Since then, he was routinely followed-up. At the age of 19 years, laboratory tests showed abnormalities in liver function parameters, and the patient was diagnosed with PSC. Although treatment with ursodeoxycholic acid improved the abnormalities in serum levels of biliary HIF activation enzymes and no PSC-related symptoms were seen for 13 years, calculous cholecystitis frequently occurred in the patient since the age of 32 years. He developed ICC, which expressed some hepatic progenitor cell markers such as CD133, neural cell adhesion molecule, keratin 7, and keratin 19 at the age of 33 years. ICC was treated by curative partial hepatectomy and adjuvant chemotherapy with gemcitabine.
Eight months later, however, the patient developed multiple metastases in the abdominal lymph nodes and lungs, and died 21 months after the onset of ICC. Here, we report a case of ICC that developed after a 14-year follow-up of a patient with PSC and UC. “
“Aim: Hepatic steatosis accompanied by impaired protein synthesis is often observed in hepatic dysfunction. To assess whether protein synthesis inhibition directly induces hepatic steatosis, we investigated the molecular mechanisms of cycloheximide (CHX)-induced fatty liver mice. Methods: C57/BL6CR mice were i.p. administrated CHX (20 mg/kg) three times every 4 h Selleckchem JQ1 to induce hepatic steatosis. Hepatic lipid secretion, fatty acid oxidation, hepatic lipogenesis and hepatic lipid uptake
were evaluated. Results: Twenty-four hours after the first CHX injection, hepatic lipid levels increased in CHX-treated mice to 1.8-fold of that in controls but returned to normal within 48 h. The hepatic triglyceride (TG) secretion rate decreased significantly to 22% of controls, and the apolipoprotein B (apoB) protein level, but not microsomal TG transfer protein, decreased in CHX-treated mice. The apob gene expression was not significantly different between controls and
CHX-treated mice. On the other hand, plasma free fatty acid and lipogenic protein levels did not increase and plasma β-hydroxybutyrate level remained stable, suggesting that the coordinated balance between fatty acid oxidation, hepatic lipid uptake and lipogenesis was not disrupted in this model. Cellular lipid accumulation and decreased cellular and secreted apoB were also observed in CHX-treated HepG2 cells. Knockdown selleck chemicals llc of apoB in HepG2 cells also resulted in the cellular TG accumulation. Conclusion: We demonstrated that decreased hepatic lipid secretion due to acute apoB reduction is involved in the pathogenesis of CHX-induced liver steatosis. “
“Whether preoperative clinically significant portal hypertension (CSPH) has or not an impact on the outcome of surgery for hepatocellular carcinoma (HCC) in patients with compensated cirrhosis is debated. This systematic review assesses the impact of CSPH on the outcome of HCC in patients with compensated cirrhosis treated with surgery.
