Role of Ryanodine Type 2 Receptors in Elementary Ca2+ Signaling in Arteries and Vascular Adaptive Responses

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Hypertension is the major risk factor for cardiovascular disease, the most common cause of death worldwide. Resistance arteries are capable of adapting their diameter independently in response to pressure and flow‐associated shear stress ...

Functional and autoradiographic evidence for endothelin 1 receptors on human and rat cardiac myocytes. Comparison with single smooth muscle cells. [PDF]

Circulation Research, 1990
This study aimed to determine whether receptors for endothelin were present on the cardiac myocyte as well as on vascular smooth muscle cells. Low- and high-resolution autoradiography was performed using 125I-endothelin 1 on intact rat myocardium and samples of human ventricle obtained from explanted hearts at the time of transplant.

Understanding extracellular vesicles in antiaging

Periodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Cell cultures of human ciliary muscle: growth, ultrastructural and immunocytochemical characteristics [PDF]

, 1991
Primary ciliary muscle cell cultures derived from human donors (16-91 years) were established and characterized by comparing them with ciliary muscle in tissue sections using immunocytochemical and ultrastructural methods.

Expression and function of calcium-activated potassium channels following in-stent restenosis in a porcine coronary artery model

Journal of Advanced Research, 2012
In-stent restenosis (ISR) occurs due to proliferation and migration of smooth muscle cells from media to intima resulting in re-narrowing of the vessel lumen.

Clearance of p16‐positive cardiac cells improves age‐related cardiac remodeling in mice

Experimental Physiology, EarlyView.
Abstract Senescent cells are characterized by expression of markers like p16 and secretion of profibrotic and proinflammatory factors. The role of cellular senescence in age‐related cardiac remodeling and dysfunction is incompletely understood. This study aimed to: (i) evaluate the effect of p16‐ positive cell clearance on cardiac function and ...

Role of cation gradients in hypercontracture of myocytes during simulated ischemia and reperfusion [PDF]

, 1993
We examined the relationship between transsarcolemmal cation gradients and hypercontracture of cardiac myocytes in ischemia and reperfusion using adult rat ventricular myocytes superfused with buffer mimicking normal or ischemic extracellular fluid ...

Tumor Necrosis Factor Alpha Inhibits L-Type Ca2+ Channels in Sensitized Guinea Pig Airway Smooth Muscle through ERK 1/2 Pathway

Mediators of Inflammation, 2016
Tumor necrosis factor alpha (TNF-α) is a potent proinflammatory cytokine that plays a significant role in the pathogenesis of asthma by inducing hyperresponsiveness and airway remodeling. TNF-α diminishes the L-type voltage dependent Ca2+ channel (L-VDCC)

Putting the brakes on muscle growth: Myostatin as regulator of disuse atrophy

Experimental Physiology, EarlyView.
Abstract Skeletal muscle is a highly plastic tissue that rapidly adapts to changes in mechanical loading and metabolic activity. Periods of inactivity, including bed rest, limb immobilization or microgravity, induce a pronounced loss of muscle mass and function.
