Miracle drink supplemented with Lactobacillus bulgaricus loaded-chitosan/alginate nanoparticles as a medicinal food for control of MCF7 cancer cells

Background: Cancer continues to be one of the greatest challenges in modern medicine and is second only to cardiovascular disease as the main cause of death. Breast cancer in particular is responsible for 15% of deaths in women. In this study, Lactobacillus bulgaricus was microencapsulated using a chitosan/alginate mixture. Parameters such as chitosan, alginate, and L. bulgaricus populations were optimized using Design Expert software. The responses were loading efficiency, particle size, release, and ζ-potential. Subsequently, the cytotoxicity of the optimized ratio of chitosan/alginate nanoparticles was investigated on MCF-7 cancer cells. Results: The research revealed that optimal conditions for the mentioned variables were a chitosan concentration of 1% w/w, an alginate concentration of 1% w/w, and a L. bulgaricus count of 8.15 CFU/ml. Following numerical optimization, the loading efficacy = 91.15%, the release = 71.55%, the polydispersity index = 0.11, and the ζ-potential = 61.94 based on numerical optimization. Findings revealed that miracle drinks with L. bulgaricus-loaded chitosan/alginate microcapsule ratios exhibited toxic and potential apoptotic effects on MCF-7 cancer cells. This study showed that a miracle drink prepared with the optimal ratio of probiotic nanoparticles stops cells in the S and G2/M phases. Conclusions: The results show that Miracle drink supplemented with L. bulgaricus loaded-chitosan/alginate nanoparticles has a toxic and lethal effect on MCF-7 cancer cells. This compound can be suggested and used as an alternative candidate or complementary cancer therapy.How to cite: Jovaini K, Mortazavian Farsani SAM, Aghaee-Bakhtiari SH, et al.
