Cdx2 small interference RNA upregulated phosphatase and tensin homolog, caspase-9 and caspase-3 mRNA expression. A: Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) analysis. The RNA samples (2 μg in each) extracted from MGC-803 cells, MGC-803/Cdx2 negative control cells and MGC-803/Cdx2 small interference RNA (siRNA) cells were subjected to RT-PCR for phosphatase and tensin homolog (PTEN), caspase-9, caspase-3 and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) mRNAs. RT-PCR for GAPDH was performed in parallel to show an equal amount of total RNA in the sample. Lane 1: MGC-803 group; Lane 2: MGC-803/Cdx2 negative control group; Lane 3: MGC-803/Cdx2 siRNA group; M: 600 bp marker; B: PTEN, caspase-9 and caspase-3 mRNA levels were measured at three groups, normalized to those of GAPDH and presented as mean ± SE. aP < 0.05 for MGC-803/Cdx2 siRNA group vs MGC-803 and MGC-803/Cdx2 negative control group.
