HIP1 mediates prostate carcinogenesis and progression through STAT3 signalling

ABSTRACT: Overexpression of HIP1 has been associated with fibroblast transformation, increasing grades of prostate cancer (CaP), and biochemical relapse. Here we demonstrate cellular transformation and phenotypic effects of HIP1 overexpression in a benign prostate epithelial cell line to be dependent on STAT3 signalling. In vivo xenografts confirmed the cellular transformation phenotype and revealed serum GDF15 to be a marker of CaP in our model. STAT3 signalling was in part, dependent on HIP1 expression, in a highly invasive, metastatic and androgen receptor (AR) negative DU145 cell line, Immunohistochemistry of a large prostate tissue microarray (TMA) revealed increased HIP1 and reciprocal GDF15 expression to adversely affect outcome warranting further studies to assess HIP1 and GDF15 as biomarker
