Cardiac fibroblast phenotype regulation in engineered connective tissues with a special focus on ER adaptation and stress
(2023-03-23)Cardiovascular diseases cause adverse myocardial remodeling due to cardiomyocyte loss and modifications to the extracellular matrix (ECM), which can ultimately lead to contractile dysfunction and pathological cardiac ... -
Mechanical regulation of cardiac fibroblasts.
(2021-08-09)Cardiac fibrosis progressively contributes to heart failure (HF). Yet, its complex nature still lacks a more comprehensive understanding. One main hurdle is the lack of representative human models providing insights into ... -
The role of Ca2+ influx mechanisms in the regulation of human cardiac fibroblasts in 2D- and 3D- culture models
(2021-06-24)Cardiac fibrosis is a serious health problem commonly associated with cardiovascular diseases and remains an increasing health burden around the globe. The development of cardiac fibrosis involves the activation and ... -
Analysis of the GPCR-induced RhoA signaling in healthy and diseased adult cardiomyocytes
(2019-04-10)Background: The aim of the presented thesis was to analyze the activation of the monomeric G protein RhoA in adult cardiomyocytes and further to unravel the role of the guanine nucleotide exchange factor p63RhoGEF in this ... -
Redox regulation of protein phosphatase-1 and ER stress regulation of connective tissue growth factor in cardiomyocytes
(2017-06-28)Heart failure is one of the most common causes for morbidity and hospitalization in the western civilization. The prognosis is still poor and new therapies are needed. For decades, variations in phosphorylation and redox ... -
RhoGTPases and their relevance for the afterload-dependent myocardial fibrosis
(2016-12-06)The guanine exchange factor p63RhoGEF was identified as a specific activator of the RhoGTPase RhoA and its transcript was found to be abundant in brain and heart tissue. Amongst cardiac cells, the highest expression of ... -
Modulation of Cardiac Fibroblast to Myofibroblast Transition by Rho-Associated Kinases ROCK1 and ROCK2
(2016-10-25)Rho-associated kinases ROCK1 and ROCK2 are serine/threonine kinases that are downstream targets of the small GTPases RhoA, RhoB, and RhoC. They play a critical role in the pathogenesis of myocardial fibrosis; however, their ... -
Role of Secretory Processes in Cardiac Fibroblasts for Heart Failure Development and Progression
(2014-11-27)Cardiac fibroblasts play a major role in fibrogenesis associated with heart failure, since they produce ECM components and secrete important fibrosis-associated mediators, such as connective tissue growth factor (CTGF). ...
