Molecular Prognosis of Endometrial Adenocarcinoma by Expression Patterns of the V-ATPase C1 Subunit

O_LIComparative 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. C_LIO_LIExpression 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. C_LIO_LIATP6V1C1 might serve as novel prognostic marker allowing identification of targetable pathways for high-risk endometrial cancer. C_LI
