By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.

Endocrine diseases often arise from disrupted hormone production, hormone signaling, or target-tissue responsiveness; for diabetes-focused endocrine disease models, insulin signaling regulates glucose uptake, hepatic glucose output, lipid metabolism, and β-cell compensation. Type 2 diabetes develops through interacting defects in insulin resistance, β-cell dysfunction, adipose inflammation, hepatic glucose overproduction, altered incretin signaling, and ectopic lipid metabolism. A major unresolved question is whether endocrine dysfunction is driven primarily by target-tissue insulin resistance, intrinsic β-cell failure, immune/inflammatory stress, or combined multi-organ failure that differs by disease stage.

Large-size fat particle sorting is widely used to isolate cells up to 200 μm in diameter. Single-cell flow sorting will allow greater insight into adipocyte heterogeneity by identifying gene expression, protein composition, and metabolic signatures at the single-cell level.

AMP-activated protein kinase, AMPK, is a conserved cellular energy sensor that responds to reduced cellular energy status and coordinates metabolism by increasing ATP-generating catabolic pathways while suppressing ATP-consuming anabolic processes. In metabolic disease research, the AMPK pathway is experimentally relevant because it regulates hepatic lipid synthesis, fatty acid oxidation, glucose production, skeletal-muscle glucose disposal, mTORC1-linked biosynthesis, autophagy, mitochondrial homeostasis, and whole-body energy balance. The central pathway logic is that energy stress, metformin, exercise-like stimulation, or direct AMPK activators increase AMPKα Thr172 phosphorylation and downstream substrate phosphorylation, including ACC and RAPTOR. Phosphorylation of ACC suppresses lipogenesis and supports fatty acid oxidation, whereas phosphorylation of RAPTOR suppresses mTORC1 signaling and links cellular energy status to growth and protein synthesis control. The pathway is linked

Liver histomorphometry is a quantitative histological approach used to measure structural alterations in hepatic tissue, including parenchymal loss, steatosis, fibrosis, and vascular remodeling, by combining stained tissue section analysis with stereological or computerized image-based measurements. Classical morphometric frameworks quantify volume fractions of liver compartments and fibrotic regions using systematic sampling and image analysis, enabling objective comparison of pathological changes across experimental groups. These approaches are widely applied in liver cirrhosis and fibrosis studies to reduce subjectivity in histological scoring and improve reproducibility of tissue evaluation. Recent methodological advances integrate automated image analysis and radiomics-based extraction of histological features from standard liver stains (e. g. , H&E and fibrotic stains), enabling quantitative correlation between morphometric features and fibrosis stages in non-alcoholic fatty live
