Quantitative real-time reverse transcription-polymerase chain reaction (Q-PCR) has become an indispensable technique for accurate determination of gene expression in various samples. In mice, intravenous injection of concanavalin A (ConA) leads to acute hepatitis and liver injury. Functional studies based on this model have provided insights for(More)
BACKGROUND & AIMS Glucocorticoids have potent anti-inflammatory effects, but also can cause insulin resistance, osteoporosis, and muscle wasting, preventing their long-term use. Glucocorticoids also have been associated with the development of hepatic cholestasis and gallstone disease, but little is known about their pathogenic mechanisms. METHODS We(More)
This study was designed to investigate the hepatic protective effect and the molecular mechanisms of andrographolide in concanavalin A-induced liver injury model. Results showed that andrographolide (Ag) attenuated concanavalin A (Con-A)-induced liver injury and inhibited hepatocyte apoptosis. Further results showed that oxidative stress response genes were(More)
Andrographolide (AG), the primary bioactive component of Andrographils paniculate Nees, has showed an anti-diabetic effect. However, the molecular mechanism has not been clarified. In this study, we demonstrated that AG increased glucose uptake in 3T3-L1 cells in a time- and dosedependent manner. The activation of insulin signaling by AG was initiated from(More)
Osteonecrosis of the femoral head is a severely disabling complication of steroid immunosuppression in renal transplant patients. The increased number of patients undergoing transplantation has increased the number of transplant recipients undergoing total hip replacement arthroplasty (THRA). In this study, we retrospectively assessed patients who underwent(More)
Epothilone A (EpoA) is under investigation as an antitumor agent. To provide better understanding of the activity of EpoA against cancers, by theoretical studies such as using docking method, molecular dynamics simulation and density functional theory calculations, we identify several key residues located on β-tubulin as the active sites to establish an(More)
Gluconeogenesis is critical in maintaining blood glucose levels in a normal range during fasting. In this study, we investigated the role of Yin Yang 1 (YY1), a key transcription factor involved in cell proliferation and differentiation, in the regulation of hepatic gluconeogenesis. Our data showed that hepatic YY1 expression levels were induced in mice(More)
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is characterised by accumulation of excessive triglycerides in the liver. Obesity is usually associated with NAFLD through an unknown mechanism. OBJECTIVE To investigate the roles of Yin Yang 1 (YY1) in the progression of obesity-associated hepatosteatosis. METHODS Expression levels of hepatic YY1(More)
SUMOylation has been considered as an important mechanism to regulate multiple cellular processes, including inflammation. TAB2 (TAK1-binding protein 2) is an upstream adaptor protein in the IL-1 signaling pathway. Covalent modifications of TAB2 have not been well studied. In this study, we demonstrated that TAB2 could be modified by SUMO. Using Ubc9(More)
Andrographolide (AG), an active compound found in Andrographis paniculate Nees, has been shown to exert anti-inflammatory, anticancer and anti-hyperglycemic effects. However, its biological activities against obesity have not been reported. The purpose of this study was to investigate the effect of AG on the differentiation of 3T3-L1 preadipocytes. We found(More)
