Distinct Roles of Smooth Muscle and Non-muscle Myosin Light Chain-Mediated Smooth Muscle Contraction

open access: yesFrontiers in Physiology, 2020
Both smooth muscle (SM) and non-muscle (NM) myosin II are expressed in hollow organs such as the bladder and uterus, but their respective roles in contraction and corresponding physiological functions remain to be determined.

Changes of smooth muscle contractile filaments in small bowel atresia [PDF]

open access: yes, 2012
AIM: To investigate morphological changes of intestinal smooth muscle contractile fibres in small bowel atresia patients. METHODS: Resected small bowel specimens from small bowel atresia patients (n = 12) were divided into three sections (proximal ...

Fibronectin matrix polymerization regulates smooth muscle cell phenotype through a Rac1 dependent mechanism. [PDF]

open access: yesPLoS ONE, 2014
Smooth muscle cells are maintained in a differentiated state in the vessel wall, but can be modulated to a synthetic phenotype following injury. Smooth muscle phenotypic modulation is thought to play an important role in the pathology of vascular ...

Mechanisms altering airway smooth muscle cell Ca(2+) homeostasis in two asthma models [PDF]

open access: yes, 2008
Background: Asthma is characterized by airway remodeling, altered mucus production and airway smooth muscle cell (ASMC) contraction causing extensive airway narrowing. In particular, alterations of ASMC contractility seem to be of crucial importance. The

Neurogenic Inflammation of Guinea-Pig Bladder

open access: yesMediators of Inflammation, 1994
Capsaicin, substance P, and ovalbumin, instilled into the bladders of naive and ovalbumin (OVA) sensitized guineapigs caused inflammation, as indicated by increased vascular permeability.

Physiology and Pathophysiology of Proteinase-Activated Receptors (PARs): Proteinases as Hormone-Like Signal Messengers: PARs and More

open access: yesJournal of Pharmacological Sciences, 2005
Proteinases like thrombin and trypsin, long known for their ability to activate the coagulation cascade or to act as digestive enzymes for many protein targets, are now recognized as hormone-like regulators of cell function.

Biochemical Properties of a Bushmaster Snake Venom Serine Proteinase (LV-Ka), and Its Kinin Releasing Activity Evaluated in Rat Mesenteric Arterial Rings

open access: yesJournal of Pharmacological Sciences, 2004
A serine proteinase with kallikrein-like activity (LV-Ka) has been purified to homogeneity from bushmaster snake (Lachesis muta muta) venom. Physicochemical studies indicated that LV-Ka is a single chain glycoprotein with a molecular mass (Mr) of 33 kDa ...

Notch2 and Notch3 function together to regulate vascular smooth muscle development. [PDF]

open access: yesPLoS ONE, 2012
Notch signaling has been implicated in the regulation of smooth muscle differentiation, but the precise role of Notch receptors is ill defined. Although Notch3 receptor expression is high in smooth muscle, Notch3 mutant mice are viable and display only ...

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

open access: yes, 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.

Calcium Handling in Airway Smooth Muscle: Mechanisms and Therapeutic Implications

open access: yesCanadian Respiratory Journal, 1998
Calcium plays a central role in the activation of many cellular processes, including the most relevant end-point in airway smooth muscle physiology: contraction.
