Surface expression of NGAL-R was significantly higher in the majority of leukemic cell samples from the untreated CLL group (n = 47) than in normal PBMCs and B cells (2.4 and 8.4 times more, respectively; p = 0.016 and p = 0.0003, respectively; Figure 3C). The gene discussed is SLC22A17; the disease is B-cell chronic lymphocytic leukemia.
