CXCL13 and cancer: By elaboratively studying the CXCL13 transcriptional data from the TCGA, GTEx, CCLE and HPA databases, we created a portrait of the CXCL13 expression landscape in various cancers and investigated the correlations of CXCL13 expression with clinical features, prognosis, MMRs, MSI, TMB, TIME, immunotherapeutic response, CNV, DNMT, function annotation and related pathways.
