Project description:Transcriptional profiling of human placenta-derived JEG-3 cell line comparing vehicle control with 7.38 mM of valproic acid(VPA)-treated JEG-3 cells for 48 hr. 7.38 mM valproic acid(VPA) induced the 30% inhibiotion of JEG-3 cell proliferation, G1 phase cell cycle arrest and the reduction of cell size. The Goal was to analyze the mechanism of valproic acid-induced adverse effects in placental cells.

The Goal was to analyze the mechanism of valproic acid-induced adverse effects in placental cells. Two-condition experiment, JEG-3 cells vs. valproic acid(VPA)-treated JEG-3 cells. Biological replicates: 3 control replicates, 3 VPA-treated replicates.
Project description:Valproic acid (VA) is a small-chain branched fatty acid, widely used as anticonvulsant, and mood stabilizer to treat psychiatric illness. Valproic acid is also known to inhibit the histone deacetylases (HDACs), which makes it as a potent antitumor agent in alone or in combination with other cytotoxic drugs. Beside its conventional activities, valproic acid reported to have much broader, complicated effects and affect many complex physiological processes. However the molecular mechanisms of valproic acid are unclear. So, we used budding yeast transcriptome analysis to better understand the molecular mechanism of action of valproic acid. The clusters of differentially expressed genes in microarray after VA (6mM) treatment and their functional enrichment analysis revealed its overall effects on various biological processes such as cell cycle, signal transduction, metabolism, transcription, ubiquitination, transporter activities and many more. The microarray data were validated by quantitative real-time PCR.
Project description:The goal of this study is to define genes that are differentially expressed in Down syndrome leukemic blasts after treatment with valproic acid (VPA) Here we report the identification gene sets that are downregulated in Down syndrome leukemic cell lines after exposure to valproic acid (VPA)
Project description:New therapy options are required for relapsed B-cell precursor ALL patients in order to improve survival and reduce adverse acute and late effects. We observed a synergistic anti-leukemic activity of concomitant treatment with bortezomib and valproic acid in BCP-ALL cells. In this experiment we aimed to identify the pathways modulated after concomitant treatment with bortezomib and valproic acid. Reh cells treated with either bortezomib, valproic acid, or the combination of both normalized to a untreated control.
