Figure 6From: SHP1-mediated cell cycle redistribution inhibits radiosensitivity of non-small cell lung cancerEffects of stable SHP1 siRNA on the expression of cell cycle-related proteins. Protein levels of SHP1, p16, CDK4 and Cyclin D1 were examined in A549S1/siSHP1 and A549S1/siMock by western blot. GAPDH was used as an internal control (*P < 0.05, **P < 0.01 vs. the A549S1/siMOCK group).Back to article page
