Loss of E-cadherin triggers peritoneal dissemination, leading to an adverse prognosis for most patients with epithelial ovarian carcinoma (EOC). Because TWIST mainly regulates the epithelial-to-mesenchymal transition and is one of the E-cadherin repressors, we investigated the possibility that TWIST expression affects peritoneal metastasis of EOC using(More)
The incidence of lymph node metastasis by endometrial carcinoma (EMCA) increases with the depth of myometrial invasion, and this depth of invasion has been found to have a major impact on the outcome. In the present study, we assessed the effect of tumor–stromal interactions on the invasive behavior of EMCA cells and examined the involvement of(More)
OBJECTIVE Epithelial-mesenchymal transition (EMT) is a process whereby cells acquire molecular alterations that facilitate cell motility and invasion. In this study, we hypothesized that ionizing irradiation would cause endometrial carcinoma cells (HEC1A) to undergo an increase of motility related to EMT. METHODS We investigated the effect of ionizing(More)
Radiotherapy can be used to treat all stages of cervical cancer. For improving local control via radiotherapy, it is important to use additional antitumor agents. Aminopeptidase N (APN)/CD13, a 150-kDa metalloproteinase, is a multifunctional cell surface aminopeptidase with ubiquitous expression. Recent studies have suggested that APN/CD13 plays an(More)
Ret finger protein (RFP) is a nuclear protein with transcriptional repressive activity that is highly expressed in a variety of human and rodent tumor cell lines. We examined the expression of RFP in human endometrial cancer and assessed its clinical significance. Formalin-fixed, paraffin-embedded sections from endometrial cancer tissues were immunostained(More)
