However, gene expression breadth and noise can potentially counteract the effect of masking on the rate at which ...

This family is characterized by direct repeats, varying in size from 21 to 37 bp, interspaced by similar ...

... We therefore concluded these mutants represented mutations in the hedgehog gene, and renamed these alleles as hhFS1, hhMM2, and hhRM2. We next mapped each of the mutations on the third chromosome by looking for genetic linkage between the enhancement of our atonal loss-offunction eye phenotype, and ...

Site-specific recombinase technology



Nearly every human gene has a counterpart in the mouse (regardless of the fact that a minor set of orthologues had to follow species specific selection routes). This made the mouse the major model for elucidating the ways in which our genetic material encodes information. In the late 1980s gene targeting in murine embryonic stem (ES-)cells enabled the transmission of mutations into the mouse germ line and emerged as a novel option to study the genetic basis of regulatory networks as they exist in the genome. Still, classical gene targeting proved to be limited in several ways as gene functions became irreversibly destroyed by the marker gene that had to be introduced for selecting recombinant ES cells. These early steps led to animals in which the mutation was present in all cells of the body from the beginning leading to complex phenotypes and/or early lethality. There was a clear need for methods to restrict these mutations to specific points in development and specific cell types. This dream became reality when groups in the USA were able to introduce bacteriophage and yeast-derived site-specific recombination (SSR-) systems into mammalian cells as well as into the mouse
