Non-alcoholic fatty liver disease (NAFLD) encompasses hepatic steatosis, non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis, and hepatocellular carcinoma. It is the primary cause of chronic disorders, with a high prevalence but no approved treatment. Therefore, it indispensable to find trustworthy therapy for NAFLD. Recently, mounting evidence illustrates that Sirtuin 1 (SIRT1) strongly associated SIRT1 activation or overexpression attenuate NAFLD, while deficiency aggravates Besides, an array therapeutic agents, including natural compounds, synthetic traditional Chinese medicine formula, stem cell transplantation, alleviates NALFD via upregulation. Mechanically, NAFLD by reestablishing autophagy, enhancing mitochondrial function, suppressing oxidative stress, coordinating lipid metabolism, as well reducing hepatocyte apoptosis inflammation.

Liver disease is a significant global health issue, responsible for millions of deaths annually. Aging, characterized by the gradual decline in cellular and physiological functions, impairs tissue regeneration, increases susceptibility to liver diseases, leads health. Silent information regulator 1 (SIRT1), NAD⁺-dependent deacetylase, has emerged as pivotal factor modulating age-related changes liver. SIRT1 preserves function regulating essential aging-related pathways, including telomere maintenance, epigenetic modifications, senescence, intercellular communication, inflammation, mitochondrial function. Notably, levels naturally with age, contributing progression increased vulnerability injury. This review summarizes regulatory role aging its impact on diseases such fibrosis, alcoholic associated (ALD), metabolic dysfunction-associated steatotic (MASLD), steatohepatitis (MASH), hepatocellular carcinoma (HCC). We also discuss emerging therapeutic approaches, activators, gene therapy, nutritional interventions, which are evaluated their potential restore mitigate progression. Finally, we highlight future research directions optimize SIRT1-targeted therapies clinical applications conditions.

Succinylation represents an emerging class of post-translational modifications (PTMs), characterized by the enzymatic or non-enzymatic transfer a negatively charged four-carbon succinyl group to ϵ-amino lysine residues, mediated succinyl-coenzyme A. Recent studies have highlighted involvement succinylation in various diseases, particularly cancer progression. Sirtuin 5 (SIRT5), member sirtuin family, has been extensively studied for its robust desuccinylase activity, alongside deacetylase function. To date, only limited number SIRT5 substrates identified. These mediate diverse physiological processes such as glucose oxidation, fatty acid ammonia detoxification, reactive oxygen species scavenging, anti-apoptosis, and inflammatory responses. The regulation these activities can occur through either same activity acting on different distinct targeting substrate. Aberrant expression closely linked tumorigenesis disease progression; however, role remains controversial. exhibits dual functionalities: it promote tumor proliferation, metastasis, drug resistance, metabolic reprogramming, thereby oncogene; conversely, also inhibit cell growth induce apoptosis, functioning suppressor gene.

Abstract Liver disease poses a significant threat to global public health, with arsenic (As) recognized as major environmental toxin contributing liver injury. However, the specific mechanisms and protective effects of α‐lipoic acid (LA) remain unclear. Therefore, this study employs network toxicology pharmacology comprehensively analyze hepatotoxic mechanism As hepatoprotective LA, further verifies peroxisomal β‐oxidation lipophagy in process. The analysis results show that induces damage mainly through autophagy, apoptosis, lipid metabolism, oxidative stress, whereas LA exerts its properties by regulating metabolism. Further verifications find inhibits SIRT1 expression, activates P53 Notch pathways, damages mitochondria, β‐oxidation, increases accumulation, enhances liver, while intervention alleviates As‐induced accumulation targeting SIRT1, ameliorating mitochondrial damage, enhancing thereby alleviating damage. This clarifies hepatotoxicity provides theoretical basis for potential agent.

Brown adipose tissue (BAT) is the primary site for non-shivering thermogenesis in body and plays a crucial role maintaining core temperature. However, its function gradually declines with age. To mitigate age-related decline BAT thermogenic capacity, we treated progeroid mice metformin to investigate potential mechanisms by which can slow reduction function. We found that mice, after receiving treatment, showed significant improvement senescent state of brown adipocytes through activation SIRT1, effectively reduced mitochondrial oxidative stress. Additionally, slowed UCP1 expression levels tissue, thereby capacity mice. Moreover, inflammatory responses around cells, further improving overall tissue.
