Abstract
Breast cancer is the most common invasive neoplasm and the leading cause of cancer death in women worldwide. The main cause of mortality in cancer patients is invasion and metastasis, where the epithelial-mesenchymal transition (EMT) is a crucial player in these processes. Pharmacological therapy has plants as its primary source, including isoflavonoids. Brazilin is an isoflavonoid isolated from Haematoxilum brasiletto that has shown antiproliferative activity in several cancer cell lines. In this study, we evaluated the effect of Brazilin on canonical markers of EMT such as E-cadherin, vimentin, Twist, and matrix metalloproteases (MMPs). By Western blot, we evaluated E-cadherin, vimentin, and Twist expression and the subcellular localization by immunofluorescence. Using gelatin zymography, we determined the levels of secretion of MMPs. We used Transwell chambers coated with matrigel to determine the in vitro invasion of breast cancer cells treated with Brazilin. Interestingly, our results show that Brazilin increases 50% in E-cadherin expression and decreases 50% in vimentin and Twist expression, MMPs, and cell invasion in triple-negative breast cancer (TNBC) MDA-MB-231 and to a lesser extend in MCF7 ER+ breast cancer cells. Together, these findings position Brazilin as a new molecule with great potential for use as complementary or alternative treatment in breast cancer therapy in the future.

Abstract
Vascular smooth muscle cells (VSMCs) proliferation is a critical event that contributes to the pathogenesis of vascular remodeling such as hypertension, restenosis, and pulmonary hypertension. Increasing evidences have revealed that VSMCs proliferation is associated with the activation of receptor tyrosine kinases (RTKs) by their ligands, including the insulin-like growth factor receptor (IGFR), fibroblast growth factor receptor (FGFR), epidermal growth factor receptor (EGFR), vascular endothelial growth factor receptor (VEGFR), and platelet-derived growth factor receptor (PDGFR). Moreover, some receptor tyrosinase inhibitors (TKIs) have been found and can prevent VSMCs proliferation to attenuate vascular remodeling. Therefore, this review will describe recent research progress on the role of RTKs and their inhibitors in controlling VSMCs proliferation, which helps to better understand the function of VSMCs proliferation in cardiovascular events and is beneficial for the prevention and treatment of vascular disease.

Abstract
Cardiovascular diseases are the leading cause of death worldwide. The long-term aim of cardiovascular disease therapy is to reduce the mortality rate and decelerate the progression of cardiovascular organ damage. Current therapies focus on recovering heart function and reducing risk factors such as hyperglycemia and dyslipidemia. However, oxidative stress and inflammation are important causes of further damage to cardiovascular organs. Caesalpinia sappan Linn. (Fabaceae), a flowering tree native to tropical Asia, has antioxidant and anti-inflammatory properties. It is used as a natural dye to color food and beverages and as a traditional treatment for diarrhea, diabetes, and blood stasis. The phytochemical compounds in C. sappan, mainly the homoisoflavonoids brazilin, sappanone A, protosappanin, and hematoxylin, can potentially be used to protect cardiovascular organs. This review aims to provide updates on recent developments in research on C. sappan in relation to treatment of cardiovascular diseases. Many studies have reported protective effects of the plant’s bioactive compounds that reduce cardiac damage and enhance vasorelaxation. For example, brazilin and sappanone A have an impact on molecular and cellular changes in cardiovascular disease pathogenesis, mainly by modulating oxidative, inflammatory, and apoptotic signaling pathways. Therefore, bioactive compounds of C. sappan have the potential to be developed as therapeutic agents to combat cardiovascular diseases like myocardial infarction and vascular disease. This review could help further the understanding of the possible modulatory role of the compounds in cardiovascular diseases, thereby facilitating future studies.

Abstract
Cancer is a public health problem worldwide, and one of the crucial steps within tumor progression is the invasion and metastasis of cancer cells, which are directly related to cancer-associated deaths in patients. Recognizing the molecular markers involved in invasion and metastasis is essential to find targeted therapies in cancer. Interestingly, about 50% of the discovered drugs used in chemotherapy have been obtained from natural sources such as plants, including isoflavonoids. Until now, most drugs are used in chemotherapy targeting proliferation and apoptosis-related molecules. Here, we review recent studies about the effect of isoflavonoids on molecular targets and signaling pathways related to invasion and metastasis in cancer cell cultures, in vivo assays, and clinical trials. This review also reports that glycitein, daidzein, and genistein are the isoflavonoids most studied in preclinical and clinical trials and displayed the most anticancer activity targeting invasion-related proteins such as MMP-2 and MMP-9 and also EMT-associated proteins. Therefore, the diversity of isoflavonoids is promising molecules to be used as chemotherapeutic in invasive cancer. In the future, more clinical trials are needed to validate the effectiveness of the various natural isoflavonoids in the treatment of invasive cancer.

7- O-methylpunctatin, a Novel Homoisoflavonoid, Inhibits Phenotypic Switch of Human Arteriolar Smooth Muscle Cells. Biomolecules 2019; 9:biom9110716.

Abstract
Remodeling of arterioles is a pivotal event in the manifestation of many inflammation-based cardio-vasculopathologies, such as hypertension. During these remodeling events, vascular smooth muscle cells (VSMCs) switch from a contractile to a synthetic phenotype. The latter is characterized by increased proliferation, migration, and invasion. Compounds with anti-inflammatory actions have been successful in attenuating this phenotypic switch. While the vast majority of studies investigating phenotypic modulation were undertaken in VSMCs isolated from large vessels, little is known about the effect of such compounds on phenotypic switch in VSMCs of microvessels (microVSMCs). We have recently characterized a novel homoisoflavonoid that we called 7-O-methylpunctatin (MP). In this study, we show that MP decreased FBS-induced cell proliferation, migration, invasion, and adhesion. MP also attenuated adhesion of THP-1 monocytes to microVSMCs, abolished FBS-induced expression of MMP-2, MMP-9, and NF-κB, as well as reduced activation of ERK1/2 and FAK. Furthermore, MP-treated VSMCs showed an increase in early (myocardin, SM-22α, SM-α) and mid-term (calponin and caldesmon) differentiation markers and a decrease in osteopontin, a protein highly expressed in synthetic VSMCs. MP also reduced transcription of cyclin D1, CDK4 but increased protein levels of p21 and p27. Taken together, these results corroborate an anti-inflammatory action of MP on human microVSMCs. Therefore, by inhibiting the synthetic phenotype of microVSMCs, MP may be a promising modulator for inflammation-induced arteriolar pathophysiology.

Abstract
Many natural products have been so far tested regarding their potency to inhibit vascular smooth muscle cell proliferation, a process involved in atherosclerosis, pulmonary hypertension and restenosis. Compounds studied in vitro and in vivo as VSMC proliferation inhibitors include, for example indirubin-3'-monoxime, resveratrol, hyperoside, plumericin, pelargonidin, zerumbone and apamin. Moreover, taxol and rapamycin, the most prominent compounds applied in drug-eluting stents to counteract restenosis, are natural products. Numerous studies show that natural products have proven to yield effective inhibitors of vascular smooth muscle cell proliferation and ongoing research effort might result in the discovery of further clinically relevant compounds.

Abstract
The endothelial-to-mesenchymal transition (EndMT) has been demonstrated to be involved in pulmonary vascular remodeling. It is partly attributed to oxidative and inflammatory stresses in endothelial cells. In current study, we conducted a series of experiments to clarify the effect of salvianolic acid A (SAA), a kind of polyphenol compound, in the process of EndMT in human pulmonary arterial endothelial cells and in vivo therapeutic efficacy on vascular remodeling in monocrotaline (MCT)-induced EndMT. EndMT was induced by TGFβ1 in human pulmonary arterial endothelial cells (HPAECs). SAA significantly attenuated EndMT, simultaneously inhibited cell migration and reactive oxygen species (ROS) formation. In MCT-induced pulmonary arterial hypertension (PAH) model, SAA improved vascular function, decreased TGFβ1 level and inhibited inflammation. Mechanistically, SAA stimulated Nrf2 translocation and subsequent heme oxygenase-1 (HO-1) up-regulation. The effect of SAA on EndMT in vitro was abolished by ZnPP, a HO-1 inhibitor. In conclusion, this study indicates a deleterious impact of oxidative stress on EndMT. Polyphenol antioxidant treatment may provide an adjunctive action to alleviate pulmonary vascular remodeling via inhibiting EndMT.

Abstract
Vascular smooth muscle cells (VSMCs) have an important role in atherosclerosis development. Evidence has demonstrated that adipose differentiation-related protein (ADRP) is associated with foam cell formation and atherosclerosis progression. However, to the best of our knowledge, no previous studies have investigated the role of ADRP knockdown in platelet-derived growth factor (PDGF)-stimulated proliferation and migration of VSMCs in vitro. Furthermore, the effect of ADRP knockdown on neointima formation in vivo remains unclear. In the present study, primary human aortic VSMCs were incubated with PDGF following ADRP small interfering (si)RNA transfection. Cell viability, migration and cell cycle distribution were analyzed by MTT, wound healing and Transwell assays and flow cytometry, respectively. Extracellular signal-regulated kinase (ERK), phosphorylated (p)-ERK, Akt, p-Akt, proliferating cell nuclear antigen (PCNA), matrix metalloproteinase (MMP)-2 and MMP-9 protein levels were determined by western blotting. Apolipoprotein E−/− mice fed an atherogenic diet were injected with siADRP or control siRNA twice a week. After 3 weeks of therapy, aortas were excised and ADRP mRNA and protein expression was determined. Neointima formation was assessed by hematoxylin and eosin staining. The results of the current study demonstrated that ADRP knockdown significantly inhibited PDGF-induced increases in VSMC viability, caused G1 phase cell cycle arrest and decreased PCNA expression. Knockdown of ADRP inhibited PDGF-induced migration of VSMCs by reducing MMP protein expression and activity. In addition, the present study also demonstrated that ADRP knockdown inhibited ERK and Akt signaling pathways in response to PDGF. Furthermore, siADRP administration suppressed neointima formation in the mouse model. The results of the present study indicate that ADRP may be a potential target for the treatment of atherosclerosis.

Abstract
This study contributes to the continual discovery of lifespan-extending compounds from plants, using the Caenorhabditis elegans model system. An ethyl acetate soluble fraction of methanol extract from the heartwood of Caesalpinia sappan showed a significant lifespan-extending activity. Subsequent activity-guided chromatography of the ethyl acetate-soluble fraction led to the isolation of brazilin. Brazilin showed potent 2,2-diphenyl-1-picrylhydrazyl radical scavenging and superoxide anion quenching activities and also revealed a lifespan-extending activity in C. elegans under normal culture conditions. Brazilin also exhibited the protective effects against thermal, oxidative and osmotic stress conditions to improve the survival rate of the nematode. Furthermore, brazilin elevated superoxide dismutase (SOD) activity and decreased intracellular reactive oxygen species accumulation in C. elegans. Further studies showed that brazilin-mediated increased stress tolerance of worms could be due to increased expressions of stress resistance proteins such as heat shock protein (HSP-16.2) and superoxide dismutase (SOD-3). Besides, there were no significant, brazilin-induced changes in aging-related factors, including progeny production, food intake, and growth, indicating brazilin influences longevity activity independent of affecting these factors. Brazilin increased the body movement of aged worms, indicating brazilin affects the healthspan and lifespan of nematode. These results suggest that brazilin contributes to the lifespan of C. elegans under both normal and stress conditions by increasing the expressions of stress resistance proteins.

Background Although nowadays it is well known that the human transcriptome can importantly vary according to external or environmental condition, the reflection of this concept when studying oxidative stress and its direct relationship with gene expression profiling during the process of atherogenesis has not been thoroughly achieved. Objective The ability to analyze genome-wide gene expression through transcriptomics has shown that the genome responds dynamically to diverse stimuli. Here, we describe the transcriptome of human vascular smooth muscle cells (hVSMC) stimulated by native and oxidized low-density lipoprotein (nLDL and oxLDL respectively), with the aim of assessing the early molecular changes that induce a response in this cell type resulting in a transcriptomic transformation. This expression has been demonstrated in atherosclerotic plaques in vivo and in vitro, particularly in the light of the oxidative modification hypothesis of atherosclerosis. Approach and Results Total RNA was isolated with TRIzol reagent (Life Technologies) and quality estimated using an Agilent 2100 bioanalyzer. The transcriptome of hVSMC under different experimental conditions (1,5 and 24 hours for nLDL and oxLDL) was obtained using the GeneChip Human Gene 1.0 ST (Affymetrix) designed to measure gene expression of 28,869 well-annotated genes. A fixed fold-change cut-off corresponding to ± 2 was used to identify genes exhibiting the most significant variation and statistical significance (P< 0.05), and 8 genes validated by qPCR using Taqman probes. Conclusions 10 molecular processes were significantly affected in hVSMC: Apoptosis and cell cycle, extracellular matrix remodeling, DNA repair, cholesterol efflux, cGMP biosynthesis, endocytic mechanisms, calcium homeostasis, redox balance, membrane trafficking and finally, the immune response to inflammation. The evidence we present supporting the hypothesis for the involvement of oxidative modification of several processes and metabolic pathways in atherosclerosis is strengthen by the fact that gene expression patterns obtained when hVSMC are incubated for a long period of time in the presence of nLDL, correspond very much the same as when cells are incubated for a short period of time in the presence of chemically modified oxLDL. Our results indicate that under physiological conditions and directly related to specific environmental conditions, LDL particles most probably suffer chemical modifications that initially serve as an alert signal to overcome a harmful stimulus that with time might get transformed to a pathological pattern and therefore consolidate a pathological condition.

Abstract
Aim: Atherosclerosis is a kind of chronic inflammatory disease. A crucial pathology change of atherosclerosis is the migration of activated VSMCs to the intima where they interact with leukocytes by expressing adhesion molecules, including intercellular cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1). Moreover, monocyte chemoattractant protein-1 (MCP-1) expressed by VSMCs plays an important role in recruiting monocytes and macrophages. Leech (Whitmania pigra Whitman) is a traditional Chinese medicine to treat cardiovascular diseases including atherosclerosis, however previous research has rarely reported the molecular mechanism for its curative effect. Thus, our study focuses on the effects of leech extracts on the expression of inflammatory factors, adhesion molecules and MCP-1 in rat VSMCs. Methods: In our present study, wound-healing assay and Boyden chamber model were applied to evaluate the anti-migration effect of LEE (Leech Enzyme Extracts) on LPS induced VSMCs. The anti-adhesion effect was assessed using DiI-labeled THP-1 and RAW264.7. Results: LEE suppressed LPS-induced VSMCs migration and decreased the chemotaxis and adhesive capacity of THP-1 and RAW264.7 to LPS-stimulated VSMCs. LEE also attenuated the upregulation of a variety of pro-atherosclerotic factors by inhibiting the phosphorylation of p38 MAPK. LEE was also observed to prevent NF-κB p65 nuclear localization using immune-fluorescent staining. Conclusions: In conclusion, LEE suppresses LPS-induced upregulation of inflammatory factors, adhesion molecules and MCP-1 in rat VSMCs mainly via inhibiting the p38 MAPK/NF-κB pathways, thus partly uncovered LEE's molecular mechanisms for its therapeutic effect on atherosclerosis.

Abstract
Renal ischemia-reperfusion (I/R) injury is associated with high morbidity and mortality as there is currently no available effective therapeutic strategy with which to treat this injury. Thus, the aim of this study was to investigate the potential protective effects of brazilin, a major active component of the Chinese medicine Caesalpinia sappan L., against renal I/R injury in vitro and in vivo. Rats were subjected to removal of the right kidney and I/R injury to the left kidney (ischemia for 45 min followed by reperfusion for 24 h). Treatment with brazilin (30 mg/kg, administered intravenously at 30 min prior to ischemia) led to the reversal of I/R-induced changes in serum creatinine (Scr) and blood urea nitrogen (BUN) levels, and also attenuated the histopathological damage induced by I/R. Furthermore, TUNEL assay revealed that brazilin reduced cell necrosis, and significantly decreased the expression of tumor necrosis factor (TNF)-α and interleukin (IL)-1β in renal tissue. Moreover, HK-2 cells were used in order to elucidate the mechanisms responsible for the protective effects of brazilin. The levels of phosphorylated IκBα and the nuclear translocation of nuclear factor-κB (NF-κB) were all evidently decreased by brazilin. These findings suggested that pre-treatment with brazilin protects against I/R-induced renal damage and suppresses the inflammatory response by inhibiting the activation of the NF-κB signaling pathway.

Abstract
AIM Brazilin is one of the major constituents of Caesalpinia sappan L with various biological activities. This study sought to investigate the vasorelaxant effect of brazilin on isolated rat thoracic aorta and explore the underlying mechanisms. METHODS Endothelium-intact and -denuded aortic rings were prepared from rats. The tension of the preparations was recorded isometrically with a force displacement transducer connected to a polygraph. The phosphorylation levels of ERK1/2 and myosin light chain (MLC) were analyzed using Western blotting assay. RESULTS Application of brazilin (10-100 μmol/L) dose-dependently relaxed the NE- or high K(+)-induced sustained contraction of endothelium-intact aortic rings (the EC50 was 83.51±5.6 and 79.79±4.57 μmol/L, respectively). The vasorelaxant effect of brazilin was significantly attenuated by endothelium removal or by pre-incubation with L-NAME, methylene blue or indomethacin. In addition, pre-incubation with brazilin dose-dependently attenuated the vasoconstriction induced by KCl, NE or Ang II. Pre-incubation with brazilin also markedly suppressed the high K(+)-induced extracellular Ca(2+) influx and NE-induced intracellular Ca(2+) release in endothelium-denuded aortic rings. Pre-incubation with brazilin dose-dependently inhibited the NE-stimulated phosphorylation of ERK1/2 and MLC in both endothelium-intact and -denuded aortic rings. CONCLUSION Brazilin induces relaxation in rat aortic rings via both endothelium-dependent and -independent ways as well as inhibiting NE-stimulated phosphorylation of ERK1/2 and MLC. Brazilin also attenuates vasoconstriction via blocking voltage- and receptor-operated Ca(2+) channels.

Abstract
Deer velvet antler (DVA) is one of the most popular medicines in China. Numerous studies have demonstrated that velvet antler possess biological effects. However, data regarding its anti-migration activity on prostate cancer is scarce. In this study, we investigated the inhibitory effect of top DVA (T-DVA) on the expression of prostate-specific antigen (PSA) and migration-related genes in the human prostate cancer cell, LNCaP. The T-DVA down-regulated the expression of PSA. In addition, the Radius(TM) assay revealed that T-DVA inhibited the migration behavior of prostate cancer cells. Furthermore, the expression of matrix metalloproteinase (MMP)-9 and vascular endothelial growth factor (VEGF) was also decreased with T-DVA. On the contrary, T-DVA increased the tissue inhibition of metalloproteinase (TIMP)-1 and (TIMP)-2. Taken together, our findings indicate that the T-DVA possesses anti-migration activity on prostate cancer cells. This is the first study of DVA to report the anti-migration activity on prostate cancer.

Abstract
Oxidized low-density lipoprotein (ox-LDL)-induced macrophage foam cell formation and injury is one of the major atherogenic factors. This study is aimed to investigate the protective effect of celery seed extract (CSE) on ox-LDL-induced injury of macrophages and the underlying signaling pathway. RAW264.7 macrophages were pre-incubated with CSE for 24 h, followed by stimulation with ox-LDL. Oil red O staining and enzymatic colorimetry indicated CSE significantly lessened lipid droplets and total cholesterol (TC) content in ox-LDL-injured macrophages. ELISA revealed that CSE decreased the secretion of inflammatory cytokine TNF-α and IL-6 by 12–27% and 5–15% respectively. MTT assay showed CSE promoted cell viability by 16–40%. Cell apoptosis was also analyzed by flow cytometry and laser scanning confocal microscope and the data indicated CSE inhibited ox-LDL-induced apoptosis of macrophages. Meanwhile, western blot analysis showed CSE suppressed NF-κBp65 and notch1 protein expressions stimulated by ox-LDL in macrophages. These results suggest that CSE inhibits ox-LDL-induced macrophages injury via notch1/NF-κB pathway.

Abstract
Pulmonary arterial hypertension (PAH) is a disease of the small pulmonary arteries characterized by increased vascular resistance. Pulmonary vasoconstriction has been proven to play a pivotal role in PAH. We have previously hypothesized that Panax notoginseng saponins (PNS) might attenuate hypoxia-hypercapnia-induced pulmonary vasoconstriction. The specific objective of the present study was to investigate the role of notoginsenoside R1, a main ingredient of PNS, in this process and the possible underlying mechanism. The third order pulmonary rings from the Sprague-Dawley rats were treated with different concentrations of notoginsenoside R1 (8, 40, and 100 mg/L, respectively) both before and during the conditions of hypercapnia and hypoxia. Contractile force changes in the rings were detected and the optimal concentration (8 mg/L) was selected. Furthermore, an ERK inhibitor, U0126, was applied to the rings. In addition, pulmonary arterial smooth muscle cells (PASMCs) were cultured under hypoxic and hypercapnic conditions, and notoginsenoside R1 was administered to detect the changes induced by ERK1/2. The results revealed biphasic vasoconstriction in rings under hypoxic and hypercapnic conditions. It is hypothesized that the observed attenuation of vasoconstriction and the production of vasodilation could have been induced by notoginsenoside R1. This effect was found to be significantly reinforced by U0126 (p < 0.05 or p < 0.01). ERK expression in the PASMCs under hypoxic and hypercapnic conditions was significantly activated (p < 0.05 or p < 0.01) and the observed activation was attenuated by notoginsenoside R1 (p < 0.05 or p < 0.01). Our findings strongly support the significant role of notoginsenoside R1 in the inhibition of hypoxia-hypercapnia-induced vasoconstriction by the ERK pathway.

Abstract
Abnormal proliferation of vascular smooth muscle cells (VSMCs) results in intimal thickening of the aorta, which may lead to arteriosclerosis. Therefore, VSMC antiproliferative agents may be efficient in the prevention and treatment of arteriosclerosis. Puerariae radix (PR) is the dried root of Pueraria lobata Ohwi or Pueraria thomsonii Benth. Flavones are the main components of PR and have been shown to have a protective effect on vascular disorders in traditional Chinese medicine treatments. However, the underlying molecular mechanism remains unclear. The aim of the present study was to explore the effect of PR flavone (PRF) on platelet-derived growth factor (PDGF)-BB-induced VSMC proliferation. PDGF-BB (25 ng/ml) and different doses of PRF (10, 50, 100 and 200 ng/ml) were used to treat VSMCs. The results revealed that PRF notably inhibited the PDGF-BB-induced VSMC proliferation and induced a cell cycle arrest at growth 1 phase of the cell cycle. In addition, cell cycle-associated proteins, including cyclin D1, proliferating cell nuclear antigen and cyclin-dependent kinase 4, were found to be downregulated. Furthermore, PRF inhibited the PDGF-BB-stimulated downregulation of VSMC markers, including α-smooth muscle actin, desmin and smoothelin. PDGF-BB upregulated the phosphorylation levels of phosphatidylinositide 3-kinase (PI3K) and extracellular signal-regulated kinase (ERK), which are associated with cell proliferation; however, these were decreased following PRF treatment. These observations indicated that PRF had a suppressive effect on PDGF-BB-induced VSMC proliferation by inhibiting PI3K and ERK pathways.

Abstract
Astragaloside IV (AS-IV), the major active component extracted from Astragalus membranaceus, has been demonstrated to exhibit protective effects on the cardiovascular, immune, digestive and nervous systems; thus, has been widely used in traditional Chinese medicine. Abnormal proliferation and migration of vascular smooth muscle cells (VSMCs) is closely associated with the initiation and progression of cardiovascular diseases, including atherosclerosis and restenosis. However, the effects of AS-IV on VSMCs remain unknown. For the first time, the present study demonstrated that AS-IV markedly suppressed platelet-derived growth factor (PDGF)-BB-stimulated cellular proliferation and migration of HDMEC-a human dermal VSMCs (HDVSMCs). Further investigation into the underlying molecular mechanisms demonstrated that the administration of AS-IV attenuated the PDGF-BB-stimulated switch of HDVSMCs into a proliferative phenotype. Furthermore, AS-IV inhibited the PDGF-BB-induced expression of cell cycle-associated proteins, as well as the upregulation of matrix metalloproteinase (MMP)2, but not MMP9. In addition, AS-IV was shown to downregulate the activation of p38 mitogen-activated protein kinase (MAPK) signaling induced by PDGF-BB in HDVSMCs. Therefore, the observations of the present study indicate that AS-IV inhibits PDGF-BB-stimulated VSMC proliferation and migration, possibly by inhibiting the activation of the p38 MAPK signaling pathway. Thus, AS-IV may be useful for the treatment of vascular diseases.

Abstract
The abnormal proliferation and migration of vascular smooth muscle cells (VSMCs) are key pathological factors in the initiation and progression of vascular disorders, including arteriosclerosis and restenosis following percutaneous coronary intervention (PCI). Hydroxysafflor yellow A (HSYA), the main component of the safflower yellow pigments, has widely been used for the treatment of cardiovascular diseases in traditional Chinese medicine. However, to the best of our knowledge, there are no studies investigating the pharmaceutical effect of HSYA on VSMCs or the underlying molecular mechanism. The present study aimed to investigate the effect of HSYA on platelet‑derived growth factor (PDGF)‑BB‑stimulated VSMC proliferation and migration. HSYA significantly inhibited PDGF‑BB‑stimulated VSMC proliferation and, in response to PDGF‑BB‑stimulation, VSMCs dedifferentiated into a proliferative phenotype. However, HSYA effectively reversed this phenotype switching. In addition, the production of nitrous oxide and cyclic guanosine monophosphate induced by PDGF‑BB was also suppressed by HSYA, and HSYA markedly inhibited PDGF‑BB‑stimulated VSMC migration. Investigation of the molecular mechanism revealed that HSYA inhibited PDGF‑BB‑induced activation of Akt signaling. In addition, HSYA also suppressed PDGF‑BB‑stimulated upregulation of cell cycle related proteins and heme oxygenase‑1. In conclusion, HSYA was able to inhibit PDGF‑BB‑stimulated VSMC proliferation and migration, partially via suppressing PDGF‑BB‑induced Akt signaling activation. Therefore, HSYA may be useful for the prevention and treatment of cardiovascular diseases, including atherosclerosis and restenosis following PCI.
