While there was no variability in RelB between ABC cell lines (RIVA and U2932, Fig. 2C), as reported previously [19], GC-DLBCL cell line SUDHL10 was found to have significantly higher RelB (Fig. 2B, C) and a higher ratio of RelB to RelA (Fig. 2B). Here, RELB is linked to diffuse large B-cell lymphoma.
