Mitochondrial dysfunction in the pathogenesis of acute pancreatitis

引用

Hepatobiliary & Pancreatic Diseases International 2025年第1期24卷 76-83页

作者： Xia Chen Rui Zhong Bing Hu Department of Gastroenterology and Hepatology West China HospitalSichuan UniversityChengdu 610041China Department of Gastroenterology Clinical Medical College and The First Affiliated Hospital of Chengdu Medical CollegeChengdu 610500China

The mechanism of cell damage during acute pancreatitis (AP) has not been fully elucidated, and there is still a lack of specific or effective treatments. Increasing evidence has implicated mitochondrial dysfunction as a key event in the pathophysiology of AP. Mitochondrial dysfunction is closely related to calcium (Ca^(2+)) overload, intracellular adenosine triphosphate depletion, mitochondrial permeability transition pore openings, loss of mitochondrial membrane potential, mitophagy damage and inflammatory responses. Mitochondrial dysfunction is an early triggering event in the initiation and development of AP,and this organelle damage may precede the release of inflammatory cytokines, intracellular trypsin activation and vacuole formation of pancreatic acinar cells. This review provides further insight into the role of mitochondria in both physiological and pathophysiological aspects of AP, aiming to improve our understanding of the underlying mechanism which may lead to the development of therapeutic and preventive strategies for AP.

The tumor microenvironment(TME)plays a critical role in the development and treatment of liver cancer,which ranks sixth in incidence and third in mortality worldwide,according to the“Global Cancer Statistics 2022”.Hepatocellular carcinoma(HCC),the most common form of liver cancer,is heavily influenced by the TME,which affects tumor growth,invasion,metastasis,and the response to various *** advancements in surgery,liver transplantation,targeted therapies,and immunotherapy,the complexity of the TME often limits treatment efficacy,especially in advanced-stage HCC *** TME consists of a dynamic interaction between tumor cells,immune cells,fibroblasts,blood vessels,and signaling molecules,all of which contribute to cancer progression and therapy *** the HCC TME is essential for designing effective,personalized treatments and improving patient *** research highlights the value of imaging technologies as non-invasive tools to evaluate the TME,offering new possibilities for more targeted therapies and better prognosis monitoring in HCC patients.
