title: Establishment and characterization of 12S adenoviral E1A immortalized rat submandibular gland epithelial cells.
abstract: Rat submandibular gland (RSMG) cells have been immortalized with a retrovirus vector which encodes the adenovirus 12S E1A gene product. The immortalized cells were epithelial-like in nature and displayed a beta-adrenergic coupled rise in intracellular cAMP upon exposure to norepinephrine. Western- and lectin-blotting experiments of cell lysates demonstrated the presence of blood group A-reactive oligosaccharides. Such oligosaccharides are characteristic of RSMG mucin-glycoproteins. These cells appear to be suitable for use in analysis of cell-specific factors which regulate RSMG glycosylation.
