Fig. 1From: A novel circ_MACF1/miR-942-5p/TGFBR2 axis regulates the functional behaviors and drug sensitivity in gefitinib-resistant non-small cell lung cancer cellsCirc_MACF1 expression is decreased in A549/GR and PC9/GR cells. A, B MTT assay of cell viability and the IC50 values for gefitinib in A549/GR, A549, PC9/GR, and PC9 cells. C qRT-PCR analysis of circ_MACF1 expression in A549/GR, A549, PC9/GR, and PC9 cells. D, E Subcellular fractionation assay showing the subcellular localization of circ_MACF1 in A549/GR and PC9/GR cells. F, G RNase R assay showing the RNase R resistance of circ_MACF1 in A549/GR and PC9/GR cells. *P < 0.05Back to article page
