Metabotropic glutamate receptors mGluR1 and mGluR5 stimulate phospholipase C, leading to an increased inositol trisphosphate level and to Ca(2+) release from intracellular stores. Cyclothiazide (CTZ), known as a blocker of AMPA receptor desensitization, produced a non-competitive inhibition of [Ca(2+)](i) increases induced by mGluR agonists in HEK 293 cells… (More)
To better characterize the roles of metabotropic glutamate receptors (mGluRs) in physiological and pathophysiological processes, there is an important need to learn more about the structural features relevant to the design of novel, high-affinity ligands that are family and subtype specific. To date, many of the biological studies that have been conducted… (More)
A comparative study of the neuroprotective and nootropic activities of two pharmaceutical substances, the HLDF-6 peptide (HLDF-6-OH) and its amide form (HLDF-6-NH2), was conducted. The study was performed in male rats using two models of a neurodegenerative disorder. Cognitive deficit in rats was induced by injection of the beta-amyloid fragment 25-35 (βA… (More)
300 Proteasome is a multisubunit protein complex that exhibits proteolytic activity and is present in the nuclei and cytoplasm of cells. The 20S proteasome, which has a molecular weight of 700 kDa and a sedimenta tion coefficient of 20S, is present as a proteolytic core in a more complex particle, the 26S proteasome . The degradation of proteins in the… (More)
Bovine brain cDNA cloned earlier and attributed to calmodulin-independent adenylate cyclase encodes the neural cell adhesion molecule (N-CAM). The expression of N-CAM mRNA in Xenopus laevis oocytes increases their basal adenylate cyclase activity. Polyclonal antibodies against synthetic peptide A, VAENQQGKSKAAHFV (664-678 amino acid residues of bovine… (More)
The neuroprotective effect of Thr-Gly-Glu-Asn-His-Arg hexapeptide (HLDF-6), a biologically active fragment of the differentiation factor of human leukemia cells (HLDF), was demonstrated on models of Alzheimer’s disease in vivo and in vitro. The syndromes of this pathology were induced in male rats by injection of beta-amyloid peptide (25–35) and ibotenic… (More)
A photochemical approach to the synthesis of the aminobicycloheptane 6a is reported. This compound assumes an extended glutamate conformation, and for this reason was created to further probe the structural features relevant to achieving selectivity for the subtypes of the metabotropic glutamate family of receptors.
In CHO-K1 cells, heat shock strongly activated reporter-gene expression driven by the cytomegalovirus immediate-early (CMV-IE) promoter from adenoviral and plasmid vectors. Heat shock treatment (2h at 42.5 °C) significantly enhanced the promoter DNA-binding activity in nuclear extracts. In CHO cells expressing mGluR1a and mGluR5a receptors under the control… (More)
The synthesis of the 1-amino derivative of (2R,4R)-4-aminopyrrolidine-2,4-dicarboxylic acid (1-amino-APDC), a selective metabotropic glutamate ligand, is disclosed. This compound acts as a partial agonist of the group II mGluRs and shows pronounced neuroprotective properties in the NMDA model of cell toxicity.
In this study, we performed transcriptome profiling of oligodendrocyte culture of mice treated with the remyelinating therapeutic agent benztropine in the presence and absence of interferon gamma (IFNγ). The results of this work are important for understanding the expression profile of oligodendrocytes under conditions of systemic inflammation in the… (More)
