To further confirm whether the level of ALKBH7 was related to the better overall survival (OS) in HNSC, the univariate Cox regression of ALKBH7 for OS in pan-cancers was performed and the result showed that the highly expressed ALKBH7 indicated a satisfactory prognosis in KIPAN, KIRP, PAAD, HNSC, CESCN, and BLCA (Figure 1I). Here, ALKBH7 is linked to cancer.
