EGLN2 and breast cancer: Several lncRNAs target and regulate hypoxia-related pathways to stimulate tumor growth during the invasion and proliferation of breast cancer cells: miR-597-3p is eliminated from the hypoxia-inducible factor 2 (EglN2) of the egl-9 family [139], the inhibition of EglN2 is lessened, and LINC00662 stimulates the growth and invasion of cancer cells.
