The mRNA expression of ARID1A was positively correlated with the expression of baf250a (in OCCC group, rp=0.936, p<0.01; in OEAC group, rp=0.325, p=0.035).
Sixty-seven low grade OECs (35 associated with endometriosis) were stained immunohistochemically for β-catenin, cyclin D1, BAF250a, PTEN, p53, WT1 and the mismatch repair (MMR) proteins MLH1, PMS2, MSH2 and MSH6.
