View SamplesNuclear receptor Reverb alpha is a component of circadian rythm which could be evolved in cardioprotection strategy. We test if pharmacological modulation of these target could be suitable for cardioprotection after ischemia reperfusion injury

View SamplesIn the present study, to identify potential paracrine factor for the stromal regulation of E2-induced epithelial cell proliferation, we treated epithelial and stromal cell populations of mouse uterine primary co-culture with either oil or E2. Three independent RNA pools prepared for each population were then subjected to the Affymetrix gene chip analysis for the whole mouse genome transcripts. Our data revealed up-regulation of 119 genes and down-regulation of 28 genes in epithelial cell populations and up-regulation of 144 genes and down-regulation of 192 genes in stromal cell population.
Estrogen mediated epithelial proliferation in the uterus is directed by stromal Fgf10 and Bmp8a.

View SamplesFamilial hypertrophic cardiomyopathy (FHC) is a disease characterized by ventricular hypertrophy, fibrosis, and aberrant systolic and/or diastolic function. Our laboratories have previously developed 2 mouse models that affect cardiac performance. One transgenic mouse model encodes an FHC-associated mutation in -tropomyosin (Tm180) that displays severe cardiac hypertrophy with fibrosis and impaired physiological performance. The other model was a gene knockout of phospholamban (PLB), a regulator of calcium uptake in the sarcoplasmic reticulum of cardiomyocytes; the hearts of these mice exhibit hypercontractility with no pathological abnormalities. Previous work in our laboratories show that the hearts of mice that were genetically crossed between the Tm180 and PLB KO mice rescues the hypertrophic phenotype and improves their cardiac morphology and function.

View SamplesWe extract RNA from mouse implantation sites (IS) on D8 of pregnancy. Mice were treated with or without PRT4165, an inhibitior of PRC1. Total RNAs were analyzed by RNA sequncing. Overall design: There are four samples to be analyzed:Control group 1) "D8ISCOT-1" and 2) "D8ISCOT-2” ; PRT4165 treated groups 3) "D8ISPRT4165-1", 4)”D8ISPRT4165-2”

Gene expression signature for biliary atresia and a role for interleukin-8 in pathogenesis of experimental disease.
Specimen part, Time
View SamplesLiver biopsy samples were obtained from 64 infants with biliary atresia at the time of intraoperative cholangiogram. Liver biopsy samples were obtained from 14 age-matched infants with other causes of intrahepatic cholestasis, and from 7 deceased-donor children. GeneChip Human Gene 1.0 ST Array (Affymetrix, CA) were used to screen mRNAs whose expression was specifically regulated in the livers from patients with biliary atresia.

View SamplesNewborn Balb/c mice were injected intraperitoneally with 1.5x10^6 fluorescent-forming units (ffu) of type- A Rhesus Rotavirus (RRV) or 0.9% normal saline (NS; control) within 24 hours of birth to induce experimental model of biliary atresia. Extrahepatic bile ducts including gallbladder were microdissected en bloc at 3, 7 and 14 days after RRV or saline injections. GeneChip Mouse Gene 1.0 ST Array (Affymetrix, CA) were used to screen mRNAs whose expression was differently regulated after RRV challenge compared to normal saline controls.

View SamplesInterleukin-31 (IL-31), a T cells derived cytokine which is mainly produced by CD4+ T cells skewed towards Th2 phenotypes. It signals via a heterodimeric receptors composed of IL-31RA and OSMR that is expressed constitutively in epithelial cells and keratinocytes. IL-31 is shown to play a pathogenic role in allergic and inflammatory diseases. Transgenic mice overexpressing IL-31 have a phenotype similar to atopic dermatitis. Here, we studied the role of IL-31 in skin damage by intradermal administration of recombinant IL-31. Notably, IL-31 was sufficient to increase epidermal basal cell proliferation and thickening of the epidermal layer of skin in mice. Analysis of skin transcriptome indicates a significant increase in the transcripts involved in epidermal cell proliferation and pathological skin remodeling. Thus, our study revealed an important role of IL-31 signaling in activating transcriptional programs involved in the pathophysiology of skin diseases. Overall design: mRNA profiles of C57BL/6 mice skin injected with saline and rIL-31 (20µg) via i.d.
