T Lymphocyte mRNA Stability

Research in my laboratory focuses on the role of mRNA decay in regulating T lymphocyte activation and function. Many genes that are important for cell growth and immune function are turned on at precise times and turned off at precise times. Dysregulated expression of many of these genes, including proto-oncogenes and cytokine genes, occurs in disease states such as cancer, autoimmunity, or immunodeficiency. One mechanism that cells use to turn off gene expression is specific degradation of mRNA within the cytoplasm. We have recently shown that the rate of decay of many transcripts encoding important regulatory proteins changes upon cellular activation, and these changes in mRNA decay can have dramatic effects on overall gene expression. Our goal is to understand the biochemical mechanisms that regulate mRNA decay and to understand the role of mRNA decay in regulating gene expression in disease states such as malignancy or virus infection.
