How to use

In Vitro:

EW-7197 Hydrochloride (10-1000 nM; 30 minutes; 4T1 cells) treatment blocks the TGFβ-induced phosphorylation of Smad2 or Smad3 in a dose-dependent manner in 4T1 cells. EW-7197 Hydrochloride suppresses the TGFβ-induced nuclear translocation of Smad2/3 in 4T1 cells and MCF10A cells. The IC50 value of EW-7197 Hydrochloride on pSmad3 in 4T1 cells is 10-30 nM. EW-7197 Hydrochloride abrogates TGFb1-induced tumor cell migration and invasion. TGFβ1 downregulated the mRNA level of CDH1 and upregulated the mRNA levels of FN1, HMGA2 (high-mobility group AT-hook 2), SNAI1, and SNAI2 (Snail family zinc finger 1 and 2, respectively). Moreover, EW-7197 Hydrochloride abolishes the TGFβ1-induced effects on genes related to epithelial-to-mesenchymal transition (EMT).

In Vivo:

EW-7197 Hydrochloride (40 mg/kg; intraperitoneal injection; every other day; for 10 weeks; MMTV/c-Neu female mice) treatment inhibits Smad/TGFβ signaling, cell migration, invasion, and lung metastasis in MMTV/c-Neu mice. EW-7197 Hydrochloride also inhibits the epithelial-to-mesenchymal transition (EMT) in both TGFβ-treated breast cancer cells and 4T1 orthotopic-grafted mice. Furthermore, EW-7197 Hydrochloride enhances cytotoxic T lymphocyte activity in 4T1 orthotopic-grafted mice and increased the survival time of 4T1-Luc and 4T1 breast tumor-bearing mice.
