Based on previously published studies and our current findings, we herein present schematic illustrations of the hypothetical role of DKK3 in glioma progression considering its interaction with CTNNB1, FSTL1, and CSNK1A1, which are involved in the Wnt/β-catenin signaling pathway (Fig. 5). This evidence concerns the gene CSNK1A1 and glioma.
