Project description:to find functional relevance between SMC5/6 complex and SAGA histone acetyltransferase complex in Schizosaccharomyces pombe by chromatin immunoprecipitation of Nse4-FLAG tagged protein from gcn5, ubp8 and ada2 deletion strains and 2 control strains (WT - Nse4-FLAG, 501 - no tag).
Project description:Adult muscle stem cells show a high transcriptional and clonal heterogeneity during ageing. Whether microRNAs contribute to this diversity is not known. Here we use tissue-specific genetic deletion of microRNA (miR)-501 that is highly enriched in activated myogenic progenitor cells to address this question. Single-cell sequencing revealed a novel subpopulation of committed myogenic progenitor cells in miR-501 knockout mice that express high levels of terminal differentiation markers and inflammatory genes such as CD74. Our data show that stem cell heterogeneity in skeletal muscle during ageing is under miRNA control.
