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.

  • The early defect in heart tube organization corresponds with the displacement of N-cadherin from the cardiomyocyte membrane.

    “Interestingly, the early defect in heart tube organization corresponds with the displacement of N-cadherin from the cardiomyocyte membrane.”

  • Characterization of both lung and cardiac defects in circletail mutants highlighted a role for the PCP pathway in these tissues-in both cases, the distribution of planar polarity protein Vangl2 is disrupted.

    “Characterization of both lung and cardiac defects in circletail mutants also highlighted a role for the PCP pathway in these tissues—in both cases, the distribution of planar polarity protein Vangl2 is disrupted (Phillips et al., 2007; Yates et al., 2013).”

  • Animals homozygous for the circletail allele also have subtle abnormalities in cardiomyocyte organization within the primary heart tube which manifest as gross abnormalities in heart formation at later stages of development.

    “Animals homozygous for the circletail allele also have subtle abnormalities in cardiomyocyte organization within the primary heart tube which manifest as gross abnormalities in heart formation at later stages of development (Phillips et al., 2007).”

  • Scribble and Vangl have collaborative roles in PCP in diverse other mouse tissues, mediating axon guidance in the hindbrain and heart looping and subsequent cardiac development.

    “Subsequently, collaborative roles for Scribble and Vangl in PCP were uncovered in diverse other mouse tissues, mediating axon guidance in the hindbrain (Walsh et al., 2011) and heart looping and subsequent cardiac development (Phillips et al., 2007).”

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.
