Hox10 and Hox11 Genes Are Required to Globally Pattern the Mammalian Skeleton

Wellik, Deneen M., Capecchi, Mario R.·2003·Science

Abstract

Mice in which all members of the Hox10 or Hox11 paralogous group are disrupted provide evidence that these Hox genes are involved in global patterning of the axial and appendicular skeleton. In the absence of Hox10 function, no lumbar vertebrae are formed. Instead, ribs project from all posterior vertebrae, extending caudally from the last thoracic vertebrae to beyond the sacral region. In the absence of Hox11 function, sacral vertebrae are not formed and instead these vertebrae assume a lumbar identity. The redundancy among these paralogous family members is so great that this global aspect of Hox patterning is not apparent in mice that are mutant for five of the six paralogous alleles.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • PG10 hox genes prevent rib formation, normally precluding ribs on lumbar vertebrae; ectopic expression prevents ribs, and complete loss of function causes ribs almost everywhere.

    “the PG10 hox genes prevent rib formation, normally used to preclude ribs on the lumbar vertebrae; if expressed ectopically no ribs form and in complete loss of function ribs form almost everywhere (Carapuco et al., 2005; Vinagre et al., 2010; Wellik and Capecchi, 2003).”

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.
