Bromodomains are protein domains that serve as "readers" of acetylated lysine marks and mediate DNA-templated processes. In this issue of Cell Chemical Biology, Olzscha et al. (2017) report that the CBP/p300 bromodomains mediate the formation of amyloid-like aggregates and that inhibitors specific to these bromodomains reduce the degree of protein aggregation and mitigate HDAC inhibitor-induced cytotoxicity.

H3K27 acetylation (H3K27ac) is crucial in muscle development as it regulates gene expression. Dysregulation of H3K27ac level has been linked to muscle-related diseases such as Duchenne muscular dystrophy, yet the mechanisms through which H3K27ac influences myogenic differentiation are not fully understood. Here, we utilized the SGC-CBP30 drug, a CBP/p300 bromodomain inhibitor, to reduce H3K27ac level and investigated its effect on myogenic differentiation of porcine skeletal muscle satellite cells.

CBP and p300 are versatile transcriptional co-activators that play essential roles in regulating a wide range of signaling pathways, including Wnt/β-catenin, p53, and HIF-1α. These co-activators influence various cellular processes such as proliferation, differentiation, apoptosis, and response to hypoxia, making them pivotal in normal physiology and disease progression. The Wnt/β-catenin signaling pathway, in particular, is crucial for cellular proliferation, differentiation, tissue homeostasis, and embryogenesis.

Tumor-associated neutrophils (TANs) have been shown to promote immunosuppression and tumor progression, and a high TAN frequency predicts poor prognosis in triple-negative breast cancer (TNBC). Dysregulation of CREB-binding protein (CBP)/P300 function has been observed with multiple cancer types. The bromodomain (BRD) of CBP/P300 has been shown to regulate its activity.

Castration resistant prostate cancer (CRPC) remains an incurable disease stage with ineffective treatments options. Here, the androgen receptor (AR) coactivators CBP/p300, which are histone acetyltransferases, were identified as critical mediators of DNA damage repair (DDR) to potentially enhance therapeutic targeting of CRPC. Key findings demonstrate that CBP/p300 expression increases with disease progression and selects for poor prognosis in metastatic disease.
