Of importance, analysis of correlation between SLC2A5 expression and patient prognosis from microarray database revealed that SLC2A5 overexpression was associated with poor prognosis in lung cancer a whole (p = 0.022) and in lung adenocarcinoma (p = 0.0062) patients, but such association did not exist in lung SCC (p = 0.31) (Fig. 1d). Here, SLC2A5 is linked to lung cancer.
