Objective(s): Present study investigated the neuroprotective effects of selegiline and the molecular mechanisms involved in methamphetamine-induced neurotoxicity.Materials and Methods: Male wistar rats were randomly divided into six groups (10 rats in each group). Group 1 and group 2 received normal saline and methamphetamine (10 mg/kg),...
OBJECTIVE To evaluate whether cardiomyocyte membrane structure and cell/extracellular matrix adhesion alterations perturb the cadherin/catenin complex in the hypertrophic cardiomyopathy (HCM). METHODS Hypertrophic cardiomyopathic hamster (UM-X7.1 strain) and human hearts were studied by light and electron microscopy, Northern and Western blot analyses and immunohistochemistry. RESULTS Inter...
The AMP-activated protein kinase (AMPK) is an alphabetagamma heterotrimer that is activated by low cellular energy status and affects a switch away from energy-requiring processes and toward catabolism. While it is primarily regulated by AMP and ATP, high muscle glycogen has also been shown to repress its activation. Mutations in the gamma2 and gamma3 subunit isoforms lead to arrhythmias associ...
It has previously been demonstrated that the insulin-mimetic agent trypsin stimulates autophosphorylation of purified insulin receptors and activates the insulin receptor tyrosine kinase in vitro. We now report the effects of trypsin on whole cell tyrosine kinase activation and insulin receptor autophosphorylation. Trypsin treatment of intact adipocytes produces a time-dependent stimulation of ...
Stabilization of beta-catenin by inhibiting the activity of glycogen synthase kinase-3beta has been shown to initiate axis formation or axial patterning processes in many bilaterians. In hydra, the head organizer is located in the hypostome, the apical portion of the head. Treatment of hydra with alsterpaullone, a specific inhibitor of glycogen synthase kinase-3beta, results in the body column ...
Glycogen synthase kinase-3 (GSK-3) is a critical, negative regulator of diverse signaling pathways. Lithium is a direct inhibitor of GSK-3 and has been widely used to test the putative role of GSK-3 in multiple settings. However, lithium also inhibits other targets, including inositol monophosphatase and structurally related phosphomonoesterases, and thus additional approaches are needed to att...
Alzheimer's disease (AD) is characterized by cognitive impairment, progressive neurodegeneration and formation of amyloid-beta (Abeta)-containing plaques and neurofibrillary tangles composed of hyperphosphorylated tau. The neurodegenerative process in AD is initially characterized by synaptic damage accompanied by neuronal loss. In addition, recent evidence suggests that alterations in adult ne...
