Description
Recent data suggests that repression of the Type II TGF-B Receptor (Tgfr2) repression in human lung adenocarcinoma is important for progression from noninvasive to invasive adenocarcinoma. To test this hypothesis in a animal model of non-invasive lung cancer, we generated an inducible, lung specific Tgfbr2 knockout model in the oncogenic Kras mouse.

Description
STAT3, an essential transcription factor with pleiotropic functions, plays critical roles in the pathogenesis of autoimmunity. Despite recent data linking STAT3 with inflammatory bowel disease, exactly how it contributes to chronic intestinal inflammation is not known. Using a T cell transfer model of colitis we found that STAT3 expression in T cells was essential for the induction of both colitis and systemic inflammation. STAT3 was critical in modulating the balance of T helper 17 (Th17) and regulatory T (Treg) cells, as well as in promoting CD4+ T cell proliferation. We used chromatin immunoprecipitation and massive parallel sequencing (ChIP-Seq) to define the genome-wide targets of STAT3 in CD4+ T cells. We found that STAT3 bound to multiple genes involved in Th17 cell differentiation, cell activation, proliferation and survival, regulating both expression and epigenetic modifications. Thus, STAT3 orchestrates multiple critical aspects of T cell function in inflammation and homeostasis.
Publication Title
Diverse targets of the transcription factor STAT3 contribute to T cell pathogenicity and homeostasis.
