The results obtained indicate that lactic acid probiotic bacteria B. animalis and L. rhamnosus significantly inhibit the migratory and invasive activity of MCF-7 and MDA-MB-231 cells. In BC cells, when co-cultured with B. animalis, a significant increase in the expression of the signaling molecule STAT-6 and the glucose transporter GLUT-1 is observed. The increase in the expression of these proteins indicates a rise in the absorption and metabolism of glucose via the glycolytic pathway. It was shown that in BC cells characterized by a low degree of malignancy and in which a high insulin receptor (IR) expression is associated with a poor prognosis, bifidobacteria caused a decrease in the expression of IR, and in BC cells of medium and high degree of malignancy, on the contrary, an increase in the IR expression was noted, which may lead to a decrease in the insulin resistance of these cells. Studies of the complex effect of the B. subtilis metabolite IMV B-7724 and B. animalis on the antitumor immune response of mice with solid Ehrlich adenocarcinoma revealed that in animals of this group there is an increase in the functional activity of NK cells, cytotoxic T lymphocytes, and macrophages of the M1 and M2 types.   Product Description popup.authors Bezdieniezhnykh Nataliia O.
