Potential therapeutic targets in the Wnt/β-catenin signaling. Numerous small molecules inhibit Wnt/β-catenin signaling at different steps of the pathway. Porcupine inhibitors prevent Wnt ligands secretion. Receptor or co-receptor inhibitors prevent the receptor actions of Wnt ligands. Inhibitors of GSK3β, axin, DVL, and CK1 interfere with Wnt/β-catenin downstream signaling. Inhibitors of TCF/LEF suppress Wnt/β-catenin-dependent gene transcription. Several natural products alleviate renal fibrosis by regulating the Wnt/β-catenin signaling pathway.
