Development of Pectoralis major has been investigated through gene expression analysis in comparing animals receiving a restricted diet in P and Ca (NC), a normal diet with sufficient level of P and Ca (PC), and a restricted diet supplemented with phytase (Phy1000).

View SamplesMost individuals with cystic fibrosis (CF) carry one or two mutations that result in a maturation defect of the full-length CFTR protein. The deltaF508 mutation results in a mutant protein that is degraded by the proteasome instead of progressing to the apical membrane where it functions as a cyclic AMP-regulated chloride channel. 4 phenylbutyrate modulates heat shock protein expression and promotes trafficking of deltaF508 thus permitting maturation and membrane insertion. The goal of this study was to gain insight into the genetic mechanism of PBA action through a large-scale analysis of gene expression. The Affymetrix genome spanning U133 microarray set was used to compare mRNA expression in untreated IB3-1 cell line cultures with cultures treated with 1mM 4-phenylbuyterate for 12 and 24 hr. IB3-1 deltaF508/W1282X) bronchial epithelial cells were cultured in T75 flasks with gentamicin-free LHC-8 medium. Cells were fed with 10 ml of media every 2 to 3 days. After reaching 80% confluence cells were treated with 1 mM PBA. A T75 flask of confluent IB3-1 cells was rinsed twice with ice cold Hanks buffer then scraped into 3ml of ice cold TRIzol (Gibco BRL) then rinsed with 3 ml ice cold TRIzol and the mRNA was isolated according to the TRIzol protocol. A total of 5 control cultures, 3 cultures with 12 hr BPA application and 3 cultures with 24 hr PBA application were processed

View SamplesDent disease has multiple defects attributed to proximal tubule malfunction including low molecular weight proteinuria, aminoaciduria, phosphaturia and glycosuria. In order to understand the changes in kidney function of the Clc5 transporter gene knockout mouse model of Dent disease, we examined gene expression profiles from proximal tubules of mouse kidneys.

View SamplesAberrant TGFbeta signalling is a hallmark of epithelial derived tumours. Signalling patterns can depend on the membrane trafficking and internalization of the TGFbeta receptors. Protein kinase C (PKC), particularly the atypical PKC isoforms, alter the trafficking of TGFbeta receptors and can alter TGFbeta induced gene expression.
aPKC alters the TGFβ response in NSCLC cells through both Smad-dependent and Smad-independent pathways.

View SamplesPrimary Myelofibrosis (PMF) is a myeloproliferative neoplasm characterized by hyperplastic megakaryopoiesis and myelofibrosis. Through a gene expression profile (GEP) study we recently highlighted the upregulationof miR-34a-5p in PMF versus healthy donor (HD) CD34+ hematopoietic progenitor cells (HPCs). To shed some light into the role of miR-34a-5p in PMF pathogenesis, here we unravelled the effects of the overexpression of miR-34a-5p in HPCs forcing its expression in HPCs.

View SamplesComparison of mRNA expression profiles of LT-HSCs with or without mutations in JAK2 and Ezh2 by RNA sequencing. LT-HSC mRNA was extracted from six different transgenic mice (SclCre, SclCre;Ezh2+/-, SclCre;Ezh2-/-, SclCre; JAK2V617F, SclCre; JAK2V617F;Ezh2+/-, SclCre; JAK2V617F;Ezh2-/-) 10 weeks after tamoxifen injection. Our study represents the first detailed analysis of mRNA expression profile of LT-HSC with or without mutations in JAK2 and Ezh2 , with biologic replicates, generated by RNA-seq technology. Our results revealed that mRNA expression profile of LT-HSC with different genotype showed specific gene expression patterns, which allows to do biological comprehensive and quantitative analysis for hematopoiesis. Overall design: LT-HSCs mRNA profiles six different transgenic mice (SclCre, SclCre;Ezh2+/-, SclCre;Ezh2-/-, SclCre; JAK2V617F, SclCre; JAK2V617F;Ezh2+/-, SclCre; JAK2V617F;Ezh2-/-) were generated by deep sequencing.

View SamplesAs recently reported by our group, we performed miRNA and gene expression profiling of CD34+ hematopoietic stem/progenitor cells (HSPCs) isolated from 42 PMF patient samples compared with 31 healthy controls. Integrative analysis of these profiles by means of Ingenuity Pathway Analysis (IPA) allowed the identification of several aberrantly regulated miRNA-mRNA target pairs organized in interaction networks. In particular, our results highlighted the up-regulation of miR-494-3p in CD34+ cells from PMF patients (Norfo R et al, Blood, 2014). Interestingly, among the most upregulated miRNAs, miR-494-3p emerges as being associated to the highest number of downregulated target mRNAs. In order to understand the biological role of miR-494-3p during the hematopoietic commitment and differentiation, we overexpressed this miRNA in cord blood (CB) derived-CD34+ cells. Cells were electroporated with either miR-494-3p miRNA mimic (mimic miR-494) or a negative control mimic (mimic Neg CTR). qRT-PCR confirmed miR-494-3p overexpression 24h and 4 days after transfection (RQ SEM, 512.60 137.37, p<.01, and 20.63 3.03, p<.01, respectively).
