KMT2D promotes castration-resistant prostate cancer progerssion by reactivating AR via FOXA1 [ATAC-Seq]

Project description:Histone methyltransferase KMT2D is epigenetic modifier mediates histone H3 lysine 4 methylation (H3K4me) with distinct roles across different cancer types. We previous found that KMT2D promotes growth and metastasis in Androgen receptor (AR)-negative prostate cancer (PCa). However, the functions of KMT2D and the relationship with AR in AR-positive prostate cancer remain unclear. Here, we showed that inhibition of KMT2D reduced AR-positive PCa cell survival and the sensitivity to dihydrotestosterone, a ligand for AR. RNA-Seq analysis revealed that KMT2D suppression significantly attenuated AR signaling pathway. Through multiple-omics analysis, we revealed that KMT2D recruits pioneering transcription factor Forkhead box A1 (FOXA1) to AR-specific enhancer sites, induces open chromatin conformations, and facilitates AR binding at enhancers to activate downstream gene expression, ultimately leading to AR reactivation. KMT2D knockout by CRISPR/Cas9 reduced CRPC tumor growth and AR signaling pathway activation in vivo. KMT2D-FOXA1-AR axis also mediates ketone metabolic reprogramming by regulating the expression of the key enzyme HMGCS2 to promote PCa progression. Finally, targeting UTX, a member of complex of proteins associated with SET1 (COMPASS) in which KMT2D involved, suppressed PCa cell survival and tumor growth by impairing H3K4me1 modification via KMT2D. These findings demonstrate the oncogenic role of KMT2D in PCa, suggesting that blocking COMPASS to inhibition KMT2D’s function may be a promising strategy to treat PCa.

Tumor-Specific Retrogene NANOGP8 Reprograms Prostate Cancer Cells to Castration Resistance by Engaging the FOXA1/AR Signaling Axis and MYC [RNA-seq]

Project description:Targeted disruption of the embryonic stem cell (ESC) self-renewal and pluripotency factor NANOG diminishes cancer cell clonogenic growth in vitro and tumor development in vivo. NANOG has also been shown to augment CSC properties and propel the emergence of castration-resistance prostate cancer (CRPC) phenotypes. Here, we investigate the molecular mechanisms underlying NANOG-mediated oncogenesis and prostate cancer progression to androgen independence. ChIP-Seq analysis of LNCaP prostate cancer cells overexpressing doxycycline-inducible NANOG (either NANOG1 or NANOGP8 vs pLVX control) reveal that NANOG coordinately occupies regions of chromatin regulated by AR signaling steroid-receptor complex proteins AR, FOXA1 and NKX3.1. Taken together with the NANOG-induced changes in the prostate cancer transcriptome (RNA-Seq), NANOG appears to reprogram prostate cancer cells to castration resistance by converging on steroid-hormone receptor signaling.

Pioneer factor FOXA1 defines GATA2- and AR-mediated transcriptional program in prostate cancer [ChIP-Seq]

Project description:AR is tightly regulated by many transcriptional cofactors, including key pioneer factor such as FOXA1 and GATA2. While FOXA1 was recently shown to be able to redistribute AR across the genome, how GATA2 regulates AR cistrome has not been carefully investigated. Here, we report that, unlike FOXA1, GATA2 is unable to reprogram AR, but instead it enhances AR program by inducing AR expression and augmenting AR co-occupancy, thereby acting as a pure AR coactivator, rather than a pioneer factor. On the other hand, AR co-occupancy enhances both GATA2 and FOXA1 binding on the chromatin, forming a positive feedback loop. Importantly, we found that FOXA1 is also capable of reprogramming GATA2 by recruiting GATA2 from GATA motif to FKHD-containing regions, being analogous to its pioneering effect on AR signaling. By contrast, GATA2 simply acts as a co-activator of FOXA1 with a lack of pioneering ability. ChIP_Seq examination of AR, FoxA1 and GATA2 binding sites in LNCaP and DU145 cells
