Among androgen deprivation therapy (ADT), radiation therapy is an approved treatment either for early stage local PCa, but also for metastatic M1 stage PCa. However, tumour relapse is a frequent event that affects about 80% of patients undergoing prior treatment. There is increasing evidence that the occurrence of cancer stem cells (CSC) may play an important role in therapy resistance, in particular also in radioresistance. However, our knowledge on the mechanisms of radiores...

Chronic inflammation and high expression of pro-inflammatory cytokines, such as Interleukin-6 (IL6), are well-known risk factors for prostate cancer (PCa). IL6 is known to activate the androgen receptor (AR) and has been implicated in development of castration resistance. Therefore, we wanted to investigate the interaction of AR and IL6 signalling and the effect on anti-androgen treatment. We could confirm IL6 mediated activation of the AR on 3 AR target genes in presence of R...
