HIF-1α promotes JMJD2B oncoprotein transcription in colorectal cancer-derived tumor cells, triggering a significant increase in cell proliferation and invasion through the overexpression of SLC2A1, SLC2A3, ELF3, UCA1, MET, NOV by removing trimethylation of H3K9 on their promoters [39]. Here, HIF1A is linked to colorectal cancer.
