Myocardial infarction due to ischemia accounts for majority of deaths among cardiovascular disorders. Isoproterenol (ISO) induced myocardial infarction and the protection offered by piperine was investigated in the present report. Lipid profile analysis by determining the levels of cholesterol, phospholipids, triglycerides and lipoproteins in serum and heart tissues showed anti-dyslipidemic action of piperine against ISO induced myocardial injury by modulating the ISO induced altered lipid profiles, maintaining to near control values...

Early-life stress (ES) increases the vulnerability to develop psychopathologies and cognitive decline in adulthood. Interestingly, this is often comorbid with metabolic disorders, such as obesity. However, it is unclear whether ES leads to lasting metabolic changes and to what extent this is associated with the ES-induced cognitive impairments. Here, we used an established chronic ES mouse model (from postnatal day (P) 2 to P9) to investigate the short- and long-term effects of ES exposure on parameters of the adipose tissue and the leptin system (i...

Resolution of inflammation is important for physiological homeostasis. Chronic inflammatory diseases may be caused by abnormal resolution of inflammation. However, what causes a failure of inflammatory resolution is unclear. Here we investigated the involvement of high mobility group box 1 (HMGB1) protein in the control of inflammatory resolution as a 'anti-resolution factor'. We first confirmed the increased expression of HMGB1 and prostaglandin reductase 1 (PTGR1) in inflammatory conditions and HMGB1-mediated regulation of the expression of PTGR1...

An endoplasmic reticulum (ER)-resident protein that regulates cytosolic and ER free-Ca(2+) concentration by induction of store-operated calcium entry. That is the original definition of STIM2 and its function. While its activity strongly depends on the amount of calcium stored in the ER, its function goes further to intracellular signalling and gene expression. Initially undercovered by the prominent function of STIM1, STIM2 became to be vital in mice, gradually emerging as an important player in the nervous system, and cooperating with STIM1 in the immune system...

Over the past years, the use of antidepressants and neuroleptics has steadily increased. Although incredibly useful to treat disorders like depression, schizophrenia, epilepsy, or mental retardation, these drugs display many side effects. Toxicogenomic studies aim to limit this problem by trying to identify cellular targets and off-targets of medical compounds. The baker yeast Saccharomyces cerevisiae has been shown to be a key player in this approach, as it represents an incredible toolbox for the dissection of complex biological processes...

Diphenylarsinic acid (DPAA) was a major compound found in the arsenic poisoning incident that occurred in Kamisu, Ibaraki, Japan in 2003. People exposed to DPAA via contaminated well water suffered from several neurological disorders, including cerebellar symptoms. We previously reported that DPAA induces cellular activation in cultured rat cerebellar astrocytes, dose-dependent promotion of cell growth (low DPAA), cell death (high DPAA), and increased phosphorylation of mitogen-activated protein (MAP) kinases (p38MAPK, SAPK/JNK, and ERK1/2)...

Global developmental delay (GDD), often accompanied by intellectual disability, seizures and other features is a severe, clinically and genetically highly heterogeneous childhood-onset disorder. In cases where genetic causes have been identified, de-novo mutations in neuronally expressed genes are a common scenario. These mutations can be best identified by exome sequencing of parent-offspring trios. De novo mutations in the guanine nucleotide-binding protein, beta 1 (GNB1) gene, encoding the Gβ1 subunit of heterotrimeric G proteins, have recently been identified as a novel genetic cause of GDD...

Disruption of apical-basal polarity is implicated in developmental disorders and cancer; however, the mechanisms connecting cell polarity proteins with intracellular signaling pathways are largely unknown. We determined previously that membrane-associated guanylate kinase (MAGUK) protein discs large homolog 5 (DLG5) functions in cell polarity and regulates cellular proliferation and differentiation via undefined mechanisms. We report here that DLG5 functions as an evolutionarily conserved scaffold and negative regulator of Hippo signaling, which controls organ size through the modulation of cell proliferation and differentiation...

Degradation of the extracellular matrices in the human body is controlled by matrix metalloproteinases (MMPs), a family of more than 20 homologous enzymes. Imbalance in MMP activity can result in many diseases, such as arthritis, cardiovascular diseases, neurological disorders, fibrosis, and cancers. Thus, MMPs present attractive targets for drug design and have been a focus for inhibitor design for as long as three decades. Yet, to date, all MMP inhibitors have failed in clinical trials because of their broad activity against numerous MMP family members and the serious side effects of the proposed treatment...

Dopa-responsive dystonia (DRD) is a rare inherited disorder characterized by childhood-onset dystonia with diurnal fluctuation and dramatic response to levodopa. DRD is caused by the mutations in the genes encoding the enzymes involved in the dopamine and tetrahydrobiopterin (BH4) biosynthesis, including the GTP cyclohydrolase 1 (GCH1) gene and the tyrosine hydroxylase (TH) gene. In order to improve the diagnosis and expand the knowledge of the disease, we collected and analyzed relevant data of clinical diagnosis and molecular mutational analysis in five Chinese patients with DRD...

Tunicamycin (TM) induces endoplasmic reticulum (ER) stress and inhibits N-glycosylation in cells. ER stress is associated with neuronal death in neurodegenerative disorders, such as Parkinson's disease and Alzheimer's disease, and most patients complain of the impairment of olfactory recognition. Here we examined the effects of TM on aversive olfactory learning and the underlying synaptic plasticity in the main olfactory bulb (MOB). Behavioral experiments demonstrated that the intrabulbar infusion of TM disabled aversive olfactory learning without affecting short-term memory...

Epilepsy is characterized by spontaneous recurrent seizures and temporal lobe epilepsy (TLE) is the most common serious neurological example of acquired and frequent epilepsy. Oxidative stress is recognized as playing a contributing role in several neurological disorders, and most recently have been implicated in acquired epilepsies. The MTs occur in several brain regions and may serve as neuroprotective proteins against reactive oxygen species causing oxidative damage and stress. The main aim of this work was to describe the immunohistochemical localization of MT in the specimens derived from the patients affected by TLE...
