GALNT6 and neoplasm: To examine the role of GALNT6 in the EMT progression of lung adenocarcinoma, firstly, we measured its expression in non-tumor bronchial epithelial BEAS-2B and different lung adenocarcinoma cells, the result showed that higher levels of GALNT6 proteins were in NCI-H1975, SPCA-1 and PC9 tumor cells, but low levels were in BEAS-2B, lung adenocarcinoma A549, NCI-H1299 and NCI-H522 cells (Supplementary Fig. 1A).
