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

Project description: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. castrated mice (androgen-dependent vs. castration-resistant). We identify an 11-gene Src-induced signature found only in CRPC in response to DHT, and moreover, the differentail expression of a subset (DPP4, BCAT1, CNTNAP4, CDH3) correlates with earlier PC metastasis onset and poorer survival.

Project description:Docetaxel-based chemotherapy is the standard first-line therapy in metastatic castration-resistant prostate cancer. However, most patients eventually develop resistance to this treatment. The aim of the study was to identify key molecular genes and networks associated with docetaxel resistance in 2 models of docetaxel-resistant castration-resistant prostate cancer cell lines.
