Article Abstract
Histone acetylation is one of the most common epigenetic modifications, which plays an important role in tumorigenesis. However, the prognostic role of histone acetylation-regulators in ovarian cancer (OC) remains little known. We compared the expression levels of 40 histone acetylation-related genes between 379 OC samples and 88 normal ovarian tissues and identified 37 differently expressed genes (DEGs). We further explored the prognostic roles of these DEGs, and 8 genes were found to be correlated with overall survival ( < 0.1). In the training stage, an 8 gene-based signature was conducted by the least absolute shrinkage and selector operator (LASSO) Cox regression. Patients in the training cohort were divided into two risk subgroups according to the risk score calculated by the 8-gene signature, and a notable difference of OS was found between the two subgroups ( < 0.001). The 8-gene risk model was then verified to have a well predictive role on OS in the external validation cohort. Combined with the clinical characteristics, the risk score was proved to be an independent risk factor for OS. In conclusion, the histone acetylation-based gene signature has a well predictive effect on the prognosis of OC and can potentially be applied for clinical treatments.

Histone acetylation is an important epigenetic modification, modulating the development of many tumors. However, the functions of most histone acetylation-related genes (HARGs) and their prognostic values in Ewing sarcoma (EWS) remain unclear. The current study aimed to investigate the prognostic values and potential functions of HARGs in EWS.

Disulfiram (DSF), primarily applied in the therapy for alcohol addiction, has been demonstrated to possess the promising capability of anti-tumor in many human cancers, including esophageal squamous cell carcinoma (ESCC). To date, almost all studies about DSF in ESCC are focusing on investigating either drug combinations or nanoparticle-based delivery systems. However, the exact molecular mechanisms mediating the response to DSF in ESCC are totally unknown.

Mitochondria serve as central hubs for regulating numerous cellular processes that include metabolism, apoptosis, cell cycle progression, proliferation, differentiation, epigenetics, immune signaling, and aging. The voltage-dependent anion channel 1 (VDAC1) functions as a crucial mitochondrial gatekeeper, controlling the flow of ions, such as Ca, nucleotides, and metabolites across the outer mitochondrial membrane, and is also integral to mitochondria-mediated apoptosis. VDAC1 functions in regulating ATP production, Ca homeostasis, and apoptosis, which are essential for maintaining mitochondrial function and overall cellular health.

Background: Histone acetylation plays a critical role in the progression of acute myeloid leukemia (AML). This study aimed to explore the prognostic significance and biological implications of histone acetylation-related genes in AML and to identify potential oncoproteins and therapeutic compounds.
Methods: Genes associated with AML and histone acetylation were identified using the TCGA-LAML and IMEx Interactome databases.
Gastric cancer (GC) is considered a global health crisis due to the scarcity of early diagnostic methods. Numerous studies have substantiated the involvement of histone acetylation imbalance in the progression of diverse tumor types. The potential roles of long non-coding RNA (lncRNA) in improving prognostic, predictive as well as therapeutic approaches in cancers have made it a major hotspot in recent years.
