Rescue of embryonic lethality in Mdm2-deficient mice by absence of p53

Jones, Stephen N., Roe, Amy E., Donehower, Lawrence A., Bradley, Allan·1995·Nature

Abstract

The Mdm2 proto-oncogene was originally identified as one of several genes contained on a mouse double minute chromosome present in a transformed derivative of 3T3 cells. Overexpression of Mdm2 can immortalize primary cultures of rodent fibroblasts. Human MDM2 is amplified in 30-40% of sarcomas, and is overexpressed in leukaemic cells. The Mdm2 oncoprotein forms a complex with the p53 tumour-suppressor protein and inhibits p53-mediated transregulation of gene expression. Because Mdm2 expression increases in response to p53, Mdm2-p53 binding may autoregulate Mdm2 expression and modulate the activity of p53 in the cell. We have created Mdm2-null and Mdm2/p53-null mice to determine whether Mdm2 possesses developmental functions in addition to the ability to complex with p53, and to investigate the biological role of Mdm2-p53 complex formation in development. Mice deficient for Mdm2 die early in development. In contrast, mice deficient for both Mdm2 and p53 develop normally and are viable. These results suggest that a critical role of Mdm2 in development is the regulation of p53 function.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Loss of Mdm2 causes apoptosis and embryonic lethality at the blastocyst stage, and this phenotype is fully rescued by deleting p53 at the same time.

    “Loss of Mdm2 leads to cell death by apoptosis and embryonic lethality at the blastocyst stage, and this phenotype is completely rescued by concomitant deletion of p53 (Chavez-Reyes, et al., 2003; Jones, et al., 1995; Montes de Oca Luna, et al., 1995).”

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.
