Fig. 9From: Evaluation of the upregulation and surface expression of hypoxanthine guanine phosphoribosyltransferase in acute lymphoblastic leukemia and Burkitt’s B cell lymphomaHPRT internal cellular expression of HPRT in ALL patient samples. We evaluated the overall expression of HPRT in ALL patients to determine whether there was similar variability in expression. We found that while some patients exhibited a high expression of HPRT, some patients showed much lower levelsBack to article page
