HOTAIR is a REST-regulated lncRNA that promotes neuroendocrine differentiation in castration resistant prostate cancer
Long non-coding RNAs (lncRNAs) are emerging as novel diagnostic markers of prostate cancer (PCa) and new determinants of castration-resistant PCa (CRPC), an aggressive and metastatic form of PCa. In addition to androgen receptor (AR) signaling, neuroendocrine differentiation (NED) is associated with CRPC. Recent reports demonstrate that the downregulation of repressor element-1 silencing transcription factor (REST) protein is a key step in NED of PCa cells. Here, we report HOTAIR as a novel REST-repressed lncRNA that is upregulated in NED PCa cells and in CRPC.
