GSTM1 and anemia (phenotype): Complete blood counts revealed significant leukopenia (mean 4800/μL, p = 0.0004; control 20,400/μL), anemia (mean Hb 7.7 g/dL, p < 0.0001; control 15.97 g/dL, mean Hct 22.53%, p < 0.0001; control 46.8%) and thrombocytopenia (mean 5.43 × 104/μL, p = 0.0004; control 81.3 × 104/μL) in primary YCU-AML1 mice compared to controls (Fig. 3B).
