Abstract

The AP-1 transcription factors are considered immediate-early response genes and are thought to be involved in a wide range of transcriptional regulatory processes linked to cellular proliferation and differentiation. To study one of the key members of this family, the proto-oncogene c-jun, we have used homologous recombination-mediated gene targeting to produce mice with a c-jun null mutation. c-jun null embryos die at mid-gestation, with an average time of death of 12.5 days postcoitus. Homozygous mutant embryos are indistinguishable from wild-type littermates both grossly and histologically until the time of death. However, primary fibroblasts derived from live heterozygous and homozygous mutant embryos show greatly reduced growth rates in culture. The subnormal mitogenic response of these cells cannot be overcome by the addition of a number of purified mitogens. These studies indicate that although c-jun is not required for cellular proliferation and differentiation up to mid-gestation, it is required for survival past that stage as well as for the mitogenic response of embryonic fibroblasts in culture.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
