Cardiometabolic disease, emerging as a worldwide epidemic, is a combination of metabolic derangements leading to type 2 diabetes mellitus and cardiovascular disease. Genetic and environmental factors are linked through epigenetic mechanisms to the pathogenesis of cardiometabolic disease. Post-translational modifications of histone tails, including acetylation and deacetylation, epigenetically alter chromatin structure and dictate cell-specific gene expression patterns. The histone deacetylase family comprises 18 members that regulate gene expression by altering the acetylation status of nucleosomal histones and by functioning as nuclear transcriptional corepressors. Histone deacetylases regulate key aspects of metabolism, inflammation, and vascular function pertinent to cardiometabolic disease in a cell- and tissue-specific manner. Histone deacetylases also likely play a role in the metabolic memory of diabetes mellitus, an important clinical aspect of the disease. Understanding the molecular, cellular, and physiological functions of histone deacetylases in cardiometabolic disease is expected to provide insight into disease pathogenesis, risk factor control, and therapeutic development.

Background: Astrocytes, the most abundant glial cell type in the brain, will convert into the reactive state in response to proteotoxic stress such as tau accumulation, a characteristic feature of Alzheimer's disease (AD) and other tauopathies. The formation of reactive astrocytes is partially attributed to the disruption of autophagy lysosomal signaling, and inhibiting of some histone deacetylases (HDACs) has been demonstrated to reduce the molecular and functional characteristics of reactive astrocytes. However, the precise role of autophagy lysosomal signaling in astrocytes that regulates tau pathology remains unclear.

Acute myeloid leukemia (AML) with retinoic acid receptor gamma (RARG) fusions, which exhibits clinical features resembling acute promyelocytic leukemia (APL), has been identified as a new subtype with poor clinical outcomes. The underlying mechanism of RARG-fusion leukemia remains poorly understood, and needs to be explored urgently to instruct developing effective therapeutic strategies. Here, using the most prevalent RARG fusion, CPSF6-RARG (CR), as a representative, we reveal that the CR fusion, enhances the expansion of myeloid progenitors, impairs their maturation and synergizes with RAS mutations to drive more aggressive myeloid malignancies.

Vascular calcification significantly increases the incidence of cardiovascular disease and all-cause mortality patients with chronic kidney disease(CKD), severely affecting their health and lifespan. However, the mechanisms underlying vascular calcification in CKD remain incompletely understood, and the available therapeutic agents are limited. Research has found that the transformation of vascular smooth muscle cells(VSMCs) from a contractile phenotype to an osteoblast-like phenotype is a key step in CKD-related vascular calcification.

Targeted protein degradation (TPD) represents a promising alternative to conventional occupancy-driven protein inhibition. Despite the existence of more than 600 E3 ligases in the human proteome, so far only a few have been utilized for TPD of histone deacetylases (HDACs), which represent important epigenetic anticancer drug targets. In this study, we disclose the first-in-class Fem-1 homologue B (FEM1B)-recruiting HDAC degraders.
