AR and cancer: In her talk “The interplay between CSC markers and AR in the regulation of cancer metastases and radioresistance,” Prof. Dubrovska explains why some CSC populations are resistant to therapeutic pressure such as AR deprivation therapy and how they are dynamically regulated by AR signaling [27, 57, 59, 60]. Moreover, because of the elevated expression of some essential DNA repair proteins and activation of pro-survival pathways in CSC, they are also difficult to target by RT [56–58].
