Forkhead box O proteins have critical roles in a number of cellular processes, including apoptosis. Acetylation and phosphorylation of forkhead box O proteins are posttranslational modifications that attenuate their transcriptional activity. As supracervical fetal membranes are characterized by increased cell death, the aim of this study was to compare the expression of forkhead box O1, acetylated-forkhead box O1, and Ser-256 phosphorylated forkhead box O1 at supracervical and distal site fetal membrane. Fetal membranes overlying the cervix were identified in situ in women undergoing term elective Caesarean section. Immunohistochemistry (n = 7) was used to analyze the protein expression of f..View full abstract
