Through RNA sequencing, we found that BAFF upregulates a myriad of genes that are known to promote chemoresistance in various cancers, including IL1, CXCL1/2, CXCL5, CXCL8, TRAF3, and PTGS2. Lastly, we found that BAFF protects these cells from cladribine-induced cell death in vitro. Here, CXCL8 is linked to cancer.
