Carsten Schmitz-Peiffer undertook his PhD with Professor Dick Denton at Bristol University (UK), where he investigated insulin signal transduction and the regulation of fat cell metabolism. He then joined the Garvan Institute to investigate mechanisms by which lipid oversupply could interfere with normal insulin action. His research showed an association between protein kinase C activation and lipid-induced insulin resistance in skeletal muscle. Subsequently he demonstrated a causative link between intracellular accumulation of the lipid intermediate ceramide and the inhibition of insulin action caused by the saturated fatty acid palmitate. It is thus clear that different fatty acids act through different mechanisms to reduce insulin sensitivity.
In addition, the study of mice deficient in specific protein kinase C isoforms has indicated that these enzymes play multiple and unexpected roles in the control of glucose and lipid metabolism, beyond the mere inhibition of proximal insulin signalling as currently widely assumed, and the understanding of the diverse mechanisms involved is a major focus of his work. His research group employs animal models of insulin resistance in combination with transgenic mice, as well as proteomic and lipidomic approaches at both the in vivo and in vitro level, to generate new insights into the molecular mechanisms involved in the defective insulin action seen in obesity and Type 2 diabetes.

My Research Activities
Investigating the relationship between insulin resistance and lipid metabolism
A major factor in the development of type 2 diabetes is the insulin resistance of tissues such as liver and skeletal muscle. Although the mechanisms involved are not fully understood, there is a close association between insulin resistance and increased lipid availability. Our lab has previously identified the roles played by protein kinase C (PKC) and specific inhibitory lipid intermediates, especially the sphingolipid ceramide.
We employ in vivo models and knockout mice, as well as cell culture systems and proteomic and lipidomic technologies, to investigate novel pathways and identify new strategies for type 2 diabetes therapies. We also pursue the translation of our findings into clinical settings, using novel or existing drugs that target PKCs and inhibitory lipids to improve glucose homeostasis.
Our research goals are:
- To define the interactions between PKC, lipid metabolism and insulin action.
Our research has shown that the currently-held view that PKCs act solely to suppress proximal insulin signal transduction is an oversimplification. We will extend our novel findings, which show that these kinases and their specific downstream mediators play key roles in the control of lipid storage and oxidation in liver, and other insulin target tissues. This work will have relevance not only to diabetes but also hepatic steatosis, cardiovascular disease and the metabolic syndrome.
- To examine the effectiveness of targeting key molecules for the treatment of diabetes, using new and existing drugs.
We will further pursue the translation of our basic research findings into clinical settings. We will test existing inhibitors of PKC isoforms in vivo and in vitro, to determine their effectiveness in improving insulin action. Because of specificity problems with targeting kinase catalytic activity, we have also initiated a project to generate novel PKC inhibitors using other strategies.
