Adrenomedullin immunoreactivity tissue distribution in parathyroids of the patients with primary hyperparathyroidism.

Adrenomedullin (ADM) is a new potent vasorelaxant peptide identified originally in extracts of pheochromocytoma, and is widely distributed within the tissue. Although histopathological studies have demonstrated the presence of ADM-immunoreactivity (ir-ADM) in some human neuroendocrine tumors (such as insulinoma, pituitary adenoma, and gastrointestinal neuroendocrine tumors), data on the presence of ADM in normal and pathological parathyroid gland are not available. Plasma AM concentrations were recently reported to be elevated in patients with PHP (primary hyperparathyroidism).

Inability of immunohistochemistry to predict clinical outcomes of endometrial cancer patients.

Introduction: Despite optimal surgery, some patients with early endometrial carcinoma develop recurrence and die of disease. A number of immunohistochemical (IHC)-identified cell products (markers) have been proposed as predictors of recurrence. This study characterizes a large series of endometrial carcinomas with previously described markers as well as markers that have not been investigated in endometrial carcinoma.

Fatty acid synthase is a marker of increased risk of recurrence in endometrial carcinoma.

Purpose: To explore the expression of fatty acid synthase (FAS) and human erythrocyte glucose transporter 1 (GLUT1) in endometrial carcinomas and to detect associations with clinicopathological features and prognosis. FAS and GLUT1 are two molecules involved in energy supply of normal cells. These markers are overexpressed in neoplastic tissues because of their increased necessity of energy.

Immunohistochemical localization of the growth hormone in human endometrium and decidua.

Problem: Recent evidence of growth hormone (GH) receptor expression in rat endometrium and human myometrium have focused our attention on the role of the GH in endometrial development. We tested the expression of GH in the human endometrium throughout the menstrual cycle and during pregnancy.

Method Of Study: Immunohistochemical study was performed on endometrial specimens of fertile women in different periods of the menstrual cycle and in decidua of pregnant women.

Tight junction proteins claudin-3 and claudin-4 are frequently overexpressed in ovarian cancer but not in ovarian cystadenomas.

Purpose: Claudin proteins represent a large family of integral membrane proteins crucial for tight junction (TJ) formation and function. Claudins have been shown to be up-regulated in various cancers and have been suggested as possible biomarkers and targets for cancer therapy. Because claudin-3 and claudin-4 have been proposed to be expressed in epithelial ovarian cancer, we have performed a detailed analysis of CLDN3 and CLDN4 expression in a panel of ovarian tumors of various subtypes and cell lines.
