This study aims to investigate the mechanism of Diels et Gilg flavonoids (THF) on acute hepatic injury (AHI). First, high-performance liquid chromatography (HPLC) fingerprints were established to obtain the main chemical components of THF. According to the network pharmacology databases, collect active targets of AHI and potential targets. Using interaction targets to construct a protein-protein interaction (PPI) network, followed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Finally, the affinity between the core targets and the main active ingredients was verified by molecular docking. Next, verified network pharmacology predictions with animal experiments. Mice were treated with THF (20, 40, and 80 mg/kg) for 7 days, and then built an acute liver injury model (lipopolysaccharide [LPS], 10 mg/kg). Detecting the liver biochemical indices, observe the liver pathological changes, and verify the key signaling pathway targets. HPLC showed that the main components of THF were quercetin and kaempferol. Seven active ingredients and 193 potential targets were screened, and 259 disease targets related to acute liver injury, quercetin, and kaempferol may be the main active ingredients in THF. PPI network analysis showed that tumor necrosis factor (TNF), interleukin-6 (IL-6), and tumor protein 53 (TP53) were potential targets of THF for the treatment of AHI. KEGG analysis showed that the phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway might be one of the main pathways in the treatment of AHI. The molecular docking results showed that active compounds both have strong binding activity with potential targets in PPI. In vivo experiments showed that THF could reduce the fibrosis and inflammation of liver tissue etc. Meanwhile, it could downregulate the alanine aminotransferase (ALT), aspartate aminotransferase (AST), IL-6, tumor necrosis factor alpha (TNF-α), C-reactive protein (CRP) levels, and the protein expressions of phosphorylated phosphoinositide 3-kinase (p-PI3K), phosphorylated protein kinase B (p-AKT), and the ratio of BCL2-associated X (BAX)/B-cell lymphoma-2 (BCL-2) in the liver tissue of the mice with acute liver injury and upregulate the level of interleukin-10 (IL-10). The treatment of acute liver injury with THF is characterized by multicomponents and multitargets, and its mechanism may be related to the alleviation of the inflammatory response, reduction of apoptosis, and regulation of the PI3K/AKT signaling pathway.

Objective: This study aimed to compare the expression of lymphoid enhancer factor 1 (LEF1) and β-catenin in basal cell adenoma (BA), desmoid-type fibromatosis (DF), and pancreatic solid pseudopapillary neoplasm (SPN) to evaluate their diagnostic utility in tumors associated with the WNT/β-catenin signaling pathway harboring the mutation of CTNNB1 gene 3 exon.
Methods: Eighty tumor patients, including 26 BAs, 30 DFs, and 24 SPNs, were analyzed. Immunohistochemical staining was identified positive (nuclear staining of LEF1 and β-catenin in > 50% of tumor cells).

Hypertrophic scar (HS) is a common fibroproliferative disorders with no fully effective treatments. The conversion of fibroblasts to myofibroblasts is known to play a critical role in HS formation, making it essential to identify molecules that promote myofibroblast dedifferentiation and to elucidate their underlying mechanisms. In this study, we used comparative transcriptomics and single-cell sequencing to identify key molecules and pathways that mediate fibrosis and myofibroblast transdifferentiation.

Introduction: Bone marrow-derived mesenchymal stem cell-derived extracellular vesicles (BMSC-EVs) are widely used for therapeutic purposes in preclinical studies. However, their utility in treating diabetes-associated atherosclerosis remains largely unexplored. Here, we aimed to characterize BMSC-EV-mediated regulation of autophagy and macrophage polarization.

Background: Due to sexual dimorphism in growth of penaeid shrimp, all-female cultivation is desirable for the aquaculture industry. 17β-estradiol (E2) has the potential to induce the male-to-female sex reversal of decapod species. However, the mechanisms behind it remain poorly understood.

A high-calorie diet and lack of exercise are the most important risk factors contributing to metabolic dysfunction-associated steatotic liver disease (MASLD) initiation and progression. The precise molecular mechanisms of mitochondrial function alteration during MASLD development remain to be fully elucidated. In this study, a total of 60 male C57BL/6J mice were maintained on a normal or amylin liver NASH (AMLN) diet for 6 or 10 weeks.
