AR regulated transcriptome in prostate cancer cells


ABSTRACT: It has been well established that the transcription factor androgen receptor (AR) is obligatory for prostate cancer (PCa) development and progression, but the precise role of the AR in these processes is still unclear. To dissect the role of AR in shaping the transcriptome of prostate cancer cells, RNA-seq data were obtained from AR-positive LNCaP cells treated with various regimens to manipulate endogenous AR signaling. LNCaP cells were cultured in normal medium containing fetal bovine serum (FBS) to represent an androgen-dependent (AD) growth state. To mimic the clinical androgen-deprivation-therapy (ADT) settings, cells were grown for 4 days in conditions of either depletion of androgen (i.e., medium containing charcoal:dextran stripped fetal bovine serum (CDSS)) or the presence of AR antagonist Enzalutamide (MDV3100, 10 μM) to represent androgen-independent (AI) growth states. Aside from the pharmaceutical modulations, we also utilized siRNA to knockdown AR. To examine the direct effects of AR signaling on gene transcription and splicing, cells were primed with CDSS for 3 days followed by treatment of 10nM dihydrotestosterone (DHT) for 8-9 hrs. Deep sequencing of rRNA-depleted total RNAs was performed in biological duplicates on abovementioned LNCaP cultures. Overall design: Quantification of RNA expression in prostate LNCaP cancer cells treated with various regimens to manipulate endogenous AR signaling.
