Project description:Histone deacetylase (HDAC) inibitors suppress cell proliferation of prostate cancer, but the detailed mechanisms are unknown. Moreover, HDAC includes 18 family members, namely HDAC1-11 and SIRT1-7, and differences of effects on prostate cancer proliferation among these enzymes are also unknown. Thus, we clarified differences of gene expression between prostate cancer cell line (LNCaP) treated with pan-HDAC inhibitors (TSA and OBP-801) or selective HDAC inhibitor (NCC-149, HDAC8-specific inhibitor)using cDNA microarray. LNCaP treated with TSA (1μM), NCC149 (2μM), OBP-801 (200nM) or DMSO for 24hrs, RNA was extracted from cells, and cDNA array was performed.

Project description:Schizophrenia is a group of severe mental disorders. MK-801 is a common chemical that is used to construct schizophrenic animal model. In the present study, male SD rats were received MK-801 (0.2 mg/kg) intraperitoneal injections for 2 weeks. PFC tissue samples were collected freshly when sacrificing the rats and then quickly frozen and stored under -80°C for RNA sequencing. Differentially-expressed genes (DEGs) were determined by using DESeq2. A total of 129 DEGs, including 50 down-regulated and 79 up-regulated DEGs, were determined. By comparing with the online database TargetScanHuman (Release 8.0) and miRDB (Version 6.0), we found 4 genes (SIK1, TWIST1, BTG2, EGR2) that were altered in the schizophrenic model rat PFC and also are potential targets of miR-25.

Project description:N-Methyl-D-aspartate receptors (NMDAr), widely located around the central nervous system, are known to be involved in behavioral disorders. Dizocilpine (commonly referred to as MK-801) is a well known non-competitive NMDAr antagonist. We treated rats with intraperitoneal injection [0.08 (low-dose) and 0.16 (high-dose) mg/kg] of MK-801. In one experiment, 40 min after NaCl (vehicle control) and MK-801 (0.08 mg/kg) injection, electrocorticogram (ECoG) signals were analyzed. In the second experiment, 40 min post-injection, the whole brain of each animal was rapidly removed and separated into amyglada, cerebral cortex, hippocampus, hypothalamus, midbrain and ventral striatum) on ice, followed by analysis using a 4x44K DNA microarray chip. Spectral analysis revealed that a single systemic injection of MK-801 significantly and selectively augmented the power of baseline (30-80 Hz) frequency oscillations. DNA microarray analysis showed the largest number (up- and down- regulations) of gene expressions in the cerebral cortex (378), midbrain (376), hippocampus (375), ventral striatum (353), amygdala (301), and hypothalamus (201) under low-dose of MK-801. Under high-dose, ventral striatum (811) showed the largest number of gene expression changes. Gene expression changes were functionally categorized to reveal expression of genes and function varies with each brain region. MK-801 increases the synchrony of baseline oscillations, causing very early changes in gene expressions in rat brain after acute MK-801 treatment, a first report. The overall goal of the present study was to identify gene expression patterns along rat chromosomes in different brain regions after a single injection of MK-801, which exerts a longer acute effect than ketamine on ongoing brain activities. Two approaches were taken, first electrophysiological and send molecular analysis, where the brain of MK-801-treated rats was subjected to a genome-wide transcriptome mapping analysis (~4400 genes) in the cerebral cortex, midbrain, hippocampus, ventral striatum, amygdala, and hypothalamus regions.

Results: Spectral analysis revealed that a single subcutaneous injection of MK-801 significantly and selectively augmented the power of spontaneous gamma and higher-frequency oscillations. The results from DNA microarray analysis of 4400 genes showed the largest number (up- and down- regulations) of gene expressions in the cerebral cortex (378), midbrain (376), hippocampus (375), ventral striatum (353), amygdala (301), and hypothalamus (201) under low-dose of MK-801. Under high-dose, ventral striatum (811) showed the largest number of gene expression changes. These genes represented... Conclusions: Our results reveal that MK-801 triggered i) an increase in the power of gamma oscillations, and ii) simultaneously caused very early changes in gene expressions in the rat brain, representing a first such inventory of gene expression profiles in brain after acute MK-801 treatment.
