Effect of Helicobacter pylori infection on expressions of Bcl-2 family members in gastric adenocarcinoma

Table 1 Effect of H pylori infection on expression of Bid

		Adenocarcinoma	Resection margin
H pylori (-)		0.304 ± 0.113	0.377 ± 0.119
H pylori (+)	cagA (-)	0.422 ± 0.149a	0.686 ± 0.285a
	cagA (+)	0.855 ± 0.305ac	0.939 ± 0.383ac

^aP < 0.05, vs H pylori negative group,

^cP < 0.05, vs cagA^-H pylori infection group.

Table 2 Effect of H pylori infection on expression of Bax

		Adenocarcinoma	Resection margin
H pylori (-)		0.309 ± 0.123	0.353 ± 0.139
H pylori (+)	cagA (-)	0.650 ± 0.393a	0.645 ± 0.327a
	cagA (+)	0.979 ± 0.375ac	1.001 ± 0.361ac

^aP < 0.05, vs H pylori negative group,

^cP < 0.05, vs cagA^-H pylori infection group.

Table 3 Effect of H pylori infection on expression of Bcl-2

		Adenocarcinoma	Resection margin
H pylori (-)		0.411 ± 0132	0.371 ± 0.153
H pylori (+)	cagA (-)	0.696 ± 0.318a	0.487 ± 0.241a
	cagA (+)	0.849 ± 0.352a	0.619 ± 0.243ac

^aP < 0.05, vs H pylori negative group,

^cP < 0.05, vs cagA^-H pylori infection group.
