DESCRIPTION OF THE OFFER

Ischemia-reperfusion (IR) injury occurs when the blood supply to an organ is interrupted and then restored. IR injury is mainly caused by calcium overload, oxidative stress and mitochondrial dysfuntion. We are studying the molecular and cellular mechanisms that confer ischemia tolerance and protect against IR injury. Currently, we focus on the antioxidant transcription factor Nrf2 (NF-E2-related factor 2), a master regulator of the cellular redox homeostasis, as well as in the PI3K/Akt and ERK1/2 signalling pathways. In this project, we will study the contribution of these pathways to cardioprotection in cultured cardiomyocytes using a combination of biochemistry, molecular biology and cell biology techniques.
