In this prespecified analysis of the KarMMa trial, Paiva et al. show that persistent measurable residual disease (MRD) around the time of peak expansion correlates with primary resistance to idecabtagene vicleucel. Associations of outcomes with M-protein and circulating plasma cells over the 1-year course were distinct from their profiles following traditional myeloma treatments, highlighting the unique biological mechanism of CAR T therapy. The findings offer one of the first clinical guides to using biomarkers for tailoring salvage therapy following CAR T in myeloma. See article, p. 365. The hallmarks of cancer include deregulated cellular metabolism and epigenetic reprogramming. In this work, Toyoda et al. show that a viral oncogene encoded in human T-cell leukemia virus type 1 (HTLV-1), HTLV-1 bZIP factor (HBZ), upregulates TAp73 by its two molecular forms, HBZ RNA and HBZ protein, via...

A key metabolite, lactate, is typically secreted from cancer cells because its accumulation is toxic. Here, we report that a viral oncogene, HTLV-1 bZIP factor (HBZ), bimodally upregulates TAp73 to promote lactate excretion from adult T-cell leukemia-lymphoma (ATL) cells. HBZ protein binds to EZH2 and reduces its occupancy of the TAp73 promoter. Meanwhile, HBZ RNA activates TAp73 transcription via the BATF3-IRF4 machinery. TAp73 upregulates the lactate transporters MCT1 and MCT4. Inactivation of TAp73 leads to intracellular accumulation of lactate, inducing cell death in ATL cells. Furthermore, TAp73 knockout diminishes the development of inflammation in HBZ-transgenic mice. An MCT1/4 inhibitor, syrosingopine, decreases the growth of ATL cells in vitro and in vivo. MCT1/4 expression is positively correlated with TAp73 in many cancers, and MCT1/4 upregulation is associated with dismal prognosis.
