Project description:Transriptome analysis of VCAP and CWR22-Pc cell lines after concomittant treatment with androgen with bicalutamide and enzalutamide
Project description:Transriptome analysis of prostate tumors from Hi-Myc mouse prostates 3 days after castration or treatment with bicalutamide or enzalutamide
Project description:The goal of this analysis is to profile AR-regulated genes, especially non-coding RNAs in three androgen sensitive prostate cancer cell lines, MDA-PCA-2B, LNCaP and VCaP. The two cell lines were serum-starved first, followed by dihydrotestosterone (DHT) stimulation or treated with Enzalutamide (AR inhibitor) without starvation. Transcriptome profiling was generated by RNA-sequencing from polyA-selected RNA. These experiments are followed by knock-down experiments of AR and ARlnc1 in MDA-PCA-2B, and also Enzalutamide (anti-androgen) treatment of LNCaP cells.
Project description:Gene expression in LNCaP cells after treatment with the androgen receptor targeting drugs bicalutamide (BIC), enzalutamide (ENZ) and apalutamide (ARN) in the presence or absence of dihydrotestosterone (DHT).
Project description:We report the androgen receptor recruitment to the chromatin of androgen responsive prostate cancer cell lines, LNCaP-1F5 and VCaP in response to physiological androgen 5a-dihydrotestosterone (DHT) using ChIP-sequencing. We compare the AR recruitment by DHT to that by partial agonist/antagonist cyproterone acetate (CPA), mifepristone (RU486) and bicalutamide (Bica) in LNCaP-1F5 cells. We also report the role of glucocorticoid receptor recruitment in presence of dexamethasone (Dex) in androgen responsive prostate cancer cells. The AR and GR cistrome analysis is subsequently compared with gene expression data and RNA Pol II analysis. The ChIP-seq has been performed using AR, GR, RNA Pol II antibodies.

Examination of AR and GR binding sites in LNCaP-1F5 and VCaP cells in presence of DHT and Dex respectively. Further analysis of AR binding sites in LNCaP-1F5 cells treated with partial agonist/antagonists, CPA, RU486 and Bica. Additionally RNA Pol II mapping is performed in cells treated with DHT and Dex.
Project description:Enzalutamide (ENZ) is an inhibitor of the androgen receptor (AR) widely used in managing castration-resistant prostate cancer (CRPC). However, ENZ is not curative due to the resistance CRPC inevitably develops. We hypothesize that there are commonly necessary elements of ENZ resistance in cells with different genetic mutations and treatment history. This study aims to identify differentially expressed genes in Enzalutamide-sensitive (ENZS) and ENZ-resistant (ENZR) C4-2B, CWR-R1, VCaP human prostate cell lines. We have identified 114 commonly upregulated genes in all three ENZR celll lines, which will be subjected to further investigation for their roles in ENZ resistance.
