Cardiac ventricular Kir6.1 ATP-sensitive potassium channels: an overlooked effector of cardioprotection [PDF]
IntroductionAdenosine triphosphate (ATP)-sensitive potassium (KATP) channels are octameric structures, comprising a pore-forming homotetramer of Kir6.1 or Kir6.2, with 4 accessory sulphonylurea receptor (SUR) subunits.

Functional expression of inwardly rectifying and ATP-sensitive potassium channels in human pulmonary artery smooth muscle and endothelial cells. [PDF]
Abstract figure legend Inwardly rectifying (Kir2) and ATP‐sensitive (KATP) potassium channels are functionally expressed in human pulmonary artery endothelial and smooth muscle cells. The schematic illustrates how Kir2‐ and KATP‐mediated K+ efflux contributes to VM regulation and pulmonary vascular tone.

Gain-of-function mutations in KATP channel subunits compromise colonic tight junction integrity and epithelial homeostasis in murine models of Cantú syndrome [PDF]
IntroductionCantú syndrome (CS) is a rare genetic disorder caused by gain-of-function (GOF) mutations in the KCNJ8 (Kir6.1) or ABCC9 (SUR2) subunits of ATP-sensitive potassium (KATP) channels.

Effect of Type-2 Diabetes Mellitus on the Expression and Function of Smooth Muscle ATP-Sensitive Potassium Channels in Human Internal Mammary Artery Grafts [PDF]
Here we have shown for the first time altered expression of the vascular smooth muscle (VSM) KATP channel subunits in segments of the human internal mammary artery (HIMA) in patients with type-2 diabetes mellitus (T2DM). Functional properties of vascular

Kir6.1, a component of an ATP-sensitive potassium channel, regulates natural killer cell development [PDF]
IntroductionInvolved in immunity and reproduction, natural killer (NK) cells offer opportunities to develop new immunotherapies to treat infections and cancer or to alleviate pregnancy complications. Most current strategies use cytokines or antibodies to

Age-dependent cerebral vasodilation induced by volatile anesthetics is mediated by NG2+ vascular mural cells [PDF]
Anesthesia can influence cerebral blood flow by altering vessel diameter. Using in vivo two-photon imaging, we examined the effects of volatile anesthetics, sevoflurane and isoflurane, on vessel diameter in young and adult mice.

KLF5 Regulation of Exosome-Derived miR-152-3p From Bone Marrow Stem Cells Improves Ventricular Arrhythmia After Myocardial Infarction. [PDF]
Cardiac fibroblasts (CFs) are activated into cardiac myofibroblasts (CMFs) in myocardial infarction (MI) and promote fibrosis, playing a crucial role in deteriorating cardiac function and inducing fatal arrhythmias. Transplantation of bone marrow mesenchymal stem cells (BMSCs) has emerged as a promising therapeutic approach for ischemic heart diseases,
