Expression of a proliferation-inducing ligand (APRIL), B cell-activating factor (BAFF), BAFF receptor (BAFFR), TNFR homolog transmembrane activator and Ca²⁺ modulator (CAML) interactor (TACI), and B cell maturation antigen (BCMA) in the Cancer Cell Line Encyclopedia (141), reporting the RNAseq data of 1,156 human cancer cell lines (A) using the cBioPortal web resource (139, 140). A pink bar denotes the presence of the corresponding ligand mRNA, while a gray one denotes the absence of mRNA for the corresponding ligand/receptor. Note that a co-occurrence of ligands and receptors is not always evidenced, as also shown in the Table presented in (B).
