Arterial smooth muscle cell PKD2 (TRPP1) channels regulate systemic blood pressure

open access: yeseLife, 2018
Systemic blood pressure is determined, in part, by arterial smooth muscle cells (myocytes). Several Transient Receptor Potential (TRP) channels are proposed to be expressed in arterial myocytes, but it is unclear if these proteins control physiological ...

Divergent differentiation paths in airway smooth muscle culture: induction of functionally contractile myocytes [PDF]

open access: yesAmerican Journal of Physiology-Lung Cellular and Molecular Physiology, 1999
We tested the hypothesis that prolonged serum deprivation would allow a subset of cultured airway myocytes to reacquire the abundant contractile protein content, marked shortening capacity, and elongated morphology characteristic of contractile cells within intact tissue. Passage 1 or 2 canine tracheal smooth muscle (SM) cells were grown to confluence,

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

LIM-only protein, CRP2, switched on smooth muscle gene activity in adult cardiac myocytes [PDF]

open access: yesProceedings of the National Academy of Sciences, 2007
Smooth muscle α-actin gene activity appears in promyocardial cells well before cardiac myocyte differentiation and is down-regulated during the onset of rhythmic contractility and cardiac morphogenesis. The levels of LIM-only CRP2 correlated well with smooth muscle gene activity. Cardiomyocyte-specific expression of CRP2 in transgenic mice

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

open access: yesCirculation 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.

Hypotension due to Kir6.1 gain‐of‐function in vascular smooth muscle [PDF]

open access: yesJournal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2013
BACKGROUND: K(ATP) channels, assembled from pore‐forming (Kir6.1 or Kir6.2) and regulatory (SUR1 or SUR2) subunits, link metabolism to excitability. Loss of Kir6.2 results in hypoglycemia and hyperinsulinemia, whereas loss of Kir6.1 causes Prinzmetal ...

TMEM16A channel upregulation in arterial smooth muscle cells produces vasoconstriction during diabetes.

open access: yesAmerican Journal of Physiology. Heart and Circulatory Physiology, 2021
The pathological involvement of anion channels in vascular dysfunction that occurs during type 2 diabetes (T2D) is unclear. Here, we tested the hypothesis that TMEM16A, a calcium (Ca2+)-activated chloride (Cl-) channel, contributes to modifications in ...

Immunocytochemical characteristics of submucosal uterine myomas [PDF]

open access: yesVojnosanitetski Pregled, 2010
Background/Aim. Myomas of the uterus, the most common benign tumors, have been studied for decades from the aspects of different basic and clinical disciplines. Despite this fact, their pathogenesis is still poorly understood.

Key role for Kv11.1 (ether‐a‐go‐go related gene) channels in rat bladder contractility

open access: yesPhysiological Reports, 2023
In addition, to their established role in cardiac myocytes and neurons, ion channels encoded by ether‐a‐go‐go‐related genes (ERG1‐3 or kcnh2,3 and 6) (kcnh2) are functionally relevant in phasic smooth muscle.

Insights into Activation Mechanisms of Store-Operated TRPC1 Channels in Vascular Smooth Muscle. [PDF]

open access: yes, 2020
In vascular smooth muscle cells (VMSCs), the stimulation of store-operated channels (SOCs) mediate Ca2+ influx pathways which regulate important cellular functions including contraction, proliferation, migration, and growth that are associated with the ...
