Project description:Analysis of gene expression profile in Ras-induced senescent human diploid fibroblasts with or without depletion of fzr1/cdh1. Results provide insight into the effect on fzr1/cdh1 on the regulation of senescence-associated gene expression in human diploid fibroblasts.
Project description:Analysis of gene expression profile in Ras-induced senescent human diploid fibroblasts with or without depletion of fzr1/cdh1. Results provide insight into the effect on fzr1/cdh1 on the regulation of senescence-associated gene expression in human diploid fibroblasts. IMR-90-ER:Ras cells were cultured for 6 days with or without 4-hydroxytamoxifen (OHT) and were subsequently subjected to transfection with siRNA oligos against fzr1/cdh1 or control for three times (at 2 day intervals). Total RNA was isolated using Trizol reagent and were analyzed using the human 3D-Gene DNA chip (Toray) which that contains 25000 genes. The genome wide transcriptional response of proliferating cells (IMR si control2) and fzr1/cdh1 depleted senescent cells (IMR+OHT si cdh1) were compared to that of senescent cells (IMR+OHT si control).
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.

Goal was to determine the effects of hypoxia on global MSCs gene expression. Two-condition experiment, Normoxic MSCs vs. Hypoxic MSCs.
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.
