SLC2A5 and neoplasm: Tumor immunoassay resource (TIMER) database was used to further investigate the association between SLC2A5 expression levels and immune cell infiltration, different immune cell subsets markers in LUAD, and the UALCAN database was used to analyze the promoter methylation level of SLC2A5 in LUAD and the correlation between SLC2A5 expression level and different subgroups of LUAD patients.
