To study the interaction between diabetes and the Wnt-PCP pathway during eye development, we analyzed embryos (E11.5-12.5) from STZ-induced diabetic Daam1+/+ females (seven dams) crossed with Daam1+/gt males, comparing them with control embryos from untreated Daam1+/+ females (four dams) crossed with Daam1+/gt males. The gene discussed is DAAM1; the disease is diabetes mellitus.
