Indigo naturalis (IN) is a medicinal and edible plant with obvious pharmacological effects such as anti-inflammation, improving blood circulation, and antibacterial. However, its therapeutic efficacy and mechanism of action against AS remain unclear. This study aims to integrate network pharmacology, molecular docking, and <i>in vitro</i> and <i>in vitro</i> experimental evaluations to uncover the active components and multitarget mechanisms of IN against AS. 10 active ingredients and 96 related target genes were identified, and gene functional enrichment analysis suggested that the toll-like receptor signaling pathway plays a core role in IN’s action against AS. Molecular docking revealed strong binding affinities between IN’s key ingredients and hub genes. <i>In vitro</i>, IN regulated the expression of inflammatory factors, migration factors, and TLR4, NF-<i>κ</i>B, and MyD88 proteins in cell inflammation models as predicted. <i>In vivo</i>, IN reduced aorta damage, cell apoptosis, blood lipids level, and inflammatory factors in LPS-induced AS mice, further downregulating the expression levels of TLR4, NF-<i>κ</i>B, and MyD88. This study confirmed the feasibility of IN for AS treatment from an anti-inflammatory perspective, highlighting the TLR4/MyD88/NF-<i>κ</i>B pathway as a critical mechanism.

Our findings illustrate that NCE effectively reduces lipid accumulation and triglyceride content, while simultaneously increasing free glycerol release. The reduction in lipid accumulation and induction of lipolysis were evidenced by the downregulation of lipogenesis proteins, such as fatty acid synthase and lipoprotein lipase, and the upregulation of hormone-sensitive lipase expression. Furthermore, the downregulation of adipogenic transcription factors, including peroxisome proliferator–activated receptor gamma, CCAAT/enhancer-binding protein <i>α</i>, and sterol regulatory element-binding protein 1, indicates the inhibition of adipocyte differentiation. Additionally, NCE treatment induced brown adipocyte phenotype by upregulating brown adipose tissue–specific proteins, such as uncoupling protein 1 and peroxisome proliferator–activated receptor-gamma coactivator 1<i>α</i>. Moreover, NCE led to the phosphorylation of AMPK, the master regulator of energy homeostasis. Pharmacological inhibition of AMPK using an AMPK inhibitor (Compound C) attenuated the lipogenesis inhibitory effect of NCE and reduced lipolysis and adipocyte browning. This suggests that AMPK activation is involved in these processes. GC–MS analysis reveals that NCE primarily consists of cholest-5-en-3-ol (27.15%) along with an array of fatty acids which possess favorable antiobesity properties.

Hepatic steatosis is a key pathological event in NAFLD. However, there is still lack of effective drugs for NAFLD treatment. Liquiritin (LIQ), derived from licorice root, exhibits antioxidative and anti-inflammatory properties, making it valuable in managing various conditions such as dermatological disorders, respiratory ailments, and gastritis. Here, we investigated the impact and underlying mechanisms of LIQ on hepatic steatosis in mouse primary hepatocytes (MPHs). Our study found that LIQ significantly decreased palmitic acid (PA)-induced lipid accumulation in MPHs. Additionally, LIQ remarkably increased the mRNA expression of Cpt1a, PPAR<i>α</i>, Ehhadh, Cyp4a10, and Acox1, suggesting that LIQ achieves its lipid-lowering effect by regulating mitochondria-mediated lipid β-oxidation. Furthermore, the regulatory effect of LIQ on the mitochondrial oxidative phosphorylation (OXPHOS) process was confirmed by Seahorse analysis. Mechanistically, bioinformatics analysis predicted VEGFA as a crucial target mediating the beneficial effects of LIQ against PA-induced lipid accumulation in MPHs. Notably, treatment with purified VEGFA protein partially counteracted the lipid-lowering properties of LIQ. Additionally, our data showed that LIQ promoted VEGFA degradation through the ubiquitin–proteasome pathway. Therefore, our findings not only confirm the lipid-lowering effects of LIQ in MPHs but also identify VEGFA as its potential target.

In this study, peach cultivated “Xiahui 5” was used as material to investigate the impact of UV-C on the softening, senescence, and postharvest quality of peaches. It was discovered that the application of UV-C postponed the peak of respiration, retarded the loss of firmness, and inhibited ethylene biosynthesis during peach fruit storage. The UV-C treatment led to the inhibition of the growth of soluble pectin content and the reduction of cellulose and hemicellulose content, together with the suppression of the activities of enzymes that break down cell walls. The application of UV-C treatment resulted in an increase in the total phenolic and flavonoid contents of peach fruit, accompanied by a corresponding enhancement in the activities of glutathione reductase (GR), catalase (CAT), ascorbate peroxidase (APX), and superoxide dismutase (SOD). This contributed to maintain the fruit’s normal redox balance and antioxidant capacity. The application of UV-C treatment resulted in a reduction in malondialdehyde (MDA) content and lipoxygenase (LOX) activity, thereby indicating that the oxidative damage of peach fruit during storage was inhibited by the UV-C. The application of UV-C maintained higher ATP content and induced the increase of cytochrome C oxidase (COX), succinate dehydrogenase (SDH), H⁺K⁺-ATPase, and Ca²⁺-ATPase activities involved in energy metabolism and had a significant impact in maintaining cell energy status.
