Phosphatase and tensin homologue deleted on chromosome 10 (PTEN) has been reported to play a role in the suppression of activated hepatic stellate cells (HSCs). Moreover, it has been demonstrated that hypermethylation of the PTEN promoter is responsible for the loss of PTEN expression during HSC activation. Methylation is now established as a fundamental(More)
Epithelial-mesenchymal transition (EMT) was reported to be involved in the activation of hepatic stellate cells (HSCs), contributing to the development of liver fibrosis. Epithelial-mesenchymal transition can be promoted by the Hedgehog (Hh) pathway. Patched1 (PTCH1), a negative regulatory factor of the Hh signalling pathway, was down-regulated during liver(More)
Sodium butyrate (SB) has been widely used to treat cerebral diseases. The aim of the present study is to examine the neuroprotective effects of SB on early TBI in mice and to explore the underlying mechanisms of these effects. TBI was induced using a modified weight-drop method. Neurological deficits were evaluated according to the neurological severity(More)
BACKGROUND Chronic hepatitis B virus (HBV) infection is a known major etiological factor for hepatocellular carcinoma (HCC) development. Alpha-fetoprotein (AFP) is widely used to detect primary HCC, whereas its sensitivity and specificity are not satisfying. Recently, circulating microRNAs (miRNAs) have been reported to be promising biomarkers for(More)
Ischemia/reperfusion (I/R)-induced autophagy increases the severity of cardiomyocyte injury. The aim of this study was to investigate the effects of berberine, a natural extract from Rhizoma coptidis, on the I/R-induced excessive autophagy in in vitro and in vivo models. Autophagy was increased both in H9c2 myocytes during hypoxia/reoxygenation (H/R) injury(More)
The phagocytosis of oxidized low-density lipoprotein (oxLDL) by monocyte-derived macrophages and the subsequent differentiation of macrophages into foam cells are the key steps in atherogenesis. Scavenger receptors, such as CD36 and lectin-like low-density lipoprotein receptor 1 (LOX-1), are responsible for the uptake of oxLDL. Adipocyte enhancer-binding(More)
OBJECTIVE to study the oxidative stress of rats with acute paraquat poisoning and the intervention of Sodium Dimercaptopropane Sulfonate (NA-DMPS). METHODS Eighty male SD rats were randomizedly divided into: the normal control group (n=8), NA-DMPS control group (n=8), the PQ group (n=32, the rats were intraperitoneally injected with 1% PQ solution at the(More)
Accumulating evidence has demonstrated that naturally occurring CD4(+)CD25(+) regulatory T cells (Tregs) are critical for maintenance of immunological tolerance and have been shown to be important in regulating the immune responses in many diseases. Curcumin, a phytochemical obtained from the rhizome of the plant Curcuma longa, has achieved the potential(More)
Previously, we found that long intergenic noncoding RNA-p21 (lincRNA-p21) inhibits hepatic stellate cell (HSC) activation and liver fibrosis via p21. However, the underlying mechanism of the antifibrotic role of lincRNA-p21 in liver fibrosis remains largely unknown. Here, we found that lincRNA-p21 expression was significantly downregulated during liver(More)
