Schematic diagram illustrating the proposed mechanism by which Axin may interfere with normal mammary gland development in DDTg mice. Side branching, which requires Wnt-4, is not significantly affected by overexpression of Axin. However, lobulo-alveolar development is severely impaired. This may be due to the reduced expression of cyclin D1, a Wnt target gene, which is required for lobulo-alveolar development. See text for references. Diagram modified from Robinson et al. (2000).
