MGMT methylation at all four cytosine-guanine dinucleotide sites examined was detected in only 2/81 (2%) specimens, consisting of a high-grade serous carcinoma with high frequency of methylation, and a breast carcinoma with low methylation frequency.
A comparison of miRNA expression in HGSCs and OCCCs identified five miRNAs (miR-132, miR-9, miR-126, miR-34a, and miR-21), with OCCCs demonstrating a statistically higher expression.
Accordingly, we found that the ectopic expression of <i>miR-34a</i> significantly reduced tumor proliferation and invasion through downregulation of IL-6R expression, suggesting that reduced <i>miR-34a</i> expression might play an important role in the malignant potential of HGSC through upregulation of the IL-6R/STAT3 signaling pathway.
Analyses of Rb pathway mechanistic differences among these groups revealed frequent RB1 genomic alterations such as RB1 allelic loss and/or large spanning deletions (83%) in the p16 homo/RB1- subgroups, also indicating that RB1 deletions are frequent in high-grade serous carcinoma.

Because the putative precursors of the other p53 immunophenotypical HGSC are not proposed, we presume γ-H2AX-expressing cells without p53 overexpression may be a potent candidate of null-type TP53-mutated tubal cells, which are named "γ-H2AX responsive foci."
Both frequency of LEF1 expression and β-catenin nuclear expression correlated with the worst 5-year patient survival, supporting important role of both proteins in high-grade serous carcinoma.
