Project description:Prostate cell lines from diverse backgrounds are important to addressing disparities in prostate cancer (PCa) incidence and mortality rates among Black men. ACRJ-PC28 was developed from a transrectal needle biopsy and established via inactivation of the CDKN2A locus and simultaneous expression of human telomerase. Characterization assays included growth curve analysis, immunoblots, IHC, 3D cultures, immunofluorescence imaging, confocal microscopy, flow cytometry, WGS and, RNA-Seq. RNA-Seq confirmed the expression of prostate specific genes alpha-methylacyl-CoA racemase (AMACR) and NKX3.1 and Neuroendocrine specific markers, synaptophysin (SYP) and enolase 2 (ENO2) and IHC confirmed the presence of AMACR. WGS confirms the absence of exonic mutations and the presence of intronic variants that appear to not affect function of AR, p53 and pRB. RNA-Seq data revealed numerous TP53 and RB1 mRNA splice variants and the lack of AR mRNA expression. The novel cell line described here should advance research addressing the disparity in prostate cancer among Black men.
