Project description:hybridisation of mRNA from HaCaT keratinocytes expressing GLI1 or GLI2 in an tet-inducible manner for 24h or 72h on Incyte clone set Detailed information about the protocols we used for array production, hybridisation and analysation and the biological background of our experiments can be found in our publications: PMID: 15140221, 14691458, 12165851 Keywords = GLI1/2 target genes Keywords: time-course
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:Cidofovir is an acyclic nucleoside phosphonate with strong antiviral activity against a broad spectrum of DNA viruses. Although it has previously been shown that cidofovir exerts an antiproliferative effect on HPV positive cells by the induction of apoptosis, the exact mechanism of action remains to be unraveled. In order to study the activity of cidofovir against HPV, gene expression profiling was performed in cidofovir-treated and cidofovir-resistant HeLa, HaCaT, and PHK cells by means of microarrays (HG-U133 Plus 2, Affymetrix). Controls (untreated HeLa, HaCaT, and PHK wild-type cells): 72h of growth. Cidofovir treated (50 M-BM-5g/ml) HeLa, HaCaT, and PHK cells: 72h of growth. Cidofovir resistant cells (HeLa #52 and HaCaT #51): 72h of growth. All samples were performed in triplicates.
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.
