Zinc finger and BTB domain containing transcription repressor ZBTB7A has been recently reported as a tumor suppressor who plays important functions to prevent the progression of prostate cancer. However, the chromatin activity of ZBTB7A in prostate cancer cells remain unclear. In order to identify the cistrome and transcriptome of ZBTB7A, we performed ZBTB7A ChIP-seq in VCaP cells and RNA-seq in VCaP cells transfected with siRNA targeting ZBTB7A or non-targeting control, respectively (cells were grown in full serum). By using combined ChIP-seq and RNA-seq analyses in VCaP cells, we have precisely mapped the ZBTB7A binding sites and identified a subset of genes that are directly repressed by ZBTB7A. To study the chromatin interaction of ZBTB7A with androgen receptor (AR), we also performed ChIP-seq of ZBTB7A in VCaP cells stimulated with 10 nM DHT for 4 hours versus vehicle control (cells were hormone-depleted prior to DHT stimulation). Our results show that ZBTB7A binding is increased by androgen at AR and ZBTB7A overlapping sites. SOURCE: Changmeng Cai (changmeng.cai@umb.edu) - University of Massachusetts Boston
