objective(s) galectin-3 (gal-3) is a member of the b-galactoside-binding lectins which is expressed in a variety of tissues and plays a role in diverse biological events, such as embryogenesis, adhesion, cellular proliferation, and apoptosis. in this study, the presence and distribution of galectin-3 (gal-3) in the mouse testicular tissue was investigated. materials and methods eight adult nmri...

Oral cancers of tobacco and betel chewers represents a unique in-vivo model to understand the genotoxic effect of tobacco and betel carcinogens on oncogenes and tumor suppressor genes. Coordinated interactions of p53 and MDM2 play an important role in regulation of critical growth control gene following exposure to DNA damaging agents. The purpose of this study is to determine if the tumor supp...

Context The selective arterial secretagogue injection test is a functional examination to determine localization of functional neuroendocrine tumor. Since the selective arterial secretagogue injection test capitalizes on the hormone-secreting ability of neuroendocrine tumor, no reports on this test in non-functional neuroendocrine tumors have yet been published. Objective In this study, we eval...

OBJECTIVES Follicle stimulating hormone (FSH) receptors (FSHR) are physiologically expressed in the ovary and testis. It is well known that FSHR are also expressed in gonadal cancers, but the data on their incidence in extra-gonadal tumors are scarce. Recently, the expression of FSHR in the vascular endothelium within different human cancers was found, but nothing is known on FSHR appearance in...

Introduction To evaluate the expression patterns of cytokeratin (K) 12, 13, and 19 in normal epithelium of the human ocular surface to determine whether K13 could be used as a marker for conjunctival epithelium. Methods: Total RNA was isolated from the human conjunctiva and central cornea. Those transcripts that had threefolds or higher expression levels in the conjunctiva than the cornea wer...

Ploidy and growth fraction were analyzed by means of a computer-assisted image processor in surgically resected non-small cell lung cancer (NSCLC). This study was done in order (a) to evaluate the distribution of anti-Ki-67 immunostaining and (b) to correlate this distribution to ploidy status and pTNM stage of NSCLC. Thirty-two patients underwent a surgical resection for primary NSCLC followin...

Male rat pituitary glands, diethylstilbestrol (DES)-induced rat pituitary tumors and 12 human pituitary adenomas were immunostained with antibodies raised against AT1 and AT2 angiotensin receptor proteins. Positive immunostaining of AT1 was observed in a subpopulation of anterior and intermediate pituitary lobe cells as well as in some nerve endings of the neurohypophysis. In the DES-induced ra...
