Background Asthma is a chronic inflammatory airway disease that remains inadequately controlled by existing conventional treatments. A traditional Chinese medicine (TCM) formula of Yangke powder (yǎng ké sǎn-YKS) has demonstrated potential in alleviating asthma symptoms and reducing its acute exacerbation. Despite clinical evidence supporting its benefit, there is still insufficient understanding of the active compounds in YKS and their underlying mechanisms, which limits its broader clinical application. Objective This study aims to identify the key active ingredients in YKS and explore their mechanisms, particularly through the PI3K/AKT/NF-κB pathways, to provide a scientific basis for its application in asthma treatment. Methods We employed UPLC-Q-Exactive Orbitrap-MS to analyze YKS constituents, identified key ingredients, and explored asthma treatment mechanisms through bioinformatics, network pharmacology, Mendelian randomization, and molecular docking. The asthma model was evaluated using ovalbumin (OVA) and pulmonary function tests, while pathological examination was conducted using hematoxylin and eosin (HE), periodic acid-Schiff (PAS), and Masson trichrome stains. Concentrations of IgE, IL-4, and IL-5 were measured by ELISA, and protein and mRNA expressions were confirmed via qPCR, immunohistochemistry, and Western blot analysis. Results A total of 174 compounds were identified in YKS by UPLC-MS, with 49 detected in the bloodstream, indicating their role as active ingredients. Bioinformatics analysis revealed 353 asthma-related targets and 972 potential targets for YKS. Key targets such as AKT1, TNF, and IL1B were validated by molecular docking. Our studies indicated that YKS modulates asthma primarily through the PI3K/Akt and NF-κB pathways, improving airway resistance, reducing inflammation, mucus production, and airway remodeling, and decreasing Th2 cytokines and IgE levels. Conclusion This investigation identifies Kaempferol, Norephedrine, Cynaroside, Genistein, and Rutin as critical active ingredients in YKS, impacting key biomarkers such as AKT1, TNF, and IL1B. These substances effectively modulate the PI3K/AKT/NF-κB pathway, enhancing the management of allergic asthma.

Hyperuricemia is chronic metabolic disease with a high incidence, and it has become the “fourth highest” health risk in modern times. Isorhamnetin is a natural flavonoid found in a variety of plants, especially fruits such as buckthorn. In vivo hyperuricemia ameliorating effect of isorhamnetin and the specific molecular mechanism were profoundly investigated through a hyperuricemia mice model in the present study. The results demonstrated that isorhamnetin showed a significant uric acid-lowering effect in mice. Isorhamnetin was able to reduce uric acid production by inhibiting XOD activity. On the other hand, it reduced the expression of GLUT9 to inhibit uric acid reabsorption and enhanced the expression of ABCG2, OAT1, and OAT3 to promote uric acid excretion. Metabolomics analysis revealed that isorhamnetin gavage restored the purine metabolism and riboflavin metabolism disorders, and thus significantly alleviated the hyperuricemia in mice. Further, the alleviating effect of isorhamnetin on hyperuricemia-induced renal inflammation and its specific mechanism were explored through network pharmacology and molecular validation experiments. Network pharmacology predicted that seven targets were enriched in the PI3K/AKT pathway (CDK6, SYK, KDR, RELA, PIK3CG, IGF1R, MCL1) and four targets were enriched in the NF-κB pathway (SYK, PARP1, PTGS2, RELA). Western blot validated that isorhamnetin inhibited the phosphorylation of PI3K and AKT and down-regulated the expression of NF-κB p65. It indicated that isorhamnetin could inhibit the PI3K/AKT/NF-κB signaling pathway to reduce the levels of renal inflammatory factors (TNF-α, IL-β and IL-6) and ultimately ameliorate the hyperuricemia-induced renal inflammation in mice. This study will provide comprehensive and penetrating theoretical basis for the application of isorhamnetin in the field of functional foods or dietary supplements to improve hyperuricemia.

Background Ang II induces hypertensive heart failure (HF) via hemodynamic and non-hemodynamic actions. Lycorine (LYC) is an alkaloid derived from Lycoris bulbs, and it possesses anti-cardiovascular disease-related activities. Herein, we explored the potential LYC-mediated regulation of Ang II-induced HF. Methods Over 4 weeks, we established a hypertensive HF mouse model by infusing Ang II into C57BL/6 mice using a micro-osmotic pump. For the final two weeks, mice were administered LYC via intraperitoneal injection. The LYC signaling network was then deduced using RNA sequencing. Results LYC administration strongly suppressed hypertrophy, myocardial fibrosis, and cardiac inflammation. As a result, it minimized heart dysfunction while causing no changes in blood pressure. The Nuclear Factor kappa B (NF-κB) network/phosphoinositol-3-kinase (PI3K)-protein kinase B (AKT) was found to be a major modulator of LYC-based cardioprotection using RNA sequencing study. We further confirmed that in cultured cardiomyocytes and mouse hearts, LYC reduced the inflammatory response and downregulated the Ang II-induced PI3K-AKT/NF-κB network. Moreover, PI3K-AKT or NF-κB axis depletion in cardiomyocytes completely abrogated the anti-inflammatory activities of LYC. Conclusion Herein, we demonstrated that LYC safeguarded hearts in Ang II -stimulated mice by suppressing the PI3K-AKT/NF-κB-induced inflammatory responses. Given the evidence mentioned above, LYC is a robust therapeutic agent for hypertensive HF.

Introduction Kidney tubular epithelial injury is one of the key factors in the progression of diabetic nephropathy (DN). Wogonin is a kind of flavonoid, which has many pharmacological effects, such as anti-inflammation, anti-oxidation and anti-fibrosis. However, the effect of wogonin in renal tubular epithelial cells during DN is still unknown.Materials and Methods STZ-induced diabetic mice were given doses of wogonin (10, 20, and 40 mg/kg) by intragastric administration for 16 weeks. The metabolic indexes from blood and urine and pathological damage of renal tubules in mice were evaluated. Human tubular epithelial cells (HK-2) were cultured in high glucose (HG) condition containing wogonin (2μM, 4μM, 8μM) for 24 h. Tubular epithelial cell inflammation and autophagic dysfunction both in vivo and in vitro were assessed by Western blot, qRT-PCR, IHC, and IF analyses.Results The treatment of wogonin attenuated urinary albumin and histopathological damage in tubulointerstitium of diabetic mice. We also found that wogonin down-regulated the expression of pro-inflammatory cytokines and autophagic dysfunction in vivo and in vitro. Molecular docking and Cellular Thermal Shift Assay (CETSA) results revealed that mechanistically phosphoinositide 3-kinase (PI3K) was the target of wogonin. We then found that inhibiting PI3K eliminated the protective effect of wogonin. Wogonin regulated autophagy and inflammation via targeting PI3K, the important connection point of PI3K/Akt/NF-κB signaling pathway.Conclusion Our study is the first to demonstrate the novel role of wogonin in mitigating tubulointerstitial fibrosis and renal tubular cell injury via regulating PI3K/Akt/NF-κB signaling pathway-mediated autophagy and inflammation. Wogonin might be a latent remedial drug against tubular epithelial injury in DN by targeting PI3K.

Aim Inflammation and apoptosis are main pathological processes that lead to the development of hyperuricemic nephropathy (HN). This study aims to explore whether baicalin (BA) and baicalein (BAI) can relieve the damage through PI3K/AKT/NF-κB signal pathway and provide more reliable and precise evidence for the treatment of HN. Methods HN mice were induced by yeast extract with potassium oxonate (PO), and HK-2 cells were induced by monosodium urate (MSU). Molecular docking, western blot, q-PCR, and other methods were used to explore the changes of various indicators in HN mice and HK-2 cells. Results Molecular docking results showed that BA and BAI had good binding ability with PI3K, AKT, p65 and IκBα. BA and BAI significantly ameliorated the levels of renal function, decreased the p-PI3K, p-AKT and p-p65 expression, down-regulated the BAX/BCL2 and CASP3, and blunted the mRNA levels of tumour necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-18 in both renal tissue of HN mice and HK-2 cells induced by MSU. BA and BAI also decreased the oxidative stress level of MSU-induced HK-2 cells. Conclusion BA and BAI were confirmed to attenuate HN through alleviating renal inflammatory and apoptosis in cells and tissues by inhibiting PI3K/AKT/NF-κB pathway. BA and BAI were expected to be developed as new anti-HN drugs.

This study aims to elucidate the target and mechanism of baicalin, a clinically utilized drug, in the treatment of neuroinflammatory diseases. Neuroinflammation, characterized by the activation of glial cells and the release of various pro-inflammatory cytokines, plays a critical role in the pathogenesis of various diseases, including spinal cord injury (SCI). The remission of such diseases is significantly dependent on the improvement of inflammatory microenvironment. Toll-like receptor 4/myeloid differentiation protein 2 (TLR4/MD2) complex plays an important role in pathogen recognition and innate immune activation. baicalin, a natural flavonoid, is renowned for its potent anti-inflammatory property. In this study, we discovered that baicalin significantly reduced the activation of glial cells and the levels of pro-inflammatory cytokines at the lesion site of SCI mice, thereby mitigating demyelination and neuronal damage. By directly occupying the active pocket of TLR4/MD2 complex on microglia, baicalin inhibited PI3K/AKT/NF-κB pathway, thereby exerting its anti-inflammatory effect. These findings were corroborated in mice induced by lipopolysaccharide, a TLR4 agonist. Furthermore, baicalin indirectly altered phenotype of astrocytes by reducing secretion of TNF-α, IL-1α, and C1q levels from microglia. Our work demonstrated that baicalin effectively alleviated neuroinflammation by directly targeting microglia and indirectly modulating astrocytes phenotype. As a natural flavonoid, baicalin holds significant potential as a therapeutic candidate for diseases characterized by neuroinflammation.

Camellia oleifera Abel ( C. oleifera ) is a multifunctional oilseed, which is rich in many biological active substances with health-promoting properties, especially polyphenols. Previous research revealed that camellia oil phenolics exhibited anti-inflammatory effect, which originated from seed. Thus, we aimed to explore the components of camellia seed phenolics and its potential mechanism of anti-inflammation. Initially, fractional extraction was processed to prepare the phenolics from camellia seed kernels, and we compare four different fractions of phenolics under the LPS-induced Caco-2/RAW264.7 coculturing model. Results showed that free phenolics (FP) had best effect on alleviating pro-inflammatory cytokines (IL-1β, IL-6, IL-8 and TNF-α) compared to esterified-bound phenolics (EP), glycosylated-bound phenolics (GP) and insoluble-bound phenolics (IP). Furthermore, FP reduced inflammation by suppressing the PI3K/Akt/NF-κB signaling pathway and effectively inhibited LPS-induced intestinal permeability increase, tight junction related proteins loss (ZO-1, claudin-1). Same results obtained, as the transepithelial electrical resistance (TEER) and alkaline phosphatase (AKP) activity of high-dose FP treated group was high than model group. Finally, molecular docking was used for evaluating the anti-inflammatory effect for phenolic monomer. KGRG (kaempferol −3-O-(2-O-glucopyranosyl-6-O-rhamnopyranosyl)-glucopyranoside), KXR (kaempferol 3-O-(2′’-xylopyranosyl)-rutinoside) and leucoside (kaempferol 3-O-sambubioside) show lower binding energy docking with NF-κB, PI3K and Akt protein, indicating better interactions, which might be effective constituents against inflammation. Subsequently, five major polyphenols were obtained to validate the docking results, especially, indicating the best anti-inflammatory activities of KGRG. Overall, this research sheds insights on the therapy of phenolics from C. oleifera seed towards LPS-induced intestinal inflammation model in vitro and its related mechanism.

Paeonol (2'-hydroxy-4'-methoxyacetophenone) is an active component isolated from the root of Paeonia Suffruticosa Andrews. We previously found that paeonol inhibited vascular cell adhesion molecule-1 (VCAM‑1) expression, and thus may be useful for the prevention and treatment of rabbit atherosclerosis (AS); however, the underlying mechanisms are not yet well known. Recently, microRNAs (miRNAs or miRs) have been reported to play an important role in the pathogenesis of AS. In the present study, we examined the effects of paeonol on miRNA-126 (miR‑126) expression, and its ability to inhibit monocyte adhesion to oxidized low-density lipoprotein (ox-LDL)-injured vascular endothelial cells (VECs). VECs were isolated from the rat thoracic aorta and stimulated with ox-LDL (20 mg/l) in the presence of paeonol. We found that miR‑126 had a lower expression in the ox-LDL-injured VECs, and VCAM‑1 was identified as a target gene of miR‑126. Furthermore, paeonol promoted miR‑126 expression and suppressed VCAM‑1 expression at the mRNA and protein level. It also inhibited monocyte adhesion to ox-LDL-injured VECs through the promotion of miR‑126 expression. Furthermore, it was demonstrated that paeonol blocked the activation of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/nuclear factor-κB (NF-κB) signaling pathway by promoting miR-126 expression. Taken together, and to the best of our knowledge, the findings of this study provide the first evidence that paeonol promotes miR‑126 expression to inhibit monocyte adhesion to ox-LDL-injured VECs and block the activation of the PI3K/Akt/NF-κB signaling pathway. Our data suggest that miR‑126 plays a crucial role in vascular inflammation and may be an important therapeutic target in the treatment of AS with the use of paeonol.

Experimental autoimmune encephalomyelitis (EAE) is characterized by demyelination of the central nervous system. Emodin is an anthraquinone derivative with comprehensive anti-inflammatory, anti-cancer, and immunomodulatory effects and is widely used in the treatment of inflammatory, tumor, and immune system diseases. However, none of the clinical or experimental studies have explored the therapeutic efficacy of emodin in EAE/multiple sclerosis (MS). Thus, we evaluated the protective effect of emodin on EAE mediated via inhibition of microglia activation and inflammation. Wild-type mice were randomly divided into the normal control, EAE, low-dose emodin, and high-dose emodin groups. Clinical scores and pathological changes were assessed 21 days after immunization. The network pharmacology approach was used to elucidate the underlying mechanisms by using an online database. Molecular docking, polymerase-chain reaction tests, western blotting, and immunofluorescence were performed to verify the network pharmacology results. An in vivo experiment showed that high-dose emodin ameliorated clinical symptoms, inflammatory cell infiltration, and myelination. Pharmacological network analysis showed AKT1 was the main target and that emodin played a key role in MS treatment mainly via the PI3K–Akt pathway. Molecular docking showed that emodin bound well with PI3K, AKT1, and NFKB1. Emodin decreased the expression of phosphorylated(p)-PI3K, p-Akt, NF-κB, and myeloid differentiation factor 88 and the levels of markers (CD86 and CD206) in M1- and M2-phenotype microglia in EAE. Thus, the emodin inhibited microglial activation and exhibited anti-inflammatory and neuroprotective effects against EAE via the Myd88/PI3K/Akt/NF-κB signalling pathway. In conclusion, emodin has a promising role in EAE/MS treatment, warranting further detailed studies.

Based on emerging evidence linking vitamin homeostasis to inflammatory bowel disease, this study investigated the causal role and therapeutic potential of folate in ulcerative colitis. By employing Mendelian randomization and experimental models, we demonstrated that folate supplementation markedly attenuated colitis severity, suppressed inflammatory responses, and restored the structure and function of the epithelial barrier. Mechanistically, folate acts through inhibition of the PI3K/AKT/NF-κB/MLCK/MLC2 signaling axis, leading to improved barrier integrity and reduced mucosal inflammation. These findings establish folate not only as a protective nutrient but also as a potential therapeutic agent, supporting its use in clinical nutritional strategies for ulcerative colitis management. Vitamin homeostasis plays a critical role in inflammatory bowel disease management, yet the protective mechanisms and clinical utility of specific vitamins remain incompletely characterized. Within this context, a two-sample Mendelian randomization analysis leveraging genetic instruments for measuring circulating vitamin levels identified folate as a protective factor against ulcerative colitis (UC). To validate these findings, a DSS-induced colitis model was established with serial serum folate measurements. Therapeutic folate supplements were subsequently administered, followed by a comprehensive evaluation of epithelial barrier modulation through in vivo and recombinant TNF-α/IFN-γ-induced in vitro models. This included assessment of junctional proteins, ultrastructural analysis by transmission electron microscopy, and functional quantification of barrier integrity using transepithelial electrical resistance with paracellular permeability assays in epithelial monolayers. Molecular mechanisms were investigated through RNA sequencing complemented by immunoblot validation of key pathway components. The results demonstrated decreased serum folate levels in DSS-induced colitis mice, whereas folate supplementation ameliorated disease severity and attenuated intestinal inflammation and histopathological damage. Crucially, folate restored epithelial barrier structural integrity and function both in vivo and in vitro. Mechanistically, folate mediated barrier restoration through suppression of the PI3K/AKT/NF-κB/MLCK/MLC2 signaling axis. Collectively, the results of this study provide mechanistic insights that support the use of folate as an active therapeutic molecule in patients with UC.

Acute renal injury (AKI) has a high incidence rate and mortality, but current treatment methods are limited. As a kind of nanomaterial with enzyme-like activity, nanozyme has shown outstanding advantages in treating AKI according to recent reports. Herein, we assess the potential of manganese-based nanozymes (MnO2–BSA NPs) with excellent biosafety in effectively alleviating AKI. Our findings in vitro and in vivo reveal that MnO2–BSA NPs exert regulatory effects on oxidative stress, inflammation, and apoptosis. These effects are mediated through activation of the Nrf2/HO-1 and PI3K/Akt/NF-κB pathways. Notably, it was observed that the cytoprotective effect of MnO2–BSA NPs is abrogated upon inhibition of Nrf2 expression, highlighting the important role of this transcription factor in cellular protection. In summary, the study demonstrates the protective effect of MnO2–BSA NPs in AKI and provides the molecular mechanisms involved, which can contribute to the advancement of potential therapeutic interventions for nanozyme-based treatments.

Chuanxiong rhizoma (CX) has been utilized for centuries as a traditional herb to treat blood stasis syndromes. However, the pharmacological mechanisms are still not completely revealed. This research was aimed at exploring the molecular mechanisms of CX treatment for thrombosis. Network pharmacology was used to predict the potential anti-thrombosis mechanism after correlating the targets of active components with targets of thrombosis. Furthermore, we verified the mechanism of using CX to treat thrombosis via molecular docking and in vitro experiments. Network pharmacology results showed that a total of 18 active ingredients and 65 targets of CX treatment for thrombosis were collected, including 8 core compounds and 6 core targets. We revealed for the first time that tissue factor (TF) had a close relationship with most core targets of CX in the treatment of thrombosis. TF is a primary coagulation factor in physiological hemostasis and pathological thrombosis. Furthermore, core components of CX have strong affinity for core targets and TF according to molecular docking analysis. The in vitro experiments indicated that Ligustilide (LIG), the representative component of CX, could inhibit TF procoagulant activity, TF mRNA and protein over-expression in a dose-dependent manner in EA.hy926 cells through the PI3K/Akt/NF-κB signaling pathway. This work demonstrated that hemostasis or blood coagulation was one of the important biological processes in the treatment of thrombosis with CX, and TF also might be a central target of CX when used for treating thrombosis. The inhibition of TF might be a novel mechanism of CX in the treatment of thrombosis.Keywords:Chuanxiong rhizoma;tissue factor;anti-thrombosis;network pharmacology;ligustilide;PI3K/Akt/NF-κB signaling pathway
