Our study previously showed the involvement of Notch1 in Th1 differentiation in H. pylori-infected patients. However, the role of Notch1 in Th17 or Treg differentiation during H. pylori infection and the potential diagnostic value of its associated genes remain unclear. Here, we found that NOTCH1 was positively correlated with Th17-related genes RORγt (r = 0.616, p < 0.001) and IL17F (r = 0.523, p < 0.01), but not with Treg-related genes FOXP3 and IL10. The mRNA levels of aforementioned genes were upregulated at different stages of mucosal injury except for upper gastrointestinal ulcers. A combiROC analysis of NOTCH1 and IL17F discriminated H. pylori-infected gastritis from healthy controls with high accuracy (AUC of 0.952, sensitivity of 0.929, and specificity of 0.893). This study is the first to show that Notch1 is correlated with Th17-associated gene expression during H. pylori infection. Additionally, NOTCH1 and IL17F are potential diagnostic markers.
