Project description:Colorectal carcinoma (CRC) is often characterized by chromosomal instability (CIN) which has been associated with a poor prognosis. Disease-related de novo methylation often causes gene repression that may complement chromosomal losses or mutations. To compare CpG island methylation and chromosomal abnormalities in colorectal cancer, we determineded unbalanced chromosomal changes by aCGH of CRCs that were also profiled for aberrant de novo DNA methylation at 23,000 CpG islands of the human genome (Gebhard et al. 2010; and unpublished data). Refer to individual Series. This SuperSeries is composed of the following subset Series: GSE25221: CpG island methylation in colorectal cancer GSE25228: Chromosomal abnormalities in colorectal cancer
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: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.
