Abstract

Background Activating mutations of the BRAF oncogene play a central role in the development of various cancer types, but their role in human adrenocortical tumors is unknown. At variance, activating mutations of another oncogene, CTNNB1, which encodes beta-catenin, have been shown to be common events in both benign and malignant adrenocortical tumors.Aim To investigate the prevalence of BRAF and CTNNB1 activating mutations in sporadic adrenocortical tumors.Materials and methods Tissue samples from 15 adrenocortical carcinomas and 41 adrenocortical adenomas were investigated for the presence of BRAF and CTNNB1 activating mutations by PCR amplification and direct sequencing.Results An advanced invasive non-functioning adrenocortical carcinoma carried a somatic heterozygous BRAF V600E mutation, while 4 functioning and 4 non-functioning adenomas and 3 functioning carcinomas carried different CTNNB1 activating mutations.Conclusions Activating BRAF somatic mutations may be occasionally found in advanced adrenocortical carcinomas, while CTNNB1 activating mutations are early and common events in adrenal tumorigenesis.

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • High-grade ACCs are enriched for mutations of TP53 and/or CTNNB1, and these mutations tend to be mutually exclusive.

    “High-grade ACCs are enriched for mutations of TP53 (14, 140–142) and/or CTNNB1 (143–149), and these mutations tend to be mutually exclusive (reviewed in Ref. 150).”

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.
