  • Description: Resistance to androgen receptor (AR)-targeted therapies in prostate cancer (PC) is a major clinical problem. A key mechanism of treatment resistance in advanced PC is the generation of alternatively spliced forms of the AR termed AR variants (AR-Vs) that are refractory to targeted agents and drive tumour progression. Our understanding of how AR-Vs function is limited due to difficulties in distinguishing their discriminate activities from full-length AR (FL-AR). The CWR22Rv1-AR-EK (Androgen Receptor-Exon Knockout) cell line is a prostate cancer cell line which is knockout for FL-AR (by CRISPR) but retains expression of all endogenous AR-Vs making it a valuable model for the study of receptor splice variants. This new derivative is dependent upon AR-Vs for growth and is refractory to all FL-AR-targeting agents.
