PURPOSE FBW7 functions as a tumor suppressor by targeting oncoproteins for destruction. We previously reported that the oncogenic mutation of KRAS inhibits the tumor suppressor FBW7 via the Ras-Raf-MEK-ERK pathway, which facilitates the proliferation and survival of pancreatic cancer cells. However, the underlying mechanism by which FBW7 suppresses(More)
AIM To investigate the change of HBV DNA, PCNA and GST-pi in chronic liver disease and hepatocellular carcinoma (HCC). METHODS Hepatitis B surface antigen (HBsAg), proliferating cell nuclear antigen (PCNA) and glutathione S-transferases (GST-pi) were detected by immunohistochemical staining and HBV DNA was detected by in situ hybridization (ISH) in(More)
Cancer metastasis is a prominent feature of cancer cells, which is responsible for most cancer -associated mortality. Epithelial-mesenchymal transition (EMT) plays an essential role in the initiation and development of cancer metastasis. Studies have shown that EMT can induce cancer metastasis by promoting tumor malignances, reprograming cancer metabolism,(More)
BACKGROUND & OBJECTIVE The expression of glutathione S-transferases(GST-pi) might abnormally increase in many carcinogenesis, and the alteration of GST-pi preceded than that alteration of cell morphology. This study was designed to investigate the expression of glutathione S-transferases (GST-pi) and its relationship with hepatitis B virus (HBV) infection(More)
Mercury (Hg) accumulation records spanning the last 16,000 years before present (yr BP, relative to AD 1950) were derived from a peat core collected from Dajiuhu mire, central China. The natural Hg concentration and accumulation rate (free from anthropogenic influence) were 135.5 ± 53.9 ng g(-1) and 6.5 ± 4.5 μg m(-2) yr(-1), respectively. The increase in(More)
SETD8 is a methyltransferase that specifically catalyzes the monomethylation of lysine 20 on histone H4. Previous studies have demonstrated that SETD8 is associated with proper cell cycle progression, DNA damage response, and transcriptional regulation. A recent study revealed that SETD8 played an important role in epithelial-mesenchymal transition (EMT) in(More)
Regulatory T cells (Tregs), particularly the CD4+CD25+Foxp3+ Tregs, down regulate immunity and promote tumor cell growth by directly suppressing CD8+ and CD4+ T cells. Alternatively they can promote tumor growth by generating interleukin-10 (IL-10) and transforming growth factor β (TGFβ) in situ, which help tumor cells to evade the immune system. In vivo(More)
