In addition, TDAG8 gene expression is reduced in several lymphomas such as diffuse large B-cell lymphoma (DLBCL) (1.4- and 1.9-fold) [33, 34], follicular lymphoma (FL) (1.4- and 2.0-fold) [33, 34], pleural effusion lymphoma (PEL) (2.7-fold) [33], and Burkitt lymphoma (BL) (1.8-fold) [33] (Table 1). Here, GPR65 is linked to follicular lymphoma.
