Secretory Protein Synthesis in the Stimulated Rat Parotid Gland
Administration of the beta-adrenergic drug, isoproterenol (IPR), affects the release of 98% of stored amylase from rat parotid gland acinar cells. A period of 6 h elapses from the onset of secretion to the maximum [(14)C]phenylalanine (Phe) incorporation into total protein and amylase. 10 h after IPR administration the rate of [(14)C]Phe incorporation into total protein was no longer elevated a...
متن کاملConcomitant Synthesis of Membrane Protein and Exportable Protein of the Secretory Granule in Rat Parotid Gland
After enzyme secretion the membrane of the secretory granule, which had been fused to the cell membrane, was resorbed into the cell. Experiments were therefore carried out to test whether formation of new secretory granules involves reutilization of the resorbed membrane or synthesis of a new membrane, de novo, from amino acids. Incorporation of amino acids-(14)C into proteins of various cell f...

متن کاملSclerosing Mucoepidermoid Carcinoma of the Parotid Gland
Introduction: Mucoepidermoid carcinoma represents one of the most common malignant salivary gland tumors.However, the sclerosing morphologic variant is extremely rare with only 23 reported cases in the English-language literature since it was discovered in 1987. Case Report: Herein, we describe another case that was diagnosed in a 25-year-old woman presenting with a posterior auricular mass, ...
متن کاملNerve-acinar Cell Relationships in the Rat Parotid Gland
Ultrastructural studies have shown that many exocrine glands receive their autonomic innervation through close (180-250 A) apposition of the nerve and acinar cell membranes (1, 5, 14, 16, 17, 20, 23-25). The nerve terminations or varicosities often lie in a groove on the surface of the acinar cell, or are closely apposed to two or more acinar cells by lying in the intercellular space between th...
