Abstract

Objectives: Porphyromonas gingivalis (P. gingivalis) is a keystone periodontal pathogen associated with various gastro-intestinal tract cancers. However, whether P. gingivalis can promote oral squamous cell carcinoma (OSCC) and the underlying mechanism associated with such promotion remain unclear.

Materials and methods: In this study, OSCC xenograft models were used to evaluate the effects of P. gingivalis on tumor progression. The functional studies were done on several OSCC cell lines in vitro. P. gingivalis-specific 16S rRNA fluorescent in situ hybridization (FISH) was used to test its prevalence in clinical samples.

Results: We found that P. gingivalis increased tumor volume and tumor growth in OSCC nude models. Functional studies demonstrated that P. gingivalis inhibited the apoptosis of OSCC cells by promoting cellular autophagy. P. gingivalis was more prevalent in FISH samples from patients with OSCC than from patients with leukoplakia or healthy subjects (70% vs. 47.2% vs. 33.3%, p = 0.045 and p < 0.001, respectively).

Conclusion: These data suggest that P. gingivalis plays an accelerating role in OSCC progression and contributes to OSCC by enhancing the autophagy pathway to reduce carcinoma apoptosis.

牙龈卟啉单胞菌通过调节自噬促进口腔鳞状细胞癌的发展

目的：牙龈卟啉单胞菌（P：牙龈卟啉单胞菌（P. gingivalis）是一种与多种胃肠道癌症相关的关键牙周病原体。然而，牙龈卟啉单胞菌是否能促进口腔鳞状细胞癌（OSCC）的发生以及与之相关的潜在机制仍不清楚：本研究使用 OSCC 异种移植模型来评估牙龈脓毒性杆菌对肿瘤进展的影响。在体外对几种 OSCC 细胞系进行了功能研究。利用牙龈脓杆菌特异性 16S rRNA 荧光原位杂交（FISH）检测其在临床样本中的流行情况：结果：我们发现，在 OSCC 裸鼠模型中，牙龈球菌会增加肿瘤体积和肿瘤生长。功能研究表明，牙龈脓毒性杆菌通过促进细胞自噬抑制了 OSCC 细胞的凋亡。在 OSCC 患者的 FISH 样本中，牙龈脓疱病菌的流行率高于白斑病患者或健康人（70% vs. 47.2% vs. 33.3%，p = 0.045 和 p 结论：这些数据表明，牙龈脓疱病菌在 OSCC 患者中的流行率高于白斑病患者或健康人：这些数据表明，牙龈脓疱疮杆菌在 OSCC 的发展过程中起着加速作用，并通过增强自噬途径减少癌细胞凋亡来促进 OSCC 的发展。

期刊介绍： Oral Diseases is a multidisciplinary and international journal with a focus on head and neck disorders, edited by leaders in the field, Professor Giovanni Lodi (Editor-in-Chief, Milan, Italy), Professor Stefano Petti (Deputy Editor, Rome, Italy) and Associate Professor Gulshan Sunavala-Dossabhoy (Deputy Editor, Shreveport, LA, USA). The journal is pre-eminent in oral medicine. Oral Diseases specifically strives to link often-isolated areas of dentistry and medicine through broad-based scholarship that includes well-designed and controlled clinical research, analytical epidemiology, and the translation of basic science in pre-clinical studies. The journal typically publishes articles relevant to many related medical specialties including especially dermatology, gastroenterology, hematology, immunology, infectious diseases, neuropsychiatry, oncology and otolaryngology. The essential requirement is that all submitted research is hypothesis-driven, with significant positive and negative results both welcomed. Equal publication emphasis is placed on etiology, pathogenesis, diagnosis, prevention and treatment.
