Rosa damascena Miller essential oil relaxes rat trachea via KV channels, KATP channels, and BKCa channels

open access: yes, 2022
Aim/Objective: This study aimed to investigate the effects of Rosa damascena Miller essential oil on rat tracheal smooth muscle contractility and the hypothesis that voltage-gated potassium (KV) channels, ATP-sensitive potassium (KATP) channels, and ...

Cardiovascular Diseases: Exploring Epidemiology, Pathophysiology, Risk Factors, and Medicinal Plant‐Based Therapies: A Narrative Review

open access: yesHealth Science Reports, Volume 9, Issue 9, September 2026.
ABSTRACT Background and Aims Cardiovascular diseases (CVDs) remain the leading cause of global morbidity and mortality, encompassing coronary artery disease, hypertension, heart failure, and cerebrovascular disorders. The global burden of CVD continues to rise, driven by complex interactions among endothelial dysfunction, oxidative stress, inflammation,

Regulation of KATP channel activity

open access: yes, 2021
ATP-sensitive potassium (KATP) channels are present in many tissues, most notably pancreatic islets and cardiac cells, where they couple the metabolic state of a cell to its electrical activity by regulating the flow of K+ across the membrane in response to the intracellular ATP/ADP ratio.

Lactate activation of α-cell KATP channels inhibits glucagon secretion by hyperpolarizing the membrane potential and reducing Ca2+ entry

open access: yesMolecular Metabolism, 2020
Objective: Elevations in pancreatic α-cell intracellular Ca2+ ([Ca2+]i) lead to glucagon (GCG) secretion. Although glucose inhibits GCG secretion, how lactate and pyruvate control α-cell Ca2+ handling is unknown.

Inhibition of NHE1 Overcomes Temozolomide‐Resistance in Glioblastoma via ROS‐AKT/ERK Axis‐Mediated Autophagy Suppression

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 9, September 2026.
NHE1 inhibition via HOE‐642 suppresses autophagy through the ROS‐AKT/ERK axis, reversing temozolomide resistance in glioblastoma by disrupting the autophagy‐apoptosis balance and enhancing TMZ sensitivity in vitro and in vivo. ABSTRACT Glioblastoma (GBM) is the most aggressive primary brain tumor in adults, with temozolomide (TMZ) resistance being a ...

MicroRNA‐Driven Regulation of β‐Cell Function in Type 2 Diabetes: Molecular Mechanisms, Network Insights, and Translational Perspectives

open access: yesActa Physiologica, Volume 242, Issue 9, September 2026.
ABSTRACT MicroRNAs (miRNAs) have emerged as central regulators of pancreatic islet biology, influencing β‐cell development, proliferation, and function. In type 2 diabetes (T2D), both adaptive and maladaptive miRNA responses shape β‐cell compensation and progressive secretory dysfunction.

ATP-Sensitive Potassium Channel Currents in Eccentrically Hypertrophied Cardiac Myocytes of Volume-Overloaded Rats

open access: yesInternational Journal of Cell Biology, 2011
ATP-sensitive potassium channels (KATP) protect the myocardium from hypertrophy induced by pressure-overloading. In this study, we determined the effects of these channels in volume-overloading.

Intra‐Islet Paracrine Regulation of Glucagon Secretion During Hypoglycemia, Euglycemia, and Hyperglycemia

open access: yesAnnals of the New York Academy of Sciences, Volume 1563, Issue 1, September 2026.
Glucagon, a counterregulatory hormone released from pancreatic α‐cells, maintains glucose homeostasis by acting as a protective barrier against hypoglycemia and an amplifier of insulin release when glucose levels rise with feeding. In the body, glucagon secretion is regulated by circulating glucose levels, with elevations in amino acids and via other ...

A Quarter Century of EHD Protein Research: From Endosomal Recycling to Ciliopathies

open access: yesTraffic, Volume 27, Issue 3, September 2026.
Human EHD protein subcellular localization. ABSTRACT Eps15 homology domain‐containing proteins comprise a conserved family of membrane‐remodeling ATPases that regulate endocytic trafficking, membrane fission, receptor recycling, primary ciliogenesis and membrane dynamics across eukaryotes. Since the initial identification of EHD1 and its Caenorhabditis

The distribution and function of the ATP-sensitive potassium channel subunit Kir6.1 in cardiac and skeletal muscle cell lines. [PDF]

open access: yes, 2007
ATP-sensitive potassium channels (KAtp) are present in the plasma membrane of a number of tissues but are also present on endomembranes such as the endoplasmic reticulum (ER) and mitochondria.
