Expression pattern of CAMKK2 in WHO grade II–IV gliomas. (A) CAMKK2 was differently expressed between LGG and HGG samples in CGGA mRNA expression microarray data (t‐test, P < 0.0001). (B) Representative CAMKK2 staining results by IHC. CAMKK2 showed a higher expression in higher‐grade samples. (C) Statistical result of CAMKK2 IHC staining. CAMKK2 showed a higher expression in HGG samples (chi‐square test, P < 0.0001). LGG, low‐grade glioma (WHO grade II); HGG, high‐grade glioma (WHO grade III–IV); N, normal brain tissue; II, WHO grade II; III, WHO grade III; IV, WHO grade IV.
