Project description:H3K27me3 is a chromatin modification depositied by Suz12, a component of the Polycomb Group 2 complex, and is associated with transcriptional repression. In contrast, H3K79me2 is a chromatin modification associated with active gene transcription. It is deposited by the histone methyltransferase Dot1L and generally is localized just downstream of the transcriptional start site and extends down the body of the gene. To gain insight into the transcriptional state of genes in hES cells, chromatin immunoprecipitation coupled with massive parallel sequencing (ChIP-seq) was performed to determine the genome-wide occupancy of the H3K27me3 and H3K79me2 chromatin modifications and genome-wide occupancy of the Suz12. DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing A sample of whole cell extract was sequenced and used as the background to determine enrichment. ChIP was performed using an antibody against H3K27me3, H3K79me2, and Suz12 (Abcam).

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.
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.
