Ethnopharmacological relevance Acute lung injury (ALI), a critical complication of severe pneumonia, lacks targeted therapies. Astilbe chinensis (Maxim.) Franch. & Sav. possesses documented anti-inflammatory and respiratory-protective properties, yet its efficacy against ALI, bioactive constituents, and mechanisms remain unexplored. Aim of the study This study sought to evaluate the therapeutic efficacy and elucidate the mechanisms of action of Astilbe chinensis in the treatment of ALI through the application of network pharmacology and experimental methodologies. Materials and methods UHPLC-MS was used to analyze plasma components absorbed after Astilbe chinensis administration in rats. Inflammation-related targets and pathway enrichment analyses were conducted via network pharmacology technique. Pulmonary function was assessed using forced lung function measurements in a LPS-induced ALI mouse model. ELISA quantified inflammatory mediators, including pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, IFN-γ), chemokines (CCL5, CXCL2), and the anti-inflammatory cytokine IL-10 in mouse lung tissue. Flow cytometry evaluated macrophage polarization, and HE staining examined histopathological changes. qRT-PCR determined the mRNA expression levels of genes like CCR1, IKBKB, CXCL8, STAT3, CXCR4, AKT1, CCL3, CCL5, iNOS, Arg1, YM1 and CCR5, while simple western analysis evaluated the protein expression of t-AKT, p-AKT, t-STAT3, p-STAT3, CCR1 and CCR5 in mouse lung tissues affected by Astilbe chinensis . Results In this study, 20 blood-borne components of Astilbe chinensis were identified, predicted to interact with 369 potential molecular targets, with 331 related to ALI treatment. GO and KEGG pathway analyses showed that 36 targets participate in inflammatory processes, mainly via chemokine signaling pathways. Key targets identified include CCR1, IKBKB, CXCL8, STAT3, CXCR4, AKT1, and CCR5. The principal active constituents of Astilbe chinensis with potential efficacy against ALI were identified as cyclo(phenylalanyl-prolyl), 5-(6-hydroxy-6-methyloctyl)- -2,5-dihydrofuran-2-one, nicotinamide, 3-phenyllactic acid, and phloretin. In vivo studies demonstrated that Astilbe chinensis administration significantly increased M2 macrophage populations in lung tissue while improving forced pulmonary function parameters. Furthermore Astilbe chinensis reduces the levels of inflammatory factors TNF-α, IL-6, IFN-γ, CCL5 (the ligand for CCR5 and CCR1), and the neutrophil chemokine CXCL2 in the lung tissues of ALI mice, while significantly increasing the content of the anti-inflammatory cytokine IL-10. Additionally, Astilbe chinensis significantly downregulated gene expression of chemokine receptors CCR1, CCR5 and their ligands CCL3, CCL5 in ALI mouse lung tissues, while upregulating anti-inflammatory markers Arg1 and Ym1 (M2 macrophage biomarkers). Meanwhile, it exerts a notable inhibitory effect on the protein expression of CCR1, CCR5, p-AKT, and p-STAT3. Conclusion This study demonstrates that Astilbe chinensis significantly improves lung function and pulmonary inflammation in mice with ALI. Component identification combined with network pharmacology analysis reveals that its major anti-inflammatory components are cyclo(phenylalanyl-prolyl), 5-(6-hydroxy-6- -methyloctyl)-2,5-dihydrofuran-2-one, nicotinamide, 3-phenyllactic acid, and phloretin. The anti-inflammatory mechanism may involve inhibiting the gene and protein expression of inflammatory chemokines CCR1 and CCR5, suppressing the activity of the AKT/STAT3 signaling pathway, reducing the expression of inflammatory factors, promoting M2 macrophage polarization, and thereby increasing the release of anti-inflammatory genes and cytokines, ultimately exerting anti-inflammatory effects.

Objective Fujin Shengji (FJSJ) Powder has a positive effect on healing Diabetic Ulcers (DU), but the specific compounds at work have not been identified. Methods Network pharmacology was employed to investigate the primary constituents, potential therapeutic targets, and pharmacological mechanisms of FJSJ Powder treating DU. In vitro experiments were further performed to validate these findings: an LPS-induced RAW264.7 cell model was established to assess the anti-inflammatory effects of FJSJ Powder active constituents treating DU, while a high glucose-induced HUVEC model was cultured to verify the pro angiogenic effect of FJSJ Powder active constituents treating DU. Additionally, the mechanisms by which the optimal active monomers suppress inflammation and enhance angiogenesis in DU were investigated, focusing on the JAK2/STAT3 and PI3K/AKT signaling pathways. Results Network pharmacology identified quercetin (Que), kaempferol (Kae), abietic acid (Aba) and acetyl-11-keto-β-boswellic acid (AKBA) as the primary active constituents of FJSJ Powder treating DU; IL6, TNF, AKT1, and VEGFA were the core targets; and anti-inflammatory effect was mainly enriched in the JAK2/STAT3 signaling pathway, while angiogenesis promotion was mainly enriched in the PI3K/AKT signaling pathway. The vitro experiments have confirmed Que, Kae, Aba, and AKBA could play important roles in anti-inflammatory and angiogenic effects, with AKBA and Aba playing important roles in anti-inflammatory and pro-angiogenic effects, respectively. AKBA can upregulate P-JAK2, P-STAT3, IL-4, and downregulate INOS protein levels to exert anti-inflammatory. Aba can upregulate the P-AKT, P-PI3K, HIF-1α, and VEGFA proteins levels to promote angiogenesis. Conclusion FJSJ Powder promotes DU healing through dual-pathway regulation in anti-inflammatory and pro-angiogenic effects, with AKBA mediating the best anti-inflammatory activity through the JAK2/STAT3 pathway and Aba driving the strongest pro-angiogenic effects via the PI3K/AKT/HIF-1α/VEGFA axis, providing a basis for formula optimization.

Glia maturation factor-β (Gmfb), an actin filament debrancher, was initially identified in brain and recently linked to liver diseases. To investigate the role of hepatocyte Gmfb (hep-Gmfb) in liver reparative regeneration, hepatocyte-specific gmfb knockout (HepGKO) and overexpression (HepGOE) zebrafish strains were constructed. Both transgenic and wild-type (WT) zebrafish underwent partial hepatectomy (PHX) or were fed high fat, high cholesterol diets to model metabolism-associated steatotic liver disease (MASLD). Under physiological conditions, the HepGKO, HepGOE, and WT fish displayed similar survival, gross appearance, and liver histology. Following PHX, WT liver gmfb levels positively correlated with cell proliferation and proinflammatory cytokine levels. HepGOE showed enhanced regeneration and reduced liver steatosis compared to WT, while HepGKO exhibited opposite effects. In MASLD, WT liver gmfb increased with disease progression. HepGKO experienced worsening liver enlargement, steatosis, ballooning, inflammation, and endoplasmic reticulum stress, while HepGOE showed improvements. HepGOE liver had the highest cell proliferation, but all three groups showed similar levels of cell apoptosis. Moreover, elevated proinflammatory cytokines were observed across MASLD groups, being the highest in HepGKO and lowest in HepGOE. However, stat3 activation was the lowest in HepGKO and highest in HepGOE, while jnk and mapk/erk activation was consistent across the MASLD groups. In il6-treated primary hepatocytes, gmfb abundance influenced stat3 activation, and hep-gmfb abundance significantly affected actin filaments distribution in hepatocytes both in vivo and vitro. Conclusions: Hep-Gmfb boosts regenerative processes by enhancing hepatocyte proliferation, alleviating fatty liver histological abnormalities, and modulating the Il6/Stat3 signaling, potentially through remodeling of actin-filament network within hepatocytes.

Glycyrrhetinic acid (GA) is a saponin compound, isolated from licorice (Glycyrrhiza glabra), which has been wildly explored for its intriguing pharmacological and medicinal effects. GA is a triterpenoid glycoside displaying an array of pharmacological and biological activities, including anti-inflammatory, anti-bacterial, antiviral and antioxidative properties. In this study, we investigated the underlying mechanisms of GA on acne vulgaris through network pharmacology and proteomics. After the intersection of the 154 drug targets and 581 disease targets, 37 therapeutic targets for GA against acne were obtained. A protein–protein interaction (PPI) network analysis highlighted TNF, IL1B, IL6, ESR1, PPARG, NFKB1, STAT3 and TLR4 as key targets of GA against acne, which is further verified by molecular docking. The experimental results showed that GA inhibited lipid synthesis in vitro and in vivo, improved the histopathological damage of skin, prevented mast cell infiltration and decreased the level of pro-inflammatory cytokines, including TNF-α, IL-1β and IL-6. This study indicates that GA may regulate multiple pathways to improve acne symptoms, and the beneficial effects of GA against acne vulgaris might be through the regulation of sebogenesis and inflammatory responses.

Obesity stress and its associated metabolic disruption increase the likelihood and advancement of several forms of malignancies, such as postmenopausal lung cancer in humans. Also, the mechanism of lung cancer stress-related cognitive impairment and rhythm change are still unknown. Peimine (PE), an alkaloid derived from the Fritillaria genus , has the ability to mitigate the metabolic dysfunctions induced by obesity and inhibit tumor growth. The objective of this study was to investigate the regulatory impact of PE on obese mice with postmenopausal lung cancer generated by a high fat diet. Our initial findings indicate that PE can significantly reduce the metabolic dysfunction caused by a high-fat diet in mice. This is demonstrated by better glucose tolerance and insulin resistance, reduced accumulation of lipids in the liver, and improved histological alterations in the mammary fat pad. Subsequently, the treatment of PE suppressed the formation of lung tumors caused by a high-fat diet in mice models placed in their original location. In addition, PE effectively inhibited the formation of pre-existing lung tumors in a mouse model of postmenopausal women who were fed a high-fat diet. This treatment also reduced the severity of metabolic problems. Notably, laboratory studies demonstrated that insulin exposure increased the growth and movement of lung cancer cells, but this effect was significantly reduced when the cells were co-cultured with PE. Meanwhile, PE intervention can significantly alleviate cancer stress-related cognitive impairment and disturbed circadian rhythm changes and associated gene expression abnormalities in model animals. Analysis using bioinformatics and molecular biology techniques revealed that PE has the ability to decrease the expression levels of signal transducer and activator of transcription 3 (STAT3) in the liver, mammary fat pad, and tumor tissues of postmenopausal mice with obesity generated by a high-fat diet. The inhibitory effects of PE on the growth and movement of lung cancer cells induced by insulin were completely eliminated when STAT3 expression was removed. This suggests that the suppression of STAT3 expression is crucial for PE to exert its anti-cancer effects against lung cancer in the presence of high insulin levels. The findings of our study indicate that consuming PE is highly effective in preventing and treating lung cancer that is connected with obesity. This is achieved via regulating the signaling pathway of STAT3.

Tenghuang Jiangu Wan (THJGW) is a commonly utilized treatment for osteoarthritis (OA), yet its pharmacodynamic material basis and molecular mechanism remain inadequately understood. This study systematically characterized the in vitro and in vivo chemical components of THJGW using ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS). The pharmacodynamic material basis of THJGW in the treatment of OA was explored through a target network pharmacology approach and molecular docking technology. Cellular experiments were subsequently employed to validate the molecular mechanisms. Consequently, a total of 134 components from THJGW were identified in vitro , comprising 45 flavonoids, 10 iridoid glycosides, 39 phenylethanoid glycosides, 9 phenylpropanoids, 11 organic acids, 4 phenolics, and 16 other compounds. Additionally, 38 prototype absorbed components in serum were characterized for the purpose of network construction. 11 key components and 10 core targets (VEGFA, STAT3, RELA/NF-κB p65, PIK3R1, PIK3CA, MMP9, MMP1, IL-6, HDAC1, and FGF2) were determined by the target network pharmacology. Through Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, it was found that these intersection targets are associated with various signaling pathways such as pathways in cancer, lipid and atherosclerosis, and prostate cancer. Notably, the lipid and atherosclerosis pathway was closely linked to OA. The molecular docking results demonstrated strong binding affinities of the three core targets: IL-6, STAT3, and RELA/NF-κB p65. These results suggest that these targets may play a significant role for THJGW in treating OA. In vitro experiments showed that THJGW had notable protective effects on LPS-induced RAW264.7 macrophages by reducing levels of TNF-α and IL-6, and inhibiting phosphorylation expression of STAT3 and NF-κB p65 proteins related to the lipid and atherosclerosis pathway. This study provides insight into the pharmacodynamic material basis and mechanism of action for THJGW in the treatment of OA, which provide scientific evidence for the scientific application and improvement of quality standards for THJGW.

Background Prostate cancer (PCa) incidence and mortality rates are rising. Our previous research has shown that the combination of icariin (ICA) and curcumol (CUR) induced autophagy and ferroptosis in PCa cells, and altered lipid metabolism. We aimed to further explore the effects of the combination of ICA and CUR on gut microbiota, metabolism, and immunity in PCa. Methods A mouse subcutaneous RM-1 cell tumor model was established. 16 S rRNA sequencing was performed to detect changes in fecal gut microbiota. SCFAs in mouse feces, and the effect of ICA-CUR on T-cell immunity, IGFBP2, and DNMT1 were examined. Fecal microbiota transplantation (FMT) was conducted to explore the mechanism of ICA-CUR. Si-IGFBP2 and si/oe-DNMT1 were transfected into RM-1 and DU145 cells, and the cells were treated with ICA-CUR to investigate the mechanism of ICA-CUR on PCa development. Results After treatment with ICA-CUR, there was a decrease in tumor volume and weight, accompanied by changes in gut microbiota. ICA-CUR affected SCFAs and DNMT1/IGFBP2/EGFR/STAT3/PD-L1 pathway. ICA-CUR increased the positive rates of CD3 + CD8 + IFN-γ, CD3 + CD8 + Ki67 cells, and the levels of IFN-γ and IFN-α in the serum. After FMT (with donors from the ICA-CUR group), tumor volume and weight were decreased. SCFAs promote tumor development and the expression of IGFBP2. In vitro, DNMT1/IGFBP2 promotes cell migration and proliferation. ICA-CUR inhibits the expression of DNMT1/IGFBP2. Conclusions ICA-CUR mediates the interaction between gut microbiota and the DNMT1/IGFBP2 axis to inhibit the progression of PCa by regulating immune response and metabolism, suggesting a potential therapeutic strategy for PCa.

Ulcerative colitis (UC) is a common chronic, relapsing inflammatory bowel condition. Procyanidins (PC) are known for their antiangiogenic, anti-inflammatory, antioxidant, and antimetastatic properties. However, there is comparatively limited information on how PC interacts with UC. In this study, 5 mg/10 mL/kg body weight of PC was administered to mice with dextran sulfate sodium (DSS)-induced colitis mice. PC treatment prolonged the survival period of mice, ameliorated UC symptoms, reduced damage to the intestinal mucosal barrier, and increased the protein expression of ZO-1 and occludin in the DSS-treated mice. Importantly, PC treatment significantly reduced gene expression related to Th17 cell differentiation, including STAT3, SMAD3, TGF-β, and JAK1. The results of the flow cytometry analysis indicated significant increase in the number of Treg cells and a concomitant decrease in the proportion of Th17 cells in the colon following PC treatment. Additionally, PC increased the abundance of gut microbiota such as Bacteroidota, Oscillospiraceae, Muribaculaceae, and Desulfovibrionaceae, as well as the concentrations of acetate acid, propionate acid, and butyrate acid in the feces. PC also activated short-chain fatty acid receptors, such as G-protein coupled receptor 43 in the colon, which promoted the proliferation of Treg cells. The depletion of gut microbiota and subsequent transplantation of fecal microbiota demonstrated that PC’s effects on gut microbiota were effective in improving UC and restoring intestinal Th17/Treg homeostasis in a microbiota-dependent manner. This suggests that PC could be a promising functional food for the prevention and treatment of UC in the future.

The progression and severity of osteoarthritis (OA) are significantly associated with intra-articular synovitis, with the imbalance of M1/M2 macrophages serving as a critical driving factor in the pathogenesis of synovitis. In this study, we developed macrophage-targeted nanomicelles capable of scavenging reactive oxygen species (ROS) and releasing hydrogen sulfide (H 2 S). These nanomicelles were encapsulated within injectable methacrylate gelatin (GelMA) porous hydrogel microspheres, thereby creating a new H 2 S gas therapy platform for the treatment of osteoarthritis. In vitro experiments demonstrated that GelMA@FPLBD actively targeted macrophages, efficiently removed ROS, and gradually released H 2 S. This process inhibited the expression of phosphorylated extracellular signal-regulated kinase (p-ERK) and phosphorylated signal transducer and activator of transcription 3 (p-STAT3) in activated macrophages, thereby suppressing M1 polarization and promoting M2 polarization, resulting in significant anti-inflammatory effects. In vivo experiments utilizing a destabilization of the medial meniscus (DMM)-induced osteoarthritis (OA) rat model further revealed the anti-inflammatory and cartilage-protective properties of GelMA@FPLBD, effectively mitigating the progression of OA. Therefore, this study indicates that GelMA@FPLBD, functioning as a H 2 S gas therapy platform, holds significant promise for the treatment of osteoarthritis (OA).

Our previous study found that CpG oligodeoxynucleotides 1826 (CpG 1826), combined with mucin 1 (MUC1)-maltose-binding protein (MBP) (M-M), had certain antitumor activity. However, this combination is less than ideal for tumor suppression (tumors vary in size and vary widely among individuals), with a drawback being that CpG 1826 is unstable. To solve these problems, here, we evaluate MF59/CpG 1826 as a compound adjuvant with M-M vaccine on immune response, tumor suppression and survival. The results showed that MF59 could promote the CpG 1826/M-M vaccine-induced tumor growth inhibition and a Th1-prone cellular immune response, as well as reduce the individual differences of tumor growth and prolonged prophylactic and therapeutic mouse survival. Further research showed that MF59 promotes the maturation of DCs stimulated by CpG1826/M-M, resulting in Th1 polarization. The possible mechanism is speculated to be that MF59 could significantly prolong the retention time of CpG 1826, or the combination of CpG 1826 and M-M, as well as downregulate IL-6/STAT3 involved in MF59 combined CpG 1826-induced dendritic cell maturation. This study clarifies the utility of MF59/CpG 1826 as a vaccine compound adjuvant, laying the theoretical basis for the development of a novel M-M vaccine.Keywords:MF59;CpG 1826;compound adjuvant;tumor vaccine;MUC1-MBP;dendritic cells

This study investigated the immunomodulatory effects of soft-shelled turtle (Pelodiscus sinensis) peptide (TP) and Chinese pond turtle (Chinemys reevesii) peptide (TMP) on the intestinal mucosal immune system (IMIS). The results demonstrated that TP and TMP improved holistic immunity by restoring the vital immune organ atrophy and proliferation capacity of spleen immune cells. Moreover, TP and TMP significantly increased the serum content of IgA and cytokines that are responsible for immune cell activation and antigen clearance. TP and TMP promoted intestinal B cell activation, class switching recombination, and antibody secreting processes in a T cell-independent manner to increase the SIgA content. Furthermore, TP and TMP enhanced the intestinal barrier by increasing the protein expression of tight junctions (TJs) and adhesion junctions (AJs) and ameliorating the intestinal morphology. Mechanistically, TP and TMP activated the AHR/IL-22/STAT3/IL-6 axis to enhance the IgA response and improve the intestinal barrier, indicating their potential in intestinal health modulation.

Embryo implantation involves a sterile inflammatory reaction that is required for the invasion of the blastocyst into the decidua. Adenosine triphosphate (ATP) released from stressed or injured cells acts as an important signaling molecule to regulate many key physiological events, including sterile inflammation. We found that the amount of ATP in the uterine luminal fluid of mice increased during the peri-implantation period, and this depended on the presence of an embryo. We further showed that the release of ATP from receptive epithelial cells was likely stimulated by lactate released from the blastocyst through connexin hemichannels. The ATP receptor P2y2 was present on uterine epithelial cells during the preimplantation period and increased in the stromal cells during the time at which decidualization began. Pharmacological inhibition of P2y2 compromised decidualization and implantation. ATP-P2y2 signaling stimulated the phosphorylation of Stat3 in uterine luminal epithelial cells and the expression of early growth response 1 ( Egr1 ) and prostaglandin-endoperoxide synthase 2 ( Ptgs2, also known as Cox-2 ), all of which are required for decidualization and/or implantation, in stromal cells. Short exposure to high concentrations of ATP promoted decidualization of primary stromal cells, but longer exposures or lower ATP concentrations did not. The expression of genes encoding ATP-degrading ectonucleotidases increased in the decidua during the peri-implantation period, suggesting that they may limit the duration of the ATP signal. Together, our results indicate that the blastocyst-induced release of ATP from uterine epithelial cells during the peri-implantation period may be important for the initiation of stromal cell decidualization.
