However, lncRNA NDRG1-OT1 was reported to act as a scaffold for recruiting HIF-1α via its third-quarter fragment, rather than whole molecule, to increase the expression of the downstream gene N-myc downstream regulated gene 1 (NDRG1) in breast cancer cells under hypoxia, along with the different effects of the remaining fragments on the same target gene [156]. Here, HIF1A is linked to breast carcinoma.
