Autophagy is an evolutionarily conserved cellular process through cell degradation of own protein aggregates or organelles to survive. Autophagy is closely related to many life activities, and especially, its dysfunctions might cause many diseases and physiological problems, such as tumorigenesis, neurodegeneration and microbial infection. In recent years, many studies found that epigenetic modifications may regulate the occurrence of autophagy and also play an important role in the process of autophgy biological function.However the exact mechanism of epigenetic modifications remains largely unknown. Here,we review the epigenetic effects on regulation of autophagy process, including histone acetylation activation and negatively feedback controlling autophagy, DNA methylation regulating cell autophagy process by changing autophagy related genes, and miRNA regulating autophagy related gene expression by targeted degradation and histone modifications. This review will help understand the relationship between epigenetic effects and autophagy.

Mechanisms of Autophagy in Ineffective Reperfusion After Ischemic Stroke.

Despite significant advancements in achieving high recanalization rates (80%-90%) for large vessel occlusions through mechanical thrombectomy, the issue of "futile recanalization" remains a major clinical challenge. Futile recanalization occurs when over half of patients fail to experience expected symptom improvement after vessel recanalization, often resulting in severe functional impairment or death. Traditionally, this phenomenon has been attributed to inadequate blood flow and reperfusion injury.

Objective: This study aims to investigate how the E3 ubiquitin ligase LITAF influences mitochondrial autophagy by modulating MCL-1 ubiquitination, and its role in the development of epilepsy.
Methods: Employing single-cell RNA sequencing (scRNA-seq) to analyze brain tissue from epilepsy patients, along with high-throughput transcriptomics, we identified changes in gene expression. This was complemented by in vivo and in vitro experiments, including protein-protein interaction (PPI) network analysis, western blotting, and behavioral assessments in mouse models.
Glaucoma is a leading cause of irreversible blindness, often associated with elevated intraocular pressure (IOP) due to trabecular meshwork (TM) dysfunction. Diabetes mellitus (DM) is recognized as a significant risk factor for glaucoma; however, the molecular mechanisms through which hyperglycemia affects TM function remain unclear. This study investigated the impact of high glucose on gene expression in human TM (HTM) cells to uncover pathways that contribute to TM dysfunction and glaucoma pathogenesis under diabetic conditions.

Currently, there is no cure or disease altering treatment for this disease. This is, in part, due to a lack of insight into early phenotypes of BPAN progression and 's role in establishing and maintaining neurological function.

( ) thwarts innate immune defense mechanisms in alveolar macrophages (AMs) during the initial stages of infection and in recruited bone marrow-derived cells during later stages of infection. However, how protective inflammatory responses are achieved during infection and the variation of the response in different macrophage subtypes remain obscure.
