Expression data from H295R cells in basal conditions/overexpressing SF-1

Project description:SF-1 is a nuclear receptor transcription factor playing a key role in adrenogonadal development and in adrenocortical tumorigenesis when overexpressed. We studied gene expression profiles using Affymetrix microarrays in the H295R/TR SF-1 adrenocortical cancer cell line, where SF-1 expression can be increased in a doxycycline-dependent manner (Mol. Endocrinol. 21: 2968–2987, 2007) H295R/TR SF-1 cells were cultured either in basal conditions or with doxycycline (Dox) added to the culture medium for 72 hours. RNA was extracted and hybridized to HG-U133 Plus 2.0 Affymetrix microarrays.

Genome-wide SF-1 (NR5A1) binding sites in NCI-H295R cells

Project description:The nuclear receptor steroidogenic factor-1 (SF-1, NR5A1) is a key regulator of adrenal and gonadal biology. We aimed to identify a novel subset of SF-1 target genes in the adrenal by performing ChIP-on-chip in NCI-H295R human adrenocortical cells using promoter tiling arrays. Analysis of ChIP-on-chip experiments with CisGenome identified 738 SF-1-binding regions that met criteria of an MA score more than 3.5 mean ± S.D. and a false discovery rate of <5%. Subsequent analysis focused on those regions that were located between 10 kb upstream and 3 kb downstream of the TSS of known genes, in keeping with the design of the Human Promoter 1.0R arrays. Using this approach, binding regions were annotated to 445 gene loci. The supplementary bed file contains all 946 SF-1 binding sites identified by analysis with CisGenome using standard settings (MA>3.0)

Identification of genes regulated by overexpressed SF-1 in human adrenocortical cells

Project description:SF-1, a transcription factor belonging to the nuclear receptor superfamily, has a pivotal role for adrenogonadal development in humans and mice. A constant feature of childhood adrenocortical tumors (ACT) is SF-1 amplification and overexpression. Using an inducible cellular system, here we show that SF-1 overexpression increases human adrenocortical cell proliferation through opposing effects on cell cycle and apoptosis. SF-1 overexpression also selectively modulates steroidogenesis, reducing cortisol and aldosterone secretion. We identified a novel pro-apoptotic factor for adrenocortical cells, NOV/CCN3, whose levels are significantly reduced by SF-1 overexpression in human adrenocortical cells and are also reduced in primary adrenal tumors. Moreover, Sf-1 overexpression triggers adrenocortical hyperplasia and tumor formation in mice. These tumors express gonadal markers and activated Stat3. Our studies reveal the critical role of SF-1 gene dosage for adrenocortical tumorigenesis and constitute a rationale for the development of drugs targeting SF-1 transcriptional activity for ACT therapy. Keywords: differential expression, transcription factor Gene expression profiles were analyzed in two different H295R TR/SF-1 WT clones overexpressing SF-1 in a tetracycline-regulated fashion cultured in basal conditions or after three days of doxycycline treatment. For each condition, two biological replicates were examined.
