Project description:In this study, we examined the effects of VOCs exposure in humans on gene expression using microarray analysis. We recruited participants who had short-term exposure, long-term exposure, or no exposure. We then analyzed changes in gene expression in blood samples from these participants. A total of 866 genes were upregulated, while 366 genes were downregulated in the short-term exposure group. Similarly, in the long-term exposure group, a total of 852 and 480 genes were up- or downregulated, respectively. Hierarchical clustering analysis was used to divide the clustered genes into nine clusters to investigate the expression of variations in accordance with the exposure period. Further research is required to determine the time-dependent effects of VOCs on epigenetic regulation of gene expression. Gene expression of mRNA in human blood samples (IRB #AS 14039) divided into three groups: control (unexposed workers; n = 12), short-term exposure (workers exposed to VOCs for less than 10 years; n = 12), and long-term exposure (workers exposed to VOCs for more than 10 years; n = 12) was experimented by microarray analysis after exposure to VOCs
Project description:To more concretely elucidate the long-term effects of chronic SSRI exposure during adulthood, the long-term consequences of chronic fluoxetine (12 mg/kg) versus vehicle treatment during adulthood (postnatal day (PND) 67-88) on gene expression in the hippocampus were investigated. The study showed that adult chronic fluoxetine exposure causes on the long-term changes in the expression of genes related to, amongst others, myelination
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.
