| Genetic information | Mutant mice deficient for Trp73 exons 2 and 3, which are specific for the TAp73 isoforms, were generated by conventional gene targeting procedures in 129/SvOla embryonic stem cells. Blastocysts were transferred to pseudopregnant C57BL/6J female mice. TAp73 wild-type (+/+; TAp73), heterozygous (+/-; TAp73+/-), and homozygous (-/-; TAp73) littermate mice (129/SvOla × C57BL/6J) were generated by intercrossing TAp73+/- mice (Genes Dev., 2008 Oct 1;22(19):2677-91. doi: 10.1101/gad.1695308). |
| Phenotypic information | Homozygous:A percentage of TAp73-/- mice die during embryogenesis, resulting in an abnormal Mendelian ratio at birth (+/+, 29%; +/-, 52%; -/- 19%). Unable to obtain pups from mating trials involving mating a TAp73-/- male or female with wild-type mice. No oocytes were present in the fallopian tubes of TAp73-/- females 16 h after administration of hCG. The ovulated oocytes were trapped under the bursa and did not progress toward the fallopian tubes. TAp73-/- mice show hippocampal dysgenesis; the lower blade of the dentate gyrus was either completely missing or greatly truncated. 73% of TAp73 mice of a mixed genetic background spontaneously developed malignancies (Fig. 5B,C in Genes Dev., 2008;22(19):2677-91). Lung adenocarcinoma was the most frequent cancer that developed in TAp73 -/-mice, being observed in 32% of all TAp73 mice analysed and representing 44% of all tumours excised from TAp73 -/- mice (Genes Dev., 2008 Oct 1;22(19):2677-91. doi: 10.1101/gad.1695308). Heterozygous:No abnormal phenotype is observed in heterozygous mice (compared to wild-type littermate) |
