Areas of Interest

We study cellular, molecular and integrative mechanisms of growth regulation.  A major focus has been growth hormone (GH) signaling to the nucleus.  We analyze signaling mechanisms for modifying transcription regulatory proteins including STATs and C/EBP beta (eg phosphorylation, acetylation), and dissect transcription regulatory complexes on target genes.  Recent work has probed reciprocal regulation by GH of the transcriptional repressor BCL6 and activator STAT5, and ChIP-Sequencing (ChIP-Seq) is identifying their roles in regulating new gene targets for GH.  Since GH can induce insulin resistance and diabetes, we combine computational and physiological approaches to identify a potential genetic program for insulin resistance.  We are also examining human growth regulation through integrative and genetic studies of a population with short stature in Papua New Guinea.
