To 1, the fold differences in Muc5B and Muc5AC expression inside the antrum were 6.02 two.27 for ASB1.4and 5.68 two.81 for SS1-infected mice. The fold variations in Muc5B and Muc5AC expression within the fundus had been two.88 1.63 and three.84 1.53 for ASB1.4- and SS1-infected animals, respectively. Alterations in mucin mRNA expression had been also evaluated inside the duodenum. The mRNA expression levels of Muc1 were significantly improved at four weeks postinfection in the duodenum of H. heilmannii-infected mice (P 0.036) and H. pylori-infected mice (P 0.047) (see Fig. S1E within the supplemental material). Significantly improved expression of Muc5AC was seen at 4 (P 0.032) and 16 (P 0.026) weeks postinfection inside the duodenum of H. heilmannii-infected mice (see Fig. S1F).

Beneath healthy circumstances, this cell surface mucin is mainly expressed inside the glycocalyx of enterocytes and goblet cells within the smaller and massive intestine, specifically at the luminal surface (21).

Expression levels of Muc6 inside the antrum (A) and fundus (B) of the stomach of ASB1.4- and SS1-infected BALB/c mice are shown. Information are presented as fold adjustments in gene expression normalized to 3 reference genes and relative towards the results for the negative-control group, which are set as 1. Data obtained in the time points 1 day, 4 days, and 1, two, 3, four, and 9 weeks are pooled and designated “early stage of infection.” Information obtained in the time points 12, 16, 20, and 24 weeks are pooled and designated “mid-stage of infection.” Information obtained in the time points 34 and 52 weeks are pooled and designated “late stage of infection.” Information are shown as suggests regular deviations.
