Results demonstrated that RGC32 was expressed in many LADC cell lines; the expression of NCI-H358 was the highest, followed by NCI-H1299, A549, NCI-H1975, and NCI-H460, while the expression of HCC-827, NCI-H1650, and NCI-H3255 was relatively low. This evidence concerns the gene RGCC and hepatocellular carcinoma.
