Upregulation of DJ-1 mRNA is commonly observed in various human cancers such as ductal carcinoma of the breast, non-small cell carcinoma of the lung, pancreatic duct adenocarcinoma, urinary transitional cell carcinoma, and gynecologic carcinoma. At the protein level, intensity and intracellular localization of DJ-1 expression is varied, and the DJ-1 protein regulates cancer progression, clinical aggressiveness, differentiation, cancer cell morphology, and drug sensitivity. Thus, DJ-1 plays a critical role in cancer...

Ovarian cancer (OC) is the most common cause of mortality from malignant gynecological cancers. Its lethality is mainly a result of tumors that are difficult to detect at the early stage and a lack of effective systemic therapy for advanced status cancer. MicroRNAs (miRNAs/miRs) are a category of single-stranded non-coding small RNAs that bind to their target mRNAs, and aberrant expression levels of miRNAs may serve key roles in regulating cell migration and invasion of various types of human cancer. Previous studies have demonstrated that miR-18b may function as an oncogene in numerous types of tumors, but its role and molecular mechanism in OC remained unclear...

Clear cell renal cell carcinomas (CCRCC) rarely metastasizes to the gynecologic tract. In this study, we analyzed a multi-institutional data set to provide insights into the clinical, morphologic, and immunophenotypic features of this phenomenon. Seveteen metastatic CCRCC involving the gynecologic tract [ovary/fallopian tube (n=9), vulva (n=2), uterine corpus (n=3), cervix (n=2), uterine serosa (n=1)] were analyzed. Mean patient age was 62 yr (range: 45-79 yr). Most cases (15/17) presented as a recurrence 6 to 72 mo postnephrectomy, 1 case was concurrently diagnosed, and 1 case (a cervical metastasis) was diagnosed prenephrectomy...

Ovarian germ cell tumors (OGCTs) and sex cord stromal tumors (SCSTs) are rare gynecologic tumors that are derived from germ and stromal cells, respectively. Unlike their epithelial counterparts, molecular pathogenesis of these tumor types is still poorly understood. Here, we characterized microRNA (miRNA) expression profiles of 9 OGCTs (2 malignant and 7 benign) and 3 SCSTs using small RNA sequencing. We observed significant miRNA expression variations among the three tumor groups. To further demonstrate the biological relevance of our findings, we selected 12 miRNAs for validation in an extended cohort of 16 OGCTs (9 benign and 7 malignant) and 7 SCSTs by reverse transcription-quantitative polymerase chain reaction...

Ovarian cancer (OC) is the leading cause of death in gynecological malignancies in western countries. Chemoresistance represents a major issue and a better understanding of the interactions that take place within the tumor microenvironment is needed, such as the connection between inflammation and cancer. Toll like receptors (TLRs) are part of the basic mechanisms that are involved in the activation of the innate immune system, with extensive activation of various transcription factors, that subsequently lead to an adaptive immune response, making them key players that modulate the inflammatory response and tumor dynamics...

Ultrasonography (US) is frequently the first imaging modality used to examine women with symptoms involving the pelvis. It is widely available and involves no exposure to ionizing radiation. Images can be acquired with a transabdominal, endovaginal, or translabial approach, and the use of video clips and three-dimensional reconstructions can be helpful. US is excellent for assessment of the uterus, ovaries, and adnexa. Occasionally, nongynecologic pelvic diseases arising from the gastrointestinal, genitourinary, and musculoskeletal systems and the pelvic peritoneal and extraperitoneal spaces may be detected and can be a source of diagnostic dilemma...

Ubiquitylation is a tightly regulated process that is essential for appropriate cell survival and function, and the ubiquitin pathway has shown promise as a therapeutic target for several forms of cancer. In this issue of the JCI, Kedves and colleagues report the identification of a subset of gynecological cancers with repressed expression of the polyubiquitin gene UBB, which renders these cancer cells sensitive to further decreases in ubiquitin production by inhibition of the polyubiquitin gene UBC. Moreover, inducible depletion of UBC in mice harboring tumors with low UBB levels dramatically decreased tumor burden and prolonged survival...

Transcriptional repression of ubiquitin B (UBB) is a cancer-subtype-specific alteration that occurs in a substantial population of patients with cancers of the female reproductive tract. UBB is 1 of 2 genes encoding for ubiquitin as a polyprotein consisting of multiple copies of ubiquitin monomers. Silencing of UBB reduces cellular UBB levels and results in an exquisite dependence on ubiquitin C (UBC), the second polyubiquitin gene. UBB is repressed in approximately 30% of high-grade serous ovarian cancer (HGSOC) patients and is a recurrent lesion in uterine carcinosarcoma and endometrial carcinoma...

Cervical cancer remains one of the most common causes of gynecological cancer-associated death. Long non-coding RNA Loc554202 (lncRNA Loc554202) has been reported to be involved in the development of several types of cancer. However, the role of Loc554202 in cervical cancer remains unclear. In this study, we measured the expression levels of Loc554202 in cervical cancer tissues from 120 patients. The quantitative real-time PCR analysis showed the expression levels of Loc554202 were significantly higher in cervical cancer tissues compared with the adjacent non-tumor tissues...

Decreased epithelial cadherin (E-cadherin) expression is hypothesized to be related to poor prognosis of ovarian cancer, but the predictive value is still inconsistent. We conducted an updated meta-analysis with a total of 16 studies enrolling 1720 patients to estimate the prognostic value of decreased E-cadherin expression in ovarian cancer. Reduced expression of E-cadherin was significantly associated to poor overall survival (HR = 1.74, 95% CI: 1.40-2.17) and progression-free survival (HR = 1.45, 95% CI: 1...

AIMS: Solitary fibrous tumor (SFT) is an uncommon spindle cell neoplasm of fibroblastic origin, first described as a tumor of the pleura and now well established at extrapleural sites. However, SFT in the female genital tract is rare and therefore not fully characterized. MATERIAL AND RESULTS: We describe a series of 25 SFTs arising throughout the gynecologic tract, including vulva (14 cases), vagina (1), cervix (1), uterus (6), ovary (2) and fallopian tube (1)...

Magnetic resonance imaging (MRI) is the optimal modality for local staging of gynecological tumors. Advances in functional MRI with diffusion-weighted and dynamic contrast-enhanced sequences provide more detailed information regarding tumor cellularity, vascularity, and viability. Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) now has an established role in imaging for gynecological cancers, particularly staging of locally advanced cervical cancers and pre-salvage exenterative therapy in relapsed gynecologic tumors...
