TNFSF13 and central nervous system cancer: In correlation analysis, the only significant correlation spotted was that between APRIL and BAFF (Spearman's rho = 0.402, p<0.012) and BCMA and TACI (Spearman's rho = 0.303, p<0.015) (Table S3), indicating that, in gliomas, a combined transcription of ligands (BAFF, APRIL) or receptors (BCMA, TACI) occurs.
