Mechanical stress-induced cardiac hypertrophy: mechanisms and signal transduction pathways.

Cardiac hypertrophy is a well known response to increased hemodynamic load. Mechanical stress is considered to be the trigger inducing a growth response in the overloaded myocardium. Furthermore, mechanical stress induces the release of growth-promoting factors, such as angiotensin II, endothelin-1, and transforming growth factor-beta, which provide a second line of growth induction. In this re...

Signal transduction.

This issue of Breast Disease focuses on the subject of signal transduction and its role in the pathogenesis and progression of human breast cancer. Within the past 10 years, the explosion in our knowledge of these processes has significantly altered our understanding of breast cancer, and resulted in the first receptor-based therapies. This issue examines a variety of relevant signaling pathway...

Differential activation of signal transduction pathways in human hearts with hypertrophy versus advanced heart failure.

BACKGROUND Left ventricular failure is commonly preceded by a period of hypertrophy. Intriguingly, many of the signaling pathways that have been implicated in the regulation of hypertrophy, including the 3 mitogen-activated protein kinases (MAPKs: extracellular signal-regulated kinase, stress-activated protein kinase, and p38), protein phosphatase, calcineurin, and the protein kinase Akt and it...

A requirement for the rac1 GTPase in the signal transduction pathway leading to cardiac myocyte hypertrophy.

We have used adenoviral-mediated gene transfer of a constitutively active (V12rac1) and dominant negative (N17rac1) isoform of rac1 to assess the role of this small GTPase in cardiac myocyte hypertrophy. Expression of V12rac1 in neonatal cardiac myocytes results in sarcomeric reorganization and an increase in cell size that is indistinguishable from ligand-stimulated hypertrophy. In addition, V...

Noisy signal amplification in ultrasensitive signal transduction.

Because intracellular processes are inherently noisy, stochastic reactions process noisy signals in cellular signal transduction. One essential feature of biological signal transduction systems is the amplification of small changes in input signals. However, small random changes in the input signals could also be amplified, and the transduction reaction can also generate noise. Here, we show th...
