| Genetic information | The primate diphtheria toxin receptor (DTR, or heparin-binding epidermal growth factor-like growth factor - HBEGF) is inserted into the mouse Gja10 (Cx57) locus leading to expression of the DTR in horizontal cells of the retina. Upon flp recombinase-mediated deletion, the DTR is exchanged for the cre recombinase. |
| Phenotypic information | Allows ablation of retinal horizontal cells by systemic application of diphtheria toxin; without toxin administration, mice show the same phenotype as described for Cx57lacZ (EM:01644). |
| Breeding history | The line was backcrossed at least five times to C57BL/6N. As the C57BL/6N background can harbour the Crb1rd8 (crumbs family member 1, retinal degeneration 8) mutation, researchers who want to use this transgenic strain for studying retinal phenotypes should check for the rd8 locus. For future experiments backcrossing to C57BL/6J would be recommended. The primer combination proposed in the paper by Mattapallil et al., 2012 (IOVS, Vol 53, No. 6, 2921-2927) should be useful to eliminate the rd8 mutation. |
