This study investigates the therapeutic effects of D-Xylose, a natural sugar, on non-alcoholic fatty liver disease (NAFLD), focusing on the expression of the lysozyme gene (LYZ) in macrophages. Using the single-cell dataset GSE136103 for NAFLD, researchers analyzed macrophage populations and other groups utilizing the Seurat package in R, while a differential analysis was performed on the NAFLD dataset GSE61260 using the limma package. Both in vitro and in vivo models, including cell culture, mouse models, RT-qPCR, Western blot, ELISA, and histopathological analyses, were employed to examine the effect of D-Xylose on lipid accumulation, LYZ expression, blood lipid levels, and inflammatory responses. The study found a significant upregulation of LYZ in free fatty acid (FFA)-treated cells and mouse liver tissues, with a subsequent reduction after D-Xylose intervention. Treatment with D-Xylose and Amlodipine led to a notable decrease in lipid accumulation, as evidenced by reduced triglyceride and cholesterol levels. D-Xylose demonstrated a greater improvement in lipid metabolism than Amlodipine. Additionally, D-Xylose significantly mitigated inflammatory responses, reducing levels of inflammatory markers such as IL1R, IL6, MYS8, TNF, NF-κB, and IL-1. Furthermore, D-Xylose administration significantly reduced liver weight and liver index, with a positive impact on serum liver function and blood lipid levels. The findings suggest that D-Xylose could be a therapeutic intervention for NAFLD by targeting LYZ expression in macrophages, thereby modulating lipid metabolism and inflammatory responses.
期刊介绍:
Cell Biochemistry and Biophysics (CBB) aims to publish papers on the nature of the biochemical and biophysical mechanisms underlying the structure, control and function of cellular systems
The reports should be within the framework of modern biochemistry and chemistry, biophysics and cell physiology, physics and engineering, molecular and structural biology. The relationship between molecular structure and function under investigation is emphasized.
Examples of subject areas that CBB publishes are:
· biochemical and biophysical aspects of cell structure and function;
· interactions of cells and their molecular/macromolecular constituents;
· innovative developments in genetic and biomolecular engineering;
· computer-based analysis of tissues, cells, cell networks, organelles, and molecular/macromolecular assemblies;
· photometric, spectroscopic, microscopic, mechanical, and electrical methodologies/techniques in analytical cytology, cytometry and innovative instrument design
For articles that focus on computational aspects, authors should be clear about which docking and molecular dynamics algorithms or software packages are being used as well as details on the system parameterization, simulations conditions etc. In addition, docking calculations (virtual screening, QSAR, etc.) should be validated either by experimental studies or one or more reliable theoretical cross-validation methods.
