BACKGROUND Inhibiting the action of proprotein convertase subtilisin/kexin type 9 (PCSK9) on the low-density lipoprotein receptor (LDLR) has emerged as a novel therapeutic target for hypercholesterolemia. Here we investigated the effect of berberine, natural plant extracts, on PCSK9-LDLR pathway in C57BL/6 mice with lipopolysaccharide (LPS) induced(More)
Long non-coding RNAs (lncRNAs) are key regulatory molecules involved in a variety of biological processes and human diseases. However, the pathological effects of lncRNAs on primary varicose great saphenous veins (GSVs) remain unclear. The purpose of the present study was to identify aberrantly expressed lncRNAs involved in the prevalence of GSV(More)
Previous studies show that several pathways are involved in sanguinarine-induced apoptotic cell death, including AKT downregulation, inhibition of NF-kB activation, mediation of ROS production, downregulation of anti-apoptosis proteins XIAP and cIAP-1, upregulation of BAX, and downregulation of BCL2. In this study, we found out that the quenching of ROS(More)
BACKGROUND Heart failure (HF) is approaching an epidemic proportion and has become one of the leading causes of death. It imposes a great burden on the healthcare system and society. Remodeling of cardiomyocyte membranes has a profound role in the pathogenesis of HF. However, whether dynamin (DNM), a membrane-remodeling GTPase, is associated with HF remains(More)
Mastitis is the inflammation of the mammary gland. Recent research has shown that Angiopoietin-like protein 2 (ANGPTL2) is a key inflammatory mediator. In the present study, we tested whether there is a correlation between increased ANGPTL2 expression and inflammation in response to Staphylococcus aureus in murine mastitis and the mechanisms involved.(More)
The purpose of this study was to investigate the possibility that oxidative stress was involved in danofloxacin-induced toxicity in renal tubular cells epithelial cell line (LLC-PK1). Confluent LLC-PK1 cells were incubated with various concentrations of danofloxacin. The extent of oxidative damage was assessed by measuring the reactive oxygen species (ROS)(More)
UNLABELLED Although sanguinarine (SANG) can be transformed to dihydrosanguinarine (DHSA) in human and animals, the enzyme involved in the imine bond reduction of SANG is still unknown. In this study, we found that rat NAD(P)H quinone oxidoreductase 1 expressed by prokaryotic system can transform SANG to DHSA in an NADPH dependent manner. We also found out(More)
