Project description:Transcription profiling by array of human benign prostate, primary and metastatic prostate cancer samples to reveal signatures of metastatic progression
Project description:Here we used Illumina NGS for high-throughput profiling of the DNA methylome in seven human benign prostate tissues, seven human primary prostate cancer and six human castration resistant prostate cancer patient samples. These data were used to profile the CpG cytosine methylation pattern at single base resolution in each sample and to determine differentially methylated cytosines and regions among samples. Enhanced Reduced Representation Bisulfite Sequencing (ERRBS, MspI,150M-bM-^@M-^S400 bp size fractions) of 20 human prostate tissues (benign prostate tissues, localized and metastatic prostate cancer)
Project description:Bulk RNA sequencing of peripheral blood neutrophils from prostate cancer at different stages of disease progression, including localized disease, hormone-sensitive- and castration-resistant metastatic prostate cancer
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:We compared 22 primary Pca (hormone-dependent) versus 29 metastatic Pca (CRPC). The expression of genes related to cell cycle, proliferation, DNA synthesis, and androgen metablism are significantly increased in CRPC group. The expression of AR-stimulated genes were partially reactivated. TMPRSS2-ERG fusion status was determined for the samples by PCR. The expression of ERG was highly increased in fusion positive versus negative. 120 snap-frozen CT-guided bone marrow biopsies from patients with castration-resistant prostate cancer were collected as a source of material. 29 independent biopsies containing mostly tumor were identified as CRPC group through carefully microscopical examination. 4 samples containing no tumor were identified as normal bone marrow group. Primary tumor was isolated by LCM from frozen biopsies of hormone-naive patients. 22 samples were selected as primary PCa group.
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.
