Glioblastoma multiforme (GBM) is one of the most malignant tumors of the central nervous system, and its treatment has always been a difficult clinical problem. Here, we evaluated HDAC1 expression patterns and their effect on prognosis based on GBM cases from TCGA and CGGA databases. Expression was compared between GBM samples and normal controls. High HDAC1 expression was found to be an indicator of poor prognosis in glioblastoma. We also established a protein-protein interaction network to explore HDAC1-related interacting proteins, including the epithelial-mesenchymal transition (EMT)-related protein VIM, which is closely associated with HDAC1. Consistently, functional enrichment analysis showed that several GBM tissues with high HDAC1 were enriched in the expression of cancer markers, such as those involved in glycolysis, hypoxia, inflammation, and some signaling pathways. Next, this study analyzed the effect of HDAC1 on invasive ability and the EMT signaling pathway in GBM cells in vitro. The results showed that an HDAC1 inhibitor (RGFP109) could inhibit the EMT process in glioma cells in vitro, thereby affecting the invasion and migration of cells. Similar results were obtained based on in vivo studies. Our data suggest that HDAC1 has the potential to be a powerful prognostic biomarker, which might provide a basis for developing therapeutic targets for GBM.

Concurrent inhibition of HDAC and BRD4, two well-established epigenetic targets for anti-tumor therapy, demonstrates the potential to enhance anti-tumor effects synergistically. The present study involves the development of a series of novel HDAC3/BRD4 dual inhibitors, followed by evaluation of their antitumor efficacy against several tumor models. Guided by scaffold hopping strategy, key pharmacophore of BRD4 inhibitor I-BET-151 was incorporated into an in-house developed HDAC3-selective inhibitor 17h.

Background: Atypical teratoid rhabdoid tumor (ATRT) is the most common malignant brain tumor in infants, and more than 60% of children with ATRT die from their tumor. ATRT is associated with mutational inactivation/deletion of , a member of the SWI/SNF chromatin remodeling complex, suggesting that epigenetic events play a critical role in tumor development and progression. Moreover, disruption of SWI/SNF allows unopposed activity of epigenetic repressors, which contribute to tumorigenicity.

Article Synopsis
  • Aging increases the risk of cardiovascular diseases, particularly cardiac diastolic dysfunction (CDD), which can lead to heart failure with preserved ejection fraction (HFpEF) in older adults.
  • Research indicates that green tea catechins, specifically epigallocatechin gallate (EGCG), may help improve cardiovascular issues related to aging in both animal models and humans, yet studies on its long-term effects on CDD are limited.
  • In this study, older mice treated with EGCG showed a prevention of aging-related CDD and improvements in heart function, attributed to enhanced expression of cardiac troponin I (cTnI) and reduced mitochondrial damage through the inhibition of histone deacetylase 1 (HDAC1).

Background: Hepatocellular carcinoma (HCC) continues to be a major cause of cancer-related death worldwide, primarily due to delays in diagnosis and resistance to existing treatments. Recent research has identified ATP-dependent chromatin remodeling-related genes (ACRRGs) as promising targets for therapeutic intervention across various types of cancer. This development offers potential new avenues for addressing the challenges in HCC management.
