%X 研究利用孟德尔随机化法(Mendelian randomization, MR)分析了几种食源性病原体与白细胞分化抗原44 (Cluster of differentiation 44, CD44)之间的关联&#65292;CD44抗原是胃肠道癌症发展和转移的标志物。该研究从综合流行病学数据库(IEU)、芬兰基因数据库(FinnGen)和英国生物数据库(UK Biobank)获得了全基因组关联研究(Genome-wide association studies, GWAS)数据&#65292;并主要使用反方差加权(Inverse-variance weighting, IVW)等统计方法分析了相关性。同时还进行了敏感性分析&#65292;以提高结果的可靠性。研究结果表明&#65292;幽门螺旋杆菌与CD44抗原呈显著正相关&#65292;而小肠结肠耶尔森氏菌与CD44抗原呈显著性负相关&#65292;因此研究判断幽门螺旋杆菌会促进癌症的发生和转移&#65292;而小肠结肠耶尔森氏菌可抑制癌细胞的发展和转移。然而&#65292;其余细菌种类没有发现明显的相关性。部分食源性致病菌可能会促进胃肠道癌症的转移&#65292;如幽门螺旋杆菌。但还有些可能抑制了癌细胞的转移&#65292;表明背后可能有更复杂的生理机制。<br>This study used Mendelian randomization (MR) to analyze the association between several foodborne pathogens and the Cluster of Differentiation 44 (CD44) antigen, a marker of gastrointestinal cancer development and metastasis. The study obtained genome-wide association studies (GWAS) data from Integrative Epidemiology Unit (IEU), FinnGen and UK Biobank and analyzed the correlation mainly using statistical methods such as inverse-variance weighted (IVW). Sensitivity analyses were also carried out to improve the reliability of the results. The results of the study showed that <i>Helicobacter pylori</i> showed a significant positive correlation with CD44 antigen; <i>Yersinia enterocolitica</i> showed a significant negative correlation with CD44 antigen; therefore, we judged that <i>Helicobacter pylori</i> promotes cancer development and metastasis, and <i>Yersinia enterocolitica</i> inhibits cancer cell development and metastasis. However, no significant correlation was found for the remaining bacterial species. Some foodborne pathogens, such as <i>Helicobacter pylori</i>, can promote the metastasis of gastrointestinal cancers. However, others can inhibit the metastasis of cancer cells, suggesting that there may be a more complex physiological mechanism involved.
