Abstract excerpt
Wnt antagonist Dkk1 is a negative regulator of bone formation and Dkk1 +/- heterozygous mice display a high bone mass phenotype. Complete loss of Dkk1 function disrupts embryonic head development. Homozygous Dkk1 -/- mice that were heterozygous for Wnt3 loss of function mutation (termed Dkk1 KO) are viable and allowed studying the effects of homozygous inactivation of Dkk1 on bone formation. Dkk1 KO mice showed a...
