Table 1 reports positivity to CD38, which is associated to both survival and proliferation in B-CLL cells. CD38 expression and signalling capacity are also linked to progression and response to therapy (Damle et al, 1999). However, in this study, no statistical correlation has been measured between enhanced CD38 expression and cell death induced by quercetin treatment (Supplementary Figure S1). This evidence concerns the gene CD38 and B-cell chronic lymphocytic leukemia.
