Disruption of Planar Cell Polarity Signaling Results in Congenital Heart Defects and Cardiomyopathy Attributable to Early Cardiomyocyte Disorganization

Open access

Abstract

The Drosophila scribble gene regulates apical-basal polarity and is implicated in control of cellular architecture and cell growth control. Mutations in mammalian Scrib ( circletail ; Crc mutant) also result in abnormalities suggestive of roles in planar cell polarity regulation. We show that Crc mutants develop heart malformations and cardiomyopathy attributable to abnormalities in cardiomyocyte organization within the early heart tube. N-Cadherin is lost from the cardiomyocyte cell membrane and cell–cell adhesion is disrupted. This results in abnormalities in heart looping and formation of both the trabeculae and compact myocardium, which ultimately results in cardiac misalignment defects and ventricular noncompaction. Thus, these late abnormalities arise from defects occurring at the earliest stages of heart development. Mislocalization of Vangl2 in Crc/Crc cardiomyocytes suggests Scrib is acting in the planar cell polarity pathway in this tissue. Moreover, double heterozygosity for mutations in both Scrib and Vangl2 can cause cardiac defects similar to those found in homozygous mutants for each gene but without other major defects. We propose that heterozygosity for mutations in different genes in the planar cell polarity pathway may be an important mechanism for congenital heart defects and cardiomyopathy in humans.

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.
