Project description:This SuperSeries is composed of the following subset Series: GSE25068: PcG/TrxG profiling of differentially aged adipose-derived mesenchymal stem cells GSE25069: Whole-genome microarray of long-term cultured adipose derived mesenchymal stem cells from differentially-aged mice GSE25679: microRNA profiling of mesenchymal stem cells from adipose tissue of differentially aged mice Refer to individual Series
Project description:The microarray reported here is part of a study aimed to investigate whether the gene expression of Polycomb, Trithorax and interacting molecule might be related to differet states of differentialtive potential. In particular, the dataset herein is a whole-genome microarray profiling of long-term (20th passage) cultured mesenchymal stem cells isolated from the inguinal fat pad of mice of differentially aged mice. Whole genome transcriptional profile of mesenchymal stem cells isolated from FVB mice of 1 (n=3) or 12 (n=3) months of age.
Project description:The microarray reported here is part of a study aimed to investigate whether the gene expression profile of Polycomb, Trithorax and interacting molecules (collectively referred to PcG/TrxG genes) might be related to different states of differentiative potential. In particular , this microarray profiles the expression of PcG/TrxG genes in adipose-derived mesenchymal stem cells isolated from the inguinal fat depot of mice of different age. MSC have been isolated from the inguinal fat pad of FVB mice aged 1, 3, 6, 12 or 24 months.
Project description:The aim of this study was to explore the gene expression and metabolites among multisite adipose-derived mesenchymal stem cells, and investigate the metabolic pathway of multisite adipose-derived mesenchymal stem cells using a multi-omics analysis. Subcutaneous adipose-derived mesenchymal stem cells (SASCs), perirenal adipose-derived mesenchymal stem cells (PASCs), and epididymal adipose-derived mesenchymal stem cells (EASCs) were isolated from Sprague Dawley rats. RNA and metabolites were extracted and sequenced using transcriptomics and metabolomics analyses, respectively. There were 720 differentially expressed genes (DEGs) in EASCs and 688 DEGs in PASCs compared with SASCs; there were 166 unique DEGs in EASCs, 134 unique DEGs in PASCs, and 554 common DEGs between EASCs and PASCs. Furthermore, there were 220 differential metabolites in EASCs, 249 differential metabolites in PASCs, 83 unique differential metabolites in EASCs, 112 unique differential metabolites in PASCs, and 137 common differential metabolites between EASCs and PASCs. The transcriptomics and metabolomics analyses identified four hub genes, one in EASCs and three in PASCs. There are functional differences among multisite adipose-derived mesenchymal stem cells that may be related to the hub genes Atac2, Rrm1, Rrm2, and Gla. The relevant signaling pathways are the Ras signaling pathway, HIF-1 signaling pathway, and the p53 signaling pathway.
Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility. Gene expression was measured in whole testis from males aged 62-86 days. Samples include 190 first generation lab-bred male offspring of wild-caught mice from the Mus musculus musculus - M. m. domesticus hybrid zone.
