ObjectiveTo elucidate the metabolic characteristics of mitochondria in sepsis and review its cellular mechanism, so as to provide new ideas for the treatment of sepsis. MethodThe previous literatures and latest research results about mitochondrial metabolism during sepsis were reviewed. ResultsAt present, the researchers were not only concerned about the inflammatory response of sepsis, but also concerned about the systemic metabolic disorder caused by sepsis. It was believed that the damage of mitochondria caused by sepsis was one of the main reasons for the disorder of cell metabolism. During the sepsis, the patient’s metabolism had changed, for example, enhancement of aerobic glycolysis, lactic acid accumulation, elevated levels of fatty acids and triglycerides in blood, and so on. ConclusionMetabolic change during sepsis is related to mitochondria, which can provide some new methods for treatment of sepsis.
ObjectiveTo systematically review the role and potential clinical value of nicotinamide N-methyltransferase (NNMT) in gastric cancer, aiming to provide new insights for diagnosis, treatment, and prognosis of gastric cancer. MethodsRelevant literature from recent years on the involvement of NNMT in gastric cancer was thoroughly analyzed. The review focuses on the mechanisms by which NNMT influences cell proliferation, invasion, migration, and metabolic reprogramming in gastric cancer. Additionally, the study explores the potential of NNMT as a diagnostic and therapeutic target. ResultsNNMT was significantly overexpressed in gastric cancer tissues and was closely associated with tumor progression. It promoted malignant behaviors through various pathways, including metabolic regulation, enhancement of cancer cell proliferation and invasion, and alteration of the tumor microenvironment. Furthermore, NNMT played a crucial role in modulating host immune responses, which might impact the clinical prognosis of gastric cancer patients. ConclusionsNNMT exhibits significant biological functions in the development and progression of gastric cancer. As a potential biomarker and therapeutic target, it holds promising clinical value in the diagnosis and targeted treatment of gastric cancer, providing new strategies and evidence for precision therapy and prognosis assessment.
