    ABSTRACT: Mouse bone marrow mesenchymal stem cells (BMSCs) have been demonstrated to differentiate into female endometrial epithelial cells (EECs) in vivo. Our previous studies demonstrated that BMSCs can differentiate in the direction of EECs when co-cultured with endometrial stromal cells in vitro. Here, we obtain and analyse differential proteins and their relevant pathways in the process of BMSCs differentiating into EECs by isobaric tags for relative and absolute quantitation (iTRAQ) proteomic analysis.

    ABSTRACT: To analyze the clinical characteristics of ovarian masses in children and adolescents. We performed a retrospective analysis of patients less than 20 years of age who were treated at the Obstetrics and Gynecology Hospital of Fudan University between March 2003 and January 2012. Medical records were reviewed for age at operation, including presentation of symptoms and signs; the levels of tumor markers; imaging examinations; pathologic findings; the size of masses; treatment; and outcome. Data management and descriptive analyses were performed using SPSS 16.0. A total of 521 patients were included in this study. Among them, 92 had non-neoplastic lesions, 382 had benign neoplasms, and 47 had malignant tumors. The mean age of the patients was 16.3 ± 2.2 years. The primary presenting symptoms and signs were abdominal pain (39.5%), menstrual disorder (31.1%), abdominal swelling (5.4%), and an enlarged abdominal perimeter (3.3%). Malignant tumors tended to be larger than benign neoplasms (17.3 ± 8.6 cm vs 9.0 ± 5.7 cm; P = .000). There was no age difference between patients with benign neoplasms (16.3 ± 2.1 y) and those with malignant tumors (15.7 ± 2.5 y). The operations included salpingo-oophorectomy, ovarian cystectomy, and oophorectomy. Two patients with malignant tumors had bilateral salpingo-oophorectomy, and 2 patients who had tumor metastasis underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy. Forty-one cases of malignant tumors received postoperative chemotherapy. Germ cell tumors are the most common malignancy, and mature teratomas are the most common benign neoplasms in children and adolescents. Abdominal pain and menstrual disorder are the main reasons for doctor's visit. Although examination by ultrasound is the preferred auxiliary in the diagnosis of ovarian pathology, it could not distinguish between benign and malignant tumors. However, tumor size and tumor markers are helpful to identify the properties of masses. Surgery is usually better for treatment, and it is preferable to attempt conservative, fertility-sparing surgery in adolescents. Postoperative chemotherapy is necessary for malignant tumors.

    ABSTRACT: Melanoma cell adhesion molecule (MCAM) is a cell adhesion molecule that is abnormally expressed in a variety of tumours and is closely associated with tumour metastasis. The role of MCAM in ovarian cancer development has not been fully studied. In this study, through immunohistochemical staining of ovarian cancer tissue samples and RNA interference to silence MCAM in ovarian cancer cells, we examined the impact of MCAM on the biological functions of ovarian cancer cells and attempted to reveal the role of MCAM in ovarian cancer development. Our results showed that MCAM expression was particularly high in metastatic ovarian cancers compared with other pathological types of ovarian epithelial tissues. After MCAM silencing in the MCAM high-expression ovarian cancer cell line SKOV-3, the cell apoptosis was increased, whereas the cell spreading and invasion were significantly reduced, which may be related with dysregulation of small RhoGTPase (RhoA and Cdc42).These results suggest that MCAM expression in ovarian cancer is highly correlated with the metastatic potential of the cancer. MCAM is likely to participate in the regulation of the Rho signalling pathway to protect ovarian cancer cells from apoptosis and promote their malignant invasion and metastasis. Therefore, MCAM can be used not only as a molecular marker to determine the prognosis of ovarian cancer but also as a therapeutic target in metastatic ovarian cancer.
