The group’s research activity is focused on:

Study of cellular adaptation to hypoxia and its mimetics in hepatocarcinoma cell lines, cardiomyocytes and inflammatory cells. The study is carried out by analyzing the expression of proteins involved in adaptive processes and their regulation.

 

Currently, the research has its primary focus on:

- Study of intercellular adhesion molecules expression in rat cardiomyocytes, subjected to hypoxic condition or its mimetics.

- Study of transglutaminase expression in cholangiocarcinoma cells with different metastatic capacity: role of resveratrol.
