Project description:Naked mole-rat skin fibroblasts (NSF) produces vHMM-HA. Although NSF-HA has been shown to suppress NSF transformation, it is still unclear if exceptional polymer length of vHMM-HA is important for its functions. Here, we compared the effect of intact control NSF-HA (cNSF-HA) ) on the transcriptome of CD44-overexpressing IMR90 cells.
Project description:The role of CD44 in naked-mole rats (NMR) oligodendrocyte progenitor cells (OPCs) were evaluated by comparing the transcriptome of control and CD44-knockdown NMR OPCs.
Project description:To identify the sequences responsible for recruitment of Glucocorticoid receptor (GR) to individual loci, we performed ChIP-seq and ChIP-exo that combines chromatin immunoprecipitation with an exonuclease digestion step. We performed these experiments in three cell lines : IMR90 (ATTC:CCL-186), U2OS osteosarcoma cell lines, K562 (ATCC:CCL243), upon glucocorticoid treatment.
Project description:Mammalian SIRT1 is a central regulator of metabolism and aging. This project is to analyze global phosphorylation levels of mammalian SIRT1 in proliferating and senescence states using human lung fibroblast IMR90, in order to explore the post-translational regulation of SIRT1 protein upon cellular senescence and its potential roles in the regulatory mechanisms of SIRT1 homeostasis.
Project description:To identify genes that are differentially expressed between CD44+ and CD44- cells in colonospheres, we have employed whole genome microarray expression profiling as a discovery platform. Colonospheres from four colon cancer patients were sorted into CD44+ and CD44- cells using the FACS Aria II Cell Sorter, and total RNA extracted from the cells were labeled with Cy3 and used for microarray analyses with Agilent Whole Human Genome Oligo Microarrays. Gene expression in fluorescence-activated cell-sorted CD44+ and CD44- cells derived from four colon cancer patients was measured.
Project description:We hypothesized that there were genes involved in the maintenance of intestinal tolerance to commensal bacteria. These genes should meet the following criteria: expressed in intestines, upregulated in the presence of commensal bacteria and downregulated in absence of microbes. To find these genes, we collected small intestines from postnatal mice that neither affected by the bacteria nor by the food, adult mice bred in germ-free or specific pathogen-free conditions, and adult SPF mice treated with antibiotics. We therefore performed bulk RNA sequencing using these cells.
Project description:Total RNA was isolated from proliferating and senescent IMR90 cells to compare gene-expression to the changes in nucleolus-association in proliferating and senescent IMR90 cells.
Project description:To investigate the significance of CD44+ hepatocellular carcinoma (HCC) HuH7 cells, gene expression profiles of CD44-positive HuH7, CD44-negative HuH7, and human nomal hepatocyes were analyzed. Results provide the insight into the significance of CD44-positive HCC cells as the liver CSCs.
