Signal transducer and activator of transcription-3 (STAT-3) is one of six members of a family of transcription factors. It was discovered almost 15 years ago as an acute-phase response factor. This factor has now been associated with inflammation, cellular transformation, survival, proliferation, invasion, angiogenesi…

Lymphomas arising from NK or γδ-T cells are very aggressive diseases and little is known regarding their pathogenesis. Here we report frequent activating mutations of STAT3 and STAT5B in NK/T-cell lymphomas (n=51), γδ-T-cell lymphomas (n=43) and their cell lines (n=9) through next generation and/or Sanger sequencing.…

IL-12 and IL-4 direct T cell development toward Th1 and Th2 phenotypes, respectively. While IFN-gamma and IFN-alpha have been reported to regulate Th1 development as well, the mechanism and cellular locus of their effects are unclear. In this study, we use a TCR-transgenic system to examine the actions of these cytoki…

BACKGROUND: Members of the p47 (immunity-related GTPases (IRG) family) GTPases are essential, interferon-inducible resistance factors in mice that are active against a broad spectrum of important intracellular pathogens. Surprisingly, there are no reports of p47 function in humans. RESULTS: Here we show that the p47 G…

Metastasis of tumor cells is a complex challenge and significantly diminishes the overall survival and prognosis of cancer patients. The epithelial-to-mesenchymal transition (EMT) is a well-known mechanism responsible for the invasiveness of tumor cells. A number of molecular pathways can regulate the EMT mechanism in…

Implantation is the process by which the blastocyst becomes intimately connected with the maternal endometrium/decidua. The independently developing preimplantation blastocyst then becomes dependent on the maternal environment for its continued development. Although the factors involved in the regulation of blastocyst…
