Retracted: Long noncoding RNA Alu‐mediated p21 transcriptional regulator promotes proliferation, migration, and pipe‐formation of human microvascular endothelial cells by sponging miR‐126

Peripheral artery disease (PAD) is a serious hazard to the elderly in the lower extremity atherosclerotic plaque, accompanied by a large number of angiogenesis. Long noncoding RNA Alu‐mediated p21 transcriptional regulator (APTR) exerts important functions in promoting cell growth. Therefore, we planned to research the mechanism of APTR in angiogenesis in PAD. CCK‐8 assay, flow cytometry analysis, and migration assay were to detect cell...
