GIRK3 expression in NSCLC cell lines and in normal cells. Top panel: GIRK3 was expressed in normal human SAEC and hamster PNEC as well as being expressed in all NSCLC cell lines tested. These NSCLC cell lines are: A549, H727, H226, H520, and H2170. Bottom panel: Cyclophilin, used as a positive reaction control was seen in all samples. For all gene expression experiments, negative control reactions were performed and found to be negative. The bands on the agarose gels were consistent with the expected sizes: GIRK3-317 bp; cyclophilin-216 bp; M-100 bp.
