A forma de comprimento total pertence à família de receptores de citocinas de Classe I. Estas são todas as proteínas com um domínio de transmembrana único em que o domínio intracelular está associado com uma proteína tirosino-quinase conhecido como JAK que, por sua vez, fosforila o STAT-quinase que inicia uma cascata de proteína de fosforização. O receptor de GH é clivado por uma enzima de metaloproteinase e a quantidade de GHBP em circulação tem sido utilizada como uma medida do receptor de GH nos casos em que se suspeita de insensibilidade a GH. A forma truncada do receptor de GH (GHRtr) também produz a GHBP em circulação e tem um efeito negativo dominante sobre a atividade da forma de comprimento total. Assim, pacientes com predominantemente GHRtr são GH insensíveis, mas têm que circular GHBP.
PS: ATÉ O MOMENTO NÃO EXISTE NENHUM TIPO DE GH – HORMÔNIO DE CRESCIMENTO EM FORMA DE UTILIZAÇÃO VIA ORAL EFICIENTE, APESAR DE SER PROPALADO NA MÍDIA DE UM MODO GERAL, EM NENHUM PAÍS, POIS A INGESTÃO DO GH – É BARRADO E DISTRUÍDO PELO SUCO GÁSTRICO E SUA UTILIZAÇÃO POR LEIGOS OU PROFISSIONAIS NESTA FORMA DE UTILIZAÇÃO É CONSIDERADO UM ERRO TÉCNICO. A ÚNICA FORMA CORRETA DE UTILIZAÇÃO E A INJETÁVEL DE FORMA INTRAMUSCULAR OU SUBCUTÂNEA, POIS É UM PRODUTO BIOLÓGICO, E NÃO SÃO TODOS OS PRODUTOS BIOLÓGICOS QUE PODEM SER UTILIZADOS VIA ORAL, POIS MUITOS ACABARÃO SENDO BIODEGRADÁVEIS.
GROW: CHILD, JUVENILE AND YOUTH - SHARES OF GROWTH HORMONE AND GROWTH FACTORS LIKE INSULIN.
TO ILLUSTRATING THE IMPORTANCE OF GH ON GROWTH AND DEVELOPMENT AFTER CHRISTMAS, BUT BEYOND GROWTH, THIS HORMONE HAS OTHER IMPORTANT METABOLIC FUNCTIONS. IT IS A HORMONE WITH WIDESPREAD ANABOLIC ACTIONS, MANY OF WHICH ARE MEDIATED THROUGH PRODUCTION
GROWTH FACTORS LIKE INSULIN, IGF-1 AND IGF-2, WHICH ARE SYNTHESIZED IN THE LIVER AND TARGET TISSUES. PHYSIOLOGY-ENDOCRINOLOGY-NEUROENDOCRINOLOGY-GENETICS-ENDÓCRINO- PEDIATRICS (SUBDIVISION OF ENDOCRINOLOGY): DR. JOÃO SANTOS CAIO JR. ET DRA. HENRIQUETA VERLANGIERI CAIO.
Its effect is more profound in linear growth by stimulating the proliferation of cartilage at the epiphyseal plates of long bones, before merging. In addition to stimulating linear growth, GH also increases total bone mass and mineral content by increased activity and, probably, the number of bone modeling units. GH increases lean body mass, decreases adiposity by their lipolytic effect and increases in size and function of the body, the latter effect as IGF-mediated bone. The normal concentrations of GH are also required to maintain the function of the normal pancreatic islet. Thus, in GH secretion of insulin decreases as excess GH deficiency in reduces the absorption of glucose dependent insulin, resulting in increased insulin secretion to compensate for GH induced hormone resistance growth. Overall, the GH is a diabetogenic hormone when taken without indication and pre-disposed patients, not to be confused with disabilities and pressing need or excess. The main actions of growth hormone: GH has a direct action on the liver, adipose tissue and muscle, although many of its actions are mediated by increased synthesis and release of insulin-like growth (IGF) factors. These stimulate DNA, RNA and proteins. The average life of GH in the circulation is around 20 minutes. It circulates in various ways that vary according to the size (molecular weight of 20. 000 and 22.000) and isoelectric point (acid forms) oligomers (up to pentamers) and fragments (molecular weights 12.000 and 16.000). Moreover, approximately 50% is bound to the extracellular domain of its receptor (also known as protein binding GHBP GH). There are two GH receptor molecules, full-length and truncated forms. The full-length form belongs to the family of cytokines of Class I.
These receptors are all proteins with a single transmembrane domain in the intracellular domain is associated with a tyrosine kinase known as JAK protein that, in turn, phosphorylates STAT kinase that initiates a cascade of protein phosphorylation. The GH receptor is cleaved by a matrix metalloproteinase enzyme and the amount of circulating GHBP has been used as a measure of GH receptor in cases where it is suspected GH insensitivity. The truncated form of the GH receptor (GHRtr) also produces circulating GHBP and has a dominant negative effect on the activity of the full-length form. Thus, patients with predominantly GHRtr are GH insensitive, but have circulating GHBP.
PS: TO DATE THERE ANY KIND OF GH IN FORM OF USE ORAL EFFICIENT, DESPITE BEING IN THE MEDIA NOISED IN GENERAL, IN ANY COUNTRY OR THE INTAKE OF GH AND BARRED IS DESTROYED BY GASTRIC JUICE AND THEIR USE FOR LAY OR PROFESSIONAL USE THIS FORM IS CONSIDERED A TECHNICAL ERROR. THE ONLY CORRECT WAY TO USE IS INJECTION OF INTRAMUSCULAR OR SUBCUTANEOUS FORM, BECAUSE IT IS A BIOLOGICAL PRODUCT, AND ARE NOT ALL ORGANIC PRODUCTS THAT CAN BE USED ORAL, THAT WILL EVENTUALLY BE BIODEGRADABLE.
