Death-associated protein 1 (DAP1) is a small proline-rich cytoplasmic protein that functions both in the apoptosis and autophage process of mammalian and in the clinical cancer of human. However, little knowledge is known about the homologue gene of DAP1 and its roles in the physiological process of invertebrates. In this paper, we report a novel function of DAP1 in the antivirus immunity of shrimp. A homologue gene of DAP1 was cloned from Marsupenaeus japonicus and named as Mjdap-1. The full-length of Mjdap-1 was 1761 bp with a 309 bp open reading frame that encoded 102 amino acids...

C-Met is a receptor tyrosine kinase with multiple functions throughout embryonic development, organogenesis and wound healing and is expressed in various epithelia. The ligand of c-Met is Hepatocyte Growth Factor (HGF) which is secreted among others by mesenchymal stroma/stem (MSC) cells.Physiological c-Met functions are centred around processes that underly cellular motility and invasive growth. Aberrant c-Met expression and activity is observed in numerous cancers and makes major contributions to cell malignancy...

In this study, the relationship between ovarian function and ovarian limited dose in radiotherapy was evaluated in young patients with cervical cancer who underwent ovarian transposition (Fig1B). Moreover, the novel ovarian dose limit for a better preservation of ovarian function in intensity-modulated radiation therapy (IMRT) was determined. We retrospectively analyzed data from 86 patients with cervical cancer who received radical hysterectomy and ovarian transposition from January 2013 to June 2015. In agreement with the National Comprehensive Cancer Network Guidelines (NCCN) for Cervical Cancer Version 2...

REVIEW
Panayiotis Constantinou, Marc Tischkowitz
Gynaecological cancers accounted for 16.3% of all cancers and 13.9% of all cancer deaths in women globally in 2012. Cancer of the cervix is the most common gynaecological cancer, followed by cancers of the uterus and the ovary. Although cervical cancer is almost exclusively triggered by human papilloma virus infection, approximately 5% of all uterine cancers and 20% of all ovarian cancers are caused by germline mutations in cancer predisposition genes. A number of genetic syndromes are associated with rarer gynaecological tumours...

PURPOSE: Extracting ovarian tissue before oncologic therapy and transplanting it afterwards are increasingly being used to preserve fertility in women. This study describes standardized and safe operative procedures, with few complications, and reports the resulting ovarian function and pregnancy rates. METHODS: The standardized operative techniques for removing and transplanting ovarian tissue used at the Erlangen center are: for tissue removal, one-third to half of the tissue from one ovary is excised with scissors, without tissue coagulation; for subsequent transplantation, pieces of ovarian tissue are placed in a retroperitoneal pocket without closure of the pocket...

PURPOSE: Synchronous endometrial and ovarian tumors (SEOs) are diagnosed in 10% of ovarian cancer patients. We examined predictors of SEOs, evaluated associations of SEOs with survival and characterized ovarian tumor profiles using immunohistochemistry. METHODS: We included patients with endometrioid (n = 180) and clear cell (n = 165) ovarian carcinoma identified from the Alberta Cancer Registry between 1979 and 2010 for whom we abstracted medical records and constructed tumor tissue microarrays (TMAs)...

This review article summarizes the role of PET/CT and PET/MRI in ovarian cancer. With regard to the diagnosis of ovarian cancer, the presence of FDG uptake within the ovary of a postmenopausal woman raises the concern for ovarian cancer. Multiple studies show that FDG PET/CT can detect lymph node and distant metastasis in ovarian cancer with high accuracy and may, therefore, alter the management to obtain better clinical outcomes. Although PET/CT staging is superior for N and M staging of ovarian cancer, its role is limited for T staging...

The study reported here demonstrates that a flaxseed-supplemented diet causes ovarian tumors in the laying hen to undergo apoptosis, resulting in a reduction of tumor burden, reducing the frequency and severity of ovarian cancer. We have previously shown in normal ovaries that flaxseed and its components down-regulate ERalpha and alter the expression of enzymes that metabolize estrogen. In this study, we analyzed the effects of the two main components of whole flaxseed, ligan and omega 3 fatty acids on estrogen metabolism and the estrogen receptor in ovarian tumors...

INTRODUCTION: Women with polycystic ovary syndrome (PCOS) have a 3-fold higher risk of endometrial cancer (EC). Insulin resistance and hyperlipidaemia may be pertinent factors in the pathogenesis of both conditions. The aim of this study was to investigate endometrial Sterol Regulatory Element Binding Protein-1 gene (SREBP1) expression in PCOS and EC endometrium, and to correlate endometrial SREBP1 expression with serum lipid profiles. MATERIAL AND METHODS: A cross-sectional study was performed at Nottingham University Hospital, United Kingdom...

BACKGROUND: This case report draws attention to the debated role of prophylactic oophorectomy in women undergoing definitive surgical resection of colon and rectal cancers. It can be challenging to discern the indications and appropriate patient population for this procedure based on the current literature. Potential benefits include treatment and prevention of metastatic disease, preventing development of primary ovarian cancer, and prolonging survival. Negative effects include an increase in operative time and potential morbidity, development of osteoporosis, the risk of cardiac events, and decreasing sexual function...

BACKGROUND: Screening for benign or malignant process of pelvis in young females is a challenge for a physician in a limited resource country. Tuberculosis should be always considered in the differential diagnosis of a pelvic mass in countries with high prevalence of tuberculosis. Negative results of analysis of peritoneal fluid for acid-fast staining, late cultures, and unavailability of new diagnostics methods such as polymerase chain reaction and adenosine deaminase of the aspirated fluid from peritoneal cavity can often result in invasive diagnostic procedures such as laparotomy...

: 202 Background: Cancer pain is the most important problem to overcome in terminally ill cancer patients (TICPs). Recently, the fentanyl patch (FP) has been widely used for the treatment of cancer pain. However, the FP requirement largely varies in patients. The purpose of this study was to identify the determinants of the FP requirement in TICPs and propose effective pain relief using a FP. METHODS: In a retrospective chart review, we investigated cancer patients who were admitted in our hospital from April 2012 to July 2015 and used FP until their deaths...

: 95 Background: Operative reports (OP) for cancer surgery are usually narrated, although they provide inconsistent and incomplete information for patient care. National standards for cancer OP were unavailable until 2007. Over 10 years, surgeons in four Canadian provinces have transitioned from narrative to electronic synoptic reporting (ESP) for specific cancers. The electronic OP are now considered a patient medical record and integral to subsequent patient care. Surgeons are using electronic reports for quality assurance, billing, medical-legal conflict resolution and research...

The stomach is an infrequent localization of tumor metastases, and metastases originating from primary gynaecological cancers are particularly rare. We described the case of three females with ovarian, uterine, and breast metastases in the stomach, and we performed a systematic review of the literature of cases diagnosed at endoscopy. Overall, data of 18 patients with gastric metastases originating from the ovary, 11 from the uterus, and 159 from breast cancer were analyzed. Therefore, gastric metastasis mainly occurs from breast cancer, whilst both ovarian and uterine metastases are distinctly less frequent, but not impossible...

E2F1 (E2F transcription factor 1) can act as a tumor suppressor or oncogene. We report the molecular mechanism of E2F1 in ovarian carcinoma tumorigenesis and progression. E2F1 expression levels in ovarian carcinoma tissue were examined by immunohistochemistry. After E2F1 plasmid transfection and E2F1-microRNA-519d (miR-519d)/si-RhoC (Ras homolog gene family member C) co-transfection, ovarian cancer cell phenotypes and the related molecules were examined in vitro and in vivo. E2F1 was overexpressed in type I and type II ovarian carcinoma as compared to normal ovary tissues and normal fallopian tube tissues, respectively...
