Angelman syndrome (AS) is caused by the loss of Ube3A, an ubiquitin ligase that commits specific proteins to proteasomal degradation. How this defect causes autism and other pathological phenotypes associated with AS is unknown. Long-term depression (LTD) of excitatory synaptic transmission mediated by type 5 metabotropic glutamate (mGlu5) receptors was enhanced in hippocampal slices of Ube3A(m...
Extraordinary behavioral flexibility is necessary in order to meet energy needs. An animal must know when and where to search for food, guard itself and its offspring against predators, and continuously adjust foraging behavior as the changing environment dictates. These pressures have selected for the ability to accomplish numerous functions simultaneously. This is particularly necessary durin...
We studied group-I metabotropic glutamate (mGlu) receptors in Pahenu2 (ENU2) mice, which mimic the genetics and neurobiology of human phenylketonuria (PKU), a metabolic disorder characterized, if untreated, by autism, and intellectual disability (ID). Male ENU2 mice showed increased mGlu5 receptor protein levels in the hippocampus and corpus striatum (but not in the prefrontal cortex) whereas t...
سابفه و هدف: مواجهه حاد با نیکل باعث تغییر برنامه بیان ژن سلول های طبیعی گردیده و الگوی بیان ژن مشابه با سرطان های ناشی از نیکل را القاء می کند. هدف از این مقاله، بررسی مکانیسم های مختلف سرطانزایی نیکل می باشد. مواد و روش ها: مرور سیستماتیک در سایت های pubmed و google scholar بر قدرت سرطان زایی ترکیبات نیکل در مدل های حیوانی و سلول های جوندگان در شرایط برون تنی صورت گرفت. نتایج: شواهد منتشر شده...
Brief metabotropic glutamate receptor (mGluR) activation leads to plasticity of AMPA receptor (AMPAR) synaptic transmission. To test whether mGluR-mediated plasticity of AMPAR transmission is influenced by recent neuronal activity, we manipulated visual activity in Xenopus laevis tadpoles in vivo. We compared mGluR-mediated plasticity of AMPAR transmission in optic tectal cells of tadpoles with...
Neurons adapt to seizure activity structurally and functionally to attenuate hyperactive neural circuits. Homer proteins provide a scaffold in the postsynaptic density (PSD) by binding to ligands through an EVH1 domain and to other Homer proteins by a coiled-coil domain. The short Homer isoform 1a (H1a) has a ligand-binding domain but lacks a coiled-coil domain and thus acts in a dominant-negat...
