Summary
Ribosome synthesis and function are critical for normal cell growth and division and hence this process is exquisitely regulated. Conversely, de-regulated cell growth can lead to cancer. We have identified new roles for the AKT and SGK families of kinases in controlling this process. This proposal aims to establish the mechanisms by which these enzymes control ribosome synthesis to better understand growth control and to provide insight for targeting these pathways in growth driven cancers.
Molecular Regulation Of The Serine-Threonine Kinase ULK1 In Autophagy

Summary
Autophagy or self eating is a basic cellular process and can have either beneficial or adverse effects in cancer. It is essential to determine the status of autophagy in patients before considering drugs that block autophagy for therapy. A protein called ULK1 is needed for autophagy and may emerge as a pathological marker for autophagy in cancer as well as a potential drug target. This grant proposal will study ULK1 regulation and will lay the scientific foundation for its medical application.
An AMPK Myristoyl Switch Controls AMP Mediated Metabolic Stress Signaling

Summary
This project is investigating an enzyme called AMP-activated protein kinase that plays a pivotal role in controlling how our bodies regulate energy metabolism in response to exercise and diet. Improved understanding of how this enzyme is regulated may provide new therapeutic methods for mimicking the beneficial effects of diet and exercise to treat multiple metabolic diseases including obesity, Type 2 diabetes and cardiovascular disease.
