Purpose: The overexpression of hypoxia-inducible factor 1a (HIF-1a) is a common finding in hepa-tocellular carcinoma (HCC), and it leads to angiogenesis and poor prognosis. Sorafenib, a multikinase inhibitor, has shown significant improvement in survival in patients with advanced HCC in clinical trials. However, the mechanisms that account for the(More)
SB203580 is a well-known inhibitor of p38 mitogen-activated protein kinase (MAPK). However, it can suppress cell proliferation in a p38 MAPK independent manner. The inhibitory mechanism remains unknown. Here, we showed that SB203580 induced autophagy in human hepatocellular carcinoma (HCC) cells. SB203580 increased GFP-LC3-positive cells with GFP-LC3 dots,(More)
BACKGROUND Biomarkers for accurate diagnosis of early hepatocellular carcinoma (HCC) are limited in number and clinical validation. We applied SELDI-TOF-MS ProteinChip technology to identify serum profile for distinguishing HCC and liver cirrhosis (LC) and to compare the accuracy of SELDI-TOF-MS profile and alpha-fetoprotein (AFP) level in HCC diagnosis.

Hepatocellular carcinoma (HCC) is the fifth common cancer. The differential expression of microRNAs (miRNAs) has been associated with the prognosis of various cancers. However, limited information is available regarding genome-wide miRNA expression profiles in HCC to generate a tumor-specific miRNA signature of prognostic values. In this study, the miRNA(More)
BACKGROUND The biological pathways and functional properties by which misexpressed microRNAs (miRNAs) contribute to liver carcinogenesis have been intensively investigated. However, little is known about the upstream mechanisms that deregulate miRNA expressions in this process. In hepatocellular carcinoma (HCC), hepatitis B virus (HBV) X protein (HBx), a(More)
Liver cancer ranks in prevalence and mortality among top five cancers worldwide. Accumulating interests have been focused in developing new strategies for liver cancer treatment. We have previously showed that dihydroartemisinin (DHA) exhibited antitumor activity towards liver cancer. In this study, we demonstrated that histone deacetylase inhibitors(More)
Long noncoding RNAs (lncRNAs) regulate gene expression by acting with microRNAs (miRNAs). However, the roles of cancer specific lncRNA and its related competitive endogenous RNAs (ceRNA) network in hepatocellular cell carcinoma (HCC) are not fully understood. The lncRNA profiles in 372 HCC patients, including 372 tumor and 48 adjacent non-tumor liver(More)
Previous studies have showed that the renin-angiotensin system (RAS) plays an important role in the pathogenesis of liver cirrhosis. The localization of angiotensin II receptor in hepatic stellate cells opens up a new research direction of RAS in the regulation of liver fibrosis. However, the potential role of angiotensin II on Kupffer cells remains(More)
BACKGROUND AND AIM Granulin-epithelin precursor (GEP) has previously been reported to control cancer growth, invasion, chemo-resistance, and served as novel therapeutic target for cancer treatment. However, the nature and characteristics of GEP interacting partner remain unclear. The present study aims to identify and characterize the novel predominant(More)
Four and a Half LIM protein 2 (FHL2) is a LIM domain only protein that is able to form various protein complexes and regulate gene transcription. Recent findings showed that FHL2 is a potential tumor suppressor gene that was down-regulated in hepatocellular carcinoma (HCC). Moreover, FHL2 can bind to and activate the TP53 promoter in hepatic cells. In this(More)
