Project description:We discovered that mitochondrial uncouplers represented by nitazoxanide and its active metabolite tizoxanide inhibited prostate cancer growth. This RNA-seq study aims to elucidate the mechanism by which mitochondrial uncouplers inhibit prostate cancer growth. The results indicate that mitochondrial uncouplers predominantly downregulated E2F1 target genes and thus likely inhibited prostate cancer growth through impeding E2F1-mediated transcription.
Project description:Prostate cancer is the most common cancer in men and androgen receptor (AR) downstream signalings promote prostate cancer cell proliferation. To investigate the AR signaling, we performed directional RNA sequence analysis in AR positive prostate cancer cell line, LNCaP and VCaP. Using Noncode and GENCODE data sets. We identified androgen-regulated long non-coding RNAs (lncRNAs) in prostate cancer cells. Directional RNA sequence analysis of androgen-regulated lncRNAs in prostate cancer cells

Project description:Transcription factor Stat5 is constitutively active in human prostate cancer but not in normal prostate epithelium. Stat5 activation is associated with prostate cancer lesions of high histological grades, and is present in the majority of castration-resistant recurrent human prostate cancers. The molecular mechnisms underlying constitutive activation of Stat5 in primary and recurrent human prostate cancer are currently unclear. We used microarrays to detail gene expression regulated by Stat5 in human prostate cancer cells.

The molecular mechnisms underlying constitutive activation of Stat5 in primary and recurrent human prostate cancer are currently unclear. We used microarrays to detail gene expression regulated by Stat5 in human prostate cancer cells. DU145 human prostate cancer cells were transfected with Stat5a/b siRNA or scramble siRNA as control. After 48 h, the cells were harvested and total RNA was prepared for Affymetrix microarrays.
