Early pathohistological changes in dysfunction of arteriovenous fistula for hemodialysis [PDF]

Vojnosanitetski Pregled, 2010
Background. In hemodialysis patients the most common cause of vascular access failure is neointimal hyperplasia of vascular smooth muscle cells at the venous anastomosis of arteriovenous fistulas. Case report.

Incretin‐Based Therapies: A Testable Hypothesis Linking Incretin Signaling, Mitochondrial Redox, and OXPHOS Efficiency

Obesity, EarlyView.
ABSTRACT Objective Incretin‐based obesity therapies (IBTs), especially GLP‐1 receptor agonists (GLP‐1 RAs), effectively treat obesity and improve comorbidities. However, their impact on energy metabolism is unclear. A recent case of acute generalized muscle weakness in a patient with mitochondrial myopathy after tirzepatide exposure raises concerns ...

Evidence For Phosphorylation-Dependent Modulation of BK Channel Activity in Vascular Smooth Muscle (VSM) Myocytes and Resistance Arteries [PDF]

Biophysical Journal, 2016
VSM excitability is regulated by large conductance, calcium-activated K+ (BK) channels. We have previously reported that type I cGMP-dependent protein kinase (cGKI) phosphorylates the BK channel at key serine residues, leading to augmented BK current magnitude. Here, we investigate the cellular mechanisms regulating the temporal pattern (i.e. onset and

Integrative Approaches in Cardiovascular Disease: The Role of Nutraceuticals in Heart Failure, Atrial Fibrillation, and Related Conditions

Phytotherapy Research, EarlyView.
Schematic representation of the shared pathophysiological mechanisms underlying heart failure (HF) and atrial fibrillation (AF), including inflammation, oxidative stress, endothelial dysfunction, and fibrosis. The figure highlights the clinical and mechanistic convergence of conventional pharmacological therapies and selected nutraceuticals in ...

Study of calcium sparks in skeletal and smooth muscle cells in normal and pathological conditions [PDF]

, 2016
mTOR signaling influence a wide range of cellular process including protein synthesis (Iadevaia et al., 2012; Ma and Blenis, 2009; Thoreen et al., 2012), lipids synthesis (Lamming and Sabatini, 2013), transcription (Dibble and Manning, 2013; Vazquez ...

Gentiopicroside Regulates EGFR and Induces Its Lysosomal Degradation to Attenuate Heart Failure

Phytotherapy Research, EarlyView.
GPS attenuates pressure overload‐induced cardiac remodeling by promoting lysosomal degradation of EGFR. TAC‐induced EGFR accumulation activates AKT/ERK1/2 signaling and drives pathological cardiac hypertrophy, fibrosis, apoptosis, oxidative stress, and cardiac dysfunction. GPS promotes lysosome‐dependent EGFR degradation, thereby limiting excessive AKT/

Thapsigargin-resistant thiacalix[4]arene C-1087-sensitive component of the contractile activity in rat myometrium reflects the functioning of plasma membrane calcium pump

Біологічні студії, 2023
Background. According to existing knowledge, thiacalix[4]arene С-1087 is highly capable of inhibiting Са2+-pump (Са2+, Mg2+-АТРase) of the plasma membrane; at the same time it inhibits the functioning of Са2+-pump of the sarcoplasmic reticulum of uterine

Non‐canonical PKG1 regulation in cardiovascular health and disease

British Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

Characterization of the tissue-level Ca2+signals in spontaneously contracting human myometrium [PDF]

, 2012
In the labouring uterus, millions of myocytes forming the complex geometrical structure of myometrium contract in synchrony to increase intrauterine pressure, dilate the cervix and eventually expel the foetus through the birth canal.

Cardiotoxicity of BRAF/MEK inhibitors

British Journal of Pharmacology, EarlyView.
Abstract Rapidly accelerated fibrosarcoma type B/B‐Raf proto‐oncogene, serine/threonine kinase (BRAF) and mitogen‐activated protein kinase (MEK) inhibitors have transformed outcomes in cancer therapy, particularly in melanoma. However, cardiovascular toxicities are increasingly recognized in real‐world clinical practice.
