With the development of the techniques of Event Detection and Tracking, it is feasible to gather text information from many sources and structure it into events which are constructed online automatically and updated temporally. There are always diversified versions to describe an event and users usually are eager to know all the versions. With the huge(More)
Hepatocellular carcinoma (HCC) is generally acknowledged as the most common primary malignant tumor, and it is known to be resistant to conventional chemotherapy. Wentilactone B (WB), a tetranorditerpenoid derivative extracted from the marine algae-derived endophytic fungus Aspergillus wentii EN-48, has been shown to trigger apoptosis and inhibit metastasis(More)
Carnosine (β-alanyl-L-histidine), described as an enigmatic peptide for its antioxidant, anti-aging and especially antiproliferation properties, has been demonstrated to play an anti-tumorigenic role in certain types of cancer. However, its function in human gastric carcinoma remains unclear. In this study, the effect of carnosine on cell proliferation and(More)
Versican, a ubiquitous component of the extracellular matrix (ECM), accumulates both in tumor stroma and cancer cells and is highly regulated by various cytokines. The aberrant expression of versican and its isoforms is known to modulate cell proliferation, differentiation, and migration, all of which are features of the invasion and metastasis of cancer;(More)
We have examined the effect of adenoviruses expressing soluble transforming growth factor receptorII-Fc (sTGFβRIIFc) in a 4T1 mouse mammary tumor bone metastasis model using syngeneic BALB/c mice. Infection of 4T1 cells with a non-replicating adenovirus, Ad(E1-).sTβRFc, or with two oncolytic adenoviruses, Ad.sTβRFc and TAd.sTβRFc, expressing sTGFβRIIFc (the(More)
The effects of inflammation may not always benefit the individual. Its amplifying nature represents a highly regulated biological program, and the inflammatory microenvironment is its essential component. Growing evidence suggests that the ECM (extracellular matrix) is important for the early steps of inflammation. Versican, a ubiquitous component of the(More)
Classical neurodegenerative diseases such as Alzheimer's, Parkinson's, and Huntington's are most commonly seen in older persons. The incidence rate increases as life expectancy increases. Even though neuronal loss, neuronal death and accumulated toxic proteins are well investigated, the mechanism(s) of neurodegenerative disorders is not yet fully(More)
We were interested in developing oncolytic adenoviral vectors that can be administered systemically for the treatment of breast cancer. To restrict viral replication in breast tumor cells, we constructed mhTERTAd.sTbetaRFc, a 01/07-based adenoviral vector expressing the soluble form of transforming growth factor-beta (TGFbeta) receptor II fused with the(More)
Aberrant protein glycosylation plays major roles in neurodegenerative diseases, including Parkinson's disease (PD). Glycoproteomics showed that the glycosylation of sodium channel β4 was significantly increased in human brain tissue. β4-specific antibodies reacted in immunoblot assays with the 35- and 38-kDa bands from the membrane fractions isolated from(More)
To discover candidate biomarkers for diagnosis and detection of human laryngeal carcinoma and explore possible mechanisms of this cancer carcinogenesis, two-dimensional strong cation-exchange/reversed-phase nano-scale liquid chromatography/mass spectrometry analysis was used to identify differentially expressed proteins between the laryngeal carcinoma(More)
