Abstract

Na+/K+‑ATPase is an ancient enzyme, the role of which is to maintain Na+ and K+ gradients across cell membranes, thus preserving intracellular ion homeostasis. The regulation of Na+/K+‑ATPase is affected by several regulatory factors through a number of pathways, with hormones serving important short‑term and long‑term regulatory functions. Na+/K+‑ATPase can also be degraded through activation of the ubiquitin proteasome and autophagy‑lysosomal pathways, thereby affecting its abundance and enzymatic activity. As regards the regulatory effect of insulin, it has been found to upregulate the relative abundance of Na+/K+‑ATPase and restore the transport efficiency in multiple in vitro and in vivo experiments. Therefore, elucidating the role of insulin in the regulation Na+/K+‑ATPase may help uncover new drug targets for the treatment of related diseases. The aim of the present study was to review the structure and function of Na+/K+‑ATPase and to discuss the possible mechanisms through which it may be regulated by insulin, in order to investigate the possibility of designing new therapies for related diseases.

  • One of the principal mechanisms underlying hypokalemia in THPP is increased activity of the Na+/K+-ATPase.

    “One of the principal mechanisms underlying hypokalemia in THPP is the increased activity of the Na+/K+-ATPase, a transmembrane pump that hydrolyses adenosine triphosphate (ATP) to transport three sodium ions out of the cell and two potassium ions into the cell.”

    From Thyrotoxic Hypokalemic Periodic Paralysis: Pathophysiological Mechanisms (2025) · cites this paper as [28]

    The Introduction (page not available) describes the pump’s ATP-driven transport of three sodium ions out of the cell and two potassium ions in. Section 6, under “Skeletal muscle” (page not available), says increased Na+/K+-ATPase activity reduces extracellular potassium. The review does not identify this as a principal mechanism of hypokalemia in THPP. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
