HIF1A and lung cancer: Similarly, HIF1α ( dark blue node) expression is regulated by several miRNAs including miR-17-92 in lung cancer cells [101], miR-519c and miR-18a in breast and lung cancer cells [102], [103], miR-22 in colon cancer cells [104], miR-199a in non-small cell lung cancers [105] and miR-429 in human endothelial cells [106].
