Incidental occurrence of high grade serous tubal adenocarcinoma after prophylactic adnexectomy in benign gynecological surgery.

Objective: Describtion of the case of incidental occurence of high grade serous tubal adenocarcinoma.

Design: Case study.

Setting: II.

Expression of MDR proteins in breast cancer and its correlation with some clinical and pathological parameters.

The aim of this work was to determine the expression of the multidrug resistance (MDR) proteins, namely MDR1 (P-glycoprotein), MRP1 (multidrug resistance-related protein) and LRP (lung resistance-related protein), in 87 samples of breast carcinoma. Detection of these proteins was provided by using indirect enzymatic immunohistochemistry. Our findings were compared with the other clinical and pathological parameters: expression of Her2/neu, estrogen receptor status (ER), progesteron receptor status (PR), histological grade and regional lymph node status.

Immunohistochemical detection of MRP1 protein in normal and hyperplastic human thyroid gland.

In this study we describe the localization of MRP1 in normal and hyperplastic thyroid tissues. To demostrate this protein we have used the enzyme imunohistochemical method with monoclonal antibody MRPm6. We have found MRP1 to be present in follicular epithelial cells of normal thyroid tissue and higher expression in the same cells of hyperplastic thyroid tissue.

Expression of the multidrug resistance-associated protein 1 (MRP1) and the lung resistance-related protein (LRP) in human lung cancer.

Fifty lung cancer samples (41 non-small cell lung cancer-NSCLC and 9 small cell lung cancer-SCLC) were immunohistochemically analyzed for lung resistance-related protein (LRP) and multidrug resistance-associated protein 1 (MRP1) expressions which were then correlated with histopathological subtype of the tumor. To detect these proteins, monoclonal antibodies LRP-56 and MRPm6 were used. NSCLC samples were divided into two groups, adenocarcinomas (17 samples) and squamous cell carcinomas (24 samples).
