“…Those bacteria produce and release enzymes that deconstruct the extra-cellular matrix components including collagen, process that results in production of substrates that enhance tissue invasion [80]. Those bacterial enzymes, endotoxins, and metabolic by products are toxic to tissues, may cause direct damage to neighboring epithelial cells DNA, and they can induce mutations in protooncogenes and tumor suppressor genes, or cause alterations in molecular signaling pathways implicated in cell survival, proliferation or differentiation [79]. Oral bacteria may promote carcinogenesis by constitutively activating toll-like receptors, such as toll-like receptor 5 (TLR5) [80].…”

“…The subgingival biofilms in periodontitis act as gram-negative anaerobic bacteria reservoirs of P. gingivalis and A. actinomycetemcomitans [142], that release enzymes and invade to gingival epithelial cells [143]. Those enzymes and other bacterial components such as endotoxins, and metabolic by-products that are toxic to tissues, may cause direct damage to DNA of the surrounding epithelial cells, or are able to induce mutations in proto-oncogenes and tumor suppressor genes, or interfere with the molecular signaling pathways involved in cell survival and/or proliferation [144]. P. gingivalisis a periopathogenic bacterium that mediates the local inflammatory response of periodontitis [145], interferes with physiological metabolism, invades gingival epithelial cells, and inhibits apoptosis [146], that is a cancer hallmark [147].…”

“…As bactérias causadoras da DP, seus componentes, como endotoxina, e seus subprodutos metabólicos podem causar toxicidade nas células circundantes e desencadear mutações em proto-oncogenes e genes supressores de tumores, por consequência alterar vias de sinalizações envolvidas no mecanismo de proliferação celular 23 . o Porphyromonas gingivalis A P. gingivalis é uma bactéria que coloniza a cavidade oral, sendo encontrada principalmente na placa supragengival.…”
