Cooperativity and Equilibrium with FOXA1 Define Androgen Receptor Transcriptional Program [array]

Project description:Previous studies have shown that FOXA1 defines prostatic AR binding events, the underlying mechanisms of which, however, are incompletely understood. To test whether ectopic AR and FOXA1 can activate AR target genes, we performed adenoviral of LacZ, AR, FOXA1 or AR+FOXA1 proteins in DU145 cells, followed by microarray analysis of these cells.

Androgen receptor-independent function of FoxA1 in prostate cancer metastasis

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 engineered LNCaP cells with FoxA1 knockdown using shRNA or siRNA, 22RV1 cells with stable FoxA1 knockdown and PC3M cells with FoxA1 stable overexpression. We performed microarray analysis of these cells. We performed microarray analysis on LNCaP cells with FoxA1 knockdown using shRNA or siRNA, 22RV1 cells with stable FoxA1 knockdown and PC3M cells with FoxA1 stable overexpression

Dual Role of FoxA1 in Androgen Receptor Binding to Chromatin, Androgen Signaling and Prostate Cancer [ChIP_seq, DHS_seq]

Project description:We report the dual role of FoxA1 in androgen receptor recruitment to the chromatin of androgen responsive prostate cancer cell line LNCaP-1F5 using ChIP-sequencing. Depletion of FoxA1 reprograms both androgen and glucocorticoid receptor recruitment and subsequent gene expression. The ChIP-seq has been performed using AR, FoxA1, GR, H3K4me2 antibodies. We have also mapped the DNaseI-hypersensitive sites (DHS) using deep sequencing. Examination of AR, FoxA1, GR, H3K4me2 binding sites and DHS sites in parental and FoxA1 depleted LNCaP-1F5 cells.
