Sphingosine-1-phosphate (S1P) is an amphiphilic signaling molecule, which is enriched in functional high density lipoprotein (HDL) and shows arterial protection. The distribution of S1P is changed with increased plasma phospholipid transfer protein (PLTP) activity and impaired HDL function in patients with coronary heart diseases. Therefore, we hypothesized(More)
Celastrus orbiculatus Thunb. (COT), a traditional Chinese herb, has anti-inflammatory and anti-oxidative properties. In this study, we examined the protective effect of COT on the initiation of atherosclerosis induced by high fat diet and explored the underlying mechanisms. We established guinea pig models of hyperlipidemia and treated them with three(More)
The study aimed to investigate the effect of niacin on vascular inflammatory lesions in vivo and in vitro as well as its lipid-regulating mechanism. In vivo study revealed that niacin downregulated the levels of inflammatory factors (IL-6 and TNF-α) in plasma, suppressed protein expression of CD68 and NF-κB p65 in arterial wall, and attenuated oxidative(More)
Genome editing is a valuable technique for gene function analysis and crop improvement. Over the past two years, the CRISPR-Cas9 system has emerged as a powerful tool for precisely targeted gene editing. In this study, we predicted 11 U6 genes in soybean (Glycine max L.). We then constructed two vectors (pCas9-GmU6-sgRNA and pCas9-AtU6-sgRNA) using the(More)
BACKGROUND Statins are first-line pharmacotherapeutic agents for hypercholesterolemia treatment in humans. However the effects of statins on atherosclerosis in mouse models are very paradoxical. In this work, we wanted to evaluate the effects of simvastatin on serum cholesterol, atherogenesis, and the expression of several factors playing important roles in(More)
The high mobility group-box 3 (HMGB3) protein belongs to the high mobility group box (HMG-box) subfamily, and recent studies have shown that HMGB3 is an oncogene for leukemia. HMGB3 is also expressed at a high level in the progression phase of breast and gastric cancer (GC). Using bioinformatic analyses, we found that HMGB3 is a potential target for(More)
BACKGROUND It is designed to investigate the effects of combination therapy of allicin and fenofibrate on the endothelial and liver functions in rats with hyperlipidemia. METHODS The healthy male Wistar rats fed high fat diet were treated with fenofibrate (80 mg/kg per day) alone, allicin (60 mg/kg per day) alone and a lower dosage of combined therapy(More)
Oxidative stress plays an important role in the progression of HIV-1 infection. Nicotine can either protect neurons from neurodegeneration or induce oxidative stress, depending on its dose and degree of oxidative stress impairment. However, the relationship between nicotine and oxidative stress in the HIV-1-infected individuals remains largely unknown. The(More)
Chronic excessive fluoride intake is known to be toxic, and effects of long-term fluorosis on different organ systems have been examined. However, there are few studies about the effects of fluorosis on cardiovascular systems. Here, we studied the fluoride-induced apoptosis in H9c2 cells and determined the underlying molecular mechanisms including the cell(More)
The single and combined effects of scavenger receptor-BI (SR-BI), ATP-binding cassette transporter (ABC) A1 and G1 on cholesterol efflux from Chinese Hamster Ovary (CHO) cells were investigated. When apolipoproteinA-I (apoA-I) was used as an acceptor, ABCA1 overexpression led to an increase in total cholesterol (TC) in medium which is attributable to a(More)
