Ionic basis of a differential effect of adenosine on refractoriness in rabbit AV nodal and atrial isolated myocytes [PDF]

, 1999
Methods: The whole cell patch clamp technique was used to record action potentials and ion currents in AV nodal and left atrial myocytes isolated enzymatically from rabbit hearts.

Androgen Effects on the Adrenergic System of the Vascular, Airway, and Cardiac Myocytes and Their Relevance in Pathological Processes

International Journal of Endocrinology, 2020
Introduction. Androgen signaling comprises nongenomic and genomic pathways. Nongenomic actions are not related to the binding of the androgen receptor (AR) and occur rapidly. The genomic effects implicate the binding to a cytosolic AR, leading to protein

Electrochemical potential of the inner mitochondrial membrane and Ca(2+) homeostasis of myometrium cells [PDF]

The Ukrainian Biochemical Journal, 2015
We demonstrated using Ca2+-sensitive fluorescent probe, mitochondria binding dyes, and confocal laser scanning microscopy, that elimination of electrochemical potential of uterus myocytes’ inner mitochondrial membrane by a protonophore carbonyl cyanide m-

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

The FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

Paracrine Effects of FGF23 on the Heart

Frontiers in Endocrinology, 2018
Fibroblast growth factor (FGF) 23 is a phosphaturic hormone primarily secreted by osteocytes to maintain phosphate and mineral homeostasis. In patients with and without chronic kidney disease, enhanced circulating FGF23 levels associate with pathologic ...

High‐resolution spatial transcriptomic atlas of mouse soleus muscle: Unveiling single cell and subcellular heterogeneity in health and denervation

The FEBS Journal, EarlyView.
Seq‐Scope maps skeletal muscle transcriptomes at high spatial resolution while preserving histological context, revealing distinct responses of myofibers, neuromuscular junctions, and stromal cells to denervation. This spatial view uncovers fiber type‐specific and localized remodeling across intact muscle tissue.

Enhancement of K+ conductance improves in vitro the contraction force of skeletal muscle in hypokalemic periodic paralysis [PDF]

, 1990
An abnormal ratio between Na+ and K+ conductances seems to be the cause for the depolarization and paralysis of skeletal muscle in primary hypokalemic periodic paralysis.

A key role for STIM1 in store operated calcium channel activation in airway smooth muscle

Respiratory Research, 2006
Background Control of cytosolic calcium plays a key role in airway myocyte function. Changes in intracellular Ca2+ stores can modulate contractile responses, modulate proliferation and regulate synthetic activity.

The ciliary neurotrophic factor induces Stat3 phosphorylation in distinctive cytotypes of organs involved in body metabolism: An immunohistochemical study

Journal of Anatomy, EarlyView.
p‐STAT3‐positive cells in metabolically relevant peripheral organs and tissues from mice administered with recombinant CNTF (0.3 mg/kg). Abstract Administration of ciliary neurotrophic factor (CNTF) reduces food intake and body weight in both humans and experimental animals, where it also ameliorates hyperglycemia, hyperinsulinemia, and dyslipidemia ...

Ablation of smooth muscle myosin heavy chain SM2 increases smooth muscle contractility and results in postnatal death in mice [PDF]

, 2008
The smooth muscle myosin heavy chains (SMHC) are motor proteins powering smooth muscle contraction. Alternate splicing of SHMC gene at the C-terminus produces SM1, and SM2 myosin isoforms; SM2 (200 kDa) contains a unique 9-amino-acid sequence at the ...
