Project description:Here we report the gene expression profile of in vitro cultured human endometrial stromal cells treated with siRNA targeting FOXO1 piror to eutherian differentiation media exposure. The eutherian differentiation media contains cyclic AMP (cAMP) analogue 8-Br-cAMP and the progesterone (P4) analogue medroxyprogesterone acetate (MPA).

Project description:Asthma is a chronic inflammatory airway disease characterized by airway inflammation and remodeling. The role of 15-oxo-5Z,8Z,11Z,13E-eicosatetraenoic acid (15-oxoETE), a 15-HETE metabolite catalyzed by 15-prostaglandin dehydrogenase (15-PGDH), has been relatively unexplored in asthma. In this study, we used RNA-seq to explore the effect of 15-KETE on the transcriptome of airway epithelial cells, aiming to identify its potential downstream targets and mechanisms of action.

Project description:We have sequenced miRNA libraries from human embryonic, neural and foetal mesenchymal stem cells. We report that the majority of miRNA genes encode mature isomers that vary in size by one or more bases at the 3’ and/or 5’ end of the miRNA. Northern blotting for individual miRNAs showed that the proportions of isomiRs expressed by a single miRNA gene often differ between cell and tissue types. IsomiRs were readily co-immunoprecipitated with Argonaute proteins in vivo and were active in luciferase assays, indicating that they are functional. Bioinformatics analysis predicts substantial differences in targeting between miRNAs with minor 5’ differences and in support of this we report that a 5’ isomiR-9-1 gained the ability to inhibit the expression of DNMT3B and NCAM2 but lost the ability to inhibit CDH1 in vitro. This result was confirmed by the use of isomiR-specific sponges. Our analysis of the miRGator database indicates that a small percentage of human miRNA genes express isomiRs as the dominant transcript in certain cell types and analysis of miRBase shows that 5’ isomiRs have replaced canonical miRNAs many times during evolution. This strongly indicates that isomiRs are of functional importance and have contributed to the evolution of miRNA genes

Project description:The human uterus undergoes profound physiological tissue remodelling during pregnancy. In the myometrium, altered gene expression must underlie these extensive molecular and structural changes. The purpose of this study was to compare expression profiles of pregnant and non-pregnant myometrium, in order to identify genes that participate in this process. mRNA from 14 non-pregnant and four pregnant human myometrial samples were analysed using a human UniGEM V microarray with 7075 cDNA elements. A total of 602 transcripts from the microarray were up-regulated >=2.0-fold in pregnant myometrium, with 37 transcripts up-regulated >=4.0-fold. In contrast, eight transcripts were down-regulated >=2.0-fold in pregnancy. To ensure accurate representation of differential gene expression, Northern blot analyses using total RNA from 16 samples of non-pregnant and pregnant myometrium were used to examine mRNA levels for four of the genes that were differentially expressed by microarray analysis, namely plasminogen activator inhibitor type 1 (PAI-1), milk fat globule-EGF factor 8 protein (MFGE8), secreted frizzled-related protein 4 (sFRP4) and estrogen receptor {alpha} (ER{alpha}). On the microarray these transcripts were up-regulated 7.5-fold for PAI-1 and 4.9-fold for MFGE8 in pregnant myometrium, and down-regulated 3.7-fold for sFRP4 and 2.9-fold for ER{alpha} in pregnancy. Northern blot analyses confirmed these changes. Our findings suggest that microarray technology is a useful tool for examining global changes in gene expression that occur as the myometrium differentiates from non-pregnant to pregnant status. Defining these changes provides new insight into the structural and functional adaptations of human myometrium during pregnancy. Keywords: other
