Targeting the MLL complex in castration-resistant prostate cancer [expression]

Project description:Resistance to androgen deprivation therapies and increased androgen receptor (AR) activity are major drivers of castration-resistant prostate cancer (CRPC). Prior work has focused on targeting AR directly; however, the identification and targeting of co-activators of AR signaling remains an underexplored area. Here we demonstrate that the MLL (mixed-lineage leukemia) complex, a well-known contributor in MLL-fusion-positive leukemia, acts as a co-activator of AR signaling. AR interacts with the MLL complex via its subunit, menin. Small molecule inhibition of the menin-MLL interaction blocks AR signaling and inhibits tumor growth in vivo. Furthermore, we find that menin is up-regulated in CRPC and high expression correlates with poor overall survival. Our study identifies the MLL complex as a co-activator of AR that can be targeted in advanced prostate cancer. ASH2L / Menin / MLL1 were knocked down using shRNA /siRNA in two prostate cancer cell lines, VCaP and LNCaP.

Epigenetic Activation and alteration of chromatin structure regulated by NSD2 in metastatic castration-resistant prostate cancer (ChIP-seq)

Project description:To elucidate the regulation of NSD2 in metastatic castration-resistant prostate cancer(CRPC), we performed ChIP-seq of H3K36me2, H3K27me3, H3K4me1, H3K4me3,H3K27ac and NSD2 against castration-sensitive prostate cancer cell line LNCaP and metastatic castration-resistant prostate cancer cell lines, PC3 and DU145, respectively. In metastatic CRPC, we found specific regions of activation with epigenetic changes.

LNCAP xenograft prostate cancer progression model in NOD-SCID mice

Project description:Xenografts are useful in vivo tumour models for investigating cancer progression, therapeutic responses and predicting anti-cancer drug response in patients with cancer of a similar phenotype. We have generated bulk RNA-seq data from LNCaP xenografts of a large and well-annotated prostate cancer progression study, investigating responsiveness and subsequent resistance to therapies targeting the androgen receptor (AR). LNCaP xenograft tumour establishment and initial growth are dependent on androgens in male mice (PRE-CX / pre-castration group). Upon castration, AR activity and tumour growth are suppressed (POST-CX / post-castration group), however, this initial responsiveness to castration reproducibly gives way to castration-resistance (CRPC / castration-resistant prostate cancer). Further treatment of CRPC with the AR targeting drug enzalutamide (ENZ) initially provides a therapeutic response (ENZ Sensitive; ENZS), however, resistance emerges in time (ENZ Resistant; ENZR).

Transcriptome profiling of Olaparib-resistant (OlapR) prostate cancer cell lines

Project description:Acquisition of resistance to the PARP inhibitor, Olaparib, constitutes a major challenge for the treatment of advanced prostate cancer. The purpose of this study was to identify molecular targets responsible for the development of acquired Olaparib resistance in advanced prostate cancer. Towards this goal, next-generation sequencing (NGS)-based gene expression profiling (RNA-Sequencing; RNA-Seq) was performed on castration-sensitive prostate cancer (CSPC)/Olaparib-sensitive LNCaP cells, castration-sensitive prostate cancer (CSPC)/Olaparib-resistant LN-OlapR cells, castration-resistant prostate cancer (CSPC)/Olaparib-sensitive C4-2B cells, and castration-resistant prostate cancer (CSPC)/Olaparib-resistant 2B-OlapR cells.
