The degree of peritoneal dissemination and chemotherapy-resistant tumors is related to the prognosis in patients with advanced-stage ovarian cancer. The epithelial-mesenchymal-transition (EMT) is a multifaceted pathological program that endows cancer cells with the ability to invade and disseminate. CD24 is frequently overexpressed in various human cancers and is correlated with a poor prognosis. We herein examined the functions of CD24 in human ovarian cancer cell lines and evaluated how it contributes to the molecular mechanism underlying the regeneration of cancer stem-like cells (CSCs) through the EMT mechanism in ovarian carcinoma...

Recent studies demonstrated that Protease-activated receptor-2 (PAR-2) correlates with tumor progression in various tissues. On the other hand, oxidative stress arising from endometriosis has been considered a cause of carcinogenesis in ovarian clear cell carcinoma (OCCC). We previously demonstrated that oxidative stress upregulates PAR-2 expression, and we conducted the present study to investigate the PAR-2 expression and its relation to clinicopathological factors and oxidative stress in OCCC. We performed an immunohistochemical evaluation in 95 cases of OCCC...

Angiosperms distinguish themselves from gymnosperms by their ovules that are enclosed before pollination. However, how the ovules get enclosed in angiosperms remains a mystery, especially for Magnoliaceae. The only key to this mystery is finding a series of carpels transitional from fully closed with enclosed ovules to open with naked ovules. We use routine paraffin section technology, LM, SEM to document the morphology and anatomy of carpel variation in Michelia figo (Magnoliaceae). A series of carpel variations within a single flower of Michelia figo (Magnoliaceae) are documented, in which the ovules are exposed in atypical carpels...

PURPOSE: Endometrial cancer can be divided into two types: endometrioid Type 1 (G1, G2) has a hormonal driven etiology, while Type 2 is more aggressive (G3 endometrioid, clear cell and serous cancer type) and estrogen independent. We noticed an increase of more aggressive G3 endometrioid endometrial adenocarcinomas. This observation is of relevance for daily clinical practice because therapy depends on the histopathological grading and myometrial invasion. G3 cancers or myometrial invasion of more than 50% should be hysterectomized including bilateral adnexectomy with pelvine and paraaortal lymphadenectomy...

BACKGROUND: Assuming that tumor cell dissemination requires a shift to a mesenchymal phenotype, we analyzed the incidence of epithelial-to-mesenchymal-transition (EMT)-like circulating tumor cells (CTCs) in ovarian cancer patients and inquired, how their molecular phenotypes respond to platinum-based chemotherapy and influence outcome. RESULTS: Before surgery, overall detection rate for epithelial CTCs was 18%. EMT-like CTCs were more frequently observed (30%) and were mutually exclusive to epithelial CTCs in the majority of patients (82%)...

Cervical cancer is the second most common gynecological cancer worldwide and remains as one of the leading causes of cancer-related death among women. Despite great progress in the treatment of cervical cancer, the 5-year overall survival rate for patients with this disease remains unsatisfactory. Over the past decade, an increasing number of studies indicate a central role for microRNAs in the initiation and progression of cervical cancer. microRNA‑329-3p (miR-329-3p) has been studied in many types of human cancer; however, the expression level, biological role and the underlying mechanism of miR-329-3p in cervical cancer has not yet been investigated...
