The differential expression of CTNN in ESCC.

(A) Semiquantitative reverse transcription-PCR (RT-PCR) was applied to compare expression status of CTTN, DMRT2, MCM10, SCYA26, HMGCS2 and SORBS2 between 8 pairs of primary ESCC tumor samples and matched normal esophageal epithelia. GAPDH was used as an internal control. (B) Representative of CTNN expression in a pair of ESCC (right) and adjacent normal tissue (left) detected by immunostaining with anti-CTNN antibody (brown). The slide was counterstained with hematoxylin (Original magnification: upper ×100, bottom ×200).
