Bisphenol A (BPA) is a non-steroidal endocrine-disrupting chemical compound with applications in the production of epoxy resins and polycarbonates. Accumulating evidence suggests that BPA damages various organs and tissues, including those of the reproductive, immune, and neuroendocrine systems. However, the mechanisms by which BPA affects the intestinal tract have not been fully elucidated. We explored the adverse effects of BPA on human colonic epithelial cells in vitro by performing comprehensive viability, proliferation, invasion, and migration assays on HCT 116 and HCT-8 cells. BPA suppressed the proliferation of both cell types by regulating cell cycle progression and modulating the mitogen-activated protein kinase and phosphatidylinositol 3-kinase/protein kinase B pathways. Furthermore, BPA treatment significantly reduced the induction of matrix metalloproteinases-2 and -9 by inhibiting the binding activity of specificity protein-1, nuclear factor kappa B, and activator protein-1, thereby interfering with cell migration and invasion. This BPA-induced regulation of colonic epithelial cell proliferation, migration, invasion, and MAPK/AKT pathway was reversed by silencing p21WAF1 with siRNA. Collectively, our data indicate that BPA inhibits the proliferation and mobility of human colonic epithelial cells via p21WAF1 induction. This study provides valuable information into the precise mechanisms underlying the adverse effects of BPA on colonic epithelial cells.

Background and aimBenign prostatic hyperplasia (BPH) involves androgen-driven proliferation with reduced apoptosis. Current 5α-reductase inhibitors can cause adverse effects, motivating safer options. We evaluated whether nobiletin, a polymethoxyflavonoid, mitigates BPH features.MethodologyIn vitro, nobiletin was applied to BPH-1 epithelial and WPMY-1 stromal cells to assess anti-proliferative effects. In vivo efficacy was tested in a testosterone-induced BPH rat model administered oral nobiletin (1 or 5 mg/kg).ResultsNobiletin induced G0/G1 phase cell cycle arrest by suppressing cyclin D1, cyclin E, and cyclin-dependent kinase 2 (CDK2), while elevating p21 and p27 expression. Expression of 5α-reductase, androgen receptor (AR), fibroblast growth factor (FGF), epidermal growth factor (EGF), and B-cell lymphoma 2 (Bcl-2) was reduced, whereas Bcl-2–associated X protein (Bax) was increased. Nobiletin modulated phosphorylation of c-Jun N-terminal kinase (JNK) and p38 and suppression of protein kinase B (AKT) phosphorylation. Nobiletin reduced nuclear factor kappa B (NF-κB) DNA-binding activity, which was dependent on JNK and p38. In vivo, nobiletin reduced prostate size, weight, and epithelial thickness, accompanied by molecular markers changing in the same direction as in vitro. Molecular docking analysis further supported the potential of nobiletin to bind 5α-reductase type 2 at the catalytic site.ConclusionThese results highlight the potential of nobiletin as a novel therapeutic option for BPH.

This study investigated the anti-inflammatory effects of a short-chain fatty acid (SCFA)-enriched fermented blueberry supernatant (BBS) and its key component, propionic acid (PropA), in both in vitro and in vivo models of colitis. High-performance liquid chromatography confirmed the presence of PropA in BBS at a concentration of 1.86 mg/mL. In LPS-stimulated RAW 264.7 macrophages, BBS significantly reduced nitric oxide, monocyte chemoattractant protein-1, and interleukin-6 production in a dose-dependent manner. Western blotting revealed that BBS suppressed the expression of inducible nitric oxide synthase, COX-2, and NF-kappa B. In a DSS-induced colitis mouse model, BBS administration significantly improved disease indicators, including body weight loss, colon shortening, and spleen enlargement. Moreover, BBS restored serum IgG and colonic IgA levels and reduced systemic and local inflammatory mediators. These findings highlight the potential of SCFA-enriched fermented blueberry as a functional postbiotic food capable of modulating inflammatory responses through NF-kappa B and COX2 signaling pathways in colitis.

Bisphenol A (BPA), an exogenous endocrine-disrupting chemical, is widely used to produce polycarbonate plastics. The widely used BPA has been detected in human urine samples, raising public anxiety about the detrimental effects of BPA on the bladder. In this study, we explored regulatory mechanisms for the adverse effects of BPA in human bladder BdFC and T24 cells. BPA induced extrinsic and intrinsic apoptosis and G2/M cell cycle arrest caused by the ATM-CHK1/CHK2-CDC25c-CDC2 signaling, which ultimately inhibited the growth of human bladder cells. We also found that BPA decreased the binding activity of AP-1 and NF-kappa B transcription factors in human bladder cells, which inhibited migration and invasion through matrix metallopeptidase-2 and -9 inactivation. Phosphorylation of MAPKs was implicated with BPA-mediated detrimental effects in human bladder cells. Collectively, our results provide a novel explanation for the underlying molecular mechanisms that BPA induces cytotoxicity in human bladder cells.

BACKGROUND/OBJECTIVES:Rosa hybrida has been demonstrated to exert biological effects on several cell types. This study investigated the efficacy of the edible ethanol extract of R. hybrida (EERH) against human colorectal carcinoma cell line (HCT116) cells. MATERIALS/METHODS:HCT116 cells were cultured with different concentrations of EERH (0, 400, 600, 800, and 1,000 µg/mL) in Dulbecco's modified Eagle medium. Cell viability was measured using the 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide and viable cell counting assays. Cell cycle pattern was observed by flow cytometry analysis. The wound-healing migration assay, invasion assay, and zymography were used to determine the migratory and invasive level of HCT116 cells treated with EERH. The protein expression and binding ability level of HCT116 cells following EERH treatment were analyzed via immunoblotting and the electrophoretic mobility shift assay. RESULTS:EERH suppressed HCT116 cell proliferation, thus arresting the G1-phase cell cycle. It also reduced cyclin-dependent kinases and cyclins, which are associated with p27KIP1 expression. Additionally, EERH differentially regulated the phosphorylation of extracellular signal-regulated kinase 1/2, c-Jun NH2-terminal kinase, p38, and protein kinase B. Moreover, EERH treatment inhibited the enzymatic activity of matrix metalloproteinase-9 (MMP-9) and MMP-2, resulting in HCT116 cell migration and invasion. The EERH-induced inhibition of MMP-9 and MMP-2 was attributed to the reduced transcriptional binding of activator protein-1, specificity protein-1, and nuclear factor-κB motifs in HCT116 cells. Kaempferol was identified as the main compound contributing to EERH's antitumor activity. CONCLUSION:EERH inhibits HCT116 cell proliferation and metastatic potential. Therefore, it is potentially useful as a preventive and curative nutraceutical agent against colorectal cancer.

Introduction Angiogenesis plays a significant role in the development of tumor progression and inflammatory diseases. The role of IL-28A in angiogenesis and its precise regulatory mechanisms remain rarely elucidated. Objectives We report the novel regulatory role of IL-28A in physiological angiogenesis. The study aimed to elucidate the regulatory mechanisms involved in IL-28A-mediated angiogenesis and identify key genes associated with IL-28A-induced angiogenic responses. Methods To know the effect of IL-28A on angiogenesis, HUVECs were applied to perform proliferation, migration, invasion, tube formation, immunoblot, and EMSA. Gene expression changes in HUVECs following IL-28A treatment were analyzed by NGS. The functional role of HSP70-1 and IL-10Rβ in IL-28A-induced angiogenic responses was evaluated using PCR and siRNA knockdown. Animal studies were conducted by aortic ring ex vivo assays, Matrigel plug in vivo assays, and immunochemistry using HSP70-1 knockout and transgenic mice models. The efficacy of IL-28A in angiogenesis was confirmed in a hind-limb ischemia model. Results Autocrine/paracrine actions in HUVECs regulated IL-28A protein expression. Exogenous IL-28A increased the proliferation of HUVECs via eNOS/AKT and ERK1/2 signaling. IL-28A treatment promoted migration, invasion, and capillary tube formation of HUVECs through induction of the AP-1/NF-κB/MMP-2 network, which was associated with eNOS/AKT and ERK1/2 signaling. The efficacy of IL-28A-induced angiogenic potential was confirmed by aortic ring and Matrigel plug assay. HSP70-1 was identified as an IL-28A-mediated angiogenic effector gene using bioinformatics. Knockdown of HSP70-1 abolished angiogenic responses and eNOS/AKT signaling in IL-28A-treated HUVECs. IL-28A-induced microvessel sprouting formation was testified in HSP70-1-deficient and HSP70-1 transgenic mice. Flow recovery in hind-limb ischemia mice was accelerated by IL-28A injection. Finally, ablation of the IL-10Rβ gene impeded the angiogenic responses and eNOS/AKT signaling stimulated by IL-28A in HUVECs. Conclusion HSP70-1 drives the progression of angiogenesis by the IL-28A/IL-10Rβ axis via eNOS/AKT signaling and the AP-1/NF-κB/MMP-2 network.

Bisphenol A (BPA) is commonly used to produce epoxy resins and polycarbonate plastics. BPA is an endocrine-disrupting chemical that is leaked from the polymer and absorbed into the body to disrupt the endocrine system. Although BPA may cause cytotoxicity in the prostate, a hormone-dependent reproductive organ, its underlying mechanism has not yet been elucidated. Here, we investigated the effects of BPA on cell proliferation, apoptosis, and the wound healing process using prostate epithelial cells (RWPE-1) and stromal cells (WPMY-1). Observations revealed that BPA induced G2/M cell cycle arrest in both cell types through the ATM-CHK1/CHK2-CDC25c-CDC2 signaling pathway, and the IC50 values were estimated to be 150 μM. Furthermore, BPA was found to induce caspase-dependent apoptosis through initiator (caspase-8 and -9) and executioner (caspase-3 and -7) caspase cascades. In addition, BPA interfered with the wound healing process through inhibition of MMP-2 and - 9 expression, accompanied by reductions in the binding activities of AP-1 as well as NF-κB motifs. Phosphorylation of MAPKs was associated with the BPA-mediated toxicity of prostate cells. These results suggest that BPA exhibits prostate toxicity by inhibiting cell proliferation, inducing apoptosis, and interfering with the wound healing process. Our study provided new insights into the precise molecular mechanisms of BPA-induced toxicity in human prostate cells.

Resveratrol can inhibit cell proliferation and metastasis and induce apoptosis. However, the mechanisms of action through which resveratrol inhibits the abnormal proliferation of prostate stromal cells, causing prostatic hyperplasia, have not been fully elucidated. Here, we evaluated the inhibitory effects of resveratrol on cell proliferation associated with prostatic hyperplasia using WPMY-1 cells. Our results showed that resveratrol inhibited the proliferation of WPMY-1 cells via the induction of G0/G1-phase cell cycle arrest, which was caused by downregulated expression of cyclins and cyclin-dependent kinases regulated by increased p21WAF1 and p27KIP1 expression level. In addition, resveratrol treatment suppressed the phosphorylation of phosphatidylinositol 3-kinase/AKT and extracellular signal-regulated kinase 1/2. The expression levels of molecular markers affecting prostate development were also reduced by treatment with resveratrol. Finally, resveratrol attenuated the binding activity of the transcription factor nuclear factor-κB in WPMY-1 cells, and accelerated apoptotic cell death via intrinsic cascade pathway. These results indicate that resveratrol may be useful for the prevention or treatment of prostatic hyperplasia.

Here, we explored the anti-tumor efficacy of a cyclic pentadepsipeptide, N-methylsansalvamide (MSSV), in bladder cancer. MSSV inhibited the proliferation of both bladder cancer 5637 and T24 cells, which was attributed to the G1-phase cell cycle arrest, apoptosis induction, and alteration of mitogen-activated protein kinases (MAPKs) and protein kinase b (AKT) signaling pathways. Additionally, the treatment of bladder cancer cells with MSSV suppressed migratory and invasive potential via the transcription factor-mediated expression of matrix metalloproteinase 9 (MMP-9). MSSV abrogated vascular endothelial growth factor (VEGF)-induced angiogenic responses in vitro and in vivo. Furthermore, our result showed the potent anti-tumor efficacy of MSSV in a xenograft mouse model implanted with bladder cancer 5637 cells. Finally, acute toxicity test data obtained from blood biochemical test and liver staining indicated that the oral administration of MSSV at 2000 mg/kg caused no adverse cytotoxic effects. Our preclinical data described the potent anti-angiogenic and anti-tumor efficacy of MSSV and showed no signs of acute toxicity, thereby suggesting the putative potential of oral MSSV as a novel anti-tumor agent in bladder cancer treatment.

Various physiological benefits have been linked to Hizikia fusiforme (HF), an edible brown seaweed. Here, fucose-containing sulfated polysaccharides were extracted from celluclast-processed HF (SPHF) and their antitumor efficacy against bladder cancer was evaluated in vitro and in vivo. SPHF possesses high sulfated polysaccharide and fucose contents and free radical scavenging activities compared to those of celluclast-processed HF extracts (CHF). SPHF inhibited bladder cancer EJ cell proliferation via G1-phase cell cycle arrest. This was due to the induction of p21WAF1 expression associated with the downregulation of CDKs and cyclins. Moreover, JNK phosphorylation was identified as an SPHF-mediated signaling molecule. SPHF treatment also hindered the migration and invasion of EJ cells by inhibiting MMP-9 expression, which was attributed to the repression of transcriptional binding to NF-κB, AP-1, and Sp-1 in the MMP-9 promoter region. In an animal study, SPHF treatment suppressed EJ tumor growth in xenograft mice similarly to cisplatin. Furthermore, no toxicity signs were found after weight loss assessment, biochemical tests, and organ tissue immunostaining during oral administration of 20–200 mg/kg SPHF for 20 days. Therefore, our study demonstrates the antitumor efficacy of SPHF in vitro and in vivo, thus highlighting its potential for bladder cancer treatment development.

Purpose: In this study, we tested whether the resveratrol-enriched peanut sprout extracts cultivated with fermented sawdust medium (PSEFS) could suppress benign prostatic hyperplasia (BPH) in vitro and in vivo. Materials and Methods: The mode of action of PSEFS was estimated by employing high-performance liquid chromatography analysis, MTT assay, cell counting, cell cycle analysis, immunoblots, and immunoprecipitation and electrophoretic mobility shift assay. In vivo efficacy of PSEFS was analyzed in BPH animal model via immunostaining and enzyme-linked immunosorbent assay. Results: We selected the Yesan peanut sprout variety, which contains the highest level of resveratrol. The resveratrol levels in PSEFS were higher than those obtained with hydroponic technology. PSEFS treatment induced cell cycle arrest at the G1- phase by downregulating CDK4 and cyclin D1 via p21WAF1 induction in the RWPE-1 and WPMY prostate cells, thereby decreasing their proliferation. Treatment with PSEFS decreased ERK1/2 phosphorylation and increased JNK phosphorylation. The levels of DNA-bound transcription factors associated with proliferation (nuclear factor-κB, Sp-1, and AP-1) decreased upon PSEFS treatment in both prostate cells. Additionally, the levels of the molecular markers of BPH development (5α-reductase, androgen receptor, fibroblast growth factor, Bcl-2, and Bax) also changed by the addition of PSEFS. Finally, in a testosterone propionate-induced BPH model in rats, PSEFS administration attenuated the size, weight, and thickness of prostate tissues with no signs of death. Conclusions: These results showed that PSEFS inhibited BPH both in vitro and in vivo and might be useful in the development of a potential BPH therapy.

Peanut sprout extracts reportedly exhibit numerous beneficial effects; however, there are few investigations on the biological effects of peanut sprout extracts cultivated with fermented sawdust medium (PSEFS). Here, we examined whether PSEFS demonstrates antitumor activity against bladder cancer, in vitro and in vivo. The results showed that PSEFS prohibited the proliferation of bladder cancer T24 cells, with this effect attributed to induction of cell cycle arrest at the G1 phase through reduced expression of cyclins and cyclin-dependent kinases caused by a promotion of p21WAF1 expression. Additionally, PSEFS induced phosphorylation of p38 mitogen-activated protein kinase. Moreover, PSEFS treatment attenuated the invasive and migratory potential of T24 cells due to decreased matrix metalloproteinase-9 activity combined with downregulation of the transcriptional binding activity of SP1, activator protein -1, and nuclear factor-kappaB. Furthermore, PSEFS (20 mg/kg) attenuated the tumor-growth rate in xenograft mice bearing T24 cells, with an effect equivalent to that of cisplatin and in the absence of toxicity following weight-loss evaluation and hematobiochemical testing of PSEFS-treated mice. These results demonstrated the antitumor efficacy of PSEFS both in vitro and in vivo, thereby reporting it as a potential candidate for development of novel agents against bladder cancer.

Carnosine, a naturally producing dipeptide, exhibits various beneficial effects. However, the possible role of carnosine in vascular disorders associated with pathological conditions, including proliferation and migration of vascular smooth muscle cells (VSMCs), largely remains unrevealed. Here, we investigated the regulatory role and mechanism of carnosine in platelet-derived growth factor (PDGF)-induced VSMCs. Carnosine inhibited the proliferation of PDGF-induced VSMCs without any cytotoxic effects. Carnosine treatment also induced G1-phase cell cycle arrest by causing a p21WAF1-mediated reduction in the expression of both cyclin-dependent kinases (CDKs) and cyclins in PDGF-treated VSMCs. Carnosine treatment suppressed c-Jun N-terminal kinase (JNK) phosphorylation in PDGF-stimulated signaling. Additionally, carnosine significantly prevented the migration of VSMCs exposed to PDGF. Carnosine abolished matrix metalloproteinase (MMP)-9 activity via reduced transcriptional binding activity of NF-κB, Sp-1, and AP-1 motifs in PDGF-treated VSMCs. Moreover, using aortic assay ex vivo, it was observed that carnosine addition attenuated PDGF-stimulated sprout outgrowth of VSMCs. Taken together, these results demonstrated that carnosine impeded the proliferation and migration of PDGF-stimulated VSMCs by regulating cell cycle machinery, JNK signaling, and transcription factor-mediated MMP-9 activity as well as prevented ex vivo sprout outgrowth of blood vessels. Thus, carnosine may be a potential candidate for preventing vascular proliferative disease.

Nimbolide, an active chemical constituent of Azadirachta indica , reportedly has several physiological effects. Here, we assessed novel anticancer effects of nimbolide against bladder cancer EJ and 5637 cells. Nimbolide treatment inhibited the proliferation of both bladder cancer cell lines with an IC 50 value of 3 μ M. Treatment of cells with nimbolide induced G2/M phase cell cycle arrest via both Chk2-Cdc25C-Cdc2/cyclin B1-Wee1 pathway and Chk2-p21WAF1-Cdc2/cyclin B1-Wee1 pathway. Nimbolide increased JNK phosphorylation and decreased p38MAPK and AKT phosphorylation. Additionally, nimbolide impeded both wound healing migration and invasion abilities by suppressing matrix metalloproteinase-9 (MMP-9) activity. Finally, nimbolide repressed the binding activity of NF- κ B, Sp-1, and AP-1 motifs, which are key transcription factors for MMP-9 activity regulation. Overall, our study indicates that nimbolide is a potential chemotherapeutic agent for bladder cancer.

Carnosine, a naturally occurring dipeptide, was recently reported to exhibit anticancer activity; however, the molecular mechanisms and regulators underlying its activity against tumor-associated angiogenesis remain unidentified. In this study, we evaluated the in vitro and in vivo antitumor effects of carnosine in EJ bladder cancer cells and EJ-xenografted BALB/c nude mice, respectively. In addition, in vitro capillary tube formation of HUVECs, ex vivo aortic ring and in vivo Matrigel plug assays were employed to examine the antiangiogenic potential of carnosine. Carnosine significantly inhibited EJ cell proliferation. Flow cytometric and immunoblot analyses indicated that carnosine modulated regulators of the G1 cell cycle phase, including cyclin D1, CDK4 and p21WAF1. The mitogen-activated protein kinases, ERK and p38, but not JNK or AKT, responded to carnosine. Carnosine inhibited the migratory and invasive potential of EJ cells by inhibiting MMP-9 activity, which was associated with suppression of binding activity of NF-κB, SP-1 and AP-1. In xenograft tumors, carnosine exhibited antitumor activity equivalent to cisplatin, but no weight loss occurred in carnosine-treated mice. In HUVECs, carnosine inhibited VEGF-mediated proliferation, colony tube formation, migration and invasion. The antiangiogenic activity of carnosine was partially due to the suppression of VEGFR-2-mediated ERK/AKT/eNOS signaling and MMP-2. Furthermore, using aortic ring and Matrigel plug assays, we confirmed the antiangiogenic activity of carnosine. Given that targeting tumor-associated angiogenesis is a proven effective therapeutic strategy, our results may provide valuable information for the development of preventive or therapeutic agents for bladder cancer patients.

Background: Diallyl trisulfide (DATS), a bioactive sulfur compound in garlic, has been highlighted due to its strong anti-carcinogenic activity. Objective: The current study investigated the molecular mechanism of garlic-derived DATS in cancer cells. Additionally, we explored possible molecular markers to monitoring clinical responses to DATS-based chemotherapy. Design: EJ bladder carcinoma cells were treated with different concentration of DATS. Molecular changes including differentially expressed genes in EJ cells were examined using immunoblot, FACS cell cycle analysis, migration and invasion assays, electrophoresis mobility shift assay (EMSA), microarray, and bioinformatics analysis. Results: DATS inhibited EJ cell growth via G2/M-phase cell cycle arrest. ATM-CHK2-Cdc25c-p21WAF1-Cdc2 signaling cascade, MAPKs, and AKT were associated with the DATS-mediated growth inhibition of EJ cells. DATS-induced inhibition of migration and invasion was correlated with down-regulated MMP-9 via reduced activation of AP-1, Sp-1, and NF-κB. Through microarray gene expression analysis, ANGPTL4, PLCXD1, and MMP3 were identified as candidates of molecular targets of DATS. Introduction of each gene to EJ cells revealed that ANGPTL4 was associated with the DATS-induced inhibition of cell growth, migration, and invasion. Conclusions: ANGPTL4 regulates DATS-mediated inhibition of proliferation, migration, and invasion of EJ cells, and thus, has potential as a prognostic marker for bladder cancer patients.

Although recent studies have demonstrated the anti-tumor effects of garlic extract (GE), the exact molecular mechanism is still unclear. In this study, we investigated the molecular mechanism associated with the inhibitory action of GE against bladder cancer EJ cell responses. Treatment with GE significantly inhibited proliferation of EJ cells dose-dependently through G2/M-phase cell cycle arrest. This G2/M-phase cell cycle arrest by GE was due to the activation of ATM and CHK2, which appears to inhibit phosphorylation of Cdc25C (Ser216) and Cdc2 (Thr14/Tyr15), this in turn was accompanied by down-regulation of cyclin B1 and up-regulation of p21WAF1. Furthermore, GE treatment was also found to induce phosphorylation of MAPK (ERK1/2, p38MAPK, and JNK) and AKT. In addition, GE impeded the migration and invasion of EJ cells via inhibition of MMP-9 expression followed by decreased binding activities of AP-1, Sp-1, and NF-κB motifs. Based on microarray datasets, we selected Heat shock protein A6 (HSPA6) as the most up-regulated gene responsible for the inhibitory effects of GE. Interestingly, overexpression of HSPA6 gene resulted in an augmentation effect with GE inhibiting proliferation, migration, and invasion of EJ cells. The augmentation effect of HSPA6 was verified by enhancing the induction of G2/M-phase-mediated ATM-CHK2-Cdc25C-p21WAF1-Cdc2 cascade, phosphorylation of MAPK and AKT signaling, and suppression of transcription factor-associated MMP-9 regulation in response to GE in EJ cells. Overall, our novel results indicate that HSPA6 reinforces the GE-mediated inhibitory effects of proliferation, migration, and invasion of EJ cells and may provide a new approach for therapeutic treatment of malignancies.

Ophiopogon japonicus is known to have various pharmacological effects. The present study investigated the effects of an extract of fermented Ophiopogon japonicas (FEOJ) on thrombin‑treated vascular smooth muscle cells (VSMCs). FEOJ treatment inhibited the proliferation of VSMCs treated with thrombin as indicated by an MTT assay. These inhibitory effects were associated with decreased phosphorylation of AKT, reduced expression of cyclin D1 and increased expression of p27KIP1 in thrombin‑induced VSMCs. In addition, FEOJ treatment suppressed the thrombin‑stimulated migration of VSMCs as demonstrated by a wound‑healing migration assay. Furthermore, zymographic analyses demonstrated that treatment of FEOJ with VSMCs suppressed the thrombin‑induced expression of matrix metalloproteinase (MMP)‑2, which was attributed to the reduction of nuclear factor (NF)‑κB binding activity. Collectively, these results demonstrated that FEOJ induced p27KIP1 expression, reduced cyclin D1 expression and AKT phosphorylation, and inhibited MMP‑2 expression mediated by downregulation of NF‑κB binding activity in thrombin‑treated VSMCs, which led to growth inhibition and repression of migration. These results supported the use of FEOJ for the prevention of vascular diseases and provided novel insight into the underlying mechanism of action.
