The INSL3-LGR8/GREAT ligand-receptor pair in human cryptorchidism.
Testicular descent is a complex multistep embryonic process requiring the interaction between anatomical and hormonal factors. Failure in any of these steps results in cryptorchidism, the most frequent congenital anomaly of the urogenital tract in human males. Evidence for a genetic cause for cryptorchidism is numerous and supported by animal models. In particular, INSL3 and LGR8/GREAT proteins...
متن کاملTargeted disruption of the murine zyxin gene.
Zyxin is an evolutionarily conserved protein that is concentrated at sites of cell adhesion, where it associates with members of the Enabled (Ena)/vasodilator-stimulated phosphoprotein (VASP) family of cytoskeletal regulators and is postulated to play a role in cytoskeletal dynamics and signaling. Zyxin transcripts are detected throughout murine embryonic development, and the protein is widely ...
متن کاملTargeted disruption of the estrogen receptor gene in male mice causes alteration of spermatogenesis and infertility.
The reproductive system of male mice homozygous for a mutation in the estrogen receptor (ER) gene (ER knock-out; ERKO) appears normal at the anatomical level. However, these males are infertile, indicating an essential role for ER-mediated processes in the regulation of male reproduction. Adult ERKO male mice have significantly fewer epididymal sperm than heterozygous or wild-type males. Althou...
متن کاملTargeted disruption of the Kvlqt1 gene causes deafness and gastric hyperplasia in mice.
The KvLQT1 gene encodes a voltage-gated potassium channel. Mutations in KvLQT1 underlie the dominantly transmitted Ward-Romano long QT syndrome, which causes cardiac arrhythmia, and the recessively transmitted Jervell and Lange-Nielsen syndrome, which causes both cardiac arrhythmia and congenital deafness. KvLQT1 is also disrupted by balanced germline chromosomal rearrangements in patients with...
متن کاملAB210. Targeted disruption of the spermatid-specific gene Spata31 causes male infertility
Spata31, a novel testis-specific gene, was first isolated from the testis of a vitamin A-deficient rat model. To gain insight into its physiological function, Spata31-targeted knockout mice were generated by homologous recombination. Spata31-deficient (Spata31(flox/flox) ; Vasa-Cre) male mice exhibited low sperm count and premature shedding of germ cells into the lumen, ultimately causing azoos...
