To determine whether Gal-9 also induced cell death in B cell lymphoma, the diffuse large B-cell lymphoma (DLBCL) cell line OCI-Ly3 was treated with a recombinant form of Gal-9 (Gal-9 (0), called Gal-9 hereafter) (Nishi et al., 2005). This evidence concerns the gene LGALS9 and diffuse large B-cell lymphoma.
