Uses
Apelin-13 trifluoroacetate salt has been used to determine whether apelin promotes progression of diabetic nephropathy (DN) by inducing podocyte dysfunction. It has also been used to examine the effects of apelin on myocardial infarction (MI) injury and underlying mechanisms.
Uses
The apelin gene encodes a pre-proprotein that is processed to generate bioactive peptides consisting of 36, 17, or 13 amino acids (apelin-36, apelin-17, and apelin-13, respectively). Apelin-13 is the endogenous ligand of the APJ receptor, activating this G protein-coupled receptor with an EC50 value of 0.37 nM (the EC50 values for apelin-17 and apelin-36 are 2.5 and 20 nM, respectively). It acts primarily in the periphery and central nervous system, playing important roles in regulating cardiovascular function, fluid homeostasis, hypertension, and insulin sensitivity. Unlike apelin-36, apelin-13 poorly blocks the entry of human immunodeficiency virus into cells.
Uses
An endogenous ligand of Apelin Receptor (APLNR/APJ receptor) that plays important roles in regulating fluid homeostasis, cardiovascular function, and insulin sensitivity.
Definition
ChEBI: Apelin-13 is a 13 amino acid oligopeptide which is the ligand for the apelin receptor (also known as the APJ receptor). It exhibits hypotensive and neuroprotective effects, and may be a potential prognostic biomarker for acute ischemic stroke and multiple sclerosis. It has a role as an antihypertensive agent, a biomarker, an autophagy inhibitor, a neuroprotective agent and a human metabolite. It is a conjugate base of an apelin-13(3+).
General Description
Apelin is a regulatory peptide and a ligand of the APJ receptor. It is a member of the G protein-coupled receptor family. Apelin and APJ are broadly dispersed in the body.
Biological Activity
apelin-13 is an endogenous ligand of the apj receptor.the apelin receptor apj, one of a group of g-proteincoupled receptors (gpcr), have recently been paired with their cognate peptide ligands using ‘‘reverse pharmacology’’, and functional evidence suggests a role for this receptor in the regulation of cardiovascular function, fluid homeostasis, and as a coreceptor for hiv infection.
Biochem/physiol Actions
Apelin plays physiological roles in the cytoprotection of many internal organs. It is used to treat insulin resistance and hypertension, but it may also can act as a negative factor. Apelin also regulates cardiovascular diseases.
in vitro
apelin-13 was identified as an endogenous ligand of the apj receptor, which could activate this g protein-coupled receptor with an ec50 value of 0.37 nm. in addition, the ec50 values for apelin-17 and apelin-36 have been found to be 2.5 and 20 nm, respectively [1].
in vivo
in a previous study, urethane anaesthetised, paralysed and ventilated male sd rats were used to investigate the action of apelin-13 directly microinjected into the nucleus tractus solitarius (nts) and the rostral ventrolateral medulla (rvlm) on arterial pressure and phrenic nerve activity. results showed that apelin-13 microinjections into the nts led to either apnea or decreased phrenic nerve discharge amplitude by up to 30%. in the rvlm, apelin-13 caused increase in phrenic nerve discharge amplitude depending on the exact site of injection [2].
IC 50
0.37 nm for gpcr
