S100A8 and infection: However, a positive association was observed between overexpression of ANXA1 and female gender in the GA group, since in women the mRNA expression was twice as high as in men (mean RQ = 6.67 versus 3.25), and the H. pylori-cagA+ infection showed an mRNA mean level approximately twice higher in patients infected by cagA+ strains (mean RQ = 6.40 versus mean RQ = 2.77).
