Differences in the expressions of seven markers in ESCC, PCL, and HC groups (a) and in ESCC, PO, and HC groups (b)

(a) Markers showed significantly higher expressions in ESCC than in PCL and HC groups (p<0.05). The expressions of the 7.9, 15.9, and 25.1 kDa markers also showed significant differences (p<0.05) between PCL and HC groups; (b) Expressions of 8.0, 16.0, 16.2, and 25.1 kDa markers in the PO group were significantly lower than those in the ESCC group (p<0.01) (^* p<0.05 or ^* p<0.01 significant difference versus the groups before)
