Importance of H. pylori plasticity region in cell cycle analysis of AGS cells. a Cell cycle analysis of AGS cells i worked as control) co-cultured with different genotypic variant i.e. ii cagA(+)vacA(+)P(+); iii cagA(−)vacA(−)P(+) and iv cagA(−)vacA(−)P(−). H. pylori strains for 24 h (MOI is 100), stained with propidium iodide, processed and analysed by flow cytometry. These figures are representative profile of at least three experiments. b Graphical representation of  % apoptotic cells (Sub G0 phase) infected with same group of strains were expressed as mean ± SEM. vacA positive and negative denote the vacA s1m1 and vacA s2m2 alleles, respectively
