Skeletal abnormalities and extra-skeletal Ossification in mice with restricted Gsα deletion caused by a renin promoter-Cre transgene
Cell and Tissue Research, 2007Co-Authors: Hayo Castrop, Lee S Weinstein, Mona Oppermann, Diane Mizel, Yuning Huang, Robert Faulhaber-walter, Yvonne Weiss, Min Chen, Stephane Germain, Dan RaglandAbstract:We have recently generated a transgenic mouse line (termed hRen-Cre) that expresses Cre-recombinase under the control of a 12.2-kb fragment of the human renin promoter. In the present study, we have crossed hRen-Cre mice with a mouse strain in which exon 1 of the Gnas gene is flanked by loxP sites. Gnas encodes the α-subunit of the stimulatory G protein (Gsα). Our aim has been to generate a mouse model with locally restricted inactivation of Gsα to extend studies of the role of Gsα function in vivo. Mice with local Cre-mediated inactivation of Gsα (rCre-Gsα) are viable and fertile. Their most obvious phenotype consists of marked skeletal malformations of the forelimbs in which computer-tomography scans reveal shortened and fused extremity bones. Extraskeletal Ossifications occur in the subcutis and in skeletal muscles associated with the affected long bones. Plasma calcium, phosphate and parathyroid hormone are normal. Skin histology has demonstrated diffuse mineralization and Ossification associated with the basal cells of hair follicles. This phenotype in part resembles syndromes in humans associated with loss-of-function of Gsα, such as Albright hereditary osteodystrophy and progressive osseous heteroplasia. The renal phenotype of rCre-Gsα mice is inconspicuous. Plasma renin concentration, ambient urine osmolarity, and the glomerular filtration rate of rCre-Gsα mice do not differ from controls. The absence of measurable functional changes in the renin-angiotensin system indicates insufficient Cre expression in juxtaglomerular granular cells in this strain of mice. Nevertheless, the present report reaffirms the importance of Gsα signaling for bone development and the suppression of ectopic Ossification.
