MS4A1 and diffuse large B-cell lymphoma: While the MYC protein expression level was not associated with CD20 expression in a selection of DLBCL cell lines (Figure S1D), the increased rituximab-mediated antibody-dependent cellular cytotoxicity (ADCC) was associated with increased CD20 surface expression (Figure 1D), pointing to a MYC-dependent regulation of CD20 expression, as previously suggested [21].
