For mechanistic and functional studies, we utilized human B cell lymphoma cell lines that harbor the FL-hallmark t(14;18)(q32:q21)IGH::BCL2 translocation, including two ARID1AWT cell lines (OCI-Ly1 and OCI-Ly8) and an ARID1AMUT cell line (Karpas422). Here, BCL2 is linked to B-cell non-Hodgkin lymphoma.
