Androgen Receptor Splice Variants Contribute to the Upregulation of DNA Repair in Prostate Cancer

Abstract

The expression of AR splice variants such as AR-V7 in PCA patients following ADT might be a reason for reduced or absent therapy effects in patients on additional PARP inhibition due to the modulation of DNA repair gene expression. Consequently, AR-Vs should be further studied as predictive biomarkers for therapy response in this setting.
