Abstract

We report the characterization of Gsh ‐ 1 , a novel murine homeobox gene. Northern blot analysis revealed a transcript of approximately 2 kb in size present at embryonic days 10.5, 11.5, and 12.5 of development. The cDNA sequence encoded a proline rich motif, a polyalanine tract, and a homeodomain with strong homology to those encoded by the clustered Hox genes. The Gsh ‐ 1 expression pattern was determined for days E8.5 to E13.5 by whole mount and serial section in situ hybridizations. Gsh ‐ 1 transcription was restricted to the central nervous system. Expression is present in the neural tube and hindbrain as two continuous, bilaterally symmetrical stripes within neural epithelial tissue. In the mesencephalon, expression is seen as a band across the most anterior portion. There is also diencephalon expression in the anlagen of the thalamus and the hypothalamus as well as in the optic stalk, optic recess, and the ganglionic eminence. Moreover, through the use of fusion proteins containing the Gsh ‐ 1 homeodomain, we have determined the consensus DNA ninding site of the Gsh ‐ 1 homeoprotein to be GC T / C A / C ATTA G / A . ©1995 Wiley‐Liss, Inc.

  • Vertebrate genes closely related to vnd (Nkx2.1 and Nkx2.2), ind (Gsh1 and Gsh2), and msh (Msx1 and Msx3) are expressed in corresponding ventral, intermediate, and dorsal domains during vertebrate neurogenesis.

    “Vertebrate genes closely related to vnd (Nkx2.1 and Nkx2.2), ind (Gsh1 and Gsh2), and msh (Msx1 and Msx3) are expressed in corresponding ventral, intermediate, and dorsal domains during vertebrate neurogenesis”

    From Dorsoventral patterning in the <i>Drosophila</i> central nervous system: the <i>intermediate neuroblasts defective</i> homeobox gene specifies intermediate column identity (1998) · cites this paper as Valerius et al. 1995

    The In Situ Hybridizations section reports Gsh-1 expression in a restricted mid-ventricular region of the developing mouse neural tube, supporting the intermediate-domain portion of the claim. The Gsh-1 Target DNA Binding Sequence section also reports strong Gsh-1/Gsh-2 homeodomain similarity. Our copy does not establish the proposed relationships to ind, vnd, or msh, or the claimed ventral and dorsal expression patterns of the other listed genes; the passages provide no page numbers. (LLM, conf=0.84)

  • A putative ind ortholog, Gsh1, is expressed in symmetric lateral domains in the mouse neural tube.

    “Consistent with this, a putative ind ortholog, Gsh1, is expressed in symmetric lateral domains in the mouse neural tube (Fig. 7; Valerius et al. 1995).”

    From Dorsoventral patterning in the <i>Drosophila</i> central nervous system: the <i>intermediate neuroblasts defective</i> homeobox gene specifies intermediate column identity (1998) · cites this paper as Valerius et al. 1995

    The In Situ Hybridizations section and Fig. 4 caption report two bilaterally symmetrical stripes of Gsh-1 expression extending along the mouse neural tube; the thoracic section places expression in a restricted mid-ventricular region. The passages do not identify Gsh-1 as a putative ind ortholog, so that part of the claim is not supported by our copy. (LLM, conf=0.86)

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.
