PTEN is a tumor suppressor gene mutated in many human cancers. We used the Cre-loxP system to generate an urothelium-specific null mutation of Pten in mice [FabpCrePten(flox/flox) (FPten(flox/flox)) mice]. Histologic examination revealed that all FPten(flox/flox) mice exhibited urothelial hyperplasia in which component cells showed enlarged nuclei and increased cell size. With time, 10% of FPte...
BACKGROUND Recent evidence indicates that elevated COX-2 expression is associated with the carcinogenesis of numerous neoplasms. In this study, we investigated COX-2 expression in various thyroid specimens in order to elucidate its physiological role in pathologic conditions, and to evaluate the efficiency of COX-2 protein expression as a molecular marker of malignancy in the thyroid gland. M...
The incidence of Papillary Thyroid Carcinoma (PTC) has increased gradually in recent years, especially for Papillary Thyroid Microcarcinoma (PTMC). The purpose of this study was to evaluate the expression of Ki67, CK19, Galectin-3 and HBME-1 protein in PTMC and evaluate the clinical significance of differential diagnosis. The specimens of 80 PTMC cases and 40 benign papillary hyperplasia thyroi...
