The use of calcium channel blockers in the treatment of cardiovascular diseases [PDF]

open access: yesArhiv za farmaciju, 2015
Voltage-sensitive calcium channels (L-type) mediate the entry of extracellular calcium into smooth muscle and cardiac myocytes and sinoatrial and atrioventricular nodal cells in response to electrical depolarization.

The Selective Rat Toxicant Norbormide Blocks KATP Channels in Smooth Muscle Cells But Not in Insulin-Secreting Cells

open access: yesFrontiers in Pharmacology, 2019
Norbormide is a toxicant selective for rats to which it induces a widespread vasoconstriction. In a recent paper, we hypothesized a role of ATP-sensitive potassium (KATP) channels in norbormide-induced vasoconstriction.

Calcium currents in isolated rabbit coronary arterial smooth muscle myocytes.

open access: yesThe Journal of Physiology, 1990
1. Calcium inward currents were recorded from relaxed enzymatically isolated smooth muscle cells from the rabbit epicardial left descending coronary artery using a single‐pipette voltage‐clamp technique. Outward K+ currents were blocked with CsCl‐tetraethylammonium‐filled pipette solutions. 2. Relaxed coronary smooth muscle cells had a maximum diameter

Sources and regulation of nitric oxide synthesis in uterus smooth muscle cells [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2019
It was proved that NO synthesis in isolated mitochondria of rat uterus smooth muscle depended on the entry of exogenous Ca2+ to mitochondria (inhibited by 1-10 mM Mg2+ in the absence of ATP and by 10 μM ruthenium red) and was suppressed by calmodulin ...

Effects of polyamines on the muscarinic receptor‐operated cation current in guinea‐pig ileal smooth muscle myocytes [PDF]

open access: yesBritish Journal of Pharmacology, 2004
The effects of extracellular and intracellular polyamines (PAs), spermine and putrescine, on the cation current (mICAT) evoked either by activating muscarinic receptors with carbachol or by intracellularly applied GTPγS (in the absence of carbachol) were studied using patch‐clamp recording techniques in single guinea‐pig ileal myocytes. Extracellular

Nitric oxide mediates stretch-induced Ca2+ release via activation of phosphatidylinositol 3-kinase-Akt pathway in smooth muscle.

open access: yesPLoS ONE, 2008
BackgroundHollow smooth muscle organs such as the bladder undergo significant changes in wall tension associated with filling and distension, with attendant changes in muscle tone.

Myocardial repair with long-term and low-dose administration of a nitric oxide synthesis inhibitor. Myofibroblasts, type III collagen and fibronectin

open access: yesArquivos Brasileiros de Cardiologia, 1999
OBJECTIVE: To study the healing process of the myocardium in hypertensive rats undergoing inhibition of nitric oxide synthesis. METHODS: Two groups of animals were studied: one received L-NAME, 12mg/kg/day, and the other was a control group. The presence

Heteromeric Channels Formed From Alternating Kv7.4 and Kv7.5 α-Subunits Display Biophysical, Regulatory, and Pharmacological Characteristics of Smooth Muscle M-Currents

open access: yesFrontiers in Physiology, 2020
Smooth muscle cells of the vasculature, viscera, and lungs generally express multiple α-subunits of the Kv7 voltage-gated potassium channel family, with increasing evidence that both Kv7.4 and Kv7.5 can conduct “M-currents” that are functionally ...

Calix[4]arene C-99 inhibits myosin ATPase activity and changes the organization of contractile filaments of myometrium [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2015
Calix[4]arenes are cup-like macrocyclic (polyphenolic) compounds, they are regarded as promising molecular “platforms” for the design of new physiologically active compounds.

Piezo1 in Smooth Muscle Cells Is Involved in Hypertension-Dependent Arterial Remodeling

open access: yesCell Reports, 2015
The mechanically activated non-selective cation channel Piezo1 is a determinant of vascular architecture during early development. Piezo1-deficient embryos die at midgestation with disorganized blood vessels.
