Zusammenfassung: | The incidence of oral cancer has recently been increasing worldwide, particularly among young individuals and women. The primary risk factors for head and neck cancers, including oral and pharyngeal cancers, are smoking, alcohol consumption, poor oral hygiene, and repeated exposure to mechanical stimuli. However, approximately one-third of the patients with oral and pharyngeal cancers are neither smokers nor drinkers, which points to the existence of other mechanisms. Recently, human microbes have been linked to various diseases, including cancer. Oral pathogens, especially periodontal pathobionts, are reported to play a role in the development of colon and other types of cancer. In this study, we employed a series of bioinformatics analyses to pinpoint
as the predominant oral bacterial species in oral and pharyngeal cancer tissue samples. We successfully isolated
from the saliva of patients with oral cancer and demonstrated that
indeed promoted oral squamous cell carcinoma development by activating YAP in a mouse tongue cancer model. Our research offers scientific evidence for the role of the oral microbiome in oral cancer progression and provides insights that would help in devising preventative strategies against oral cancer, potentially by altering oral bacterial profiles. |
