Cholangiocarcinoma (CCA) is one of the most frequent malignant epithelial liver tumors after hepatocellular carcinoma (HCC). Its incidence seems to be increasing worldwide, although risk factors are heterogeneous and differ globally. Although diagnostic and therapeutic medicine have advanced in several countries, tackling this tumor remains a challenge. The(More)
Hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (CCA) are the two most common primary liver malignancies in adult patients. The molecular mechanisms underlying the pathogenesis of HCC and CCA are still poorly understood. Sonic hedgehog (SHH) signaling plays an essential role during mammalian development, i.e., promoting organ growth,(More)
BACKGROUND Cholangiocarcinoma (CC) is the most frequent malignant epithelial tumor of the biliary system. CC has received increasing interest due to its different etiologic factors, invasiveness, and the difficulty of diagnosis at an early stage. The pathogenesis of CC has not been clearly defined, but cohesiveness of tumor cells seems to be a critical(More)
AIMS To assess the expression of Twisted gastrulation (TWSG1) protein, which regulates the activity of bone morphogenetic proteins (BMPs) in the extracellular space in malignant epithelial tumours of the liver. METHODS Thirteen hepatocellular carcinoma (HCC) samples and 12 intrahepatic cholangiocellular carcinoma (CCA) samples were compiled into(More)
Hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) are two major liver malignancies. Although some phenotypic overlap is known, HCC and CCA are usually different with regard to etiology, histology, and prognosis. Gene expression and deacetylase activity of the class III histone deacetylase SIRT1 are up-regulated in cancer cells due to oncogene(More)
