Moreover, the GSE166720 dataset, which classified 53 early-stage lung adenocarcinomas into indolent (AIS and MIA) and invasive tumours (IAC) according to pathological grade, showed that B4GALT1 mRNA expressions were higher in invasive tumours than in indolent tumours (Fig. 1F). The gene discussed is B4GALT1; the disease is neoplasm.
