Cdx2 mRNA and protein expression was suppressed in MGC-803/Cdx2 small interference RNA tumor tissue. A: Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) analysis. Total RNAs (2 μg in each) extracted from tumor tissue were subjected to RT-PCR for Cdx2 and β-actin mRNAs. RT-PCR for β-actin was performed in parallel to show an equal amount of total RNA in the sample; Lanes 1-3: MGC-803/Cdx2 small interference RNA (siRNA) group; Lanes 4-6: MGC-803/Cdx2 negative control group; Lanes 7-9: MGC-803 group; M: 600 bp marker; B: Western blotting analysis. Equal amounts of protein extracts (100 μg in each) were prepared from tumor tissue. The expression of Cdx2 protein was determined by Western blotting with an anti-Cdx2 antibody. The β-actin expression levels were determined as a control for equivalent protein loading. Lane 1: MGC-803 group; Lane 2: MGC-803/Cdx2 negative control group; Lane 3: MGC-803/Cdx2 siRNA group.
