Cll Metabolism Is Regulated By Prognostic Factors, Modulated By Stroma And Abrogated By Pi3k Inhibition, Hima Vangapandu
UT GSBS Dissertations and Theses (Open Access)
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 ...
