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

(a) Expressions of the 2.7, 2.8, 3.0, and 5.6 kDa markers decreased significantly in the ESCC group compared with in the PCL and HC groups (p<0.05). The expressions of the 2.9 and 5.6 kDa markers decreased significantly in the PCL group compared with the HC group (p<0.05). ^* p<0.05 significant difference versus the groups before. (b) All these markers tended to increase expression after operation
