Proteasome subunit catalytic activity in relapsed childhood ALL and AML patients. a Correlation of β5i/β5 protein expression and β5i/β5 catalytic activity ratios. b β5i/β5 catalytic activity ratios in pre-B ALL patients (n = 18) compared to T-ALL patients (n = 4) and AML patients (n = 10), and c β5i/β5 catalytic activity ratios in patients who achieved complete remission (n = 14) versus those who did not (n = 18). Closed circles represent pre-B ALL patients, open triangles T-ALL patients and open squares AML patients. The line denotes the mean
