Fermented milk supplemented with water-soluble curcumin ameliorates survival rate, selected biochemical parameters and fecal microbiota of Ehrlich ascites carcinoma-bearing mice

Abstract

AbstractThis study assessed the impact of fermented cow and soy milk supplemented with curcumin on enhancement the health status of female Swiss mice under Ehrlich ascites carcinoma (EAC) condition. Both types of milk were fermented by Lactobacillus plantarum EMCC 1027. Ninety-five grams of basal diet mixed with five grams of either fermented cow or soy milk supplemented with curcumin. Induction of Ehrlich tumor-bearing mice synergized by intraperitoneal injection with 1 × 106 Ehrlich ascites tumor cells after one week of the adaptation period. Our results showed that levels of survival rate were increased to 117% in mice that were fed fermented cow and soy milk while supplementation of fermented soy milk with curcumin improved the survival rate to 150%. The concentration of glutathione and superoxide dismutase in Ehrlich tumor-bearing was increased after feeding with both types of fermented milk. Fermented soy milk supplemented with curcumin showed the highest reduction levels of plasma tumor necrosis factor (TNF)-α and interleukin-6. The relative gene expression TNF-α was also significantly (P < 0.05) down-regulated in mice that were fed fermented soy milk with curcumin. The viable count of lactobacilli and bifidobacteria in feces samples was increased when mice fed both types of fermented milk. Dietary feeding with fermented cow or soy milk supplemented with curcumin has an ameliorative impact on the survival rate, antioxidant capacity, inflammation, fecal microbiota in EAC mouse model. Further research is still needed to investigate the molecular mechanisms in this tumor.
