Introduction. Lipocortin-1 (annexin-1 and p35) is a 37-kDa Ca2+-dependant membrane-binding protein that hasanti-inflammatory, anti-mitotic and anti-proliferative properties.With these properties in mind it was hypothesised that lipocortin-1 may have an important role in the endometrium. Therefore, the aim ofthis study was to determine the distribution of lipocortin-1 in normal and abnormal endometrial tissue.Methods. Formalin fixed paraffin embedded sect...

IntroductionSomatostatin has antiproliferative, anti-angiogenic and pro-apoptotic actions through 5 G-protein receptors (Sstr). In view of the anti-angiogenic effects of Sstrs their relationship to the distribution of vascular endothelial growth factor (VEGF) was undertaken in non-malignant Reinke's Oedema of the larynx and squamous cell carcinoma of the larynx.MethodsSix Reinke's oedema (non malignant) and 1...

Introduction: Somatostatins are physiological down regulatory proteins that act via 5 different transmembrane receptors (SSTR1-5, including isoforms SSTR-2a & 2b) via GTP binding proteins. The aim of this study was to determine the distribution of somatostatin receptors in thyrocytes of different thyroid pathologies.Method: Formalin fixed paraffin embedded sections from archival tissue were immunostained. Sections underwent dewaxing and rehydration before microwave ant...

Lipocortin 1 (LC1) is a well-characterized anti-inflammatory, -anti mitotic and anti-proliferative member of a structurally related family of Ca2+ and phospholipid-binding proteins. LC1 is readily detectable in the neuroendocrine system by Western blot analysis, ELISA, and immunohistochemistry (1). In these tissues, glucocorticoids regulate both the expression and subcellular distribution of LC1. Other studies have also demonstrated the presence of LC1 in endometrium tissue th...
