The regulation of HAS3 by miR-10b and miR-29a in neuroendocrine transdifferentiated LNCaP prostate cancer cells.

Prostate cancer (PCa) is the second most common type of cancer in male worldwide. During neuroendocrine transdifferentiation (NETD), PCa cells are able to differentiate into androgen-independent neuroendocrine-like (NE-like) tumor cells, which are associated with reduced survival rates in PCa patients. The molecular processes underlying NETD have not been clarified yet, but miRNAs could play a potential role. MiRNAs are short, single-stranded, non-coding RNA molecules that regulate gene expression post-transcriptionally by binding to the 3′-untranslated region (3′UTR) of their target mRNAs. This study aimed to explore the possible relevance and function of the transmembrane Hyaluronan Synthase 3 (HAS3) and miR-10b as well as miR-29a during NETD.
