Wnt11

Wnt11 is a Wnt ligand involved in gastrulation, neurulation, cardiogenesis, nephrogenesis, and chondrogenesis during fetal development^[1]. Mechanistically, Wnt11 activates canonical and non-canonical Wnt signaling cascades depending on receptor context, including Frizzled, LRP6, ROR2, and RYK^[1]. This receptor-dependent signaling links Wnt11 to cellular movement, cardiac specification, and morphogenesis, with evidence that Wnt11 can induce cardiomyogenesis during embryonic development and in adult cells^[1][2]. In disease models, human WNT11 expression has been reported in multiple cancers, while Wnt11 downregulation in hepatocellular carcinoma and ectopic Wnt11 expression reduced proliferation and migration through PKC, β-catenin, RhoA/Rho kinase, and Rac1-related mechanisms^[1][3]. Compared with related isoforms, Wnt11 differs from prototypic canonical Wnt3a and noncanonical Wnt5a because Wnt ligands activate distinct pathways through specific coreceptor coupling and reciprocal pathway inhibition at the cell surface^[4]. For experimental applications, Wnt11 remains useful for studying noncanonical Wnt signaling, cardiomyogenic differentiation, developmental organogenesis, and tumor-cell migration models^[1][2][3].
