Product Information:

MSAB is a selective inhibitor of Wnt/β-catenin signaling. MSAB shows potent anti-tumor effects selectively on Wnt-dependent cancer cells in vitro and in mouse cancer models. MSAB binds to β-catenin, promoting its degradation, and specifically downregulates Wnt/β-catenin target genes.

In Vitro:

MSAB (2-10 μM) selectively decreases cell viability of Wnt-dependent cells while showing little effect on Wnt-independent cells and normal human cells.

MSAB (0.01-10 μM; 20 h) inhibits T-cell factor (TCF) luciferase reporter activity in HCT116 cells.

MSAB (20 h) suppresses the Wnt3a-induced TOP-Luc activation and increases of active β-catenin levels in HEK293T cells.

MSAB (0.5-10 μM; 20 h) decreases mRNA and protein levels of endogenous Wnt target genes in HCT116 cells.

MSAB (5 μM; 16 h) induces degradation of β-catenin in a proteasome-dependent manner in HCT116 cells.

 

In Vivo:

MSAB (10-20 mg/kg; i.p. daily for 2 weeks) inhibits tumor growth of Wnt-dependent cancer cells in mouse xenograft model.

MSAB (10-20 mg/kg; i.p. twice daily for 2 weeks) inhibits tumor growth of MMTV-Wnt1 transgenic mice.
