• BRD4–RAC1 Co-Targeting in Breast Cancer

  2026-08-09

  The reference study shows that simultaneous inhibition of BRD4 and RAC1 suppresses growth, stemness, migration, and tumorigenesis across luminal-A, HER2-positive, and triple-negative breast cancer models. Its mechanistic contribution is the identification of a c-MYC–G9a–FTH1 pathway and HDAC1-associated chromatin response that connect dual pathway inhibition to autophagy, senescence, and reduced tumor growth.

• SLC2A5 Fructose Metabolism in Primary CNS Lymphoma
