DDX3X and posterior cortical atrophy: Through sponge effects, upregulated SNHG7 positively regulates WNT2B, while downregulation of SNHG7 inhibits EMT in PCa, further suppressing cell proliferation, invasion, and metastasis [120]; lncRNA TMPO-AS1 acts as a scaffold to enhance the interaction between CSNK2A1 and DDX3X and activates the Wnt/β-catenin signaling pathway, thereby promoting the bone metastasis of PCa [127].
