Heterologous Expression of the Piezo1-ASIC1 Chimera Induces Mechanosensitive Currents with Properties Distinct from Piezo1 [PDF]

Neuron, 2017
Piezo1 represents a prototype of the mammalian mechanosensitive cation channel, but its molecular mechanism remains elusive. In a recent study, we showed that C-terminal region, which contains the last two TMs, of 2189-2547 of Piezo1 forms the bona fide pore module, and systematically identified the pore-lining helix and key pore-property-determining ...

High Diagnosis Rate for Nonimmune Hydrops Fetalis With Prenatal Clinical Genome: Expanded Results From the Hydrops‐Yielding Diagnostic Results of Prenatal Sequencing (HYDROPS) Study

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nonimmune hydrops fetalis (NIHF) is characterized by abnormal fluid accumulation in ≥ 2 fetal compartments and may be genetic. The incremental diagnostic yield of prenatal exome sequencing (ES) for NIHF following a negative standard workup was previously explored on 22 cases.

Piezo1 Upregulation in Monocyte‐Derived Macrophages Impairs Post‐Myocardial Infarction Cardiac Repair via Defective Efferocytosis and Enhanced Ferroptosis

Advanced Science
The regulation of macrophage function, particularly that of monocyte‐derived macrophages (MoMs), by mechanical forces during myocardial infarction (MI) remains poorly understood.

Piezo1‐Mediated Mechanotransduction Contributes to Disturbed Flow‐Induced Atherosclerotic Endothelial Inflammation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Disturbed flow generates oscillatory shear stress (OSS), which in turn leads to endothelial inflammation and atherosclerosis. Piezo1, a biomechanical force sensor, plays a crucial role in the cardiovascular system.

Comparison of rat hypertrophic scar models: Caudal tension model with superior pathological consistency

Animal Models and Experimental Medicine, EarlyView.
This study compared hypertrophic scar (HS) formation in SD rats at ear, back, and tail sites with or without mechanical tension. The ear model healed spontaneously by day 30. Dorsal full‐thickness excision (1 × 8 cm) produced moderate HS. In contrast, the tail tension model showed the greatest scar thickness, fibroblast density, collagen deposition ...

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

The Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Mechanosensitive Piezo1 channels mediate renal fibrosis

JCI Insight, 2022
Kidney fibrosis is the final common pathway of progressive kidney diseases, the underlying mechanisms of which are not fully understood. The purpose of the current study is to investigate a role of Piezo1, a mechanosensitive nonselective cation channel ...

Piezo1 Activation Rescues Anabolic Response to Mechanical Loading in Aged Bone via Connexin 43 Hemichannels. [PDF]

Aging Cell
Yoda1‐induced Piezo1 activation enhances Piezo1‐Cx43 interaction upon mechanical stimulation, triggering PI3K‐Akt signaling to drive Cx43 phosphorylation and hemichannel opening. These events elevate PGE2 release, suppress SOST expression in senescent osteocytes, and ultimately enhance bone anabolism on the endosteal surface.
