Forkhead box (FOX) A1 is a member of the FOX family of transcription factors, which serve a function in numerous types of tumor. The present study assessed the potential role of FOXA1 in human epithelial ovarian carcinoma (EOC). Total RNA was isolated from 16 fresh-frozen EOC tumors with paired corresponding non-malignant ovarian epithelium tissues, and FOXA1 expression was analyzed using reverse transcription-quantitative polymerase chain reaction. Immunohistochemical analysis was performed to evaluate FOXA1 expression in 110 epithelial ovarian carcinoma tissue specimens (including 80 serous papillary adenocarcinoma, 9 clear cell carcinoma, 12 endometrioid adenocarcinoma, 5 mucinous carcinoma and 4 transitional cell carcinoma specimens), 24 benign ovarian tumor surface epithelium tissues and 10 normal ovarian tissue samples...

Endometriosis and adenomyosis are histologically defined. The frequency of endometriosis cannot be precisely estimated in the general population. Endometriosis is considered a disease when it causes pain and/or infertility. Endometriosis is a heterogeneous disease with three well-recognized subtypes that are often associated with each other: superficial endometriosis (SUP), ovarian endometrioma (OMA), and deep infiltrating endometriosis (DIE). DIE is frequently multifocal and mainly affects the following structures: the uterosacral ligaments, the posterior vaginal cul-de-sac, the bladder, the ureters, and the digestive tract (rectum, recto-sigmoid junction, appendix)...

BACKGROUND: Chemo-resistance is a major challenge in ovarian cancer treatment, resulting in poor survival rates. Identifying markers of treatment response is imperative for improving outcome while minimizing unnecessary side effects. We have previously demonstrated that expression of transducin-like enhancer of split 3 (TLE3) is associated with favorable progression-free survival in taxane-treated ovarian cancer patients with non-serous histology. The purpose of this study was to perform an independent evaluation of the association of TLE3 expression with response to taxane-based chemotherapy in non-serous ovarian cancer, to validate its role as a potential therapeutic response marker for taxane-based chemotherapy...

Tumor-associated macrophages (TAMs) contribute to tumor progression, but it is not clear how they are recruited to tumor sites. Here we showed that periostin (POSTN) was present at high levels in ovarian cancer ascetic fluids and was correlated with CD163+ TAMs. The high POSTN level and macrophage infiltration were inversely associated with relapse-free survival for ovarian cancer patients. In vitro studies showed that co-culture with macrophages significantly increased POSTN production in ovarian cancer cells...

Because ovarian cancer often advances by dissemination, pulmonary metastases are rarely unaccompanied by intra-abdominal metastases. We report a case of ovarian clear cell carcinoma having multiple bilateral lung metastases and without concurrent intra-abdominal lesions, as demonstrated by FDG PET/CT scan.

BACKGROUND: The recurrence, metastasis and poor prognosis are important characteristics of ovarian carcinoma (OC), which are associated with exfoliation of cells from the primary tumor and colonization of the cells in pelvic cavity. On the other hand, the life quality of the patients undergoing surgical resection of OC was influenced by postoperative adhesions. Therefore, preventing postoperative implant tumor and adhesion may be effective methods to improve OC treatment. HyaRegen Gel, a cross-linked hyaluronan gel (CHAG), has been widely used as an anti-adhesive agent following pelvic operation in clinic...

BACKGROUND: High cyclooxygenase (COX)-2 expression in ovarian tumors has been associated with poor prognosis, but the role of COX-1 expression and its relation to survival is less clear. Here, we evaluated COX expression and associations with survival outcomes between type I (clear cell, mucinous, low grade endometrioid and low grade serous) and type II (high grade serous and high grade endometrioid) ovarian tumors. METHODS: We developed and validated a new COX-1 antibody, and conducted immunohistochemical (IHC) staining for COX-1 and COX-2 on a tissue microarray (TMA) of 190 primary ovarian tumors...

The telomerase reverse transcriptase (TERT) gene is highly expressed in stem cells and silenced upon differentiation. Cancer cells can attain immortality by activating TERT to maintain telomere length and telomerase activity, which is a crucial step of tumorigenesis. Two somatic mutations in the TERT promoter (C228T; C250T) have been identified as gain-of-function mutations that promote transcriptional activation of TERT in multiple cancers, such as melanoma and glioblastoma. A recent study investigating TERT promoter mutations in ovarian carcinomas found C228T and C250T mutations in 15...

Ubiquitin-specific protease 2 (USP2) belongs to the family of deubiquitinases that can rescue protein targets from proteasomal degradation by reversing their ubiquitination. In various cancers, including prostate cancer and ovarian carcinoma, upregulation of USP2 leads to an increase in the levels of deubiquitinated substrates such as fatty acid synthase, MDM2, cyclin D1 and Aurora-A. USP2 thus plays a critical role in tumor cells' survival and therefore represents a therapeutic target. Here a leukemia drug, 6-thioguanine, was found to be a potent inhibitor of USP2...

Estrogens modulate the immune system and possess anti-inflammatory properties. In line, immune cells express a variety of estrogen receptors (ER) including ER-alpha and -beta. In the present study, we examined the influence of 17beta-estradiol (E2) serum concentrations on blood leukocyte composition and their ex vivo polarization/activation status by FACS analysis in sub-fertile human females under controlled ovarian stimulation (COS). Using a set of cell-type and polarization-specific markers, we demonstrate that increased 17ß-estradiol (E2) serum concentrations yield an overall increase in leukocytes, neutrophils and monocytes but decreased lymphocytes...
