(Submitter supplied) Androgen receptor (AR) splice variants (ARVs) are implicated in developing castration-resistant (CR) prostate cancer (CRPC). Little is known about the ARV-mediated transcription program in CRPC. We identified ARV-preferred binding sites (ARV-PBS) and unique transcriptome in CRPC cells. ARVs preferentially bind to enhancers located in nucleosome-depleted regions with the full AR-response element (AREfull), while full-length AR (ARFL)-PBS are enhancers resided in closed chromatin regions with the composite FOXA1-nnnn-AREhalf motif. more...

(Submitter supplied) The spliced variant forms of androgen receptor (AR-Vs) have been identified recently in castration-resistant prostate cancer (CRPC) cell lines and clinical samples. Here we identified the cistrome and transcriptome landscape of AR-Vs in CRPC cell lines and determine the clinical significance of AR variants regulated gene.The AR variants binding sites can be identified in 22Rv1 cell line in the absence of androgen. more...

(Submitter supplied) We report RNA sequencing data on serial biopsies of prostate cancer VCaP xenografts as the tumors pass from androgen-sensitivity (Pre-Cx), to castration resistance (CRPC, castration resistant prostate cancer), onto resistance to dual therapy with abiraterone plus enzalutamide (AER). From comparison of these RNAseq data sets, we were able to determine differentially expressed genes between the AER/CRPC and Pre-Cx states that could mediate resistance to androgen deprivation therapies.

(Submitter supplied) Continued androgen receptor (AR) signaling is an established mechanism underlying castration-resistant prostate cancer (CRPC), and suppression of AR signaling remains a therapeutic goal of CRPC therapy. Constitutively active androgen receptor splicing variants (AR-Vs) lack the AR ligand-binding domain (AR-LBD), the intended target of androgen deprivation therapies (ADT) including new CRPC therapies such as abiraterone and MDV3100. more...

(Submitter supplied) Building on the observation that metastatic, castration-resistant prostate cancer (CRPC) correlates with activation of Src-family tyrosine kinases, we showed that the expression of activated Src renders LNCaP androgen-independent. Here, we report on RNA-seq and/or AR ChIP-seq analyses of LNCaP, LNCaP[Src], VCaP, 22Rv1 cells grown in the presence or absence of 10 nM DHT for 16h, or LuCaP35.1 tumors grown in androgen-supplemented vs. more...

(Submitter supplied) The constitutively active androgen receptor (AR) splice variant 7 (AR-V7) plays an important role in the progression of castration-resistant prostate cancer (CRPC). Although biomarker studies established the role of AR-V7 in resistance to AR-targeting therapies, how AR-V7 mediates genomic functions in CRPC remains largely unknown. Using a ChIP-exo approach, we show AR-V7 binds to distinct genomic regions and recognizes a full-length androgen-responsive element in CRPC cells and patient tissues. more...

(Submitter supplied) Although AR-V7 has been intensively studied, it remains unclear whether AR-V7 and other AR splicing variants can specifically activate a distinctive transcriptional program from the full-length AR (AR-FL), and whether AR-V7 may play a role in accelerating the metastatic progression of castration-resistant PCa (CRPC). In this study, we hypothesize that AR-V7 can drive a distinct transcription program from AR-FL in CRPC condition. more...

In this study, we hypothesize that AR-V7 can drive a distinct transcription program from AR-FL in CRPC condition. To test this, we used LNCaP model with inducible overexpression of AR-V7 or AR-FL to examine the effects of AR-V7 overexpression or AR-FL overexpression stimulated with DHT for 4 hours on AR-V7 or AR-FL cistromes. We also studied the effects of AR-V7 on cistromes of pioneer factor FOXA1 and active histone marker H3K27ac, and the function of phosphorylation at Ser81 on AR-V7 function in CRPC.

(Submitter supplied) In order to define the genes responsible for the growth and survival of a human castration-resistant prostate cancer cell line, a short term (doxycycline inducible) knockdown system was developed and utilized. Three independent 22Rv1 cell isolates were derived for each of the following doxycycline-inducible shRNAs (shGFP, shAR3, and shVav3) (AR3 = AR-V7). The cells were grown in androgen depleted conditions, plus or minus doxycycline, for three days. more...

(Submitter supplied) Endocrine therapies in prostate cancer (PCa) treatment block androgen receptor (AR) function, but are palliative as tumors progress to a lethal, castration-resistant state (CRPC). CRPC remains dependent on AR signaling, which can act through the full-length AR (ARfl) or constitutively active splice variants, e.g. ARv7. We show here that both ARfl and ARv7 bind to the same genomic region and heterodimerize in a CRPC cell line model, but regulate distinct transcriptomes. more...
