The molecular mechanisms underlying necroptosis in MetS primarily involve activation of the RIPK1-RIPK3-MLKL axis, particularly in metabolically active tissues such as skeletal muscle, liver, adipose tissue, and pancreatic β-cells. Although numerous experimental studies have linked necroptosis to metabolic inflammation and organ injury, a systematic synthesis of its mechanistic roles, biomarker relevance, and translational potential in MetS remains limited.

Male C57BL/6 mice were subjected to lipopolysaccharide (LPS)–induced AKI and treated intravenously with irisin (10 mg/kg).

In vitro, HK-2 cells were exposed to irisin, PGC-1α-specific siRNA, or the autophagy inhibitor chloroquine (CQ). Autophagic flux, lipid metabolism, mitochondrial function, and oxidative stress were subsequently evaluated. Irisin treatment markedly improved renal function in AKI mice by lowering serum creatinine and blood urea nitrogen levels, attenuating tubular injury, and suppressing inflammation and apoptosis. In HK-2 cells, irisin upregulated PGC-1α expression and enhanced autophagic activity, effects that were abolished by PGC-1α knockdown or CQ treatment. Additionally, irisin promoted lipid catabolism, reduced intracellular ROS accumulation, stabilized mitochondrial membrane potential, and protected cells from LPS-induced injury. Irisin alleviates AKI by activating PGC-1α–mediated autophagy, thereby mitigating inflammation, lipid accumulation, oxidative stress, and cellular damage.

Therefore, we tested the effects of different concentrations of RES and synthetic glucocorticoid dexamethasone (DEX) on the circadian clock, energy metabolism and mitochondrial function in fetal cardiomyocytes (CMCs) and cardiac fibroblasts (FBs). We found that RES affects the clock in both CMCs and FBs by increasing the stability of the clock protein PER2. In CMCs, the effect was mediated via the adenylyl cyclase signaling pathway.
