Xin-Yuan FU


Prof Fu’s laboratory is interested in molecular mechanisms of cancer angiogenesis, metastasis and stem cell and iPS cell biology. His team is primarily working on a key regulator STAT3 and epigenetic regulation induced by cytokines. They have developed a number of in vivo and in vitro model systems for these studies. The major hypothesis is that STAT3 mediates essential inflammatory functions that can cause epigenetic changes leading to tumour transformation, angiogenesis and metastasis.

Dr. Xin-Yuan Fu’s laboratory has been working on the STAT SIGNALING PATHWAY since its discovery (See Fu, PNAS 1992). Now Fu lab focuses on STAT mediated epigenetic regulation of stem / cancer cells and other diseases. In the past, we first showed that STATs regulates cell growth and survival (Chin et al., 1996, Science, Su et al., Nature, 1997). Next, we demonstrated that STAT3 is an essential regulator of immunity and inflammation (Welte et al., PNAS, 2003. Kano et al., JEM 2003). For example, STAT3 has a negative role in regulation myeloid cell lineages and mice that are deficient STAT3 in immune cells will develop inflammation and autoimmune disorders. Dr. Fu’s laboratory in the CSI now focuses on the following new directions: 1) Signals and epigenetic regulation of inflammation and cancer development; 2) Biochemical pathways and signals that regulate stem cell functions and gene programming during early developmental stages; 3) Liver development, regeneration and cancer; 4) Development and Applications of stem cells and novel therapies in major human diseases.
