Human placenta-derived cell line (JEG-3): Control vs. valproic acid(VPA)-treated

ABSTRACT: 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.

Expression data from human hepatic stellate cell line LX2 treated with suberoylanilide hydroxamic acid (SAHA) or valproic acid (VPA)

Project description:Suberoylanilide hydroxamic acid (SAHA) and valproic acid (VPA) are both histone deacetylases inhibitor (HDACi), and are able to attenuate the activation of hepatic stelllate cells. To explore the underlying molecular mechanisms, we performed gene expression profile analyses of human hepatic stellate cell line LX2 treated with SAHA or VPA for 24 hours. Duplicate experiments were performed: Untreated LX2, SAHA treated LX2 and VPA treated LX2.

Transcription profiling of Mus Musculus embryonic stem cell line R1 exposures to Valproic acid and VPA analogs to investigate VPA as a potent inducer of neural tube defects

Project description:Valproic acid (VPA) is a potent inducer of neural tube defects (ntd:s) in both human and mouse, but its mechanism of teratogenicity is not know. The mouse embryonic stem cell line R1, may be relevant as an in vitro model of teratogenicity and was evaluated with exposures to VPA,and the two VPA anlogs (S)-2-pentyl-4-pentynoic acid, and 2-ethyl-4-methyl-pentanoic acid to profile the gene expression response. Those profiles may reveal biomarkers of teratogenic exposures in an in vitro system as well as give mechanistic input of the teratogenicity of VPA.

Identification differentially expressed genes upon valproic acid treatment

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) CMK and CMY cells were treated with VPA for 24h and 48h with 1mM or 2mM VPA. Their gene expression profile was compared against the untreated control.

Expression data from untreated and valproic acid (VPA) treated CD34+ Hematopoietic Stem Cells (HSCs)

Project description:Histone deacetylase (HDAC) inhibitors are widely utilized in hematopoietic malignance therapy; nevertheless, little is currently known concerning their effects on normal myelopoiesis. In order to investigate a putative interference of HDAC inhibitors in myeloid commitment of hematopoietic stem/progenitor cells (HSPCs) we treated CD34+ cells with valproic acid (VPA). Moreover, we investigate changes in gene expression induced by VPA treatment on HSPCs, by means of microarray analysis in VPA treated and untreated (CTR) CD34+ cells. VPA treatment induced H4 histone acetylation in CD34+ cells and blocked them in G0-G1 phase of cell cycle. CD34 expression is maintained for a longer time in VPA treated cells, while the physiological decrease of CD34 antigen occurred in CTR cells. Moreover, VPA favored erythrocyte and megakaryocyte differentiation at the expense of granulocyte and mono-macrophage lineages, as demonstrated by immunophenotyping, morphological and clonogenic analysis. Finally, we demonstrated that VPA up-regulated master gene regulators of erythrocyte and megakaryocyte differentiation (GFI1B and MLLT3) through histone iper-acetylation of their promoters. These results indicate that VPA treatment enhances erythrocyte and megakaryocyte differentiation at the expense of granulocyte and mono-macrophage one. Microarray data provide for the first time a detailed molecular support for the biological effects promoted by VPA treatment in HSPCs.

Transcription profiling of mouse control 25-dpc embryos from control vs. valproic acid (VPA) treated dams and control P19 mouse EC cells vs 1 mM sodium valproate for 24 h

Project description:Valproic acid (VPA) is a potent inducer of neural tube defects (NTDs), but its mechanism of teratogenicity is not known. To study the transcriptional response of VPA during the susceptible period, i.e. when VPA is likely to exert most of its teratogenic effect, RNA was extracted from 8.25-dpc embryos (6 h post treatment) from control and VPA-treated dams, and subjected to microarray analysis (four arrays). To be more useful for risk assessment, in vitro models, using cells, may bridge biomarkers discovered by gene expression profiling in an animal in vivo model. Since pluripotent embryocarcinoma (EC) cell lines may be relevant models for early embryonic cells, P19 mouse EC cells were treated with or without 1 mM sodium valproate for 24 h and alos subjected to microarray analysis (four arrays).
