miR-21 negatively correlated with PDCD4 expression in ESCC tissues. ((a), (b)) miR-21 was detected as a weak positive staining in normal epithelium, strongly positive staining of the tumor. ((c), (d)) PDCD4 was detected as a strongly positive staining in normal epithelium, weak positive staining of the tumor.
