Application of redox biosensor mouse models to study redox processes in cardiomyocytes
(2019-08-08)Reactive oxygen species (ROS) are highly reactive molecules produced in any biological system. When ROS are produced in higher amounts, they are lethal to cells. Therefore cells possess a tight redox regulation through ... -
Cardiac and fibroblastic properties after HIF-1α stabilization
(2015-06-01)The cellular oxygen sensing prolyl-4-hydroxylase domain proteins (PHDs) are essential regulators of the α-subunit of hypoxia-inducible transcription factors (HIFs) which are known to induce a variety of genes affecting ... -
Mechanisms underlying low flow-low gradient aortic stenosis
(2020-11-09)Aortic stenosis (AS) remains the most common valvular disease in the elderly with an increasing prevalence, owing to the predominance of degenerative etiologies; hence, represents a major public health burden. The majority ... -
Mild production of reactive oxygen species reversibly affects the metabolism and function of the heart
(2023-01-25)Reactive oxygen species (ROS) are molecular oxygen derivatives that are produced as an attribute of aerobic life. The relationship between elevated levels of ROS and heart failure (HF) has been extensively studied. However, ... -
Myofibroblast differentiation in hypoxia: a novel role for ArhGAP29
(2019-05-20)Myofibroblasts are crucial for normal wound healing and tissue remodelling and play an es-sential role in the pathogenesis of ischemic tissue fibrosis. Due to their contractile features, myofibroblasts support wound closure; ... -
Physiology, metabolism and redox mechanisms in chronic cardiac volume overload
(2016-11-04)Chronic haemodynamic stress in the heart, induced by volume or pressure overload, contributes to cardiac dysfunction and heart failure and is associated with several human cardiovascular diseases (e.g. valvular heart ... -
Prolyl-4-hydroxylase domain 3 (PHD3) is a critical terminator for cell survival of macrophages under stress conditions
(2014-07-14)On molecular level, cells sense changes in oxygen availability through the prolyl-4-hydroxylase domain enzymes (PHDs), which in turn regulate the protein stability of the α-subunit of the transcription factor hypoxia-inducible ... -
The oxygen sensor PHD2 affects energy metabolism and cell function in macrophages
(2016-11-08)Macrophages are key players in the innate immune system and contribute significantly to inflammation in ischemic tissues, such as the infarcted heart. During inflammation, macrophages are involved in tissue remodeling, ... -
The role of the oxygen sensors PHD2 and PHD3 in the response of macrophages to ischemia-induced inflammation
(2016-12-12)Ischemic diseases, caused by the occlusion of a supplying blood vessel, result in a severe lack of oxygen and nutrients within the tissue. The ischemic insult triggers an inflammatory response of the innate immune system. ...
