Buyang Huanwu Decoction promotes neurorepair after spinal cord injury through a Lactobacillus johnsonii–indole-3-lactic acid–AhR–PI3K/Akt axis

Dong Jinwang,Cao Yang,Chen Xiujin,Xie Tao,Zhang Xiaobo,Zhao Qingpeng,Shi Cunhu,Miao Qiangqiang,Xu Zhengwei,Yan Liang,Dong Liang

Background Spinal cord injury (SCI) induces gut microbiota dysbiosis, which significantly affects recovery. Buyang Huanwu Decoction (BHD), a traditional Chinese medicine formula, has shown therapeutic effects on SCI. Although BHD is known to modulate gut microbiota, whether its benefits are mediated through the gut–spinal cord axis remains unclear. Methods A rat SCI model was established. BHD was administered orally, and fecal microbiota transplantation (FMT) from BHD-treated rats (BHD-FMT) was performed to assess neuroprotective and gut-protective effects. Behavioral testing, histology, and immunofluorescence evaluated motor recovery, inflammation, and neuroregeneration. Gut microbiota profiling was performed using 16S rDNA sequencing and metagenomics, while targeted metabolomics quantified tryptophan metabolites. Transcriptomics validated key pathways, and a microbiota–metabolite–signaling network was constructed. Results BHD significantly improved motor function, reduced spinal inflammation, and promoted neuronal survival and axonal regeneration. It restored gut function, reduced colonic inflammation, and enhanced ZO-1 and Occludin expression, which were further confirmed by FMT. BHD-FMT reshaped the gut microbiota and enriched Lactobacillus johnsonii , which correlated positively with recovery. Metabolomics showed increased tryptophan metabolites, including indole-3-lactic acid (ILA) and indole-3-propionic acid (IPA), with ILA strongly associated with functional improvement. Transcriptomic analysis and Western blot validation demonstrated that BHD-FMT activated the AhR–PI3K/Akt pathway, which was suppressed by an AhR antagonist. Conclusion BHD promotes neuroregeneration after SCI by reshaping gut microbiota and enhancing tryptophan metabolism, potentially exerting its effects through the L. johnsonii –ILA–AhR–PI3K/Akt network. These findings reveal a gut–spinal cord axis–mediated mechanism of BHD and highlight microecological targets for SCI therapy.

Layered Double Hydroxide-Loaded Dl-3-n-Butylphthalide Alleviates Renal Ischemia-Reperfusion Injury by Regulating the PI3K-AKT-Nrf2 Signaling Pathway

Yan Yan,Ke Wang,Li Ren,Jun-jie Ma,Xing-chun Zhu,Hao-feng Ding,Jia-xin Chu,Zhi-gao Zhu,Jing-yi Xia,Yi Xia,Yuan Xu,Meng-han He,Wen-rui Wang,Cong-li Zhang

Purpose This study aims to address the issues that limit the clinical application of Dl-3-n-butylphthalide (NBP) due to its poor water solubility and low bioavailability, and to explore its therapeutic potential in renal ischemia-reperfusion (I/R) injury. We attempted to utilize layered double hydroxide (LDH) to construct a novel nano-drug delivery system to enhance the stability and efficacy of NBP, and to deeply investigate its potential mechanism of action.Methods By loading NBP onto LDH, LDHs-NBP nanocomplexes were successfully constructed. Subsequently, the effects of LDHs-NBP on renal function, tissue pathology, cell apoptosis, oxidative stress and mitochondrial function were systematically evaluated in rat renal ischemia-reperfusion injury models and HK-2 cell hypoxia/reoxygenation models. The molecular mechanism of the PI3K-AKT-Nrf2 signaling pathway was analyzed through immunohistochemistry and Western Blot.Results The experimental results show that the drug loading capacity of LDHs-NBP nanocomplexes is 24.26%. Compared with pure NBP, LDHs-NBP more effectively improve renal function in rats, reduces serum creatinine (SCr) and blood urea nitrogen (BUN), decreases inflammatory infiltration and structural damage in renal tissues, and exhibits stronger antioxidant capacity—evidenced by decreased malondialdehyde (MDA) levels and increased superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) activities. At the cellular level, LDHs-NBP significantly inhibits apoptosis and ROS production in HK-2 cells, alleviates mitochondrial dysfunction, and its protective effect is closely associated with activation of the PI3K-AKT-Nrf2 signaling pathway.Conclusion This study successfully constructed an NBP nano-complex based on LDH, and confirmed that LDHs-NBP has significant therapeutic advantages in renal ischemia-reperfusion injury. The mechanism may be related to the activation of the PI3K-AKT-Nrf2 pathway. This study provides experimental evidence for the application of LDHs-NBP in the treatment of renal ischemia-reperfusion injury, and shows a promising translational prospect and clinical value.

A Plant-Derived Flavonoid, Isobavachin, Promotes Osteogenesis and Alleviates Glucocorticoid-Induced Osteoporosis via Modulation of the ESR1-PI3K/Akt Signaling Pathway

Jingran Cui,Xuting Song,Heran Liu,Zhenhai Cui,Mengmeng Sun,Min He,Meiying Jin

Background: Glucocorticoid-induced osteoporosis (GIOP) is marked by impaired osteogenesis and reduced bone formation. Isobavachin (IBA), a flavonoid from Psoralea corylifolia, shows multiple potentials in anti-inflammatory and bone metabolism regulations, but its effects against GIOP remain unclear. This study investigated the osteoprotective effects and potential mechanism of IBA using zebrafish GIOP model. Methods: osteoprotective effects of IBA was assessed by fluorescence imaging in a prednisolone-induced zebrafish model, following with osteogenic gene expressions measured by RT-qPCR. Potential targets and pathways of IBA was filtered and predicted by network pharmacology, molecular docking, and molecular dynamics (MD) simulations, and finally validated with a pharmacological rescue experiment using a PI3K-specific inhibitor. Results: IBA improved bone mineralization and upregulated osteogenesis-related genes. Network pharmacology identified the PI3K-Akt pathway as a key pathway, with ESR1, GSK3B, MTOR, and CCND1 as core targets. PI3K inhibition attenuated the osteoprotective effects of IBA and suppressed downstream osteogenic gene expression. Conclusions: IBA alleviates GIOP by modulating the ESR1-associated PI3K-Akt signaling pathway and may serve as a multi-target therapeutic candidate for osteoporosis.

iRGD-modified 3D exosomes delivered miR-99b-5p induces ferroptosis to inhibit colorectal cancer progression by regulating FGFR3/PI3K/AKt pathway

Li Xiao-huan,Lian Fu-wei,Lv Feng,Luo Xiao-Ling,Hu Bang-li,Zhang Li-tu,Ning Shu-fang

Background Mesenchymal stem cells (MSCs)-derived exosomes present great potential as nanocarriers for targeted drug delivery. Moreover, the therapeutic efficacy of exosomes can be substantially enhanced through functional modifications and the incorporation of bioactive molecules. Methods In this study, the MSCs were cultured under two-dimensional (2D) and three-dimensional (3D) cell culture conditions. The culture supernatants were collected for isolating exosomes. The characteristics and yields of exosomes from 2D and 3D cultures were detected by nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), western blot analysis, and bicinchoninic acid (BCA) assay. Subsequently, 3D exosomes were loaded with miR-99b-5p and modified with iRGD peptide were formed into a new engineered exosome, designated as iRGD-Exo-miR-99b-5p. The effects of these engineered exosomes on the progression of colorectal cancer (CRC) were assessed through a series of in vivo and in vitro experiments. Results The 3D-cultured MSCs exhibited a higher yield of exosomes and enhanced uptake by CRC cells. Further in vitro experiments demonstrated that 3D-exosomes loaded with miR-99b-5p effectively inhibit the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of CRC cells. Results from a xenograft tumor model indicate that iRGD-modified exosomes were significantly enriched at tumor sites. Furthermore, exosomes modified with iRGD and loaded with miR-99b-5p were employed for CRC treatment, resulting in substantial tumor growth inhibition and enhanced the chemotherapy efficacy of 5-fluorouracil (5-FU) in vivo, without inducing notable toxicity or side effects. Mechanistically, exosome-mediated delivery of miR-99b-5p downregulated FGFR3 expression, thereby inhibiting the activation of the PI3K/AKt signaling pathway and promoting ferroptosis, ultimately attenuating CRC progression. Conclusions Collectively, iRGD-modified 3D exosomes loaded with miR-99b-5p were able to specifically target tumor sites, thereby significantly suppressing CRC growth through the induction of ferroptosis via regulating the FGFR3/PI3K/AKt signaling pathway. These findings suggest that functional engineering and bioactive loading of 3D-exosomes derived from MSCs represent a promising strategy for targeted cancer therapy. Graphical

Steamed Panax notoginseng Saponins Ameliorate Cyclophosphamide-Induced Anemia by Attenuating Gut-Liver Injury and Activating the cAMP/PI3K/AKT Signaling Pathway

Cuiping Xu,Hao Cui,Qionglian Fang,Pengfei Tu,Xiuming Cui

Background: Steamed Panax notoginseng saponins (SPNSs) can alleviate cyclophosphamide-induced anemia. However, the hepatointestinal effects of SPNSs and their role in ameliorating cyclophosphamide-induced anemia remain unexplored. Objective: To elucidate the hepatointestinal effects of SPNSs and their role in ameliorating cyclophosphamide-induced anemia. Methods: Blood samples were collected and analyzed on days 7 and 14. Liver tissues and small intestinal villi structures were observed via HE staining. Liver and colon content metabolites were detected by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Liver proteins were analyzed by using an Orbitrap Astral mass spectrometer. Colon content microbiota composition was assessed via metagenomics. Signaling pathway protein expression was analyzed via Western blotting (WB). Results : SPNSs significantly increased the red blood cell (RBC) count and hemoglobin (HGB) level by day 14 and alleviated hepatointestinal damage. Hepatic metabolomics revealed: the most abundant metabolites were fatty acids and stachyose on day 7 and amino acid and arachidonic acid derivatives on day 14. KEGG analysis implicated cAMP signaling. Proteomics revealed upregulated immune-related proteins and enhanced PI3K pathway activity (WB-validated). Colon content metabolomics showed increased daidzein, 3-(2,5-dimethoxyphenyl) propanoic acid, γ-CEHC, and adenosine in SPNS groups on day 14. Metagenomics indicated differential abundances of Heminiphilus faecis , Phocaeicola sartorii , and s-bacterium_J10.2018 on day 14. Multiomics integration demonstrated significant correlations between hepatic metabolites, hematopoietic proteins, colon content metabolites, and probiotic bacteria. Conclusions: SPNS alleviates cyclophosphamide-induced hepato-intestinal injury in anemic mice by modulating the gut microbiota and enhancing hepato-intestinal immune defense. Additionally, SPNSs ameliorate anemia in cyclophosphamide-treated mice by activating the cAMP/PI3K/AKT pathway, promoting hepatocyte proliferation, and increasing hematopoietic protein expression.

Chen Lin,Jiang Qihong,Lu Hongling,Jiang Chenkai,Hu Wenjun,Yu Shaofang,Xiang Xingwei,Tan Chin Ping,Feng Yongcai,Zhang Jianfang,Li Mingqian,Shen Guoxin

Type 2 diabetes mellitus (T2DM) is a metabolic disease characterized by hyperglycemia. The aim of this work was to investigate the effect of sciadonic acid (SA) on disorders of glucolipid metabolism and intestinal flora imbalance and to further investigate its potential molecular mechanism of anti-diabetes. The experimental data indicated that SA could alleviate hyperlipidemia, insulin resistance, oxidative stress, the inflammatory response, repair liver function damage, and promote glycogen synthesis caused by T2DM. SA could also activate the PI3K/AKT/GLUT-2 signaling pathway, promote glucose metabolism gene expression, and maintain glucose homeostasis. Furthermore, 16S rRNA analysis revealed that SA could reduce the Firmicutes/Bacteroidota (F/B) ratio; promote norank_f__Muribaculaceae, Allobaculum, Akkermansia, and Eubacterium_siraeum_group proliferation; increase the levels of major short-chain fatty acids (SCFAs), such as acetic acid, propionic acid, and butyric acid; and maintain the homeostasis of the intestinal flora. In conclusion, these results suggested that SA could reshape the structural composition of intestinal microbes, activate the PI3K/AKT/GLUT2 pathway, improve insulin resistance, and decrease blood glucose levels.

Design, synthesis and biological evaluation of anilide (dicarboxylic acid) shikonin esters as antitumor agents through targeting PI3K/Akt/mTOR signaling pathway

Yingying Ma,Xiaorong Yang,Hongwei Han,Zhongling Wen,Minkai Yang,Yahan Zhang,Jiangyan Fu,Xuan Wang,Tongming Yin,Guihua Lu,Jinliang Qi,Hongyan Lin,Xiaoming Wang,Yonghua Yang

Triple-negative breast cancer (TNBC) has an unfavorable prognosis attribute to its low differentiation, rapid proliferation and high distant metastasis rate. PI3K/Akt/mTOR as an intracellular signaling pathway plays a key role in the cell proliferation, migration, invasion, metabolism and regeneration. In this work, we designed and synthesized a series of anilide (dicarboxylic acid) shikonin esters targeting PI3K/Akt/mTOR signaling pathway, and assessed their antitumor effects. Through three rounds of screening by computer-aided drug design method (CADD), we preliminarily obtained sixteen novel anilide (dicarboxylic acid) shikonin esters and identified them as excellent compounds. CCK-8 assay results demonstrated that compound M9 exhibited better antiproliferative activities against MDA-MB-231, A549 and HeLa cell lines than shikonin (SK), especially for MDA-MB-231 (M9: IC 50  = 4.52 ± 0.28 μM; SK: IC 50  = 7.62 ± 0.26 μM). Moreover, the antiproliferative activity of M9 was better than that of paclitaxel. Further pharmacological studies showed that M9 could induce apoptosis of MDA-MB-231 cells and arrest the cell cycle in G2/M phase. M9 also inhibited the migration of MDA-MB-231 cells by inhibiting Wnt/β-catenin signaling pathway. In addition, western blot results showed that M9 could inhibit cell proliferation and migration by down-regulating PI3K/Akt/mTOR signaling pathway. Finally, a three-dimensional quantitative structure–activity relationship (3D-QSAR) model was also constructed to provide a basis for further development of shikonin derivatives as potential antitumor drugs through structure–activity relationship analysis. To sum up, M9 could be a potential candidate for TNBC therapy.

Hydrazinocurcumin and 5-fluorouracil enhance apoptosis and restrain tumorigenicity of HepG2 cells via disrupting the PTEN-mediated PI3K/Akt signaling pathway

Ye Zhou,Meng Zhang,Zhilei Zhang,Yuming Jia,Chong Zhang,Li Peng

Hydrazinocurcumin (HZC), a curcumin analogue, serves as a tumor suppressor in breast cancer and lung cancer. In this study, we investigate the role and mechanism of HZC in regulating HepG2 cell apoptosis and tumorigenicity, and its synergistic effects with 5-fluorouracil (5-Fu). HepG2 cells were treated with HZC and/or 5-Fu to analyze the possible synergistic effects on cell proliferation, apoptosis and cell cycle distribution in vitro using EdU staining, Hoechst staining and flow cytometry, respectively. For mechanistic investigation we used pic, a phosphatase and tensin homolog (PTEN) inhibitor, and in other studies assessed the expression pattern of PTEN and PI3K/Akt signaling pathway-related genes. Additionally, we tested in vivo effects of HZC and 5-Fu treatment on growth of HepG2 cell tumors in nude mice. We found that HZC or 5-Fu induced apoptosis and repressed proliferation of HepG2 cells by upregulating the expression of PTEN and disrupting the PI3K/Akt signaling pathway activation. Moreover, HZC had a higher pro-apoptotic effect than 5-Fu. HZC and 5-Fu induced HepG2 cell apoptosis and inhibited their tumorigenicity in vivo . Inhibition of PTEN expression activated the PI3K/Akt signaling pathway and reversed the protective effects of HZC or 5-Fu. Thus, HZC and 5-Fu increase PTEN, which blocks the PI3K/Akt signaling pathway, ultimately inducing HepG2 cell apoptosis. Importantly, the synergistic combination of HZC and 5-Fu may present promising strategy for the treatment of HCC.

Selenomethionine protects oxidative-stress-damaged bone-marrow-derived mesenchymal stem cells via an antioxidant effect and the PTEN/PI3K/AKT pathway

Yiming Li,Yi He,Guanhui Chen,Ziqing Huang,Chen Yi,Xiliu Zhang,Feilong Deng,Dongsheng Yu

abstract Dental implant surgery is currently a routine therapy for the repair of missing dentition or dentition defects. Both clinical and basic research have elucidated that oxidative stress caused by the accumulation of reactive oxygen species (ROS) for various reasons impairs the process of osteointegration after dental implantation. Therefore, the osteogenic micro-environment must be ameliorated to decrease the damage caused by oxidative stress. Selenomethionine (SEMET) has been reported to play an important role in alleviating oxidative stress and accelerating cell viability and growth. However, it remains unclear whether it exerts protective effects on bone-marrow-derived mesenchymal stem cells (BMSCs) under oxidative stress. In this study, we explored the influence of selenomethionine on the viability and osteogenic differentiation of BMSCs under oxidative stress and the underlying mechanisms. Results showed that 1 μM selenomethionine was the optimum concentration for BMSCs under H 2 O 2 stimulation. H 2 O 2 -induced oxidative stress suppressed the viability and osteogenic differentiation of BMSCs, manifested by the increases in ROS production and cell apoptosis rates , and by the decrease of osteogenic differentiation-related markers. Notably, the aforementioned oxidative damage and osteogenic dysfunction induced by H 2 O 2 were rescued by selenomethionine. Furthermore, we found that the PTEN expression level was suppressed and its downstream PI3K/AKT pathway was activated by selenomethionine. However, when PTEN was stimulated, the PI3K/AKT pathway was down-regulated, and the protective effects of selenomethionine on BMSC osteogenic differentiation diminished, while the inhibition of PTEN up-regulated the protective effects of selenomethionine. Together, these results revealed that selenomethionine could attenuate H 2 O 2 -induced BMSC dysfunction through an antioxidant effect, modulated via the PTEN/PI3K/AKT pathway, suggesting that selenomethionine is a promising antioxidant candidate for reducing oxidative stress during the process of dental implant osteointegration.

Apigenin Suppresses the Warburg Effect and Stem-like Properties in SOSP-9607 Cells by Inactivating the PI3K/Akt/mTOR Signaling Pathway

Yihua Shi,Kai Lian,Jiguang Jia

Osteosarcoma (OS) is a prevalent primary malignant bone tumor that commonly occurs in children and adolescents. Apigenin (4′,5,7-trihydroxyflavone) is one of the most researched phenolic compounds that exhibits antitumor effects in several cancers. The aim of the current study was to investigate the effect and underlying mechanisms of apigenin on OS. To address this, OS cells (SOSP-9607) were treated with different concentrations of apigenin. The proliferation, migration, invasion, stem-like properties, and Warburg effect of apigenin-treated OS cells were evaluated. Apigenin was found to suppress the proliferation of SOSP-9607 cells and inhibit epithelial-mesenchymal transition, as indicated by decreased number of migrated and invaded cells, decreased protein expression of vimentin, and increased protein expression of E-cadherin. Additionally, apigenin suppressed tumorsphere formation and reduced the proportion of SOSP-9607 cells with positive expression of the stem cell-related markers Nanog and OCT-4. Apigenin inhibited the Warburg effect in SOSP-9607 cells, as demonstrated by decreased glucose and lactic acid levels, increased citrate and ATP levels, and downregulation of GLUT1, HK1, and LDHA, which are metabolism-related enzymes related to the Warburg effect. Moreover, apigenin inhibited the phosphorylation of PI3K, Akt, and mTOR in SOSP-9607 cells. Collectively, these results indicate that apigenin suppresses the Warburg effect and stem-like properties in SOSP-9607 cells, which may be mediated by PI3K/Akt/mTOR signaling, thus, providing a novel strategy for OS treatment.

Qilin Pill Exerts Therapeutic Effect on Resection-Induced Premature Ovarian Insufficiency Rats by Inhibiting the MAPK and PI3K-AKT Signaling Pathways

Debao Li,Yuling Jia,Yiwen Hou,Dingshi Chen,Chiyang Zheng,Lifen Chen,Li Zhou,Zuyue Sun

Background The Qilin pill (QLP) is a traditional Chinese compound prescription comprising 15 herbs that has demonstrated significant therapeutic effects on premature ovarian insufficiency (POI) in recent years. However, a pharmacological evaluation of QLP on ovarian function remains to be conducted, and the key mechanism of QLP treatment on POI is unclear.Methods Premature ovarian insufficiency rats were established by bilateral partial ovariectomy. The model rats were administrated with low (QLP-L), medium (QLP-M) and high (QLP-H) doses of QLP for 4 weeks to evaluate the ovarian function in terms of estrous cycle, hormone level, and follicle count. The mechanism of QLP in the treatment of POI was systematically explored by network pharmacology, and expression levels of the MAPK and PI3K-AKT signaling pathways were verified by Western blotting and molecular docking.Results The rat model of resection-induced POI was successfully established, and QLP could significantly recover the estrous cycle, decrease serum FSH levels, and decelerate follicle depletion after 4 weeks of administration. The optimal dose of QLP in the experiment was preliminarily determined to be 0.9 g/kg. Based on the network pharmacology methods, we constructed the compound-target network and protein protein interaction (PPI) network of QLP for the treatment of POI. The experimental verification of the enrichment analysis showed that QLP inhibited the MAPK and PI3K-AKT signaling pathways, and the key compounds and key targets involved were verified by molecular docking.Conclusion QLP exerted significant therapeutic effects on resection-induced POI rats, and this was achieved by the inhibition of the MAPK and PI3K-AKT signaling pathways. This study is the first to systematically investigate the effects and mechanism of QLP on POI rats, which will provide valuable guidance in clinic.

Lonicera rupicola Hook.f.et Thoms flavonoids ameliorated dysregulated inflammatory responses, intestinal barrier, and gut microbiome in ulcerative colitis via PI3K/AKT pathway

Congcong Li,Lu Wang,Juebo Zhao,Yucai Wei,Shuo Zhai,Min Tan,Kuikui Guan,Zhihong Huang,Chaoxi Chen

Background Lonicera rupicola Hook.f.et Thoms (LRH) is used as a customary medicinal herb in Tibetans. And LRH flavonoids have excellent anti-inflammatory and antioxidant pharmacological activities. However, the specific effects of LRH and its mechanism remain unknown, and there is a deficiency of systematic research, leading to the waste of LRH as a medicinal resource. Purpose In this study, in an attempt to rationalize the development and utilization of Tibetan herbal resources, the therapeutic efficacy and the underlying molecular mechanisms of LRH flavonoids on dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) were investigated, establishing the favorable basis for the pharmacodynamic material basis of LRH and providing a scientific basis for the discovery of new drugs for the treatment of UC. Methods Firstly, ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) was used for identification and detection of the flavonoid components of LRH. Meanwhile, their potential targets, biological functions and signaling pathways were predicted with the assistance of network pharmacology analysis. Subsequently, pharmacological efficacy of LRH were evaluated by body weight loss, colon length, disease activity index (DAI), histology observation and the expression levels of inflammatory mediators, messenger RNA (mRNA) and tight junction proteins. Moreover, in the present investigation, we also profiled the gut microbiome via high-throughput sequencing of the V3 - V4 region of 16S ribosomal DNA (rDNA) for bacterial community composition and diversity by Illumina MiSeq platforms. Finally, the key regulatory proteins in the PI3K/AKT pathways were measured to investigate their underlying molecular mechanisms. Results A total of 37 LRH flavonoid components were identified and detected by UPLC-MS/MS, and 12 potential active components were obtained after screening. 137 of their common targets with UC were further predicted . GO and KEGG pathway enrichment analysis and molecular docking experiments demonstrated that LRH flavonoids could interfere with UC through "multi-component-multi-target-multi-pathway". In the animal experiments, LRH flavonoids could significantly attenuate UC as demonstrated by reducing the body weight loss and DAI, restoring colon length, decreasing oxidative stress, and improving the intestinal epithelial cell barrier. The mRNA and proteins expression levels of inflammatory mediators were returned to dynamic balance following LRH flavonoids treatment. 16S rDNA sequence analysis indicated that LRH flavonoids promoted the recovery of gut microbiome. And the PI3K/AKT pathway was significantly suppressed by LRH flavonoids. Conclusions LRH flavonoids exhibited multifaceted protective effects against DSS-induced UC in mice through mitigating colon inflammation and oxidative stress, restoring epithelial barrier function, and improving the gut microenvironment potentially through modulation of the PI3K/AKT pathway. This finding demonstrated that LRH flavonoids possessed great potential for becoming an excellent drug for the treatment of UC.
