Research Backgrounds

Function:

Endogenous ligand for the apelin receptor (APLNR). Drives internalization of the apelin receptor (By similarity). Apelin-36 dissociates more hardly than (pyroglu)apelin-13 from APLNR (By similarity). Hormone involved in the regulation of cardiac precursor cell movements during gastrulation and heart morphogenesis (By similarity). Has an inhibitory effect on cytokine production in response to T-cell receptor/CD3 cross-linking; the oral intake of apelin in the colostrum and the milk might therefore modulate immune responses in neonates (By similarity). Plays a role in early coronary blood vessels formation (By similarity). Mediates myocardial contractility in an ERK1/2-dependent manner (By similarity). May also have a role in the central control of body fluid homeostasis by influencing vasopressin release and drinking behavior (By similarity).

(Microbial infection) Endogenous ligand for the apelin receptor (APLNR), an alternative coreceptor with CD4 for HIV-1 infection. Inhibits HIV-1 entry in cells coexpressing CD4 and APLNR. Apelin-36 has a greater inhibitory activity on HIV infection than other synthetic apelin derivatives.

PTMs:

Several active peptides may be produced by proteolytic processing of the peptide precursor.

Subcellular Location:

Secreted. Secreted>Extracellular space.
Note: Abundantly secreted in the colostrum. Lower level in milk. Decreases rapidly within several days after parturition in milk, but is still detectable even in commercial milk.

Application: IF/ICC    Species: Mouse    Sample:

Figure 2 The expression of apelin in DR mice treated with LV-EGFP, LV-Apelin+, or LV-Apelin−. (A) Representative apelin staining images by CLSM and (B) the quantification of the staining intensity indicated that apelin was moderately expressed in the LV-EGFP group and was primarily distributed in the GCL, while it was widely expressed in the LV-Apelin+ group and distributed in the GCL and INL. In the LV-Apelin− group, there was almost no expression of apelin. (C) The qRT-PCR results revealed that the mRNA expression of apelin was upregulated in the LV-Apelin+ group, but downregulated in the LV-Apelin− group. Blue: DAPI, red: apelin. GCL: ganglion cell layer; INL: inner nuclear layer; ONL: outer nuclear layer. Data were expressed as mean ± SD. LV-Apelin+ versus LV-EGFP; LV-Apelin− versus LV-EGFP;

Application: IHC    Species: Human    Sample: AE samples

Figure 5. Immunohistochemical analysis of CD34, vascular endothelial growth factor (VEGF), and angiogenesis-related differentially expressed genes in the experimental (alveolar echinococcosis [AE]) and control (AE control group [AEC]) group samples. (A) CD34 and VEGF staining in AE samples showed different degrees of vascularization. Increased expression of SPP1, RSPO3, APLN, TWIST1, ADAM12, and FOXC2 was observed in the AE samples, whereas low or no expression of these genes was observed in the AEC samples. (B) The H-scores of CD34, VEGF, SPP1, RSPO3, APLN, TWIST1, ADAM12, and FOXC2 were significantly higher in the AE samples than in the AEC samples (values represent the mean ± standard error of the mean: ∗∗∗P < .001, ∗∗∗∗P < .0001).
