Protein Kinase C Epsilon Deletion in Adipose Tissue, but Not in Liver, Improves Glucose Tolerance

A new study by Australian researchers, out today, is challenging what we know about the causes of diabetes. The new research points to fat tissue as a source of disease, and widens our understanding beyond the traditional focus on liver and pancreas as the main culprits. The findings, uncovered in mice, are published in the high-impact journal Cell Metabolism.

The new research is centred around the surprising finding that protein kinase C epsilon (PKCε), known to be involved in diabetes, isn’t acting in the liver or the pancreas as was once assumed. Researchers have long known that PKCε is important for the development of diabetes...

Map of thousands of genes suggests new targets for diabetes. The scientists demonstrated knocking out clock genes led to obesity and type 2 diabetes, but they still had much to learn if they wanted to manipulate clock action to treat the conditions.”We knew that the pancreas didn’t work if we removed these clock genes, but we didn’t know how the genes were affecting the normal function of the pancreas,” said Dr. Joe Bass.

Clock genes are responsible for producing transcription factors, which help tell a cell how to function. In the new study Bass’s laboratory revealed thousands of genes in the pancreas that the clock’s transcription factors control in rhythm with the planet’s daily rotation from light to dark...
