TLR4 (Toll-like receptor 4) and B7-H1, which were known to be restricted to immune cells in the past, were found to be aberrantly expressed in a majority of tumor cells, facilitating tumor evasion from immune surveillance. Our study demonstrated that activation of TLR4 signaling in bladder cancer cells up-regulated B7-H1 expression. Furthermore, this(More)
Alzheimer's disease (AD) is characterized by the accumulation of β-amyloid peptide (Aβ) and loss of neurons. Recently, a growing body of evidences have indicated that as a herbal compound naturally derived from grapes, resveratrol modulates the pathophysiology of AD, however, with a largely unclear mechanism. Therefore, we aimed to investigate the(More)
Toll-like receptor 4 (TLR4) was found to be aberrantly expressed in bladder cancer, inducing some genes expression and facilitating tumor progression. Recent data suggest that tumor associated Interleukin-6 (IL-6) correlates with tumor size and grade in bladder cancer. However, the molecule mechanisms of the induction of IL-6 response in bladder cancer(More)
Curcumin has been shown to have high cytotoxicity towards various cancer cell lines, but its water insolubility and instability make its bioavailability exceedingly low and, thus, it is generally inactive in in vivo anticancer tests. Here, we report an intracellular-labile amphiphilic surfactant-like curcumin prodrug--curcumin conjugated with two short(More)
Alzheimer’s disease (AD) is characterized by the accumulation of b-amyloid peptide (Ab) and loss of neurons. Recently, a growing body of evidences have indicated that as a herbal compound naturally derived from grapes, resveratrol modulates the pathophysiology of AD, however, with a largely unclear mechanism. Therefore, we aimed to investigate the(More)
Recent studies have suggested that neurodegeneration is involved in the pathogenesis of schizophrenia, and some atypical antipsychotics appear to prevent or retard progressive morphological brain changes. However, the underlying molecular mechanisms are largely unknown. Whether changes in intracellular signaling pathways are related to their neuroprotective(More)
Resveratrol (3,5,4'-tihydroxy-trans-stilbene), a polyphenolic phytoalexin found in the skin and seeds of grapes, has been reported to possess a wide range of biological and pharmacological activities including antioxidant, anti-inflammatory, and antimutagenic effects. The present study intended to explore the neuroprotective effects of resveratrol against(More)
Hepatocellular carcinoma (HCC) is a highly aggressive malignancy. Nanosecond pulsed electric field (nsPEF) is a new technology destroying tumor cells with a non-thermal high voltage electric field using ultra-short pulses. The study's aim was to evaluate the ablation efficacy of nsPEFs with human HCC cell lines and a highly metastatic potential HCC(More)
Cholestatic liver fibrosis was achieved by bile duct ligation (BDL) in mice. Liver injury associated with BDL for 15 days included significant reactive oxygen/nitrogen species generation, liver inflammation, cell death and fibrosis. Administration of Epigallocatechin 3-Gallate (EGCG) in animals reduced liver fibrosis involving parenchymal cells in BDL(More)
The non-classical human leukocyte antigens (HLA)-E, HLA-G, and HLA-F have been shown to modulate immune responses. We examined whether non-classical HLA polymorphisms are associated with hepatitis B virus (HBV) infection and hepatocellular carcinoma (HCC). Fifteen Single-nucleotide polymorphisms (SNPs) in these non-classical class I alleles were(More)
