Patterning of the lateral ganglionic eminence by the Gsh1 and Gsh2 homeobox genes regulates striatal and olfactory bulb histogenesis and the growth of axons through the basal ganglia

Abstract

The function of the Gsh1 and Gsh2 homeobox transcription factors during development of the mouse telencephalon was studied using loss of function mutations. No telencephalic phenotype was observed in Gsh1 mutants, whereas Gsh2 and Gsh1/2 mutants showed progressively more severe defects in development of neurons derived from the lateral ganglionic eminence (LGE). These defects arise from abnormal dorsoventral specification of LGE progenitor cells. Mice lacking both Gsh1 and Gsh2 have severe hypoplasia of the striatum, olfactory tubercle, and interneurons that migrate from the dorsal LGE to the olfactory bulb. In addition, Gsh function is linked to the development of telencephalic dopaminergic neurons. These observations show that Gsh1 and Gsh2 have early roles in defining the identity of LGE progenitor cells. As a result of the basal ganglia defects in the Gsh1/2 mutants, there are pallial heterotopia near the cortical/subcortical limit and defects in the pathfinding of corticofugal and thalamocortical fibers. These findings highlight the developmental interdependence of adjacent telencephalic structures. J. Comp. Neurol. 461:151–165, 2003. © 2003 Wiley‐Liss, Inc.

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.
