ABSTRACT
BACKGROUND:
MicroRNA-1290 (miR-1290) has been reported to be involved in many diseases and play a key role during the development process. However, the role of miR-1290 in atherosclerosis (AS) is still unclear. METHODS ANDRESULTS:
The current study showed that the expressions of miR-1290 were high in serum of patients with hyperlipidemia. The functional role of miR-1290 were then investigated in human umbilical vein endothelial cells (HUVECs). Here, we found that miR-1290 expressions were notably enhanced in HUVECs mediated by IL-8. miR-1290 inhibitor repressed monocytic THP-1 cells adhesion to HUVECs by regulating ICAM-1 and VCAM-1, inhibited proliferation through regulating cyclinD1 and PCNA, and inhibited inflammatory response by regulating IL-1ß. Mechanistically, we verified that miR-1290 mimic was able to directly target the 3'-UTR of GSK-3ß mRNA using luciferase reporter assay. Knockdown of GSK-3ß (si-GSK-3ß) promoted HUVECs adhesion and the expression of IL-1ß, and partially restore the depression effect of miR-1290 inhibitor on HUVECs adhesion and inflammation. In contrast, si-GSK-3ß inhibited the proliferation of HUVECs and the expression of cyclinD1 and PCNA.CONCLUSIONS:
In summary, our study revealed that miR-1290 promotes IL-8-mediated the adhesion of HUVECs by targeting GSK-3ß. However, GSK-3ß is not the target protein for miR-1290 to regulate the proliferation of HUVECs. Our findings may provide potential target in atherosclerosis treatment.Palavras-chave
