Onset of experimental severe cardiac fibrosis is mediated by overexpression of angiotensin-converting enzyme 2 [PDF]
, 2009 Angiotensin-converting enzyme (ACE) 2 is a recently identified homologue of ACE. There is great interest in the therapeutic benefit for ACE2 overexpression in the heart.

Imaging Calcium Sparks in Cardiac Myocytes [PDF]
, 2010 Calcium ions play fundamental roles in many cellular processes in virtually all type of cells. The use of Ca(2+) sensitive fluorescent indicators has proven to be an indispensable tool for studying the spatio-temporal dynamics of intracellular calcium ([Ca(2+)](i)).

Are physiological oscillations physiological?
The Journal of Physiology, EarlyView., 2023 Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

β-adrenergic-mediated dynamic augmentation of sarcolemmal CaV 1.2 clustering and co-operativity in ventricular myocytes. [PDF]
, 2019 Key pointsPrevailing dogma holds that activation of the β-adrenergic receptor/cAMP/protein kinase A signalling pathway leads to enhanced L-type CaV 1.2 channel activity, resulting in increased Ca2+ influx into ventricular myocytes and a positive ...

Cardiac Myocytes and Mechanosensation
, 2012 Mechanosensation is a fundamental process in biology and may have been developed by the early cells in response to hypo-osmotic stress [1]. With the evolution of different cell types and the appearance of multi-cellular organisms the mechanisms of mechanosensation and the corresponding transmission of signals became more complex and evolved in ...

Mitochondrial membrane potential in cardiac myocytes
Physiological Research, 2002 Mitochondria are involved in cellular functions that transcend the traditional role of these organelles as the energy factory of the cell. Their relative inaccessibility and the difficulties involved in attempts to study them in their natural environment - the cytosol - has delayed much of this understanding and they still have many secrets to yield ...

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Integrating ER and Mitochondrial Proteostasis in the Healthy and Diseased Heart
Frontiers in Cardiovascular Medicine, 2020 The integrity of the proteome in cardiac myocytes is critical for robust heart function. Proteome integrity in all cells is managed by protein homeostasis or proteostasis, which encompasses processes that maintain the balance of protein synthesis ...
