Advanced ovarian clear cell carcinoma (OCCC) carries a very poor prognosis in large part secondary to the extremely high rate of resistance to standard platinum and taxane chemotherapy. STAT3 expression and activation has been shown to regulate tumor progression in various human cancers, though has not been well studied in OCCC. Preliminary work in our lab has demonstrated constitutive activation of STAT3 (pSTAT3Tyr705 or pSTAT3727) in OCCC cell lines as well as human OCCC tumor tissue samples. Significantly, pSTAT3 is expressed in the absence of other forms of activated STAT (pSTAT1, 2, 6)...

Brenner tumors (BT) are rare ovarian tumors encompassing benign, borderline and malignant variants. While the histopathology of BTs and their clinical course is well described, little is known about the underlying genetic defects. We employed targeted next generation sequencing to analyze the mutational landscape in a cohort of 23 BT cases (17 benign, 2 borderline, 4 malignant) and 3 ovarian carcinomas with transitional cell histology (TCC). Copy number variations (CNV) were validated by fluorescence in-situ hybridization (FISH) and quantitative PCR-based copy number assays...

Cancers of the female reproductive system include ovarian, uterine, vaginal, cervical and vulvar cancers, which are termed gynecologic cancer. The emergence of long noncoding RNAs (lncRNAs), which are believed to play a crucial role in several different biological processes, has made the regulation of gene expression more complex. Although the function of lncRNAs is still rather elusive, their broad involvement in the initiation and progression of various cancers is clear. They are also involved in the pathogenesis of cancers of the female reproductive system...

Follicle-stimulating hormone receptors (FSHRs) are almost exclusively expressed on granulosa cells, and FSH action is probably most clearly reflected in intrafollicular hormone milieu of antral follicles. Little is known about the possible effects of the common single nucleotide polymorphism (SNP) FSHR -29G > A (rs1394205) on hormonal conditions in humsan small antral follicles (hSAFs) obtained from women in the natural menstrual cycle. This study investigated the follicle fluid (FF) concentrations of anti-Müllerian hormone, estradiol, progesterone, androstenedione, and testosterone in hSAF in relation to the different genotypes of FSHR -29G > A...

Expression of the retained C-terminal extracellular portion of the ovarian cancer glycoprotein MUC16 induces transformation and tumor growth. However, the mechanisms of MUC16 oncogenesis related to glycosylation are not clearly defined. We establish that MUC16 oncogenic effects are mediated through MGAT5-dependent N-glycosylation of two specific asparagine sites within its 58 amino acid ectodomain. Oncogenic signaling from the C-terminal portion of MUC16 requires the presence of Galectin-3 and growth factor receptors co-localized on lipid rafts...

OBJECTIVE: Ovarian clear cell carcinomas (OCCCs) constitute a rare ovarian cancer subtype with distinct clinical features, but may nonetheless be difficult to distinguish morphologically from other subtypes. There is limited knowledge of genetic events driving OCCC tumorigenesis beyond ARID1A, which is reportedly mutated in 30-50% of OCCCs. We aimed to further characterize OCCCs by combined global transcriptional profiling and targeted deep sequencing of a panel of well-established cancer genes...

Uterine and ovarian carcinomas have the same major histological subtypes, but whether they originate from the same cell types is a matter of ongoing debate. Uterine and ovarian endometrioid and clear cell carcinoma (ECC) and uterine and ovarian serous carcinoma (SC) may originate in the same location, or share a common lineage of differentiation. Epidemiologically, a common cellular lineage should be reflected in similar risk associations, and we explored the similarity of uterine and ovarian ECC and uterine and ovarian SC...

Hypoxia is a common feature of solid tumors. It is closely related to tumor progression. Exosomal microRNAs derived from cancers are considered to be mediators between cancer cells and the tumor microenvironment. In addition, the number of tumor-associated macrophages (TAMs) in the tumor microenvironment has also been demonstrated to correlate with tumor development. However, the relationship between tumor-secreted exosomes and TAM polarization under hypoxic conditions during tumor progression is not clear...

OTUB1 (OTU domain-containing, ubiquitin aldehyde binding protein 1) is a deubiquitinating enzyme (DUB) that belongs to the ovarian tumor (OTU) domain protease superfamily. Although it has been demonstrated to play important roles in the development of many kinds of cancer, the mechanism of OTUB1 in hepatocellular carcinoma (HCC) is not clear. The aim of this study was to explore the roles of OTUB1 in HCC progression using cell lines and 115 archived HCC samples. In addition, the clinical outcomes were also analyzed with a special focus on OTUB1 expression in HCC samples...

OBJECTIVE: This study analyzed the relation of 5 single-nucleotide polymorphisms (SNPs) in the VEGF (vascular endothelial growth factor) gene in patients with epithelial ovarian cancer (EOC), compared with patients carrying benign tumors or healthy ovaries. We studied serum VEGF levels and the relation with SNPs and association between VEGF SNPs and haplotypes with progression-free survival (PFS) in patients with cancer. METHODS: The genotyping of VEGF gene polymorphisms (-2578 C/A, -1154 G/A, -460 T/C, +405 G/C, +936 C/T) was performed in DNA isolated from blood samples of 100 women...

UBC9 is an E2-conjugating enzyme that is required for SUMOylation and has been implicated in regulating several critical cellular pathways. UBC9 is overexpressed in certain tumors, such as lung adenocarcinoma, ovarian carcinoma and melanoma, which implies that it has special clinical significance. However, the role of UBC9 in Hepatocellular carcinoma (HCC) drug responsiveness is not clear. In this study, we investigated the clinicopathological significance of UBC9 in HCC and investigated the mechanism of UBC9-mediated chemosensitivity to doxorubicin (DOX) in hepatocellular carcinoma cells...

Renal cell carcinoma (RCC) constitutes 2-3% of all types of cancers. RCCs metastasize into lungs (50-60%), lymph nodes (36%), bones (30-40%), liver (30-40%), and brain (5%) in respective percentages. RCC rarely metastasizes into ovary. Only 25 cases of ovarian tumor, which metastasized into kidneys, have been presented. In the literature, a kidney-ovary axis has been defined, and its interrelationship begins with embryological life. With this case report, we aimed both to present a very rarely seen metastasis of RCC into contralateral ovary and also to review the literature...

There has been significant progress in the understanding of the pathology and molecular biology of rare ovarian cancers, which has helped both diagnosis and treatment. This paper provides an update on recent advances in the knowledge and treatment of rare ovarian cancers and identifies gaps that need to be addressed by further clinical research. The topics covered include: low-grade serous, mucinous, and clear cell carcinomas of the ovary. Given the molecular heterogeneity and the histopathological rarity of these ovarian cancers, the importance of designing adequately powered trials or finding statistically innovative ways to approach the treatment of these rare tumors has been emphasized...

Cancer cells actively promote aerobic glycolysis to sustain their metabolic requirements through mechanisms not always clear. Here, we demonstrate that the gatekeeper of mitochondrial Ca(2+) uptake, Mitochondrial Calcium Uptake 1 (MICU1/CBARA1) drives aerobic glycolysis in ovarian cancer. We show that MICU1 is overexpressed in a panel of ovarian cancer cell lines and that MICU1 overexpression correlates with poor overall survival (OS). Silencing MICU1 in vitro increases oxygen consumption, decreases lactate production, inhibits clonal growth, migration and invasion of ovarian cancer cells, whereas silencing in vivo inhibits tumour growth, increases cisplatin efficacy and OS...
