The correlation between S100A14 overexpression and MMP2 overexpression in paired breast cancer tissues with different p53 status

These results were analyzed by the Pearson χ² test. p values with significance are shown as superscripts.

Characteristics	S100A14 expression		Case no.
	Non-overexpressed*	Overexpressed*
Overall			49
MMP2 expression in cases with wild type p53
Non-overexpressed,a, n (%)	3 (75.0)	1 (25.0)	4
Overexpressed,an (%)	6 (23.1)	20 (66.9)0.035	26
MMP2 expression in cases with mutant p53
Non-overexpressed,an (%)	2 (33.3)	4 (66.6)	6
Overexpressed,an (%)	1 (76.9)	12 (23.1)0.154	13

^a For S100A14 and MMP2 mRNA expression levels, the matched cancer/normal ratio >1 was taken as overexpressed group, and the ratio ≤1 was taken as the non-overexpressed group.
