Patients with TP53-mutant acute myeloid leukemia (AML) respond poorly to currently available therapies, including the combination of venetoclax and hypomethylating agents, which presents a major therapeutic challenge. A new potential therapeutic target, the epichaperome complex, is a protein network consisting of heat-shock proteins and co-chaperones found in many tumors that support the survival of cancer cells. Researchers led by Bing Carter, Ph.D., and Michael Andreeff, M.D., Ph.D., identified high levels of epichaperomes in TP53-mutant AML cells. They found that targeting epichaperomes with...

Many patients with relapsed/refractory (R/R) large B cell lymphoma respond well to chimeric antigen receptor (CAR) T cell therapy targeting CD19. Still, most do not have a durable response, highlighting a need to understand the underlying resistance mechanisms. To address this issue, researchers led by Qing Deng, Ph.D., Michael Green, Ph.D., and Xubin Li, Ph.D., used single-cell RNA sequencing to establish a large dataset of CAR T cells to treat 59 patients with R/R large B cell lymphoma.   To show...
