Losartan activates sirtuin 1 in rat reduced-size orthotopic liver transplantation

Losartan activates sirtuin 1 in rat reduced-size orthotopic liver transplantation.

AIM To investigate a possible association between losartan and sirtuin 1 (SIRT1) in reduced-size orthotopic liver transplantation (ROLT) in rats. METHODS Livers of male Sprague-Dawley rats (200-250 g) were preserved in University of Wisconsin preservation solution for 1 h at 4 °C prior to ROLT. In an additional group, an antagonist of angiotensin II type 1 receptor (AT1R), losartan, was orall...

Orthotopic Liver Transplantation

A 7-year-old girl with progressive ataxia, spasticity, supranuclear ophthalmoplegia, and sea-blue histiocytes in her bone marrow underwent orthotopic liver transplantation for hepatocellular carcinoma. After an initial period of stabilization, she has shown progression of neurologic symptoms with recurrence of storage material in the transplanted liver. Pediatrics 1986;77:104-106; lipidosis, se...

Orthotopic Liver Transplantation in Rats

Clinical progress in the field of liver transplantation has been largely supported by animal models(1,2). Since the publication of the first orthotopic rat liver transplantation in 1979 by Kamada et al.(3), this model has remained the gold standard despite various proposed alternative techniques(4). Nevertheless, its broader use is limited by its steep learning curve(5). In this video paper,...
