Epigenetic inheritances can be passed among host generations, regulated by gut microbiome. Several factors can cause dysbiosis, characterized by changes in microbiome diversity, related to initiation and promotion of chronic inflammatory pathways, promotion of genetic and epigenetic alterations, leading to tumor origin and development, as in breast and colorectal cancer. Nevertheless, probiotic bacteria, as Lactobacillus and Bifidobacterium, can induce specific mechanisms against various infections, including diverse types of cancer, through apoptosis, antioxidant activity, immune response induction, and epigenetics regulation.
