Project description:Screen mRNAs specifically regulated by mTORC1 in calvarial osteoblasts from mice

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:Recent work using mouse models has revealed that mTORC2, which unlike mTORC1 is not acutely sensitive to rapamycin, plays a key role in the regulation of organismal physiology. The substrates and pathways regulated by mTORC2 are at present relatively unknown Using a mouse model with a targeted deletion of hepatic RICTOR, we investigated the loss of mTORC2 on the murine liver transcriptome Rictor floxed (RKO) and control mice (n=4 per group) were fasted overnight, refed for 3 hr, then sacrificed. Livers were removed, rinsed in PBS, and flash frozen in liquid nitrogen. RNA was extracted and hybridized to Affymetrix Genechip Mouse Gene 1.0 ST arrays

Results tested and confirmed by northern blotting.

Project description:To screen mRNAs specifically regulated by mTORC1, a global mRNA expression profile in calvarial osteoblasts (OBs) from mice with or without OB-specific Tsc1 knockout was developed using microarray. Wild type (WT) or OB-specific Tsc1 knockout (KO) mice were sacrificed, with calvarial osteoblasts harvested and subjected to total RNA extraction.
