ГПП-1 химические свойства, назначение, производство
История
GLP-1 was first identified in the early 1980s, following the cloning of the proglucagon gene. The biological activity of GLP-1 was investigated initially by using the N-terminal extended forms of GLP-1(1–37 and 1–36 amide). However, these forms were devoid of biological activity. In the late 1980s, bioactive GLP-1 peptides were purified from gut extracts and were identified to be GLP1(7–37) and GLP-1(7–36)-amide. In the current literature, the unqualified designation of GLP-1 corresponds to the truncated peptides.
Использование
Glucagon-Like Peptide I (GLP1) has been used as an antigen in excess amounts for the incubation of primary antibodies, post-immunocytochemistry with positive results of paraffin-embedded pancreatic tissues of Rana temporaria.
Общее описание
Glucagon-Like Peptide I (GLP1) is an incretin hormone, which functions as ligand for GLP1 receptors (GLP1R). These receptors are expressed in renal and cardiovascular system, such as smooth muscle and endothelial cells.
Биохимия/физиол Действия
Glucagon-Like Peptide I (GLP1) controls the metabolism of glucose, by inducing the secretion of insulin and suppressing that of glucagon. Studies in Indonesian population show that reduced levels of this protein are linked with increased susceptibility to type 2 diabetes mellitus. Plasma levels of this hormone also show significant association with systolic and diastolic blood pressure levels.
Побочные эффекты
Common side effects of GLP-1 include: loss of appetite, nausea, vomiting, diarrhoea. Other side effects may include: dizziness, mild tachycardia or increased heart rate, infection, headache, and indigestion. Temporary mild itching and redness of the skin at the injection site may also occur. Serious and rare side effects include: pancreatitis, medullary thyroid cancer, acute (sudden) kidney injury, worsening of diabetes-related retinopathy, and severe allergic reactions. And GLP-1 agonists are recommended during pregnancy because they can cause abnormal foetal development. Seek medical attention if any serious adverse reactions occur.
