Bacteria and Cancer

Early Detection of Colon Cancer Following Incidental Finding of Clostridium septicum Bacteremia


Fusobacterium nucleatum in colorectal carcinoma tissue and patient prognosis​

"The amount of F. nucleatum DNA in colorectal cancer tissue is associated with shorter survival, and may potentially serve as a prognostic biomarker. Our data may have implications in developing cancer prevention and treatment strategies through targeting GI microflora by diet, probiotics and antibiotics."


Modulation of p53 during bacterial infections


"In recent years, numerous bacterial pathogens have been shown to inactivate the major tumour suppressor p53 during infection. This inactivation impedes the protective response of the host cell to the genotoxicity that often results from bacterial infection. Moreover, a new aspect of the antibacterial activity of p53 that has recently come to light - downregulation of host cell metabolism to interfere with intracellular bacterial replication - has further highlighted the crucial role of p53 in host-pathogen interactions, as host cell metabolism is relevant for all intracellular bacteria, as well as other pathogens that replicate inside host cells and use host metabolites."



Oral bacteria in pancreatic cancer: mutagenesis of the p53 tumour suppressor gene

"Orodigestive cancers are frequently seen in patients with periodontitis. These findings suggest that this type of cancer may have some bacterial origins. This study hypothesizes that the peptidyl arginine deaminase (PAD) enzymes found in oral bacteria may be responsible for the p53 point mutations that occur in patients with pancreatic cancer."
