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.
Project description:Seven male C57BL/6 mice, at 10 weeks of age, were injected daily intraperitoneally with 0.5 mg/kg of haloperidol, for 28 days. A control group of six animals was injected with vehicle only (saline).
Project description:Quetiapine is an atypical neuroleptic with a pharmacological profile distinct from classic neuroleptics. It is currently approved for treating patients with schizophrenia, major depression and bipolar I disorder. However, its cellular effects remain elusive. We used microarrays to characterize RNA transcript levels in the brains of mice chronically treated with quetiapine, the neuroleptic haloperidol, or vehicle. We further characterized particular RNA transcripts in cortical cell cultures. Mice were given one of 5 treatments (vehicle, 1 mg/kg haloperidol, 0.3 mg/kg haloperidol, 100 mg/kg quetiapine, 10 mg/kg quetiapine). Pooled tissue samples were used for microarray analysis of gene expression in the frontal cortex (FC) and striatum (STR). Frontal cortex gene targets were subsequently verified with quantitative real-time PCR (qRT-PCR) from the same cohort of mice and an independent cohort.
Project description:Two month-old male Wistar rats received either resveratrol (10 mg/kg) plus N-acetylcysteine (400 mg/kg) or vehicle during 5 consecutive days. The second day of treatment, a concentrated solution of kanamycin and furosemide was placed on the round window of the right ears of rats receiving treatment or vehicle. Hearing was assessed by recording auditory brainstem responses before and 5, 16 and 23 days after starting the treatment with resveratrol and N-acetylcysteine. Cochlear samples were taken at the end of the treatment (5 days) and once the treatment had been suspended (23 days) to study cochlear cytoarchitecture and the evolution of the expression of oxidative stress, antioxidant defense and inflammation genes by using PCR arrays and RT-qPCR.
Project description:To identify potential candidate genes for future pharmacogenetic studies of antipsychotic (AP)-induced extrapyramidal symptoms (EPS), we used gene expression arrays to analyze changes induced by risperidone in mice strains with different susceptibility to EPS This study is a part of a convergent functional genomic approach that plans to integrate the data presented here with: data from gene expression analysis of neuroblastoma cell line under treatment with risperidone; and data from gene expression analysis of peripheral blood from first psychotic patients treated with risperidone. Gene expression was assessed by microarray (Affymetrix GeneChip® Arrays MG 430 PM) in mice treated with risperidone 1mg/kg for three consecutive days
Project description:RCCHanTM:WIST male rats were administered for 7 days by oral gavage with vehicle (corn oil) or 100 mg/kg/day of pregnenolone-16α-carbonitrile(PCN). We used microarrays to evaluate gene expression profiling in rat liver at the early phase of treatment with PCN.
Project description:We performed RNA sequencing on tumors harvested from OV5398 (ovarian) PDX treated for 40-50 days with either control vehicle (PEG), 100 mg/kg BID INX-315 or 200 mg/kg QD INX315.
Project description:To investigate the mechanisms of endotoxin-mediated kidney injury as well as renoprotective effects of endotoxin preconditioning, we performed manual microdissection of S2/S3 proximal tubules in mice as follows: 1) Non-preconditioned mice subjected to single-dose 5 mg/kg LPS (0111:B4) i.p. for 4 hrs. 2) Non-preconditioned mice subjected to single-dose 5 mg/kg LPS (0111:B4) for 24 hrs. 3) Preconditioned mice subjected to 0.25 mg/kg LPS followed 24 hour later by 5 mg/kg LPS for 4 hrs. 4) Preconditioned mice subjected to 0.25 mg/kg LPS followed 24 hour later by 5 mg/kg LPS for 24 hrs. 5) Control mice (untreated).
