BACKGROUND Hydrogen sulfide (H(2)S) displays vasodilative, anti-oxidative, anti-inflammatory and cytoprotective activities. Impaired production of H(2)S contributes to the increased intrahepatic resistance in cirrhotic livers. The study aimed to investigate the roles of H(2)S in carbon tetrachloride (CCl(4))-induced hepatotoxicity, cirrhosis and portal(More)
B7-H4 is one of the most recently identified members of B7 superfamily of costimulatory molecules serving as an inhibitory modulator of T-cell response. B7-H4 is broadly expressed in human peripheral tissues and inducibly expressed in immune cells. The expression of B7-H4 has been observed in various types of human cancer tissues, and its soluble form has(More)
S-phase kinase-associated protein-2 (Skp2) is overexpressed in human cancers and associated with poor prognosis. Skp2 acts as an oncogenic protein by enhancing cancer cell growth and tumor metastasis. The present study has demonstrated that small hairpin RNA (shRNA)-mediated downregulation of Skp2 markedly inhibits the viability, proliferation, colony(More)
Developmentally regulated endothelial cell locus-1 (Del1) is an embryonic angiogenic factor expressed in early embryonic endothelial cells, but recently has been found to be expressed in some forms of cancers including colon and breast cancers, and melanoma, and human cancer cell lines. Overexpression of Del1 accelerates tumor growth by enhancing vascular(More)
The traditional k-means algorithm has sensitivity to the initial start center. To solve this problem, this paper proposed a new method to find the initial center and improve the sensitivity to the initial centers of k-means algorithm. The algorithm first computes the density of the area where the data object belongs to; then it finds k data objects, which(More)
BACKGROUND Cyclooxygenase (COX)-2 is overexpressed in many types of cancers including hepatocellular carcinoma (HCC). Meloxicam, a selective COX-2 inhibitor, has shown potential therapeutic effects against HCC, but the mechanisms accounting for its anti-cancer activities remain unclear. METHODS AND FINDINGS Meloxicam inhibited the ability of human HCC(More)
BACKGROUND Neuropilin-1 (NRP-1) is a transmembrane glycoprotein participating in the growth and metastasis of cancer cells as multifunctional co-receptors by interacting with the signaling pathways. However, its role in gastric cancer has not yet been clarified. This study aims to investigate whether NRP-1 expression is associated with the clinicopathology(More)
CCL18 is a member of CCL chemokines and is frequently overexpressed in cancer. Elevated CCL18 expression has been reported to be associated with poor prognosis of gastric cancer. However, the molecular mechanisms of CCL18 in gastric cancer cells remain elusive. In our study, we found that CCL18 was highly expressed in different gastric cancer cells. CCL18(More)
Cabozantinib is a multi-targeted tyrosine kinase inhibitor targeting vascular endothelial growth factor (VEGF) receptor (VEGFR)-2, MET (c-Met, also called hepatocyte growth factor (HGF) receptor), and other receptor tyrosine kinases. Cabozantinib has recently been approved for treating advanced medullary thyroid carcinoma (MTC), but its long-term benefit(More)
Sorafenib resistance remains a major obstacle for the effective treatment of hepatocellular carcinoma (HCC), and a number of miRNAs contribute to this resistance. However, the regulatory networks of miRNAs are very complex, thus inhibiting a single miRNA may sequentially activate other compensatory pathways. In the present study, we generated an artificial(More)
