    My lab is interested in mechanisms of signal transduction and gene regulation in different developmental and disease contexts. One of the current projects is to analyze the role of alternative splicing in liver development, metabolism and disease. They have created hepatocyte-specific knockouts of the splicing factors SRSF1 and SRSF3. They have previously these factors regulate insulin receptor splicing and promote inclusion of a small cassette exon 11 in the C-terminus of the hormone-binding domain. Deletion of SRSF3 impairs splicing of selected RNA isoforms resulting in inhibition of hepatocyte maturation, impairment of lipid and glucose metabolism, and generation endoplasmic reticulum stress. These defects result in a continual regeneration phenotype with increased proliferation and apoptosis, cellular pleiomorphism, eventually leading to fibrosis and hepatocellular adenoma formation and progression to hepatocellular carcinoma that metastasizes to the lung. This knockout thus represents a valuable model for human HCC as many of the same genes are altered.
    Another goal of our research is to investigate how changes in GnRH pulse frequency alter gene expression and secretory function in pituitary gonadotropes. Much of the work is based on the application of genomic technologies to understand the changes in mRNA expression and cell phenotype during response to pulsatile hypothalamic stimulation. We have used these genomic approaches to generate models of regulation that we are in the process of testing experimentally. We are also investigating how metabolic derangements alter reproductive function through effects on hypothalamic-pituitary signaling.
    My lab is also investigating the effects of obesity on breast cancer initiation and progression. Mouse mammary tumor cells form larger, more aggressive tumors in obese mice. The same acceleration is seen with both genetic and diet-induced obesity. The mammary fat pad in the obese mouse expresses high levels of TNFa and we have shown that this cytokine stimulates cancer cell proliferation in vitro. The lab is studying how omega-3 fatty acids, which are anti-inflammatory, can reverse the obesity effect on breast cancer growth.
