Effects of Lactobacillus acidophilus KLDS1.0901 on proliferation and apoptosis of colon cancer cells

Colon cancer is the most common type of malignant tumor. The cytotoxicity effect of Lactic Acid Bacteria (LAB) may be active by inhibiting cancer cell proliferation, producing anti-cancer compounds, and inducing apoptosis in cancer cells, but the mechanism is unclear. Our previous study revealed that L. acidophilus KLDS1.0901 has good probiotic properties. In this study, We screened out the highest inhibition rate of L. acidophilus KLDS1.0901 and assessed the effects on the proliferation of HT-29, Caco-2, and IEC-6 cells. Then, the apoptosis mechanism of HT-29 cells was studied when treated with L. acidophilus KLDS1.0901.
