    ABSTRACT: Genome-wide association studies (GWAS) have recently identified KIF1B as susceptibility locus for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). To further identify novel susceptibility loci associated with HBV-related HCC and replicate the previously reported association, we performed a large three-stage GWAS in the Han Chinese population. 523,663 autosomal SNPs in 1,538 HBV-positive HCC patients and 1,465 chronic HBV carriers were genotyped for the discovery stage. Top candidate SNPs were genotyped in the initial validation samples of 2,112 HBV-positive HCC cases and 2,208 HBV carriers and then in the second validation samples of 1,021 cases and 1,491 HBV carriers. We discovered two novel associations at rs9272105 (HLA-DQA1/DRB1) on 6p21.32 (OR = 1.30, P = 1.13×10⁻¹⁹) and rs455804 (GRIK1) on 21q21.3 (OR = 0.84, P = 1.86×10⁻⁸), which were further replicated in the fourth independent sample of 1,298 cases and 1,026 controls (rs9272105: OR = 1.25, P = 1.71×10⁻⁴; rs455804: OR = 0.84, P = 6.92×10⁻³). We also revealed the associations of HLA-DRB1*0405 and 0901*0602, which could partially account for the association at rs9272105. The association at rs455804 implicates GRIK1 as a novel susceptibility gene for HBV-related HCC, suggesting the involvement of glutamate signaling in the development of HBV-related HCC.

    ABSTRACT: In the present study, polysaccharides were extracted from the Lycium chinensis (LCP). Rats were divided into four groups. Two groups (Groups A) were maintained on the basal diet, whereas the remaining three groups (Groups B, C and D) had free access to the basal diet and were orally fed with LCP at 200 mg/kg b.w. for Group B, 400 mg/kg b.w. for Group C and 600 mg/kg b.w. for Group D, respectively. Following 4 weeks of this dietary regimen, hepatocarcinogenesis was initiated in all animals by a single intraperitoneal DENA (Sigma-Aldrich, St. Louis, MO, USA) injection at a dose of 200 mg/kg body weight (mixed with peanut oil). Results still showed that L. chinensis polysaccharides (LCP) increased spleen, thymus indexs, antioxidant enzymes activities and decreased oxidative injury. In addition, LCP still significantly affect VEGF and Cyclin D1 proteins expression in liver cancer rats. It can be concluded that LCP exhibited remarkable protective effects against diethylnitrosamine (DEN)-induced oxidative hepatic injury in liver cancer rats.

    ABSTRACT: The presence of regulatory T cells in patients who received therapeutic cytokine-induced killer (CIK) cells may inhibit host immunity, leading to failed immunotherapy. In this study, we investigated the impact of using interleukin-6 (IL-6) on the phenotype alteration, proliferation, and cytotoxic activity of CIK cells generated from the peripheral blood mononuclear cells of patients with hepatocellular carcinoma. We found that addition of IL-6 to CIK-cell culture medium decreased the percentage of Treg/CD4(+), Treg/CD3(+) T cells in the resultant CIK cells and simultaneously increased the proliferation ability, the expression of CD45RO(+)CD62L(low)CCR7(low) effector memory phenotype, and cytotoxicity of the CIK cells against hepatocellular carcinoma in vitro. Our results also showed that the percentage of Th17/CD4(+) cells was increased in CIK cells, but the proportion of Th17/CD4(+) cells was not affected by the addition of IL-6 to CIK-cell culture medium. Collectively, these data suggest that IL-6 may have the potential to improve antitumor activity of CIK cells in cancer immunotherapy.

    ABSTRACT: This study evaluated the protective effects of aqueous extract of Lycium barbarum (LBAE) and ethanol extract of Lycium barbarum (LBEE) on blood lipid levels, serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) activities and liver tissue antioxidant enzyme activities in rats fed a high fat diet (HF). The rats were randomly divided into seven groups of ten rats each and fed a different diet for eight weeks as follows: One group (NC group) was fed a standard diet, one group was fed a high-fat diet (HF group), one group was fed a high-fat diet and orally fed with 20 mg/kg b.w. simvastatin (HF + simvastatin group), and the other group was fed the high fat diet and orally fed with 50 mg/kg b.w. or 100 mg/kg b.w. LBAE (HF + LBAE), or 50 mg/kg b.w. or 100 mg/kg b.w. LBEE (HF + LBEE), respectively. After eight weeks, the HF diet caused deleterious metabolic effects. Rats fed the HF diet alone showed increased hepatocellular enzyme activities in plasma, a significant decline in antioxidant enzyme activities, and elevated liver lipid peroxidation indices. LBAE and LBEE administration significantly reduced liver damage and oxidative changes, and brought back the antioxidants and lipids towards normal levels. These data suggest that these antioxidants protect against toxicity parameters in HF rats.
