Project description:Transcriptional regulator REST plays a key role in repressing neuronal specific genes in prostate cancer and other non-neuronal tissues. Moreover, loss of REST is observed in neuroendocrine prostate tumors. Here, we use ChIP-seq analysis to study genome–wide REST occupied regions in the prostate cancer cell line, LNCaP. REST occupied regions were then correlated to gene expression changes occurring between prostate adenocarcinoma and neuroendocrine prostate tumors in vivo.
Project description:FoxA1 has been shown critical for prostate development and prostate-specific gene expression regulation. In addition to its well-established role as an AR pioneering factor,several studies have recently revealed significant AR binding events in prostate cancer cells with FoxA1 knockdown. Furthermore, the role of FoxA1 itself in prostate cancer has not been carefully examined. Thus, it is important to understand the role of FoxA1 in prostate cancer and how it interacts with AR signaling. To address these questions, we generated LNCaP cells with stable FoxA1 knockdown. We performed AR/FoxA1 ChIP-seq and microarray analysis of these cells. ChIP_Seq examination of AR and FoxA1 binding sites in LNCaP shCtrl and shFoxA1 cells
Project description:Prostate cancer is the most common cancer in men and cardiac glycosides inhibit prostate cancer cell proliferation. In order to investigate the mechanism by which cardiac glycosides inhibit prostate cancer cells, we observed genome-wide RNA expression in prostate cancer LNCaP-abl cells, hormone resistant cells, after the cardiac glycoside treatment using RNA-Seq. In addition, we profiled LNCaP-abl cells after androgen receptor (AR) knockdown to observe whether cardiac glycoside effect on RNA expression is similar to that of AR knockdown. Observation of three cardioglycosides, Digoxin, Peruvoside and Strophanthidin, and AR knockdown regulated RNA expression in LNCaP-abl with RNA-Seq (each triplicates)
