The Selective Rat Toxicant Norbormide Blocks KATP Channels in Smooth Muscle Cells But Not in Insulin-Secreting Cells

Frontiers in Pharmacology, 2019
Norbormide is a toxicant selective for rats to which it induces a widespread vasoconstriction. In a recent paper, we hypothesized a role of ATP-sensitive potassium (KATP) channels in norbormide-induced vasoconstriction.

KATP channels are necessary for glucose-dependent increases in amyloid-β and Alzheimer’s disease–related pathology

JCI Insight, 2023
Elevated blood glucose levels, or hyperglycemia, can increase brain excitability and amyloid-β (Aβ) release, offering a mechanistic link between type 2 diabetes and Alzheimer’s disease (AD).

Pharmacological rescue of trafficking-impaired ATP-sensitive potassium channels

Frontiers in Physiology, 2013
ATP-sensitive potassium (KATP) channels link cell metabolism to membrane excitability and are involved in a wide range of physiological processes including hormone secretion, control of vascular tone, and protection of cardiac and neuronal cells against ...

Expression and function of ATP-dependent potassium channels in zebrafish islet β-cells [PDF]

Royal Society Open Science, 2017
ATP-sensitive potassium channels (KATP channels) are critical nutrient sensors in many mammalian tissues. In the pancreas, KATP channels are essential for coupling glucose metabolism to insulin secretion.

Omega-3 polyunsaturated fatty acid-induced vasodilation in mouse aorta and mesenteric arteries is not mediated by ATP-sensitive potassium channels

Frontiers in Physiology, 2022
There is strong evidence that the omega-3 polyunsaturated fatty acids (n-3 PUFAs) docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) have cardioprotective effects.

Repurposing antimicrobial agents for neuroprotection: Mechanisms, clinical potential, and challenges

Neuroprotection, EarlyView.
Antimicrobial agents exert neuroprotective effects through modulation of interconnected pathways. Tetracyclines, macrolides, antimalarial agents, sulfones, and antiparasitic agents suppress neuroinflammation, oxidative stress, and apoptosis while preserving mitochondrial function and neurotransmission.

Multitarget Regulatory Mechanisms and Research Advances of Plant‐Derived Bioactive Ingredients in Hypertension Prevention and Management

Phytotherapy Research, EarlyView.
Schematic overview of the multi‐target and multi‐pathway mechanisms of PDBI in the prevention and management of hypertension. ABSTRACT Hypertension remains a major global risk factor for cardiovascular diseases, yet current treatments face challenges such as suboptimal blood pressure control and inadequate organ protection.

Photobiomodulation on KATP Channels of Kir6.2-Transfected HEK-293 Cells

International Journal of Photoenergy, 2014
Background and Objective. ATP-sensitive potassium (KATP) channel couples cell metabolism to excitability. To explore role of KATP channels in cellular photobiomodulation, we designed experiment to study effect of low intensity 808 nm laser irradiation on
