S100A8 and infection: qRT-PCR results showed a similar expression of 16S rRNA and cagA in infection-III and -IV in comparison to infection-I and -II under both sh-C and sh-G transfection conditions and in abovementioned infection models, unlike in infection-III of sh-G, where we recorded the significantly decreased expression of cagA in comparison to infection-I (Fig. 8C and D).
