Summary of functions of Wnt-Foxj1a signaling in LR pattern formation. Wnt/β-catenin signaling regulates Foxj1a expression in KV via Lef1 and Tcf7 binding to the foxj1a regulatory sequence. The Wnt-Foxj1a axis appears to regulate LR asymmetry via at least two mechanisms: the first involves cilia outgrowth that is dependent on the canonical function of Foxj1a in cilia formation, and the second involves expression of charon that requires non-ciliary function of Foxj1a. Yellow highlighting indicates novel discoveries of the study.
