Thyrotropin is the primary hormone that, via one heptahelical receptor, regulates thyroid cell functions such as secretion, specific gene expression, and growth. In human thyroid, thyrotropin receptor activation leads to stimulation of adenylyl cyclase phospholipase C cascades. However, G proteins involved in action have been only partially defined. membranes gland, we immunologically identified alpha subunits Gs short, long, Gi1, Gi2, Gi3, G(o) (Go2 another form Go, presumably Go1), Gq,...
The human thyrotropin receptor leads upon activation to the stimulation of phospholipase C and adenylyl cyclase.It is presently not known whether this bifurcating signaling occurs via two different G-proteins (Gq/,, GB) or one G-protein (GJ Receptor-activated G, releases P-y subunits as, which then could regulate cyclase, respectively.In order elucidate pathways induced by activated thyroid-stimulating hormone (TSH) receptor, we studied coupling TSH Gdll in thyroid membranes.TSH...

Regulation of effector functions by muscarinic acetylcholine receptor subtypes is mediated pertussis toxin-sensitive and -insensitive G proteins. In membranes from human embryonic kidney 293 cells transfected with m1, m2, m3 acetycholine receptors, we detected the proteins Gi1, Gi2, Gi3 toxin-insensitive Gq/11 Gs. Subtype-specific immunoprecipitation protein alpha subunits photolabeled [alpha-32P] GTP azidoanilide, in absence presence carbachol, revealed selective coupling activated...

The influence of somatostatin was studied on cyclic AMP levels and adenylate cyclase activity in cyc- variants S49 lymphoma cells. These cells are deficient the guanine nucleotide site that mediates hormone-induced stimulation, but their can be stimulated by forskolin. Somatostatin maximally decreased 30 microM forskolin-stimulated 35%. Half-maximal suppression occurred at about 0.1 nM somatostatin. (up to 1 microM) had no effect 100 membrane preparations when nucleotides were not present....

We addressed the question as to which subtypes of G protein subunits mediate activation phospholipase C-beta by muscarinic m1 receptor. used rat basophilic leukemia cell line RBL-2H3-hm1 stably transfected with human receptor cDNA. microinjected antisense oligonucleotides into nuclei cells inhibit selectively expression subunits; 48 hr later receptors were activated carbachol, and increase in free cytosolic calcium concentration ([Ca2+]i) was measured. Antisense directed against mRNA coding...
The current study aimed to achieve a bibliometric research, map and analyze publications related the organic food market. Thus, search in Web of Science database was carried out, covering period from 1945 2013. 196studies found were discussed analyzed. 20 most relevant articles comprised h -index qualitatively They indicated main themes relationships found. bigger number launched between 2006 2012 they concentrated following fields: agricultural, food, environmental business. written English...
La discusión sobre los mercados desde una dinámica centrada en el sesgo sociológico se ha fomentado últimos años, especialmente las décadas de 1970 a 1980. Considerando la relevancia estudios que discuten perspectiva sociología económica sector agroalimentario, este artículo mapeó literatura actual construcción social y calidad, través del procedimiento metodológico revisión bibliométrica. Encontramos Estados Unidos, Francia Brasil tienen influencia considerable relación con mercados. Los...
