- Syndecan-1 is required for Wnt-1-induced mammary tumorigenesis in miceC M Alexander
Division of Newborn Medicine, Childrens Hospital, Enders 950, Boston, Massachusetts, USA
Nat Genet 25:329-32. 2000..Our results provide both genetic and biochemical evidence that syndecan-1 can modulate Wnt signalling, and is critical for Wnt-1-induced tumorigenesis of the mouse mammary gland...
