| 002323 | 129S4/SvJae-Inhbbtm1Jae/J | Repository-Cryopreserved |
| Homozygous mice are deficient in activin B (betaB:betaB), activin AB (betaA:betaB) and inhibin B (alpha:betaB). Heterozygotes appear normal. Homozygous mutants complete embryonic development and are viable. They are born, however, with open eyes which leads to the development of eye lesions. Homozygous males breed normally but mutant females exhibit a profoundly impaired reproductive ability, characterized by perinatal lethality of their offspring. Mutant females have an increased gestation time and decreased nursing ability that may be the result of impaired milk let-down. There is an upregulation of beta-A activin which may contribute to the phenotype. | ||
| 003808 | B6.129S2(Cg)-Prltm1Hmn/J | Repository-Cryopreserved |
| Mice that are homozygous for the null Prl allele are viable, normal in size and do not display any gross physical or behavioral abnormalities. Homozygous null females have an irregular estrous cycle and are completely infertile. Homozygous null males and heterozygous females exhibit no fertility problems. The targeted insertion of a neomycin resistance gene into exon 4 results in a truncated Prl transcript that produces an 11 kDa prolactin protein that lacks any detectable bioactivity. Mammary gland development is marked by an absence of terminal or lateral lobulation. The disruption of the prolactin gene appears to have no effects on the hematopoietic system. | ||
