(Submitter supplied) Acute Lymphoblastic Leukemia (ALL) in infants (<1 year of age) is characterized by a high incidence of MLL translocations which is associated with a poor prognosis. Contributing to this poor prognosis is cellular drug resistance, especially to glucocorticoids like prednisolone. Although in vitro prednisolone resistance mechanisms have been proposed in pediatric ALL, it has never been studied in MLL-rearranged infant ALL, which are highly resistant to glucocorticoids in vitro and in vivo.

Analysis of primary MLL-rearranged ALL samples (>90% leukemic blasts) from untreated infants. In vitro prednisolone sensitivity was assessed by a 4day cytotoxicity (MTT) assay. Results provide insight into the molecular basis of glucocorticoid resistance in MLL-rearranged infant ALL patients.
