BACKGROUND Liver cirrhosis is a diffuse hepatic fibrosis, and nodule formation. The transforming growth factor-beta 1 (TGF-beta 1) and interleukin-10 (IL-10) are very important cytokines in hepatic fibrogenesis. The aim of this study was to examine the relationship between the changes of the serum cytokines and morphological changes following common bile duct ligation in experimental rats. ME...

We recently identified HSulf-1 as a down-regulated gene in ovarian carcinomas. Our previous analysis indicated that HSulf-1 inactivation in ovarian cancers is partly mediated by loss of heterozygosity and epigenetic silencing. Here, we show that variant hepatic nuclear factor 1 (vHNF1), encoded by transcription factor 2 gene (TCF2, HNF1beta), negatively regulates HSulf-1 expression in ovarian c...

Activation of hepatic stellate cells (HSC), a key event in liver fibrosis, is caused by diminished adipogenic transcription. This study investigated whether Wnt signaling contributes to "antiadipogenic" activation of HSC and liver fibrogenesis. Culture-activated HSC from normal rats and HSC from cholestatic rat livers were examined for expression of Wnt, Frizzled (Fz) receptors, and coreceptors...

Hepatocyte nuclear factor 1 was identified as the transcription factor binding to a 20 bp (®150 to ®131) region of the gene for human dipeptidyl peptidase IV, which has been shown to be important for the expression of dipeptidyl peptidase IV in the human intestinal and hepatic epithelial cell lines Caco-2 and HepG2. Functional analysis of the hepatocyte nuclear factor 1 site was performed with ...

background: bone marrow transplantation is a good therapeutic modality for beta thalassemia. liver complications is one of the major causes of morbidity and mortality following bmt. determination of the factors of liver injury leads to earlier diagnosis after bmt and improves prognosis. materials and methods: we studied 113 major beta thalassemic patients who have been transplanted from 1990- 2...

HNF1β is expressed exclusively in ovarian clear cell carcinoma (OCCC) and not in other ovarian cancers, regarded as a hallmark of this tumor. This implies its central role in the unique character of OCCC, including resistance to chemotherapy, but its exact role and influence in cancer biology or the molecular bases of its function are largely unknown. Using comprehensive metabolome analysis of ...

Triptolide (TP), the main bioactive component of Tripterygium wilfordii Hook F, can cause severe hepatotoxicity. Isoliquiritigenin (ISL) has been reported to be able to protect against TP-induced liver injury, but the mechanisms are not fully elucidated. This study aims to explore the role of nuclear transcription factor E2-related factor 2 (Nrf2) and hepatic transporters in TP-induced hepatoto...
