PARP9 and diffuse large B-cell lymphoma: Three macro PARPs, namely, PARP9, PARP14, and PARP15, were identified and named as B-aggressive lymphoma (BAL) proteins because of their overexpression in patients with high-risk diffused large B-cell lymphoma and their role as transcriptional regulators (Aguiar et al., 2000; Aguiar et al., 2005).
