It is well documented that hypoxia activates the hypoxia-inducible factor 1-alpha (HIF1 alpha)/vascular endothelial growth factor A (VEGFA) axis to promote angiogenesis in breast cancer. However, it is unclear how this axis is negatively regulated. In this study, we demonstrated that miR-153 directly inhibits expression of HIF1 alpha by binding to the 3'UTR of HIF1A mRNA, as well as suppresses tube formation of primary human umbilical vein endothelial cells (HUVECs) and breast cancer angiogenesis by decreasing the secretion of VEGFA. Importantly, expression of miR-153 was induced by hypoxiastimulated ER stress, which activates IRE1 alpha and its downstream transcription factor X-box binding protein 1 (XBP1). X-box binding protein 1 directly binds to the promoter of the miR-153 host gene PTPRN and activates transcription. These results indicate that hypoxia induces miR-153 to fine tune the HIF1 alpha/VEGFA axis in breast cancer angiogenesis and miR-153 could be used for breast cancer anti-angiogenesis therapy.
