WebNov 10, 2024 · Amongst chemotherapy resistant patients [ 19 ], the majority of patients (61%) had BRD4 -amplified tumors. As we will discuss further, BRD4 appears to be directly related to chemoresistance via regulation of ALDH activity [ 67] and promotion of DNA damage repair [ 68 ]. WebFeb 1, 2024 · This result supported the use of BRD4 inhibitors for chemotherapy in AML patients. However, ongoing clinical trials using BRD4 blockades in AML patients indicated that the efficacy of BRD4 single-agent blockade is low and drug resistance may occur (Braun et al., 2024). Therefore, new therapeutic strategies for combining other targeted …
