Research Abstract

The annexin A4 (ANXA4), one of the highly expressed proteins in ovarian clear cell adenocarcinoma (OCCA), which is typically chemo-resistant and poor-prognosis disease, was our research target. Two OCCA cell lines in which ANXA4 expression is suppressed by shRNA were used. Significantly restricted proliferation and increased chemo-sensitivity were recognized in an acidic-ANXA4-expressing cell, whereas decreased invasiveness was detected in a basic-ANXA4-expressing cell.
