Description
We report the in vivo androgen receptor (AR) binding sites in murine prostate, epididymis and kidney in response to physiological androgen testosterone using ChIP-sequencing and gene expression profiling by microarray. From AR cistrome analysis, we identified tissue-specific collaborating factors i.e. FoxA1 in prostate, Hnf4a in kidney and AP2a in epididymis and validated by ChIP-seq. The ChIP experiments have been performed using antibodies specific to AR, FoxA1, Hnf4a, AP-2a and IgG non-specific antibody as a negative control.

- Illumina MouseWG-6 v2.0 expression beadchip
Description
We report that the phytoestrogen genistein acts as a tissue-specific androgen receptor modulator in mouse using a novel androgen reporter mouse line and gene expression profiling. Genistein is a partial androgen agonist/antagonist in prostate, brain, and testis but not in skeletal muscle or lung. Gene expression profiling has been done from prostates of intact and castrated male mice treated with genistein or vehicle. Gene expression profiling was also done from prostates of estradiol-treated intact male mice.

Description
We report the androgen receptor recruitment to the chromatin of androgen responsive prostate cancer cell lines, LNCaP-1F5 and VCaP in response to physiological androgen 5a-dihydrotestosterone (DHT) using ChIP-sequencing. We compare the AR recruitment by DHT to that by partial agonist/antagonist cyproterone acetate and mifepristone (RU486) in LNCaP-1F5 cells. We also report the role of glucocorticoid receptor recruitment in presence of dexamethasone (Dex) in androgen responsive prostate cancer cells. The AR and GR cistrome analysis is subsequently compared with gene expression data and RNA Pol II analysis. The ChIP-seq has been performed using AR, GR, RNA Pol II antibodies.

Description
Hepatic lipid accumulation is an important complication of obesity linked to risk for type 2 diabetes. To identify novel transcriptional changes in human liver which could contribute to hepatic lipid accumulation and associated insulin resistance and type 2 diabetes (DM2), we evaluated gene expression and gene set enrichment in surgical liver biopsies from 13 obese (9 with DM2) and 5 control subjects, obtained in the fasting state at the time of elective abdominal surgery for obesity or cholecystectomy. RNA was isolated for cRNA preparation and hybridized to Affymetrix U133A microarrays.

Description
The role of Eph/ephrin signaling in numerous biological processes has been established. However, Eph/ephrin signaling has been shown to have complex role in tumor progression. The role of EphB2 receptor in the progression of cutaneous squamous cell carcinoma (cSCC) has not been studied before.

Description
Alternative mRNA splicing provides transcript diversity and has been proposed to contribute to several human diseases. Here, we demonstrate that expression of genes regulating RNA processing is decreased in both liver and skeletal muscle of obese humans. To determine the metabolic impact of reduced splicing factor expression, we further evaluated the splicing factor, SFRS10, identified as down-regulated in obese human liver and skeletal muscle and in high fat fed rodents. siRNA-mediated reductions in SFRS10 expression induced lipogenesis and lipid accumulation in cultured hepatocytes. Moreover, SFRS10 heterozygous mice have both increased hepatic lipogenic gene expression and hypertriglyceridemia. We also demonstrate that LPIN1, a key regulator of lipid metabolism, is a splicing target of SFRS10, with reduced SFRS10 levels favoring the lipogenic isoform of LPIN1. Importantly, LPIN1-specific siRNA abolished the lipogenic effects of decreased SFRS10 expression. Together, our results indicate reduced expression of SFRS10 alters LPIN1 splicing and induces lipogenesis, demonstrating that reduced splicing factor expression observed in human tissues may contribute to metabolic phenotypes associated with human obesity.
Publication Title
Expression of the splicing factor gene SFRS10 is reduced in human obesity and contributes to enhanced lipogenesis.
