Inhibition of native TRPC6 channel activity by phosphatidylinositol 4,5-bisphosphate in mesenteric artery myocytes [PDF]

open access: yes, 2008
The present work investigates the effect of phosphatidylinositol-4,5-bisphosphate (PIP2) on native TRPC6 channel activity in freshly dispersed rabbit mesenteric artery myocytes using patch clamp recording and co-immunoprecipitation methods.

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

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.

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

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 ...

Kv7 and Kv11 channels in myometrial regulation. [PDF]

open access: yes, 2013
Ion channels play a key role in defining myometrial contractility. Modulation of ion channel populations is proposed to underpin gestational changes in uterine contractility associated with the transition from uterine quiescence to active labour.

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.

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

Endothelins. Myocardial actions of a new class of cytokines [PDF]

open access: yes, 1992
There is growing evidence to support the existence of a dynamic interaction in vivo between cardiac myocytes and adjacent microvascular endothelial cells in the regulation of both cardiac myocyte and possibly endothelial cell phenotype and function ...
