The partially purified cell-secreted proteins of this strain (hereafter referred to as Lb-PPSPs) showed a time and dose-dependent anti-cancer and apoptosis induction function. There was a remarkable decline in the survival rate of MCF-7 cells at doses equal to and higher than 0.5 mg/mL after 48 h. The changes in expression of the three genes involved in the apoptosis pathway (BAX, BCL-2, and BCL2L11) in MCF-7 cells treated with the Lb-PPSPs confirm its cytotoxic activity and apoptosis induction.
