Portal vein tumor thrombus (PVTT) is strongly correlated to a poor prognosis for patients with hepatocellular carcinoma (HCC). In this study, we uncovered a causative link between hepatitis B virus (HBV) infection and development of PVTT. Mechanistically, elevated TGF-β activity, associated with the persistent presence of HBV in the liver tissue, suppresses(More)
The transcription factor IRF3 is a central regulator of type I interferon (IFN) signaling. The mechanisms underlying deactivation of IRF3 are poorly understood although many studies suggest that IRF3 activity is terminated through degradation after viral infection. Here we report that IRF3 is deactivated via dephosphorylation mediated by the serine and(More)
Pancreatic cancer is one of the most malignant diseases in the world. Interferon regulator factor 2 (IRF-2), an interferon regulatory factor, has been known to act as an oncogene in distinct types of cancer. In this study, we found that the expression of IRF-2 was up-regulated in primary pancreatic cancer samples and associated with tumor size,(More)
Tumor suppressor p53, which is activated by various stress and oncogene activation, is a target for anti-cancer drug development. In this study, by screening panels of protein kinase inhibitors and protein phosphatase inhibitors, we identified 5-Iodotubercidin as a strong p53 activator. 5-Iodotubercidin is purine derivative and is used as an inhibitor for(More)
Aberrant CCN1 expression has been reported to play an important role in the tumor development. However, the pattern and the role of CCN1 in pancreatic cancer remain largely unknown. Therefore, we further deciphered the role CCN1 played in pancreatic cancer. We first evaluated the CCN1 expression in human pancreatic cancer tissues and pancreatic cancer(More)
Osteopetrosis, a disorder of skeletal bone, can cause death during childhood. We previously described a new spontaneous autosomal recessive osteopetrosis mouse mutant, "new toothless" (ntl). In this study, we reported for the first time the identification, cloning and characterization of the coiled-coil domain-containing 154 (CCDC154), a novel gene whose(More)
Splicing factor 3b subunit 4, a critical component of pre-message RNA splicing complex, has been reported to play an important part in the tumorigenesis. However, the expression pattern and biological role of splicing factor 3b subunit 4 in pancreatic cancer have never been investigated. In this study, we found that both the messenger RNA ( p < 0.001) and(More)
