AIM: It is imperative to differentiate the role of host epigenetics from pharmacoepigenetics in resolving therapeutic response. Therefore, the objective was to identify how antipsychotic drugs influence epigenetic response on pharmacogenes. MATERIALS & METHODS: The study design was based on in vitro evaluation of pharmacoepigenetic response of haloperidol, clozapine and olanzapine. Post antipsychotic treatment, the alterations in expression of ABCB1, CYP1A2 and CYP3A4 were monitored, and followed up by promoter methylation and their target miRNA expression studies...

BACKGROUND: Malignant catatonia (MC) is a disorder consisting of catatonic symptoms, hyperthermia, autonomic instability, and altered mental status. Neuroleptic malignant syndrome (NMS) caused by antipsychotics is considered a variant of MC. Benzodiazepine (BZD) medications are safe and effective treatments providing rapid relief from MC. This case study reports a detailed clinical course of a case of MC associated with schizophrenia initially diagnosed as NMS that responded successfully to BZDs but not to dantrolene...

Using Fura-2AM microfluorimetry, we have shown for the first time that sigma-1 receptor antagonist, antipsychotic haloperidol, significantly inhibits glutoxim- and molixan-induced Ca(2+)-response in peritoneal macrophages. These results indicate possible involvement of sigma-1 receptors in the signal cascade induced by glutoxim or molixan and leading to intracellular Ca(2+) concentration increase in macrophages.

BACKGROUND: Older patients can be especially susceptible to antipsychotic-induced side effects, and the pharmacodynamic mechanism underlying this phenomenon remains unclear. We hypothesized that age-related epigenetic alterations lead to decreased expression and functionality of the dopamine D2 receptor (D2R), contributing to this susceptibility. METHODS: In this study, we treated young (2-3 months old) and aged (22-24 months old) C57BL/6 mice with the D2R antagonist haloperidol (HAL) once a day for 14 days to evaluate HAL-induced motor side effects...

Current antipsychotics reduce positive symptoms and reverse negative symptoms in conjunction with cognitive behavioral issues with the goal of restoring impaired occupational and social functioning. However, limited information is available on their influence on gliogenesis or their neurogenic properties in adult schizophrenia brains, particularly on GABAergic interneuron production. In the present study, we used young adult subventricular zone (SVZ)-derived progenitor cells expressing proteoglycan NG2 cultures to examine the oligodendrocyte and GABAergic interneuron genesis effects of several kinds of antipsychotics on changes in differentiation function induced by exposure to the NMDA receptor antagonist MK-801...

BACKGROUND: Cancer is commonly perceived as life-threatening and universally stressful; however, brief psychotic disorder, which occurs in response to extremely stressful events, has not been reported. CASE PRESENTATION: A 63-year-old woman, who was diagnosed as having pancreatic cancer with liver metastasis, became unresponsive with very little reaction to verbal contact after sequential life-threatening events, such as thrombosis of both pulmonary arteries and stenosis of the third portion of the duodenum, due to disease progression over 3 weeks beginning with oncological emergency hospital admission...

Many behavioral and biological effects of a psychoactive drug often undergo time-dependent change following even one single drug exposure. The present study examined whether one or two exposures of haloperidol, olanzapine or clozapine would also induce a time-dependent change in their behavioral effects in adolescent rats and whether such a change vary between sexes. Adolescent Sprague-Dawley rats (<40days old) were first treated with one single injection of haloperidol (0.05 and 0.1mg/kg, sc), clozapine (10...

The microglial hypothesis of schizophrenia suggests that its neuropathology is closely associated with neuroinflammation manifested, inter alia, by an increased expression of cytokines. However, clinical investigations imply that schizophrenia is a heterogeneous disease and in some groups of patients the activated inflammatory process does not contribute to the disease-associated impairment of brain function. Clinical studies revealed also an equivocal impact of antipsychotics on peripheral and CSF cytokines, whereas experimental research performed on the stimulated glia cultures showed their inhibitory effect on pro-inflammatory cytokine levels...

Previous studies into the mechanism of SSRI-antipsychotic synergism in our laboratory identified unique changes in the brain, particularly in the γ-aminobutyric acid (GABA)-A receptor and its modulators. This study examined the role of brain derived neurotrophic factor (BDNF)-cAMP response element binding (CREB) protein signaling pathways, including protein kinase B (AKT), glycogen synthase kinase (GSK)-3β and related molecules in the molecular response to haloperidol, fluvoxamine, combined haloperidol+fluvoxamine and clozapine treatments in rat frontal cortex, hippocampus and primary cortical neuronal cultures...

D-aspartate levels in the brain are regulated by the catabolic enzyme D-aspartate oxidase (DDO). D-aspartate activates NMDA receptors, and influences brain connectivity and behaviors relevant to schizophrenia in animal models. In addition, recent evidence reported a significant reduction of D-aspartate levels in the post-mortem brain of schizophrenia-affected patients, associated to higher DDO activity. In the present work, microdialysis experiments in freely moving mice revealed that exogenously administered D-aspartate efficiently cross the blood brain barrier and stimulates L-glutamate efflux in the prefrontal cortex (PFC)...

BACKGROUND: Older people are more susceptible to falls than younger people. Therefore, as the Dutch population ages, the total number of falls and costs associated with them will rise. The use of psychotropic drugs is associated with an increased risk of falling. To create tailored fall-prevention programmes, information on the magnitude of the association between fall incidents and specific psychotropic drugs or drug classes is needed. OBJECTIVE: The goal of this study was to delineate the associations between fall incidents and specific psychotropic drugs or drug classes...

The performance of a small, plastic drift tube ion mobility spectrometer (DT-IMS) is described. The IMS was manufactured using three-dimensional (3D) printing techniques and operates in the open air at ambient pressure, temperature, and humidity. The IMS housing and electrodes were printed from nonconductive polylactic acid (PLA, housing) and conductive polyethylene terephthalate glycol-modified polymer containing multiwalled carbon nanotubes (PETG-CNT, electrodes). Ring electrodes consisting of both an inner disk and an outer ring were used to prevent neutral transmission while maximizing ion transmission...

The spatial arrangement of cardiac myocytes (CMs) and other non-myocytes scaffolds, closely resembling native tissue, is essential to control the CM morphology and function for cardiac tissue regeneration. In the current study, micropatterned fibrous scaffolds were developed to establish a CM co-culture system with cardiac fibroblasts (CFs) and endothelial cells (ECs) as a potential in vitro drug screening model. To pursue a biomimetic approach to influence CM behaviors, strip, oval and wave-patterned mats were constructed by deposition of electrospun fibers on lithographic collectors, followed by precise stacking for cell co-cultures...

Outcome of imipramine (IMI) treatment was scrutinized on progression of haloperidol instigated tardive dyskinesia (TD). 0.2 mg/kg/rat dosage of haloperidol provided orally to rats for 2 weeks enhanced vacuous chewing movements that escalated when the process proceeded for 5 weeks. Following 2 weeks co-injection 5 mg/kg dosage of IMI was diminished haloperidol-instigated VCMs and fully averted following five weeks. The potency of 8-OH-DPAT-instigated locomotor activity exhibited higher in saline+haloperidol treated rats while not observed in IMI+ haloperidol treated rats...

Tardive dyskinesia (TD) is associated with the use of antipsychotic drugs such as D2 antagonist haloperidol (HP). The chronic use of HP is involved in the causation of free radicals and/or oxidative stress. In view of the nootropic, anti-anxiety, anti-inflammatory-like effects of rice bran oil (RBO) in a variety of investigations, we assessed the protective properties of RBO on HP-induced TD and neurochemical alteration. Rats treated with HP orally at a dose of 0.2 mg/kg/day for a period of 5 weeks developed VCMs which increased progressively as the treatment continued for 5 weeks...

Aripiprazole was the first antipsychotic developed to possess agonist properties at dopamine D2 autoreceptors, a groundbreaking strategy that presented a new vista for schizophrenia drug discovery. The dopamine D2 receptor is the crucial target of all extant antipsychotics, and all developed prior to aripiprazole were D2 receptor antagonists. Extensive blockade of these receptors, however, typically produces extrapyramidal (movement) side effects, which plagued first-generation antipsychotics, such as haloperidol...

Pentamidine is an effective trypanocidal drug used against stage 1 Human African Trypanosomiasis (HAT). At the blood-brain barrier (BBB), it accumulates inside the endothelial cells but has limited entry into the brain. This study examined transporters involved in pentamidine transport at the human and mouse BBB using hCMEC/D3 and bEnd.3 cell lines, respectively. Results revealed that both cell lines expressed the organic cation transporters (OCT1, OCT2 and OCT3), however, P-gp was only expressed in hCMEC/D3 cells...
