Project description:To determine if fibroblasts could be reprogrammed to a keratinocyte phenotype p63+KLF4 or LacZ expressing retroviruses were transduced into primary human neonatal fibroblasts. Global gene expression profiling using U133 plus 2.0 arrays were used to deteremine the extent of reprogramming to a keratinocyte phenoypte upon transduction with p63+KLF4. Fibroblasts transduced with p63+KLF4 were also treated +/- high calcium to determine if treatment with calcium could induce differentiation of these cells. Microarray analysis was also performed on cells treated +/- calcium. For gene expression profiling, cultured human fibroblasts were infected with LacZ or p63+KLF4 expressing retroviruses. p63+KLF4 cells were also treated +/- calcium. Microarray analysis using Affymetrix HG-U133 2.0 plus arrays was performed on duplicate samples.

Project description:We report changes in enrichment at chromatin of p63, KLF4 and H3K27ac following ectopic expression of wildtype or mutant p63+/- KLF4 for 72 hours in dermal BJ fibroblasts.

Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:MEK5 is activated by shear stress in large vessel endothelial cells (ECs) and contributes to the suppression of pro-inflammatory changes in the arterial wall. We used microarray analyses of total RNA from MEK5/CA-transduced HDMECs compared to LacZ control-transduced HDMECs to identify distinct classes of several regulated genes, including KLF4, eNOS, and ICAM. We conclude that MEK5 activation by shear stress may modulate inflammatory responses in the microvasculature, and these actions are partly mediated by KLF4.

Total RNA was isolated from 8 separate paired (derived from same primary isolate) MEK5/CA and LacZ transduced HDMEC lines
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.
