Cabazitaxel suppresses the proliferation and promotes the apoptosis and radiosensitivity of castration-resistant prostate cancer cells by inhibiting PI3K/AKT pathway

Zheng Xu,Luwei Xu,Yuzheng Ge,Hongbin Sun,Jiageng Zhu,Quanliang Dou,Ruipeng Jia

Background: Cabazitaxel has been applied to the treatment of castration-resistant prostate cancer (CRPC), but the molecular mechanism remained to be fully understood. Methods: After treatment with Cabazitaxel alone or in combination with ionizing radiation (IR), CRPC cell viability, proliferation and apoptosis were determined by Cell Counting Kit-8 (CCK-8) assay, colony formation, and flow cytometry, respectively. Tumor volume was measured after the establishment of animal xenograft model. Relative expressions of proteins related to apoptosis (B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), and cleaved caspase 3) and phosphoinositide 3-kinase (PI3K)/AKT pathway were measured by Western blot, and the phosphorylated-PI3K/PI3K and p-AKT/AKT ratios were determined as well. Results: Cell viability and proliferation were suppressed, and apoptosis was promoted in CRPC cells after Cabazitaxel treatment alone, accompanied with upregulated expressions of Bax and cleaved caspase 3 and downregulated Bcl-2 expression. Also, a single treatment with Cabazitaxel resulted in suppression of PI3K/AKT pathway activation, along with downregulated expressions of p-PI3K and p-AKT and a reduced ratio of p-PI3K/PI3K to p-AKT/AKT. Meanwhile, Cabazitaxel enhanced the effects of IR on suppressing survival and promoting apoptosis in CRPC cells through downregulating Bcl-2 and upregulating Bax and cleaved caspase 3. However, Cabazitaxel suppressed IR-induced PI3K/AKT pathway activation via downregulating p-PI3K and p-AKT, leading to a reduced ratio of p-PI3K/PI3K to p-AKT/AKT. Furthermore, Cabazitaxel further promoted the effects of IR on suppressing tumor growth in vivo . Conclusion: Cabazitaxel inhibited the proliferation and promoted the apoptosis and radiosensitivity of CRPC cells, which is related to the suppression of PI3K/AKT pathway, providing a therapeutic method for CRPC in clinical practice.

Chrysophanic acid shifts the differentiation tendency of BMSCs to prevent alcohol-induced osteonecrosis of the femoral head

Hongping Yu,Pei Liu,Daoyu Zhu,Junhui Yin,Qianhao Yang,Yigang Huang,Yixuan Chen,Changqing Zhang,Youshui Gao

Objectives Osteonecrosis of the femoral head (ONFH), largely caused by alcohol abuse, is a refractory bone disease characterized by the impaired capacity of osteogenic differentiation of bone mesenchymal stem cells (BMSCs), as well as the disordered adipocyte accumulation. Chrysophanic acid (CPA) is a natural anthraquinone which has lipid regulation and bone protection capacity. The aim of this study was to reveal the potential function of CPA and the underlying mechanisms for the alcohol-induced ONFH. Materials and Methods The effects of alcohol and CPA on BMSCs were investigated by cell proliferation, induced differentiation assays and immunofluorescent staining. Meanwhile, the function of PI3K/AKT and AMPK pathway was investigated in the process of osteogenic and adipogenic differentiation, respectively. Furthermore, we established the rat model of alcohol-induced ONFH to reveal the pharmacotherapeutic effect of CPA in vivo using radiographical and histopathological methods. Results In vitro, alcohol significantly inhibited the proliferation and osteogenic differentiation of BMSCs but stimulated the adipogenic differentiation. However, CPA could counteract the anti-osteogenesis of alcohol partly via PI3K/AKT pathway and retard the promotion of alcohol-induced adipogenesis via AMPK pathway. In vivo, radiographical and histopathological findings showed that CPA could alleviate alcohol-induced ONFH and substantially restore the bone volume. Conclusions We demonstrated that CPA ameliorated alcohol-induced ONFH possibly via regulating the differentiation tendency of BMSCs. Hence, CPA may become a beneficial herb extract to alleviate alcohol-induced ONFH.

Hydrogen sulfide improves depression-like behaviors in CUMS-induced mice by regulating autophagy

Zhaoke Ling,Qingqing Kong,Zhiqiang He,Xin Hao,Ruiyao Liu,Jie Liu,Yushi Wang,Jiao Liu,Wenlong Du,Yi Liu

The pathogenesis of depression is associated with synaptic impairment and dysfunction in autophagy processes. Mendelian randomization (MR) analysis revealed that six GWAS IDs revealed a significant association between Beclin-1 levels and depression risk. Besides, all SNPs had a positive effect on depression risk. Analyzing neurons from depressed individuals using single-cell RNA sequencing (scRNA-seq) uncovered decreased expression of AKT, mTOR, and genes linked to synaptic plasticity. The activation of the PI3K/AKT/mTOR signaling has been demonstrated to control autophagy and have a protective effect on the nervous system. Hydrogen sulfide (H 2 S) is an endogenous gasotransmitter that can potentially treat various neurological disorders by improving neuronal synaptic plasticity. However, whether H 2 S regulates autophagy through PI3K/AKT/mTOR signaling, improves neuronal synaptic plasticity damage, and plays an antidepressant role is unclear. Our current research revealed that the reduction in the expression of p-PI3K, p-AKT, and p-mTOR proteins increase in neuronal autophagy activity and decline synaptic plasticity in mice with depression induced by chronic unpredictable mild stress (CUMS). Treatment with the exogenous hydrogen sulfide donor NaHS for one day and continuous treatment for one week improved the depression-like behaviors in the mice. Compared with those after one day of NaHS treatment, the above protein expression levels were restored and maintained, and the antidepressant effect was more significant after one week of continuous treatment with NaHS. Moreover, the PI3K inhibitor LY294002 was used to demonstrate that NaHS suppresses autophagy through activating the PI3K/AKT/mTOR signaling and ameliorates synaptic plasticity impairments. This study provides novel insights into the antidepressant mechanisms of H 2 S, highlighting its antidepressant therapeutic potential.

Metabolomics and integrated network pharmacology analysis revealed multi-targeted anti-cancer effect of FuZhengXiaoJi Decoction against non-small cell lung cancer

Xinyuan Jiang,Zhiyong Xu,Huan Wang,Jiangnan Zhao,Nueraili Maihemuti,Sujing Jiang,Mingshu Xiao,Kaiyue Zhang,Sibei Liang,Yueli Shi,Kai Wang

Background and purpose : As a malignant tumor characterized by a dismal prognosis and a high mortality rate, non-small cell lung cancer (NSCLC) presents significant challenges in contemporary treatment. These challenges include drug resistance and side effects, which severely hamper the effectiveness of current therapeutic strategies. An increasing number of herbal formulas have been utilized in antitumor therapy, owing to their cost-effectiveness, beneficial efficacy, and additional advantages. FuZhengXiaoJi Decoction (FZXJD), a cancer-treating formula, has been successfully applied in NSCLC clinical treatment, but the underlying mechanism remains elusive. Therefore, this paper integrated multiple analytical methods, including network pharmacology, metabolomics, biological approaches, and molecular docking to clarify how FZXJD suppresses NSCLC. Methods : This study assessed the anti-NSCLC efficacy of FZXJD using in vitro assays and lung cancer xenograft models, and the primary components and potential mechanisms of FZXJD inhibition of NSCLC were identified by high-performance liquid chromatography (HPLC) and network pharmacology. Subsequently, inhibitory mechanisms of FZXJD and its principal effector component oleanolic acid (OA) on NSCLC were explored by molecular docking, as well as biological experiments. Finally, effects of FZXJD on critical metabolic pathways in tumors were further investigated by metabolomics and metabolite enrichment analysis. Results : Inhibition of FZXJD on NSCLC cells was confirmed in vitro experiments. Correspondingly, in vivo experiments revealed that FZXJD impeded tumor progression without obvious toxic side effects. Network pharmacology and molecular docking disclosed that target genes involved in FZXJD’s inhibition of NSCLC were significantly enriched in the PI3K/AKT and ERK/MAPK signaling pathways. Additionally, 14 core genes (HSP90AA1, VEGFA, AKT1, JUN, EGFR, CASP3, ESR1, ERBB2, STAT3, MTOR, SRC, MDM2, CCND1, MAPK3) as well as the main component of the antitumor effect of FZXJD, the OA, were also identified. Biological experiments and molecular docking demonstrated that FZXJD and OA exerted antitumor effects by inhibiting two significant pathways, PI3K/AKT and ERK/MAPK. Metabolomics analysis indicated that FZXJD treatment suppressed glutathione metabolism in vivo. Conclusion FZXJD and its main active ingredient, OA, impede NSCLC progression by inhibiting PI3K/AKT and ERK/MAPK signaling pathways. FZXJD treatment also markedly attenuates glutathione metabolism. This research provides a promising strategy for the application of herbal formulas in NSCLC.

Chenguang Yao,Ting Tan,Jiangning Yan,Zijia Zhao,Romina Onintsoa Diarimalala,Junjie Wang,William Wang,Hanluo Li,Jingbiao Liu,Yanhong Wei,Kanghong Hu

ObjectiveTo develop new Anderson-type polyoxometalates (POMs) with high efficiency and low cytotoxicity, and investigate the effects and mechanisms against lung (A549), cervical (Hela), and breast cancer (MCF7) cell lines.MethodsCytotoxicity assessments on Hela, A549, and MCF-7 tumor cells were tested by MTT assay. Antitumor activities of B1 (vanadium-centered, methyl-modified) and B7 (vanadium-centered, hydroxyl-modified) were detected by apoptosis, scratch, and colony formation assay. The antitumor molecular mechanisms were explored by Western blotting.ResultsThis study synthesized and evaluated twelve Anderson-type compounds which were centered with vanadium, chromium, iron, cobalt, nickel, and copper heteroatoms, modified with methyl and hydroxyl at the side chains. Cytotoxicity assessments revealed that compounds B1 and B7 exhibited superior efficacy, with IC50 values of approximately 7 μmol/L of three cell lines. B1 and B7 inhibited proliferation and migration in these cell lines and induced apoptosis in MCF7 and A549 cells. Mechanistic investigations indicated that B1 induces apoptosis in MCF7 cells by inhibiting the AKT signaling pathway and downregulating the expression of apoptosis-related proteins Bcl-2 and Caspase-9.ConclusionNovel Anderson-type POMs B1 (vanadium-centered, methyl-modified) and B7 (vanadium-centered, hydroxyl-modified) exhibited superior efficacy against tumor cells and induced apoptosis via PI3K/AKT pathway, which provides new theoretical avenues for developing POM-mediated antitumor chemotherapeutic medications.

Therapeutic effects of Ainsliaea fragrans champ. and its active compounds on cervicitis: An integrated approach combining metabolomics, network pharmacology, and experimental validation

Zhengwen Zhang,Zhaojun Wang,Yushun Cui,Min Yao,Jiajian Lu,Mingzhen He,Yulin Feng,JunMao Li

Ethnopharmacological relevance Ainsliaea fragrans Champ. (AFC) , a traditional Chinese medicinal herb with a well-documented history in the management of gynecological disorders, serves as the principal component of several Chinese patent medicines that have demonstrated significant clinical efficacy against cervicitis, endometritis, and pelvic inflammatory disease. However, its specific mechanism of action against cervicitis has not been fully elucidated. Purpose This study aims to determine the therapeutic efficacy and underlying mechanisms of AFC in treating cervicitis, and identifying its key active components. Materials and methods First, an in vivo model of cervicitis was established using a phenolic mucilage solution, while an in vitro LPS induced RAW264.7 cell inflammation model was employed. The therapeutic effects of AFC were evaluated through HE staining, uterine index measurements, RT-qPCR and ELISA. The chemical constituents of AFC were identified using ultra-performance liquid chromatography coupled with UPLC-Q-TOF/MS. Subsequently, cellular metabolomics and network pharmacology were utilized to predict the potential targets, mechanisms, and active components of AFC in treating cervicitis. Finally, the underlying mechanisms and active ingredients were validated using methods such as RT-qPCR, Western blot, and molecular docking. Results Both in vivo and in vitro experiments demonstrated that AFC ameliorated phenol mucilage-induced cervicitis in rats and significantly suppressed the expression of inflammatory factors including IL-6, TNF-α, and IL-1β. UPLC-Q-TOF-MS/MS analysis identified 93 chemical constituents in AFC. Cellular metabolomics revealed 79 differential metabolites, including PGE2 and COX-2, among others. Integrated network pharmacology analysis identified potential targets including IDO1 and COX-2, and enriched signaling pathways such as TLR4 and PI3K/AKT-mTOR. Among the nine candidate compounds screened, luteolin, apigenin, and isorhamnetin ranked as the top three by degree value were hypothesized to be the primary active constituents of AFC against cervicitis. Subsequent experimental validation through RT-qPCR, Western blot, and molecular docking demonstrated that AFC treats cervicitis by modulating the PGE2/COX-2/IDO1-FLG in coordination with the TLR4 and PI3K/AKT-mTOR pathways, with luteolin, apigenin, and isorhamnetin confirmed as the key active compounds. Conclusion AFC exerts its therapeutic effects against cervicitis through coordinated regulation of the PGE2/COX-2/IDO1-FLG in conjunction with the TLR4 and PI3K/AKT-mTOR signaling pathways.

Coptisine regulates PI3K/AKT pathway to block bladder cancer progression: a study based on network pharmacology, in vitro and in vivo assays

Xiaohui Yu,Jie Li,Jiangqiao Zhou

Background Coptisine (COP) is a natural compound extracted from Rhizoma Coptidis , and it represses the malignant biological behaviors of bladder cancer cells. However, the underlying molecular mechanism has not been fully elucidated. The aim of this study was to clarify the downstream mechanism by which COP treats bladder cancer. Materials and methods SwissTargetPrediction, STITCH, SymMap, ETCM, TCMSP, CTD databases were used to collect the related targets of COP. GeneCards, DisGeNET, TTD and OMIM databases were used to obtain the related targets of bladder cancer. A Venn diagram was used to identify the potential targets of COP in bladder cancer treatment. The protein-protein interaction network was constructed using STRING database, and Cytoscape 3.9.0 software was used to screen the hub targets. The binding relationship between COP and the hub targets was verified by molecular docking and molecular dynamics simulation. After the bladder cell lines T24 and BIU-87 were treated with different doses of COP, the regulatory effects of COP on PI3K/AKT pathway were investigated with western blotting. Additionally, the tumor-suppressive properties of COP on bladder cancer cells were validated with tumorigenesis model and metastasis model in nude mice. Results RAC-alpha serine/threonine-protein kinase 1 (AKT1), glycogen synthase kinase 3 beta (GSK3B), caspase-3 (CASP3), tumor necrosis factor (TNF) and cyclin D1 (CCND1) were identified as the main hub targets of COP in bladder cancer treatment. PI3K/AKT pathway was predicted to be a crucial pathway regulated by COP. The binding affinities between COP and AKT1, GSK3B, CASP3, TNF and CCND1 were high. COP treatment markedly repressed the phosphorylation level of ERK1/2, AKT1, PI3K p85 and mTOR in T24 and BIU-87 cells, and repressed the tumorigenesis and lung/liver metastasis of T24 cells in vivo. Conclusion COP may be a natural inhibitor for AKT1, GSK3B, CASP3, TNF and CCND1. COP represses PI3K/AKT pathway to suppress the progression of bladder cancer.

Lei Zhu,Guan Zhang,Jiasai Kang,Xinru Xu,Haoshu Zhang,Yingying Pu,Yong Huang,Dewen Tong,Qian Du

Background Folium Isatidis (Da Qing Ye), a traditional Chinese medicine, exhibits broad-spectrum antiviral and immunomodulatory properties and has been widely used in treating respiratory diseases. Porcine circovirus type 2 (PCV2), a widespread swine virus, causes respiratory disease complex in piglets and leads to substantial economic losses in the global swine industry. This study aimed to evaluate the anti-PCV2 activity of Folium Isatidis . Materials and methods The anti-PCV2 activity of Folium Isatidis was first validated through both in vivo and in vitro experiments. Potential targets of Folium Isatidis were identified using TCMSP, BATMAN-TCM, and SwissTargetPrediction databases, and intersected with PCV2-related targets. Mechanism exploration involved PPI network analysis, GO annotation, and KEGG enrichment. Molecular docking analyzed component-target interactions, followed by experimental validation of the core component. Finally, the anti-PCV2 effect of the core component was verified through in vitro and in vivo experiments. Results A total of 135 overlapping targets between Folium Isatidis components and PCV2-related disease targets were identified. Key targets, including AKT1 and TNF-α, were implicated in the therapeutic effects of Folium Isatidis against PCV2. Isovitexin was identified to be the core component that directly binds to AKT1 and TNF-α, thereby inhibiting the PI3K/AKT signaling pathway and regulating TNF-α expression and activity to suppress PCV2 replication and alleviate PCV2-induced lung injury. Conclusions Our study reveals that Isovitexin, the core anti-PCV2 component of Folium Isatidis , exerts its effect by inhibiting the PI3K/AKT pathway and modulating TNF-α, thereby outlining a novel therapeutic strategy for combating PCV2 infection and associated respiratory injuries.

Salidroside alleviates senile osteoporosis in SAMP8 mice by inhibiting the ferroptosis of bone marrow stromal cells via PI3K/AKT/mTOR signaling pathway

Zhun Li,Sixia Yang,Wei Liu,Long Ling,Hailan Hu,Yanming Cao,Shouyu Xiang

Salidroside, one of the main active compounds extracted from Rhodiola, has shown promising potential for the treatment of osteoporosis. Our previous study demonstrated that salidroside alleviated cognitive dysfunction in senescence-accelerated mouse prone 8(SAMP8) mice. In this study, we further investigated the effect of salidroside on osteoporosis in SAMP8 mice and explored the mechanism. The results of micro-computed tomography(micro-CT) and histology showed that salidroside significantly increased trabecular bone formation and improved bone microstructure in senile osteoporotic SAMP8 mice, and upregulated the protein expression levels of phosphatidylinositol-3-kinase(PI3K), glutathione peroxidase 4(GPX4), and Runt-related transcription factor 2(RUNX2) in the distal femur. Cell-based assays, including the Cell Counting Kit-8(CCK-8) assay, senescence-associated β-galactosidase (SA-β-galactosidase) staining, alkaline phosphatase (ALP) staining, Alizarin Red staining, and lipid peroxide detection, demonstrated that salidroside significantly promoted the proliferation and osteogenic differentiation of senile osteoporotic bone marrow stromal cells (BMSCs) and decreased lipid peroxide levels. Furthermore, real-time polymerase chain reaction (RT-PCR) and Western blotting analysis showed that salidroside increased protein and gene expression levels of solute carrier family 7 member 11(SLC7A11), GPX4, and ferroptosis suppressor protein 1(FSP1). Additionally, salidroside also increased the phosphorylation of PI3K, AKT, and mTOR, an effect reversed by LY294002.In conclusion, our investigation showed that salidroside could prevent ferroptosis, promote proliferation, and enhance osteogenic differentiation in senile osteoporotic BMSCs, thereby alleviating senile osteoporosis in SAMP8 mice. The PI3K/AKT/mTOR signaling pathway might play a crucial role in this mechanism. These findings suggest that salidroside has the potential to prevent senile osteoporosis and may serve as a candidate for therapeutic development.

Microbiome Modulation with Lactobacillus rhamnosus GG Potentiates Curcumin's Efficacy in Reversing Gemcitabine Resistance of Gallbladder Cancer through Gut Microbiota-PI3K/AKT Axis

Yanliang Li,Siqiang Niu,Haipeng Wang,Jianhua Li

Gemcitabine (GEM) resistance remains a major challenge in the treatment of gallbladder cancer (GBC). This study investigated the synergistic effect of curcumin (CUR) combined with the probiotic Lactobacillus rhamnosus GG (LGG) in reversing chemoresistance through modulation of the gut microbiota. In GEM-resistant GBC-SD cells, the CUR–LGG combination significantly inhibited cell proliferation, suppressed migration and invasion, and induced apoptosis, as demonstrated by CCK-8, wound healing, Transwell, and flow cytometry assays. Western blot analysis revealed corresponding regulation of proliferation markers (Ki67, PCNA), apoptosis-related proteins (Bcl-2, Bax, cleaved Caspase-3), and epithelial–mesenchymal transition markers. In xenograft models, the combined treatment markedly suppressed tumor growth and altered gut microbial composition, increasing beneficial bacteria ( Lactobacillus , Bifidobacterium ) while reducing pathogenic taxa. LC–MS analysis further demonstrated restoration of bile acid homeostasis, characterized by elevated primary bile acids (GCA, CDCA) and decreased secondary bile acids (DCA, LCA). Mechanistically, the intervention significantly inhibited PI3K/AKT signaling, as confirmed by Western blot and immunohistochemistry. Bioinformatic analysis further identified PI3K/AKT as a central regulatory pathway. These findings indicate that probiotic-assisted CUR therapy reverses GEM resistance by remodeling the gut microbiota and its metabolic outputs, thereby suppressing oncogenic signaling pathways. This strategy provides a promising microbiota-based approach for improving therapeutic outcomes in GBC.

Targeting SLC7A11 to Suppress PI3K/AKT Signaling: Dapagliflozin ameliorates MASH and associated renal injury via ferroptosis inhibition and Liver-Kidney axis regulation

Huimin Qiu,Xinqi Tan,Quan Sheng,Na Yang,Chunming Jiang,Lulu Wang

Metabolic dysfunction-associated steatohepatitis (MASH) frequently induces renal injury, forming a “liver-kidney axis” vicious cycle. Current therapies primarily target hepatic lesions, failing to interrupt the cross-organ injury cascade, creating an urgent need for novel strategies. To explore dapagliflozin’s therapeutic efficacy and core mechanism in MASH and associated renal injury, we utilized in vitro models (free fatty acid [FFA]-induced HepG2 hepatocyte MASH model, HK2 renal tubular epithelial cell injury model, Transwell co-culture system) and an in vivo MASH mouse model induced by a choline-deficient, L-amino acid-defined, high-fat diet (CDAHFD). Results showed dapagliflozin dose-dependently improved dysregulated lipid metabolism, suppressed inflammation, and alleviated fibrosis in vitro and in mouse liver/kidney tissues, while upregulating SIRT1/PPARα and downregulating SREBP-1c to restore lipid homeostasis. Molecularly, dapagliflozin specifically bound to ferroptosis key regulator solute carrier family 7 member 11 (SLC7A11), upregulated its abnormally reduced expression, and inhibited PI3K/AKT pathway hyperactivation—an effect mediated via a “liver-kidney axis” paracrine mechanism with β-hydroxybutyrate (β-HB) as the key mediator. Additionally, SLC7A11 knockdown in cells conversely confirmed that the lipid-lowering effect of dapagliflozin is mediated by SLC7A11.Collectively, dapagliflozin forms hydrogen bonds with SLC7A11, modulates the SIRT1/PPARα/SREBP-1c axis, and inhibits PI3K/AKT, thereby exerting therapeutic effects on MASH and associated renal injury.

Hypoglycemic mechanism of Tegillarca granosa polysaccharides on type 2 diabetic mice by altering gut microbiota and regulating the PI3K-akt signaling pathway

Qihong Jiang,Lin Chen,Rui Wang,Yin Chen,Shanggui Deng,Guoxin Shen,Shulai Liu,Xingwei Xiang

Type 2 diabetes mellitus (T2DM) is a complex metabolic disease threatening human health. We investigated the effects of Tegillarca granosa polysaccharide (TGP) and determined its potential mechanisms in a mouse model of T2DM established through a high-fat diet and streptozotocin. TGP (5.1 × 10 3 Da) was composed of mannose, glucosamine, rhamnose, glucuronic acid, galactosamine, glucose, galactose, xylose, and fucose. It could significantly alleviate weight loss, reduce fasting blood glucose levels, reverse dyslipidemia, reduce liver damage from oxidative stress, and improve insulin sensitivity. RT-PCR and Western blotting indicated that TGP could activate the phosphatidylinositol-3-kinase/protein kinase B signaling pathway to regulate disorders in glucolipid metabolism and improve insulin resistance. TGP increased the abundance of Allobaculum , Akkermansia , and Bifidobacterium , restored the microbiota abundance in the intestinal tracts of mice with T2DM, and promoted short-chain fatty acid production. This study provides new insights into the antidiabetic effects of TGP and highlights its potential as a natural hypoglycemic nutraceutical.
