Fig. 4From: The novel circ_0028171/miR-218-5p/IKBKB axis promotes osteosarcoma cancer progression IKBKB is identified as a direct target of miR-218-5p in OS cells. a IKBKB expression level in 20 paired OS tissues. b miR-218-5p and IKBKB expression was tested by Pearson’s correlation. c, d The influence of miR-218-5p on IKBKB were analyzed by qRT-PCR and western blotting. e The miR-218-5p-binding sites in IKBKB sequence were predicted. f The relative luciferase activity was detected after co-transfection with IKBKB reporter plasmid and miR-218-5p in MG-63 and 143B cellsBack to article page
