Project description:To gain a better understanding of the zinc effect on prostate cells, gene expression profiling analyses were conducted using HPR-1 and PC-3 cells treated with or without zinc (1,500 ng/ml) after 24 hrs serum-depletion. Zinc effect on gene expression was evaluated at 1, 3, and 6 hrs of zinc treatment compared to the control, using human genome survey microarray chips. A total of 6,110 identified genes exhibited three expression patterns in response to zinc a threshold of ±2.5 folds: suppressed (3,534 in PC-3; 1,953 in HPR-1), increased (571 in PC-3; 872 in HPR-1), and otherwise altered (16 in PC-3; 13 in HPR-1). Keywords: Zinc effect, time course, cell type comparison
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.
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. One-condition experment, gene expression of 3A6
Project description:Failure in intracellular zinc accumulation is a key process in prostate cancerogenesis. Although prostate cancer cells can accumulate zinc after long-term exposure, chronic zinc oversupply may accelerate prostate carcinogenesis or chemoresistance. As a model of prostate cancerogenesis, long-term zinc-treated (zinc accumulating) cell lines 22Rv1, and PC-3 were used. In this dataset we investigated how long-term zinc treatment is associated with changes of cell proteome in these cells as determined by LC-MS. Preparation of long-term zinc-treated cells is described in Holubova et al., 2014, and Raudenska et al, 2019.
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. 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. Two-condition experiment, KP MSCs vs. 3A6 MSCs.
