UNLABELLED The ankyrin-repeat-containing, SH3-domain-containing, and proline-rich-region-containing protein (ASPP) family of proteins regulates apoptosis through interaction with p53 and its family members. This study evaluated the epigenetic regulation of ASPP1 and ASPP2 in hepatitis B virus (HBV)-positive hepatocellular carcinoma (HCC) and explores the(More)
BACKGROUND & AIMS iASPP is an inhibitory member of the ankyrin-repeat-, SH3-domain- and proline-rich-region-containing protein (ASPP) family; iASPP expression is up-regulated in different human tumor types. We explored the molecular mechanism increased expression of iASPP and its role in hepatocellular carcinoma (HCC). METHODS iASPP expression levels in(More)
PURPOSE To investigate Tip30 promoter methylation status in human hepatocellular carcinoma (HCC) and the correlation with clinicopathologic features and prognosis. EXPERIMENTAL DESIGN The methylation status of CpG islands in Tip30 promoter was examined in 15 HCC cell lines as well as 59 paired HCC and adjacent nontumor tissues. The associations between(More)
Epithelial to mesenchymal transition (EMT), and the reverse mesenchymal to epithelial transition (MET), are known examples of epithelial plasticity that are important in kidney development and cancer metastasis. Here we identify ASPP2, a haploinsufficient tumour suppressor, p53 activator and PAR3 binding partner, as a molecular switch of MET and EMT. ASPP2(More)
BACKGROUND & AIMS Expression of osteopontin correlates with tumor progression and metastasis. The mechanisms by which osteopontin promotes tumor cell survival remain unclear. Here we used short-hairpin RNA-mediated gene silencing to investigate the antitumor effects by osteopontin depletion in hepatocellular carcinoma (HCC). METHODS We applied(More)
UNLABELLED It has been previously demonstrated that the 30-kDa Tat-interacting protein (TIP30) plays an important role in the suppression of hepatocarcinogenesis by acting as a tumor suppressor. Here we report that TIP30 suppresses metastasis of hepatocellular carcinoma (HCC) through inhibiting the transcription of osteopontin (OPN), a key molecule in the(More)
Reactive oxygen species (ROS) and cellular oxidant stress have long been associated with cancer. Here, we show that TIP30, also called CC3, regulates p53 mRNA stability and induces apoptosis by sensing of intracellular oxidative stress in human hepatocellular carcinoma (HCC) cells. Introduction of TIP30 induced more cell death in HepG2 cells with a high(More)
Lysyl oxidase (LOX) is frequently overexpressed in a variety of malignancies and involved in tumor invasion and metastasis. Furthermore, it has been shown that LOX is closely related to vascular endothelial growth factor (VEGF). In this study, we aimed to investigate the exact role of LOX and the correlation between LOX and VEGF in hepatocellular carcinoma(More)
With the deployment of two ways HFC network and the development of digital TV, more and more interactive applications are being developed based on bi-directional HFC network. And the implementation of interactive cable set-top-box of digital TV is one of key component, which offers various interactive services based on TV display. In this paper, we(More)
BACKGROUND A quantity of case-control studies have been performed to address the association between three cyclooxygenase-2(COX-2) polymorphisms (-1195G/A, -765G/C and +8473T/C) and the risk of hepatocellular carcinoma (HCC). However, previous research results are inconsistent. We conducted this meta-analysis to clarify the correlation between these COX-2(More)
