Genetic or pharmacological inactivation of CREBBP sensitizes B-cell Acute Lymphoblastic Leukemia to Ferroptotic Cell Death upon BCL2 Inhibition

A. Garcia-Gimenez, J. E. Ditcham, D. M. A. Azazi, E. Meduri, R. Asby, N. Sakakini, C. K. Lopez, N. Narayan, T. Beinortas, J. Bagri, S. Agrawal Singh, G. Giotopoulos, M. P. Murphy, S. J. Horton, B. Huntly, S. E. Richardson

This study identifies CREBBP mutations as a targetable vulnerability in B-ALL, showing that CREBBP inhibition sensitizes these cells to Venetoclax-induced ferroptosis.

Acute resistance to BET inhibitors remodels compensatory transcriptional programs via p300 co-activation

V. Shah, G. Giotopoulos, H. Osaki, M. Meyerhoefer, E. Meduri, B. Schubert, H. Yun, S. J. Horton, S. Agrawal-Singh, P. S. Haehnel, F. Basheer, D. Lugo, M. W. Kuehn, B. Guezguez, M. Theobald, , D. Sasca

This study identifies p300-mediated compensatory transcriptional programs that drive acute resistance to BET inhibitors in AML and suggests sequential BET- and p300-inhibition as a therapeutic strategy.

Mannose metabolism inhibition sensitizes acute myeloid leukemia cells to cytarabine and FLT3 inhibitor therapy by modulating fatty acid metabolism to drive ferroptotic cell death.

K. Woodley, L. S. Dillingh, G. Giotopoulos, P. Madrigal, K. M. Rattigan, C. Philippe, V. Dembitz, A. S. M. Magee, R. Asby, L. N. van de Lagemaat, C. Mappereley, S. C. James, J. H. Prehn, K. Tzelepis, K. Rouault-Pierre, , P. Gallipoli

This study shows that inhibiting mannose metabolism sensitizes AML cells to cytarabine and FLT3 inhibitors by promoting ferroptotic cell death through fatty acid metabolism changes.

Loss Of Kat2a Enhances Transcriptional Noise And Depletes Acute Myeloid Leukemia Stem-Like Cells

A. F. Domingues, R. Kulkarni, G. Giotopoulos, S. Gupta, S. Tan, E. Foerner, R. Romano Adao, K. Zeka, B. J. Huntly, S. Prabakaran, C. Pina
