A key mechanism of persistent cell survival under testosterone suppression in advanced prostate cancer (PC) is continued Androgen Receptor (AR) activation. This results from AR mutation, overexpression, hyper-activation, and/or expression of constitutively-active AR transcript variants (AR-Vs). AR has an unusually long 3’ untranslated region (3’UTR), which performs vital regulatory roles but is remarkably understudied. Its contribution to continued AR activation unde...

Prostate Cancer (PC) affects 1-in-6 men in the UK, and obesity 1-in-3, with rates of both increasing. High-fat diet is linked with increased risk of PC death, and volume of peri-prostatic adipose tissue (PPAT) is associated with increased risk of lethal PC/reduced therapy response. Despite this, molecular mechanisms underpinning obesity-driven PC remain poorly-understood. This is important since weight-gain and central obesity are major side-effects of PC trea...

MiR-346 is an Androgen Receptor (AR)-activating miR that associates with DNA damage response (DDR)-linked transcripts in prostate cancer (PC). MiR-346 induces rapid and extensive DNA damage in PC cells through chromatin association, activation of transcription, R-loop formation and DNA replication stress, leading to checkpoint activation and cell cycle arrest. MiR-346 interacts with lncRNA, NORAD, in PC cells, which functions to maintain mitosis, DDR, and chromosomal integrity...
