Abstract

Introduction: Ischemia/reperfusion injury (I/R) occurs in a number of clinical situations, including hepatic resection (PH). Diabetes mellitus (DM) is an important risk factor for many surgical complications. It is associated with poor prognosis of I/R injury and impairs the liver ability to regenerate. Fibroblast growth factors (FGFs) are a group of proteins that stimulate a wide variety of cell types. Although the importance of liver is widely reported both in production and in action of FGF21, this cytokine has been presented as a stress sign among different tissue. Aim: to identify the production of FGF21 in liver and the relevance of white adipose tissue as source of FGF21 in the context of PH under I/R in diabetic and healthy mice. We will also analyze I/R damage and regeneration in livers submitted PH under I/R and the relationship between liver injury, regeneration and FGF21 levels. Materials and Methods: The analyzes will be performed on samples (liver, plasma and adipose tissue) collected from healthy and diabetic (alloxan, 60 mg / kg, i.v.) mice submitted to PH under I/R. (AU)
