Schematic representation of targeting USP5 by WP1130 and Vialinin A for suppressing Wnt/β-catenin signaling, cancer stemness, and metastasis in lung cancer. The interaction between USP5 and β-catenin leads to the deubiquitylation of β-catenin and inhibition of proteasome-mediated degradation of β-catenin. Stabilized β-catenin then enters nucleus, activates the transcription of target genes, promotes cancer cell stemness, invasion, metastasis and tumor initiation
