Project description:Antipsychotic drugs (APDs) have been reported to ease psychotic symptoms in the clinic. miRNAs have also been identified that can regulate the expression of genes/proteins related to possible molecular mechanisms of drug action. To reveal APD-induced miRNA modulations in glial cells, we analyzed miRNA expression in subchronically APD-treated C6 cells by using a miRNA microarray.

Project description:Atypical antipsychotic Clozapine has a superior antipsychotic and antimanic effects compared to other antisphicotics. Its widespread use was limited by the side effects of agranulocytosis, cardiomyopathy and metabolic anomalies such as weight gain, and diabetes. Very little is known about mechanisms by which Clozapine works. The aim of this experiment is to compare the chronic gene expression profile of the atypical antipsychotic Clozapine to the typical antipsychotic drug Haloperidol using gene expression Microarray in order to understand the intercellular mechanism behind the therapeutic and the toxic effects of Clozapine. Experiment Overall Design: The study was designed to compare the chronic therapeutic and toxic expression profile of Clozapine to Haloperidol in the mouse brain. All experiments were performed in male C57BL mice at four weeks of age (Biological services, University Collage London). Several theoretical and practical considerations influenced the final experimental design. To avoid the effect of injections on genes expression and to simulate the clinical scenario in human, both drugs were applied to the animals drinking water using the maximum human therapeutic dose (i.e. 1.6mg/kg/day for Haloperidol and 12mg/kg/day for Clozapine). Thirty animals were divided equally between three treatment groups and received either Haloperidol (10 animals), Clozapine (10 animals) or no treatment (10 animals) for 12 weeks. After twelve weeks, the total RNA from the right forebrains were extracted and hybridized to the Affymetrix MOE430A array. In all the Microarray experiments we have avoided pooling and each RNA sample was an independent biological replicate. The total numbers of used arrays were 30 Affymetrix MOE430A arrays.

After four weeks,the plasma drug level for both drugs was assesed by Tandem mass Spectrometry LC- MS/MS. The total RNA from the right forebrains of nine selected animals (three from each treatment group) were extracted and hybridized to the Affymetrix U74Av2. In all the Microarray experiments we have avoided pooling and each RNA sample was an independent biological replicate. The total numbers of used arrays were 9 Affymetrix U74Av2.

Project description:This work reveals the effect of antipsychotics on DNA methylation using the cell model. After the treatment of antipsychotics, haloperidol and risperidone, DNA methylation profiles obtained by Illumina HumanMethylation450 beadchip were examined.

Project description:Although antipsychotics are routinely used in the treatment of schizophrenia for last decades, their precise mechanism of action is still unclear. In this study we investigated changes in PC12 cells’ proteome under the influence of clozapine, risperidone and haloperidol to identify protein pathways regulated by the antipsychotics. Analysis of the protein profiles in two time points: after 12 and 24 h of incubation with drugs revealed significant alterations in 510 proteins. Further canonical pathway analysis determined signal transduction pathways and biological processes regulatednby drug treatment. Interestingly, all tested drugs have caused changes in PC12 proteome which correspond to inhibition of cytokines: tumor necrosis factor (TNF) and transforming growth factor beta 1 (TGF-β1), what can be linked to the immunological and viral hypothesis of schizophrenia. We found, that the 12-hour incubation with clozapine caused up-regulation of protein kinase A signalling and translation machinery. After 24 h of treatment with clozapine, the inhibition of the actin cytoskeleton signalling and Rho proteins signalling was revealed. Obtained results suggests that mammalian target of rapamycin complex 1 (mTORC1) and 2 (mTORC2) play a central role in the signal transduction of clozapine.

Project description:In this study, a comprehensive evaluation model for studying the cardiac toxicity of antipsychotic drugs was established by using iPSC-CMs. Six antipsychotic drugs, including aripiprazole, risperidone, quetiapine, haloperidol, clozapine, and olanzapine, all induced concentration-dependent QT prolongation in iPSC-CMs upon acute administration, and high concentrations of these drugs caused disorganized sarcomere arrangement in iPSC-CMs.

Project description:SD rats were dosed with gold standard antipsychotic therapies, haloperidol or risperidone, at doses aimed at achieving therapeutically relevant drug exposures. Tissues were collected after 21 days of delivery to examine the impact of this treatment on gene expression in frontal cortex, hippocampus and striatum.
