Hydroxysafflor yellow A (HYSA) inhibited the proliferation and differentiation of 3T3-L1 preadipocytes.[Pubmed: 25749912]Cytotechnology. 2015 Oct;67(5):885-92. Hydroxysafflor yellow A (HSYA), a main component of safflor yellow, has been demonstrated to prevent steroid-induced avascular necrosis of femoral head by inhibiting primary bone marrow-derived mesenchymal stromal cells adipogenic differentiation induced by steroid. METHODS AND RESULTS:In this study, we investigate the effect of Hydroxysafflor yellow A on the proliferation and adipogenesis of mouse 3T3-L1 preadipocytes. The effects of Hydroxysafflor yellow A on proliferation and differentiation of 3T3-L1 cells and its possible mechanism were studied by 3-(4,5-dimethylthiazol-2-yl) 2,5-diphenyl tetrazolium bromide spectrophotometry, Oil Red O staining, intracellular triglyceride assays, real-time quantitative RT-PCR, transient transfection and dual luciferase reporter gene methods. Hydroxysafflor yellow A inhibited the proliferation of 3T3-L1 preadipocytes and cell viability greatly decreased in a dose and time dependent manner. Hydroxysafflor yellow A (1 mg/l) notably reduced the amount of intracellular lipid and triglyceride content in adipocytes by 21.3 % (2.13 ± 0.36 vs 2.71 ± 0.40, P < 0.01) and 22.6 % (1.33 ± 0.07 vs 1.72 ± 0.07, P < 0.01) on days 8 following the differentiation, respectively.Hydroxysafflor yellow A(1 mg/l) significantly increased hormone-sensitive lipase (HSL) mRNA expression and promoter activities by 2.4- and 1.55-fold, respectively (P < 0.01), in differentiated 3T3-L1 adipocytes. CONCLUSIONS: Hydroxysafflor yellow A inhibits the proliferation and adipogenesis of 3T3-L1 preadipocytes. The inhibitory action of Hydroxysafflor yellow A on adipogenesis may be due to the promotion of lipolytic-specific enzyme HSL expression by increasing HSL promoter activity.

Abstract

Hydroxysafflor Yellow A (HSYA), a most representative ingredient of Carthamus tinctorius L., had long been used in treating ischaemic cardiovascular diseases in China and exhibited prominently anticoagulant and pro‐angiogenic activities, but the underlying mechanisms remained largely unknown. This study aimed to further elucidate the pro‐angiogenic effect and mechanism of HSYA on ischaemic cardiac dysfunction. A C57 mouse model of acute myocardial infarction (AMI) was firstly established, and 25 mg/kg HSYA was intraperitoneally injected immediately after operation and given once, respectively, each morning and evening for 2 weeks. It was found that HSYA significantly improved ischaemia‐induced cardiac haemodynamics, enhanced the survival rate, alleviated the myocardial injury and increased the expressions of CD31, vascular endothelial growth factor‐A (VEGF‐A) and nucleolin in the ischaemic myocardium. In addition, HSYA promoted the migration and tube formation of human umbilical vein endothelial cells (HUVECs), enhanced the expressions of nucleolin, VEGF‐A and matrix metalloproteinase‐9 (MMP‐9) in a dose‐ and time‐dependent manner. However, down‐regulation of nucleolin expression sharply abrogated the effect mentioned above of HSYA. Further protein‐RNA coimmunoprecipitation and immunoprecipitation‐RT‐PCR assay showed that nucleolin binded to VEGF‐A and MMP‐9 mRNA and overexpression of nucleolin up‐regulated the mRNA expressions of VEGF‐A and MMP‐9 in the HUVECs through enhancing the stability of VEGF‐A and MMP‐9 mRNA. Furthermore, HSYA increased the mRNA expressions of VEGF‐A and MMP‐9 in the extract of antinucleolin antibody‐precipitated protein from the heart of AMI mice. Our data revealed that nucleolin mediated the pro‐angiogenic effect of HSYA through post‐transcriptional regulation of VEGF‐A and MMP‐9 expression, which contributed to the protective effect of HSYA on ischaemic cardiac dysfunction.

Abstract

Inhibition of the nucleotide pool sanitizing enzyme MTH1 causes extensive oxidative DNA damages and apoptosis in cancer cells and hence may be used as an anticancer strategy. As natural products have been a rich source of medicinal chemicals, in the present study, we used the MTH1-catalyzed enzymatic reaction as a high-throughput in vitro screening assay to search for natural compounds capable of inhibiting MTH1. Echinacoside, a compound derived from the medicinal plants Cistanche and Echinacea, effectively inhibited the catalytic activity of MTH1 in an in vitro assay. Treatment of various human cancer cell lines with Echinacoside resulted in a significant increase in the cellular level of oxidized guanine (8-oxoguanine), while cellular reactive oxygen species level remained unchanged, indicating that Echinacoside also inhibited the activity of cellular MTH1. Consequently, Echinacoside treatment induced an immediate and dramatic increase in DNA damage markers and upregulation of the G1/S-CDK inhibitor p21, which were followed by marked apoptotic cell death and cell cycle arrest in cancer but not in noncancer cells. Taken together, these studies identified a natural compound as an MTH1 inhibitor and suggest that natural products can be an important source of anticancer agents.

Abstract

Background and Aim
Type 2 diabetes mellitus (T2DM), a complex metabolic disease, has become a major public health issue around the world. Hydroxysafflor yellow A (HSYA) is the major active chemical ingredient of Carthamus tinctorius L. (safflower), which is widely used in patients with cardiovascular and cerebrovascular diseases in China. The aim of this study was to investigate the anti-diabetic effect and potential mechanism of HSYA on the high-fat diet (HFD) and streptozotocin (STZ-)-induced T2DM rats.

Materials and Methods
T2DM rats were induced by feeding HFD (60% fat) for four weeks followed by intraperitoneal injection of a low dose of streptozocin (35mg/kg). The T2DM rats were treated with HSYA (120mg/kg) or metformin (90mg/kg) for eight weeks. Biochemical analysis, histological analysis and Western blot analysis were conducted after 8 weeks of intervention.

Results
The treatment with HSYA evidently reduced fasting-blood glucose and insulin resistance in T2DM rats, indicated by results from fasting-blood glucose, oral glucose tolerance test, fasting insulin levels and histology of pancreas islets. The Western blot results revealed that HSYA reversed the down-regulation of PI3K and AKT in liver. The TUNEL assay analysis of pancreatic tissue showed that HSYA could inhibit the apoptosis of pancreatic β-cells to a certain extent. Moreover, HSYA-treatment increased the levels of glycogen synthase and hepatic glycogen and improved lipid metabolism by reducing the triglyceride, total and low-density lipoprotein cholesterol levels, even though it did not change the rats’ body weights.

Conclusion
The results of this study suggested that HSYA could promote PI3K/Akt activation and inhibit the apoptosis of pancreatic β-cells directly or indirectly, which might be the underlying mechanisms in HSYA to improve insulin resistance and regulate glycolipid metabolism in T2DM rats.
