Abstract:
Examination of random insertional mutations in transgenic animals harbouring an abnormal phenotype contributes to the discovery of new genes and/or the understanding of already known genes. Here we describe a transgenic mouse line showing early-onset obesity as consequence of the transgene insertion. Molecular genetic analysis revealed a partial deletion of the leptin receptor (Lepr, Ob-R) gene including the coding sequences downstream of exon 17". This defect prevents the expression of all described membrane-bound isoforms of Ob-R except for isoform Ob-Rc in the homozygous transgenic animals. Thus, this mouse model might be useful for the investigation of the function of the short Ob-R isoforms.
