DNA methylation signatures follow preformed chromatin compartments in cardiac myocytes

Nature Communications, 2017
Storage of chromatin in restricted nuclear space requires dense packing while ensuring DNA accessibility. Thus, different layers of chromatin organization and epigenetic control mechanisms exist.

Cardiac hypertrophy is inhibited by a local pool of cAMP regulated by phosphodiesterase 2 [PDF]

, 2015
Rationale: Chronic elevation of 3'-5'-cyclic adenosine monophosphate (cAMP) levels has been associated with cardiac remodelling and cardiac hypertrophy.

Genetically Encoded Biosensors Reveal PKA Hyperphosphorylation on the Myofilaments in Rabbit Heart Failure [PDF]

, 2016
RATIONALE: In heart failure, myofilament proteins display abnormal phosphorylation, which contributes to contractile dysfunction. The mechanisms underlying the dysregulation of protein phosphorylation on myofilaments is not clear.

Unusual localization and translocation of TRPV4 protein in cultured ventricular myocytes of the neonatal rat

European Journal of Histochemistry, 2012
TRPV4 protein forms a Ca2+-permeable channel that is sensitive to osmotic and mechanical stimuli and responds to warm temperatures, and expresses widely in various kinds of tissues.

Ventricular androgenic-anabolic steroid-related remodeling: an immunohistochemical study [PDF]

, 2017
Background: Several fatal cases of bodybuilders, following a myocardial infarction after long exposure to androgenicanabolic steroids (AAS), are reported. In recent years, evidence has emerged of cases of heart failure related to AAS consumption, with no

Microtubule-Mediated Misregulation of Junctophilin-2 Underlies T-Tubule Disruptions and Calcium Mishandling in mdx Mice

JACC: Basic to Translational Science, 2016
Cardiac myocytes from the mdx mouse, the mouse model of Duchenne muscular dystrophy, exhibit t-tubule disarray and increased calcium sparks, but a unifying molecular mechanism has not been elucidated.

Identification and characterization of insulin-like growth factor receptors on adult rat cardiac myocytes: linkage to inositol 1,4,5-trisphosphate formation. [PDF]

, 1992
Cultured cardiac myocytes from adult Sprague-Dawley rats express both insulin-like growth factor-I (IGF-I) receptors and insulin-like growth factor-II/mannose 6-phosphate (IGF-II/Man6P) receptors and respond to IGF-I with a dose-dependent accumulation of

De Novo Human Cardiac Myocytes for Medical Research: Promises and Challenges

Stem Cells International, 2017
The advent of cellular reprogramming technology has revolutionized biomedical research. De novo human cardiac myocytes can now be obtained from direct reprogramming of somatic cells (such as fibroblasts), from induced pluripotent stem cells (iPSCs, which

Pressure mediated hypertrophy and mechanical stretch up-regulate expression of the long form of leptin receptor (ob-Rb) in rat cardiac myocytes

BMC Cell Biology, 2012
Background Hyperleptinemia is known to participate in cardiac hypertrophy and hypertension, but the relationship between pressure overload and leptin is poorly understood. We therefore examined the expression of leptin (ob) and the leptin receptor (ob-R)

The Hippo pathway regulates density-dependent proliferation of iPSC-derived cardiac myocytes

Scientific Reports, 2021
Inducing cardiac myocytes to proliferate is considered a potential therapy to target heart disease, however, modulating cardiac myocyte proliferation has proven to be a technical challenge.
