INTRODUCTION: Limbic encephalitis generated by anti-N-methyl D-aspartate (NMDA) receptor antibodies is a severe acute neurological condition that is more prevalent in young females and is associated with an underlying tumour. The appearance of severe initial psychiatric signs and symptoms and the fact that it is accompanied by emotional disorders and severe cognitive impairment make it necessary to reconsider the contributions of neuropsychiatry to the diagnosis, development and treatment of the disease, since these have received little attention from researchers to date...

Epithelial ovarian cancer (EOC) is the most lethal gynaecological malignancy worldwide. Development of chemoresistance and peritoneal dissemination of EOC cells are the major reasons for low survival rate. Targeting signal transduction pathways which promote therapy resistance and metastatic dissemination is the key to successful treatment. Members of the ErbB family of receptors are over-expressed in EOC and play key roles in chemoresistance and invasiveness. Despite this, single-targeted ErbB inhibitors have demonstrated limited activity in chemoresistant EOC...

BACKGROUND: Neurofibromatosis type 1 (NF1: Online Mendelian Inheritance in Man (OMIM) #162200) is an autosomal dominantly inherited tumour predisposition syndrome. Heritable constitutional mutations in the NF1 gene result in dysregulation of the RAS/MAPK pathway and are causative of NF1. The major known function of the NF1 gene product neurofibromin is to downregulate RAS. NF1 exhibits variable clinical expression and is characterized by benign cutaneous lesions including neurofibromas and café-au-lait macules, as well as a predisposition to various types of malignancy, such as breast cancer and leukaemia...

Aberrant intracellular Ca(2+) signalling contributes to the formation and progression of a range of distinct pathologies including cancers. Rises in intracellular Ca(2+) concentration occur in response to Ca(2+) influx through plasma membrane channels and Ca(2+) release from intracellular Ca(2+) stores, which can be mobilised in response to activation of cell surface receptors. OGR1 (Ovarian cancer G protein coupled Receptor 1, aka GPR68) is a proton-sensing Gq -coupled receptor that is most highly expressed in cerebellum...

This systematic review and meta-analyses investigates the expression of the cell checkpoint regulator, mitotic arrest deficiency protein 2 (MAD2) in cancerous tissue and examines whether an association exists between MAD2 levels and cancer survival and recurrence. Studies investigating MAD2 expression in cancer tissue utilising immunohistochemistry (IHC) were identified by systematic literature searches of Medline, Embase and Web of Science databases by October 2015. Random effects meta-analyses were performed to generate pooled hazard ratios (HRs) with 95% confidence intervals (CIs) of overall and progression-free survival according to MAD2 expression...

Recent studies suggest that the most common and lethal type of "ovarian" cancer, high-grade serous carcinoma (HGSC), usually arises from epithelium on the fallopian tube fimbriae, and not from the ovarian surface epithelium (OSE). We have developed Ovgp1-iCreER(T2) mice in which the Ovgp1 promoter controls expression of tamoxifen (TAM)-regulated Cre recombinase in oviductal epithelium - the murine equivalent of human fallopian tube epithelium (FTE). We employed Ovgp1-iCreER(T2) mice to show that FTE-specific inactivation of several different combinations of tumour suppressor genes recurrently mutated in human HGSCs - namely Brca1, Trp53, Rb1, and Nf1 - results in serous tubal intraepithelial carcinomas (STICs) that progress to HGSC or carcinosarcoma, and to widely metastatic disease in a subset of mice...

Environmental stressors, gonadal degenerative diseases and tumour development can significantly alter the oocyte physiology, and species fertility and fitness. To expand the molecular understanding about oocyte degradation, we isolated several spliced variants of Japanese anchovy hatching enzymes (AcHEs; ovastacin homologue) 1 and 2, and analysed their potential in oocyte sustenance. Particularly, AcHE1b, an ovary-specific, steroid-regulated, methylation-dependent, stress-responsive isoform, was neofunctionalized to regulate autophagic oocyte degeneration...

Recently, a large number of studies have focused on the important role of long non-coding RNAs (lncRNAs) in metabolism and development and have found that abnormal lncRNA expression is associated with the pathogenesis and development of many diseases. The lncRNA DLEU1 is involved in many solid tumours and haematological malignancies. However, its role in epithelial ovarian carcinoma (EOC) and the associated molecular mechanisms has not been reported. In this study, quantitative reverse transcription-PCR (qRT-PCR) demonstrated higher lncRNADLEU1 expression in EOC tissues than in normal tissues...

BACKGROUND: Peritoneal dissemination and retroperitoneal lymph node involvement are main routes for progression of epithelial ovarian cancer (EOC). Vascular endothelial growth factor (VEGF) mediated angiogenesis has been identified as an important mechanism promoting tumour progression. METHODS: Tumour tissue of 100 patients with EOC was analysed for protein expression of vascular endothelial growth factor (VEGF)-A, -C, -D by Western Blot analysis. Expression patterns in patients with 'extensive intraperitoneal' metastases (pT3c pN1 and pT3b-pT3c pN0, n=80) were compared to patients with 'predominantly retroperitoneal' metastases (pT1a-pT3b, pN1, n=20)...

Peritoneal malignancy (PM) is predominantly metastatic spread from advanced gastrointestinal or gynaecological cancer. PM is generally considered incurable and therefore has rarely been the focus of novel therapeutic strategies. This study assessed patterns and survival outcomes for patients with PM in Ireland. The National Cancer Registry Ireland database was interrogated to identify patients diagnosed with PM during the period 1994-2012. Patient and tumour characteristics were retrieved and survival outcomes calculated...

The synthetic resveratrol analogue DMU-212 (3,4,4',5-tetramethoxystilbene) has been shown to possess stronger anticancer activity than resveratrol in a variety of tumour cells. To date, there has been no appropriate procedure that would ensure a reliable data about levels of metabolic products of DMU-212 in cancer cell lines. The purpose of this study was to develop a new procedure for determination of DMU-212 and its three metabolites (DMU-214, DMU-281, DMU-291) in cell lines. Analyses were performed using an HPLC system coupled with a triple quadrupole mass spectrometer operating in multiple reaction monitoring mode...

T-box factors comprise an archaic family of evolutionary conserved transcription factors that regulate patterns of gene expression essential for embryonic development. The T-box transcription factor 3 (TBX3), a member of this family, is expressed in several tissues and plays critical roles in, among other structures, the heart, mammary gland and limbs and haploinsufficiency of the human TBX3 gene is the genetic basis for the autosomal dominant disorder, ulnar-mammary syndrome. Overexpression of TBX3 on the other hand has been linked to several cancers including melanoma, breast, pancreatic, liver, lung, head and neck, ovarian, bladder carcinomas and a number of sarcoma subtypes...

Cells with long polar hair-like processes referred to as 'flower pot cells' are a rare but beautiful morphological feature observed in effusions of diverse etiologies. This report describes these cells in effusions seen in ovarian borderline serous tumours, malignant mesothelioma and in reactive mesothelial cells with or without accompanying malignant cells. These processes were better appreciated in air-dried May-Grunwald-Giemsa stained smears.

AIMS: Low grade serous neoplasms of the testis are rare neoplasms that demonstrate striking morphological similarities with the better-understood ovarian neoplasms. The cell of origin, relation to serous ovarian tumour and the pathogenesis of these neoplasms are not fully established. METHODS AND RESULTS: As low grade serous ovarian neoplasms are known to harbour mutations in the MAP-kinase pathway, we investigated the involvement of BRAF and KRAS mutations in low grade testicular serous tumour by way of mutational analysis of 7 cases...
