Androgen Receptor splice variant V7 (AR-V7) mediates AR signalling in castration resistant prostate cancer (CRPC) [RNA-seq]
Ontology highlight
ABSTRACT: CRPC remains AR dependent. There are multiple mechanisms for reactivation of AR including expression of constitutively active AR splices variant AR-V7 (AR3). Earlier studies suggest that though the variants regulate many of the same genes as AR, they also have unique targets. Another argument is that the variant is a “weak” AR. We have used an LNCaP cell line that expresses AR-V7 in response to doxycycline (LNCaP AR-V7) to compare the activities of the two isoforms and to identify differential regulation of target genes. We also used VCaP cell line that expresses AR-V7 in response to doxycycline (VCaP AR-V7) to validate the activities of the two isoforms in an alternative prostate cancer cell line. The transcriptomes for AR and AR-V7 in these cell lines were identified using RNA-Seq.
