BACKGROUND Ovarian cancer is the second most common malignant tumor of the female reproductive system and is the leading cause of death of gynecological malignancies, but at present there is no effective and safe therapy. There is no previously published report on the anti-cancer effect of prucalopride, which is a high-affinity 5-HT4 receptor. The aim of the present study was to determine whether prucalopride can inhibit proliferation of ovarian cancer cells. MATERIAL AND METHODS The cell viability was detected by use of the Cell Counting Kit-8 (CCK-8) assay...

As one of the commonest gynecological malignancies in the world, cervical cancer brings great threat for public health. Long non-coding RNAs (LncRNAs) have been proved to be closely related to the progression of various cancers, including cervical cancer. As a tumor promoter, lncRNA XIST has been reported in various malignant tumors. In this study, we aim to explore the specific mechanism and biological function of XIST in cervical cancer. At first, the expression levels of XIST were examined in both tissues and cell lines with qRT-PCR...

Ovarian cancer is one of the most common gynecologic malignancy with poor prognosis. Recently, long noncoding RNAs (lncRNAs) have been identified as key regulators in cancer development. The current study investigated the role of lncRNA P73 antisense RNA 1T (TP73-AS1) in ovarian cancer. Quantitative real-time polymerase chain reaction determined the expression levels of TP-73AS1, matrix metallopeptidases (MMPs) messenger RNA. Cell proliferative ability, cell invasion, and migration were CCK-8 and colony formation, and transwell invasion and migration assays, respectively...

Ovarian cancer (OC) is the leading cause of death from gynecological malignancy. Accumulated studies have revealed that targeting protein for Xklp2 (TPX2) was tightly associated with the development and progression of OC. The present study further determined a novel mechanism of TPX2 in OC via the AKT signaling pathway. The differentially expressed genes were screened in GEO database for gene expression microarray of OC. Bioinformatics was used to analyze the key differentially expressed genes in OC. We prepared CD133/1+ OC stem cells...

Ovarian cancer (OC) is the most lethal gynecological malignancy, with a low 5-year survival rate. Most patients with ovarian cancer are diagnosed in late-stages. A rising number of non-coding RNAs (ncRNAs) have been found to act as key regulators of gene expression by applying novel high-thought methods, such as next generation sequencing (NGS). Non-coding RNAs not only play important roles in carcinogenesis, but also affect the clinical treatment strategies. One of the biggest challenge in OC treatment was chemoresistance, which causes poor prognosis and high recurrence rate after applying traditional remedies...

Born in 1883 in Kyme, Greece, George Papanicolaou obtained his medical degree in 1904 from the University of Athens and doctorate in Zoology in 1910 from the University of Munich. He migrated to the USA in 1913 and worked as an assistant at the Department of Anatomy in the Cornell Medical College. There, Papanicolaou examined vaginal smears under his microscope, charted the cyclic ovarian and uterine changes every day and harvested the oocytes at the appropriate time. He published his research on the cytologic patterns in guinea pigs in the American Journal of Anatomy in 1917...

We present a case of a 63-year-old female who initially presented with complaints of vulvar swelling and was subsequently found to have isolated retroperitoneal lymphadenopathy on imaging. Biopsy was performed and was indicative of weakly polarizable material that raised the consideration of joint prosthesis wear debris. Due to the patient's concern for an underlying malignancy of gynecologic origin, a laparoscopic lymphadenectomy was ultimately performed and final pathology was consistent with reactive changes due to joint wear and debris from the patient's bilateral total knee arthroplasties placed approximately 16 years prior...

Ovarian carcinoma is a fatal malignancy in gynecological malignancies, and the prognosis still remains poor due to the lack of effective therapeutic targets. This study demonstrated that centromere protein U (CENPU) was up-regulated in ovarian cancer. The ectopic expression of CENPU in ovarian cancer cells expedited the proliferation, migration and invasion of ovarian cancer cells in vitro. Besides, the over-expression of CENPU markedly advanced the tumorigenicity of ovarian cancer cells in vivo whereas knocked-down CENPU resulted in opposite outcome...

Malignant bowel obstruction (MBO) is a major complication in women with advanced gynecologic cancers which imposes a significant burden on patients, caregivers, and healthcare systems. Symptoms of MBO are challenging to palliate and result in progressive decompensation of already vulnerable patients with limited therapeutic options and a short prognosis. However, there is a paucity of guidelines or innovative approaches to improve the care of women who develop MBO. MBO is a complex clinical situation that requires a multidisciplinary approach to ensure the appropriate treatment modality and interprofessional care to optimally manage these patients...

OBJECTIVE: Dysgerminoma is the most common malignant ovarian germ cell tumor (GCT) with peak incidence during adolescence and young adulthood. Current standard of care for patients with disease that has spread outside of the ovary (advanced-stage) utilizes platin-based chemotherapy regimens. The study objective was to compare clinical outcomes between platin-based (carboplatin versus cisplatin) strategies across all age groups (children < 11 years (y), adolescents = 11-25 y and young adult women > 25 y) for advanced-stage dysgerminoma...

Epithelial ovarian cancer is the sixth most common cancer among women worldwide and the first cause of death among gynecological malignancies. Most of the patients present recurrent disease and unfortunately cannot be cured. The unsatisfactory results obtained with salvage chemotherapy have elicited investigators to search for novel biological agents capable of achieving a better control of the disease. In the setting of homologous recombination deficiency, the DNA errors that occur cannot be accurately repaired, and the treatment with poly(ADP-ribose) polymerase (PARP) inhibition results in definitive cell death in a process called synthetic lethality...

High-grade serous ovarian carcinoma (HGSOC) is one of the most lethal gynecologic malignancies. Currently, anti-angiogenesis therapy is the most promising strategy for the successful treatment of HGSOC. In this study, we found Neferine could inhibit the angiogenesis of ovarian cancer cells both in vitro and in vivo. Further analysis revealed that its suppressive effect on human umbilical vein endothelial cell (HUVEC) proliferation correlated with promoting cell cycle arrest and autophagy. The cell cycle genes were dose-dependently reduced and the level of LC3II/LC3I (microtubule associated protein 1 light chain 3) was increased...

Cervical cancer is a common gynecological malignancy with high incidence and mortality. Drugs commonly used in chemotherapy are often accompanied by strong side-effects. To find an anti-cervical cancer drug with high effects and low toxicity, luteoloside was used to treat the cervical cancer cell line Hela to investigate its effects on cell morphology, proliferation, apoptosis, and related proteins. The study demonstrated that luteoloside could inhibit proliferation remarkably; promote apoptosis and cytochrome C release; decrease the mitochondrial membrane potential and reactive oxygen species level; upregulate the expression of Fas, Bax, p53, phospho-p38, phospho-JNK, and cleaved PARP; downregulate the expression of Bcl-2 and phospho-mTOR; activate caspase-3 and caspase-8; change the nuclear morphology, and fragmentate DNA in Hela cells...

Radiation induced morphea (RIM) is an increasingly common complication of radiation treatment for malignancy as early detection has made more patients eligible for non-surgical treatment options. In many cases, the radiation oncologist is the first person to learn of the initial skin changes, often months before a dermatologist sees them. In this paper we present a breast cancer patient who developed a rare bullous variant of RIM, which delayed her diagnosis and subsequent treatment. It is imperative to diagnose RIM early as it carries significant morbidity and permanent deformity if left untreated...
