Note:A. Protein expression of PRPS1 mutants in REH cells by Western blotting. His-PRPS1 represents the PRPS1 fusion protein with His label, that is, the exogenous PRPS1 protein. B. Detection of the drug sensitivities of PRPS1 I72 mutations to 6-MP in REH cells by drug sensitivity experiment. P=0.000, P=0.998, compared with REH cells transfected with pGV303 PRPS1 WT plasmid. C. Detection of the drug sensitivities of PRPS1 I72 mutations to 6-TG in REH cells by drug sensitivity experiment. P=0.000, P=0.903, compared with REH cells transfected with pGV303 PRPS1 WT plasmid.
