Cdx2 small interference RNA significantly increased phosphatase and tensin homolog, cleaved caspase-9 and cleaved caspase-3 protein concentrations while pro-caspase-9 and pro-caspase-3 are decreased. A: Western blotting analysis. Whole protein extracts (100 μg in each) were prepared from MGC-803 cells, MGC-803/Cdx2 negative control cells and MGC-803/Cdx2 small interference RNA (siRNA) cells. The expression of phosphatase and tensin homolog (PTEN), pro-caspase-9, p37 cleaved caspase-9, pro-caspase-3, and p17 cleaved caspase-3 was determined by Western blotting with an anti-PTEN, pro-caspase-9, cleaved caspase-9, pro-caspase-3 and cleaved caspase-3 antibody. The glyceraldehyde-3-phosphate dehydrogenase (GAPDH) protein 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; B: PTEN, pro-caspase-9, p37 cleaved caspase-9, pro-caspase-3 and p17 cleaved caspase-3 protein 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.
