Western blots with a panel of human non-small cell lung cancer primary tumor cell lines (H1792, A549, H1703, and H460) and the patient-derived brain-metastatic lung adenocarcinoma cell line (UW-lung-16) and primary human adenocarcinoma cell line H1792 reveal that all express GABRA5 (Figure 1B), concordant with RT-PCR analysis (Figure S1C). This evidence concerns the gene GABRA5 and neoplasm.
