摘要

miRNAs (MicroRNAs) are a class of endogenous, conserved, small non-coding RNAs which play important regulatory roles in many physiological processes. Here we sought to investigate potential involvement of miRNAs relatived with angiogenesis in HUVEC under hypoxia. Quantitative Real-time RT-PCR were performed to identical miRNA changes in hypoxic cells. miRNA210 and miRNA-126 expression increased to (4. 73±0. 55) and (5. 22±0. 71)folds respectively , while miRNA-320 expression decreased to (0. 29 ± 0. 10) folds significantly after hypoxia (P<0. 05 ). VEGF and VEGFR2 mRNA expression and proteinwere increased after hypoxia compared with control group detected by Quantitative Real-time RT-PCR , ELISA andFlow Cytometry respectively(P< 0. 05). In conclusion, our results imply that miRNAsmay be involved in targeting VEGF pathway signaling to regulate angiogenesis after hypoxia in vitro. These results provide novel insights into the angiogenesis mechanism of renal I/R injury.
