Further exploration of the correlation between NOX4 expression and patient outcomes indicated a consistent association between high NOX4 expression and poorer prognosis across several cancer types, including GBMLGG, LGG, MESO, ACC, STAD, COAD, COADREAD, STES, PAAD, LUAD, WT, and BLCA (Figure 2A). Here, NOX4 is linked to cancer.
