CSNK1A1 and glioma: To examine the role of Csnk1a1 in the pathogenesis of glioma, firstly, Western blotting was performed to analyse the difference in Csnk1a1 protein expression between glioma and non‐tumour brain tissue samples. Compared with normal brain tissue, Csnk1a1 was highly expressed in glioma (Figure 1A). The protein expression in tumour tissue samples was about 1.5 times as high as that of non‐tumour tissue specimens.
