Abstract

This study asks whether the molecular classes of endometrial carcinoma differ in developmental regulatory programmes while keeping association, target-set robustness and cross-cohort transportability as separate claims.

A fetal Müllerian epithelial module and 20 prespecified developmental transcription-factor regulons were evaluated in TCGA-UCEC. Six signals then underwent external evaluation in two independent CPTAC-UCEC strata, together with deletion, purity, molecular-subtype, grade and histology sensitivity analyses.

Two regulons hold their prespecified direction in an independent cohort. None is presented as a validated biomarker.
