Abstract

Mammalian biology adapts to physical activity but the molecular mechanisms sensing the activity remain enigmatic. Recent studies have revealed how Piezo1 protein senses mechanical force to enable vascular development. Here, we address Piezo1 in adult endothelium, the major control site in physical activity. Mice without endothelial Piezo1 lack obvious phenotype but close inspection reveals a specific effect on endothelium-dependent relaxation in mesenteric resistance artery. Strikingly, the Piezo1 is required for elevated blood pressure during whole body physical activity but not blood pressure during inactivity. Piezo1 is responsible for flow-sensitive non-inactivating non-selective cationic channels which depolarize the membrane potential. As fluid flow increases, depolarization increases to activate voltage-gated Ca 2+ channels in the adjacent vascular smooth muscle cells, causing vasoconstriction. Physical performance is compromised in mice which lack endothelial Piezo1 and there is weight loss after sustained activity. The data suggest that Piezo1 channels sense physical activity to advantageously reset vascular control.

  • Piezo1 channels are present in LSECs in both mice and humans, affecting vascular stability, including endothelial cell vasodilation, tension, and blood flow regulation.

    “Recent studies have identified Piezo1 channels in LSECs in both mice and humans,34,43,45,83 which affect vascular stability, including endothelial cell vasodilation, tension, and blood flow regulation.44”

    From Mechanosensitive calcium ion channels Piezo1: A therapeutic target in liver disease (2025) · cites this paper as [34]

    Citation 44 is attached to the vascular-effects clause, not the claim that Piezo1 is present in mouse and human LSECs. The Introduction and Results describe endothelial Piezo1 affecting vascular tone, blood pressure, and the redistribution of blood flow during exercise, particularly through flow-induced vasoconstriction in mouse mesenteric arteries. They do not establish the broader claim about vascular stability or a general Piezo1-mediated vasodilation effect. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Most endothelial cells express Piezo1 in the mRNA and protein forms.

    “Numerous studies have indicated that most endothelial cells express Piezo1 in the mRNA and protein forms.33,34,82,83,84,85,86”

    From Mechanosensitive calcium ion channels Piezo1: A therapeutic target in liver disease (2025) · cites this paper as [34]

    In Results (‘Constitutive and flow-induced Piezo1 in mesenteric artery’; page unavailable), the paper reports native Piezo1 channel activity in cultured endothelial cells and says that activity is common in mesenteric artery endothelial cells. This supports Piezo1 protein being present in the endothelial cells studied, but the passages do not establish mRNA expression or that most endothelial cells generally express Piezo1. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Piezo1 channels are vital for numerous physiological processes, including cell migration and differentiation, cardiovascular development, blood pressure regulation, and immune modulation.

    “In addition to mechanosensation, Piezo1 channels are vital for numerous physiological processes, including cell migration and differentiation,33 cardiovascular development,34 blood pressure regulation,35 and immune modulation.36”
  • Piezo1 expression in liver cells follows a multimodal distribution pattern, with varying degrees of expression in the biliary system, liver sinusoidal microvasculature, portal vein narrow areas, and liver parenchyma.

    “Several studies have demonstrated that Piezo1 expression in cells follows a multimodal distribution pattern, with varying degrees of expression in the biliary system,39 liver sinusoidal microvasculature, portal vein narrow areas,34,43 and liver parenchyma.”

    From Mechanosensitive calcium ion channels Piezo1: A therapeutic target in liver disease (2025) · cites this paper as [34]

    The Methods section describes isolating mouse liver sinusoidal endothelial cells, but does not report Piezo1 expression in them. The Results passages concern mesenteric artery endothelium and liver histology, not a distribution of Piezo1 across the biliary system, portal vein, and liver parenchyma. Searches for those liver structures and a multimodal expression pattern found no supporting passage; page numbers are unavailable in our copy. (LLM, conf=0.72)

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.
