Gene expression in livers of adult male mice subjected to continuous GH infusion using Alzet osmotic minipumps for 1, 4 or 7 days was assayed by RNA-seq, as part of a study of growth hormone regulation of hepatic lincRNAs (PMID:26459762) and protein-coding genes (PMID:28694329). Overall design: RNA isolated from livers obtained from untreated male mice, or from male mice subjected to continuous GH tratment for 1, 4 or 7 days were prepared and used for unstranded RNA-seq.

View SamplesrRNA-depleted RNA isolated from livers of intact male and female mice and from male mice treated with a continuous infusion of growth hormone for either 10 hr or 1 days was analyzed by RNA-seq Overall design: Liver RNA was isolated from 8 week old male mice treated with a continuous GH infusion (cGH) for either 10 hours or 1 day. Sham pump males served as a control. RNA-seq data are compared to untreated adult females to identify genes that show sex differences in liver expression and also respond to cGH. RNA samples were pooled to make 3 biological replicates per condition comprised of 2-4 individuals each.

View SamplesWe investigated the effects of a single pulse of growth hormone on the transcriptional activation of STAT5 target genes in hypophysectomized male mouse liver. This GEO series is part of a larger study, where we investigated the impact of a single pulse of GH given to hypophysectomized mice on local liver chromatin accessibility [DNase hypersensitive site analysis], transcription rates [hnRNA analysis], and gene expression [quantitative PCR and RNA-Seq] determined 30, 90 or 240 min later. The STAT5-dependent but sex-independent early GH response genes Igf1 and Cish showed rapid, GH pulse-induced increases in chromatin accessibility and gene transcription, reversing the effects of hypophysectomy. Rapid increases in liver chromatin accessibility and transcriptional activity were also induced in hypophysectomized male mice for some (Ces2b, Ugt2b38) but not for other liver STAT5-dependent male-biased genes (Cyp7b1). Moreover, in pituitary-intact male mice, Igf1, Cish, Ces2b and Ugt2b38 all showed remarkable cycles of chromatin opening and closing, and associated cycles of induced gene transcription, which closely followed each endogenous pulse of liver STAT5 activity. Thus, the endogenous rhythms of male plasma GH pulsation dynamically open and then close liver chromatin at discrete, localized regulatory sites in temporal association with transcriptional activation of Igf1, Cish and a subset of STAT5-dependent male-biased genes. Overall design: Liver RNA was isolated from hypophysectomized male mice that were untreated, or were treated with a single pulse of GH and euthanized 30, 90 or 240 minutes later. 8 Individual RNA samples were pooled to make 2 biological replicates per condition for RNA-seq analysis.

View SamplesWe integrated three transplant rejection microarray studies examining gene expression in samples from pediatric renal, adult renal, and adult heart transplants. We performed one study ourselves and retrieved two others from the NCBI Gene Expression Omnibus (GEO)(GSE4470 and GSE1563). We identified 45 genes that were upregulated in common in acute rejection. Half were involved in one immune-related pathway. Among ten proteins we tested by serum ELISA, three successfully distinguished acute rejection from stable transplants. These were CXCL9, PECAM1, and CD44, with areas under the receiver operating characteristic curves of 0.844, 0.802, and 0.738, respectively. Immunohistochemistry showed that the PECAM1 protein was increased in acute rejection in renal, liver and heart transplants versus normal tissues. Our results show that integrating publicly-available gene expression data sets is a fast, powerful, and cost-effective way to identify serum-detectable diagnostic biomarkers.

View SamplesFollicular Lymphomas are blood tumors growing as spheres in patients. Before this study, there was no experimental model mimicking the 3D organization of these in vivo tumors. We develop such a model, called MALC, and observed a progressive enrichment in quiescent cells in these with time of culture; these cells were sorted, as their cycling counterparts, and their transcriptomes were compared. We used microarrays to detail the differential global gene expression profile between quiescent and cycling cells isolated from MALC.
