RT Journal Article SR Electronic T1 Molecular Prognosis of Endometrial Adenocarcinoma by Expression Patterns of the V-ATPase C1 Subunit JF bioRxiv FD Cold Spring Harbor Laboratory SP 2021.10.05.463029 DO 10.1101/2021.10.05.463029 A1 Abdalla Dib Chacur A1 Juliana Couto-Viera A1 Anna Okorokova Façanha A1 Glenerson Baptista A1 Arnoldo Rocha Façanha YR 2021 UL http://biorxiv.org/content/early/2021/10/06/2021.10.05.463029.abstract AB Comparative analysis of expression patterns of ATP6V1C1 encoding C1 subunit of V-H+-ATPase revealed that molecular alterations correlated with endometrial cancer of better prognosis were grouped with low ATP6V1C1 expression while those correlated with worse prognosis were clustered with high ATP6V1C1 expression levels.Expression patterns of C1 subunit in endometrial adenocarcinoma are associated with molecular malignancy signatures shared by histological subtypes of highest mortality rate suggesting that G3 adenocarcinoma exhibits molecular changes resembling endometrial serous carcinoma.ATP6V1C1 might serve as novel prognostic marker allowing identification of targetable pathways for high-risk endometrial cancer.Competing Interest StatementThe authors have declared no competing interest.
