Deep vein thrombosis (DVT) is a common type of venous thrombosis. Successful resolution of DVT-related thrombi is important in the treatment of DVT. Endothelial progenitor cells (EPCs) have emerged as a promising therapeutic choice for DVT-related thrombus resolution; however, the clinical application of EPCs faces many challenges. In the present study, the expression of miR-582, miR-195 and miR-532 under hypoxic or normoxic conditions was measured using quantitative real-time PCR analysis (qRT-PCR) and the results showed that the increased fold of miR-195 was highest in human EPCs (hEPCs) under hypoxic conditions. Then the role and regulating mechanism of miR-195 in improving the function of EPCs was investigated. To investigate the effect of miR-195 inhibition on the autophagy of hEPCs, the expression of the autophagy-related genes LC3B and beclin1 was examined using western blotting, and the formation of autophagosomes was observed using TEM. The results indicated that the inhibition of miR-195 expression could promote autophagy of hEPCs. In addition, we investigated the role of miR-195 on the proliferation, migration and angiogenesis of hEPCs under hypoxia. The results revealed that miR-195 inhibition promotes cell proliferation, migration and angiogenesis of hEPCs under hypoxia. Furthermore, GABA type A receptor associated protein like 1 (GABARAPL1) was identified as a directed target of miR-195 and GABARAPL1 silencing could decrease the effect of miR-195 knockdown on cell proliferation, migration, angiogenesis and autophagy of hEPCs under hypoxia. Together, these results indicate that miR-195 regulates cell proliferation, migration, angiogenesis and autophagy of hEPCs by targeting GABARAPL1.
