The pro-apoptotic protein, Bax, has been reported to translocate from cytosol to mitochondria following exposure of cells to apoptotic stresses including cytokine withdrawal and treatment with glucocorticoids and cytotoxic drugs. These observations, coupled with reports showing that Bax causes the release of mitochondrial cytochrome c, implicate Bax as a(More)
The molecular basis for the clinical presentation of broad-range drug resistance in childhood ALL is poorly understood. In this study, high level cross-resistance to the glucocorticoid dexamethasone was encountered in a childhood ALL cell line selected for resistance to methotrexate (CEM MTX-R3). Compared with wild-type (WT) CEM cells, MTX-R3 cells had(More)
We have previously reported a strong correlation between poor prognosis in childhood neuroblastoma (NB) patients and high-level expression of the transmembrane efflux pump, Multidrug Resistance-associated Protein (MRP1), in NB tumour tissue. In this study, we inhibited the endogenous expression of MRP1 in 2 different NB tumour cell lines by stably(More)
