Systemic lupus erythematosus (SLE) is a complex autoimmune disease with multifactorial etiopathogenesis that primarily afflicts women in the childbearing years. Hormones especially estrogen are implicated in the pathogenesis of disease, however the precise molecular events regulated by estrogen in immune cells are not well understood. T cells play a key role in SLE pathogenesis and display abnormalities in gene expression and function. We previously identified a novel role for the multifunctional protein serine arginine rich splicing factor 1 (SRSF1) in T cell gene regulation and function. We have shown that SRSF1 promotes IL-2 production in normal T cells, and its overexpression into SLE T cells rescues IL-2 production. SRSF1 expression is decreased in SLE T cells, and associates with severe disease activity. These results suggest that the deficiency of SRSF1 is an important molecular defect in immune-mediated disease. However, not much is known about the regulation of SRSF1 in T cells, and if or how hormones/estrogen may contribute to its expression. The student will be involved in the project to determine mechanisms of transcriptional and post-transcriptional gene regulation of SRSF1 in response to estrogen in human T cells and cell lines. Techniques will involve cell culture, transfections, RT-PCR, western blotting, reporter-luciferase assays and flow cytometry. Prior basic research lab experience is preferred.
