BACKGROUND We previously showed microRNAs (miRNAs) in plasma are potential biomarkers for colorectal cancer detection. Here, we aimed to develop specific blood-based miRNA assay for breast cancer detection. METHODOLOGY/PRINCIPAL FINDINGS TaqMan-based miRNA profiling was performed in tumor, adjacent non-tumor, corresponding plasma from breast cancer(More)
Recent evidence suggests that a subpopulation of cancer cells, cancer stem cells (CSCs), is responsible for tumor growth in colorectal cancer. However, the role of CSCs in colorectal cancer metastasis is unclear. Here, we identified a subpopulation of CD26(+) cells uniformly present in both the primary and metastatic tumors in colorectal cancer patients(More)
BACKGROUND & AIMS To assess the safety and efficacy of transarterial chemoembolization (TACE) using doxorubicin-eluting beads (DEB) for hepatocellular carcinoma (HCC). METHODS Patients with incurable HCC and Child-Pugh class A cirrhosis were considered eligible for this phase I/II trial. Two courses of TACE using DEB were given at an interval of 2 months,(More)
BACKGROUND Radiofrequency ablation (RFA) is a recently developed treatment for hepatocellular carcinoma (HCC). Thus far, the prognostic impact of tumor biomarkers has not been evaluated in this treatment. High serum level of vascular endothelial growth factor (VEGF) has been shown to predict microscopic vascular invasion and metastasis in HCC. This study(More)
BACKGROUND AND AIMS Cancer invasion and metastasis may associate with the phenotype transition called epithelial-mesenchymal transition (EMT). We aim to evaluate the impact of four-and-a-half LIM protein 2 (FHL2) on EMT and invasion of colon cancer. METHODS The functional role of FHL2 in EMT was determined by overexpression or small interfering(More)
Research over the past decade has unraveled important molecular pathways involved in hepatocellular carcinoma (HCC), and several chromosomal and genetic aberrations have been identified to be responsible for initiation of the carcinogenic process. HBx protein and HCV core protein appear to play a pivotal role in hepatocarcinogenesis related to hepatitis B(More)
Hepatocellular carcinoma (HCC) is a common cancer in the world due to high prevalence of hepatitis B or C virus infection. Research in recent years has uncovered important molecular pathways involved in development and progression of HCC. Several genetic aberrations and molecular mechanisms responsible for initiation of hepatocarcinogenesis have been(More)
Hepatocellular carcinoma (HCC) is characterized as a highly chemoresistant cancer with no effective systemic therapy. Despite surgical or locoregional therapies, prognosis remains poor because of high tumor recurrence or tumor progression, and currently there are no well-established effective adjuvant therapies. The molecular biology of carcinogenesis and(More)
Down-regulation of XIAP (X-linked inhibitor of apoptosis protein) sensitizes colon cancer cells to the anticancer effect of peroxisome proliferator-activated receptor-gamma (PPARgamma) ligands in mice. The aims of this study were to evaluate the effect of embelin (2,5-dihydroxy-3-undecyl-1,4-benzoquinone), an antagonist of XIAP, on colon cancer, with a(More)
This study evaluated the significance of circulating bone marrow-derived endothelial progenitor cells (EPCs) in patients with hepatocellular carcinoma (HCC), a solid tumor with rich neovasculature. Eighty patients with HCC were recruited for the study, and 16 patients with liver cirrhosis and 14 healthy subjects were also included for comparison. Blood(More)
