts as a brake on the metabolism. Protein kinases are enzymes that turn other proteins on or off.
