Candidalysin has been isolated initially from a pathogenic human fungus. The extent of cell elongation 1 ( ECE1 ) gene codes for candidalysin of Candida albicans (C. albicans) . This toxin is most important for epithelial immune activation, invasiveness and infection of the oral mucosa.
This study is aimed at detecting the ECE 1 gene in C. albicans isolates from oral squamous cell carcinoma (OSCC) and oral potentially malignant disorders (OPMDs).
A total of 60 C. albicans isolates from OSCC (n = 23), OPMDs (n = 23) and healthy subjects (n = 14) were subjected to a polymerase chain reaction (PCR) for the detection of ECE 1 gene. A high prevalence of the ECE 1 gene was observed among the C . albicans isolates from OSCC and OPMD compared to the isolates from healthy subjects. Statistical significance was observed for both OSCC and OPMD groups compared to the healthy group.
The results suggest the significant role of candidalysin in oral oncogenesis. The high odds and risk ratio specify a strong association between candidalysin and these conditions. Screening this gene in a large number of isolates would further reinforce their role in oncogenesis. Future studies in characterizing their virulence on normal cell lines would clarify the importance of candidalysin in promoting oncogenesis.
念珠菌溶素最初是从一种致病性人类真菌中分离出来的。细胞延伸1(ECE1)基因编码白色念珠菌(白色假丝酵母)的念珠菌溶素。这种毒素对于上皮免疫激活、口腔黏膜的侵袭性和感染最为重要。
本研究旨在检测口腔鳞状细胞癌(OSCC)和口腔潜在恶性疾病(OPMD)的白色念珠菌分离株中的ECE1基因。
对总共60株来自OSCC(n = 23)、OPMD(n = 23)和健康受试者(n = 14)的白色念珠菌分离株进行聚合酶链反应(PCR)以检测ECE1基因。与来自健康受试者的分离株相比,在来自OSCC和OPMD的白色念珠菌分离株中观察到ECE1基因的高流行率。与健康组相比,OSCC和OPMD组均观察到统计学意义。
结果表明念珠菌溶素在口腔肿瘤发生中起重要作用。高优势比和风险比表明念珠菌溶素与这些疾病之间存在强关联。在大量分离株中筛选该基因将进一步加强它们在肿瘤发生中的作用。未来关于其对正常细胞系毒力特征的研究将阐明念珠菌溶素在促进肿瘤发生中的重要性。
