Methanolic extract of Ephedra alata inhibits breast cancer cells in vitro and in vivo

Objective:To determine the anticancer potential of the methanolic extract from Ephedra alata against breast cancer both in vitro and in vivo. Methods:The effects of the methanolic extract of Ephedra alata on the viability,migration as well as apoptosis of breast cancer 4T1 cells were measured using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay,Transwell assay,and annexin V-FITC staining assay,respectively.Histological examination was also carried out.Moreover,a murine breast cancer model was established to evaluate the inhibitory effect of the extract.Biochemical parameters including hepatic and non-hepatic enzymes,malondialdehyde,and glutathione were investigated. Results:The methanolic extract of Ephedra alata showed a strong anti-proliferative and anti-migratory activity against 4T1 cells in a dose-dependent manner.It also induced apoptosis in 4T1 cells.In an in vivo mouse model,the extract markedly inhibited tumor growth,reduced malondialdehyde,and hepatic and non-hepatic enzymes as well as increased glutathione level. Conclusions:The methanolic extract of Ephedra alata inhibits breast cancer in vitro and in vivo,which may be a promising anticancer agent.
