Metabolism of chronic lymphocytic leukemia (CLL), a disease characterized by the relentless accumulation of mature B cells has been little explored. Bone marrow stromal cells provide a survival benefit to CLL cells, in part through PI3K/AKT pathway. Compared with proliferative B-cell lines, metabolic fluxes of oxygen and lactate were low in quiescent malignant B lymphocytes from CLL patients. Glycolysis (extracellular acidification rate, ECAR) was consistently low in CLL samples, but oxygen consumption (OCR) varied considerably. Higher OCR was associated with poor prognostic factors such as ZAP 70 positivity, unmutated IgVH, high β2M levels, and higher Rai stage. Co-culture with the …

A medical need exists for successfully treating people afflicted with leukemia, especially those who develop drug resistant forms. Relapse leukemia cases are particularly high within Hispanic populations where this disease is among the most frequently occurring cancer. Fourteen somatic mutations have been reported in Janus tyrosine kinase 3 (Jak3), including M511I and A573V, from patients with various forms of leukemia. To monitor drug sensitivity, a model system was developed. Indeed, many of these mutations have been shown to possess transforming ability in cell lines such as the IL-3 dependent pro-B cell line Ba/F3. As such, Ba/F3 cells were transformed to …
