Project description:Aristolochic acid nephropathy (AAN) is characterised by rapidly progressive tubulointerstitial nephritis culminating in end stage renal failure and urothelial malignancy. microRNAs (miRs) are small endogenous post-transcriptional regulators of gene expression implicated in numerous physiological and pathological processes. We aimed to characterise the mechanism of AA induced cell cycle arrest and its regulation by miRs. The microarray experiment was performed to identify differentially regulated microRNAs in human proximal tubulal epithelial cells treated with aristolochic acid (AA). Analysis or differential miR expression in human proximal tubular epithelial cell line (HK-2) treated with 5ug/ml aristolochic acid, control (n=3) vs aristolochic acid (n=3)

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:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
