Abstract

The inactivation of the p53 tumor suppressor pathway, which often occurs through mutations in TP53 (encoding tumor protein 53) is a common step in human cancer. However, in melanoma-a highly chemotherapy-resistant disease-TP53 mutations are rare, raising the possibility that this cancer uses alternative ways to overcome p53-mediated tumor suppression. Here we show that Mdm4 p53 binding protein homolog (MDM4), a negative regulator of p53, is upregulated in a substantial proportion (∼65%) of stage I-IV human melanomas and that melanocyte-specific Mdm4 overexpression enhanced tumorigenesis in a mouse model of melanoma induced by the oncogene Nras. MDM4 promotes the survival of human metastatic melanoma by antagonizing p53 proapoptotic function. Notably, inhibition of the MDM4-p53 interaction restored p53 function in melanoma cells, resulting in increased sensitivity to cytotoxic chemotherapy and to inhibitors of the BRAF (V600E) oncogene. Our results identify MDM4 as a key determinant of impaired p53 function in human melanoma and designate MDM4 as a promising target for antimelanoma combination therapy.

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

  • Elevated MDMX mRNA is detected in 65% of retinoblastomas, and the same percentage of cutaneous melanomas overexpress MDMX protein.

    “Elevated levels of levels of MDMX mRNA are detected in 65% of retinoblastomas and the same percentage of cutaneous melanomas overexpress MDMX protein.21,22”
  • Elevated Mdmx levels are observed in many tumors and during tumorigenesis.

    “elevated Mdmx levels are observed in many tumors.3,18–22”
  • Melanoma rarely has TP53 mutations, but about 65% of melanomas have high MDM4 levels.

    “Melanoma is another tumor in which TP53 is rarely mutated, but approximately 65% of these tumors also have high levels of MDM4 (Gembarska, et al., 2012).”

  • MDM4 is overexpressed in many human cancers.

    “As with MDM2, MDM4 is overexpressed in many human cancers (Danovi, et al., 2004; Gembarska, et al., 2012; Han, et al., 2007; Leventaki, et al., 2012; Ramos, et al., 2001; Riemenschneider, et al., 1999; Valentin-Vega, et al., 2007; Wade, et al., 2013).”

  • MDM2 and MDMX are deregulated in many human cancers and act oncogenically mainly by inhibiting p53.

    “The MDM2 and MDMX (also known as HDMX and MDM4) proteins are deregulated in many human cancers and exert their oncogenic activity predominantly by inhibiting the p53 tumour suppressor.”

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.
