  • Title: A comparision of normal submaxillary gland proteins with proteins obtained from a transplantable murine salivary gland carcinoma (myoepithelioma).
    Author: Irwin D, Malamud D.
    Journal: Cell Biol Int Rep; 1979 Jan; 3(1):75-84. PubMed ID: 222488.
    Abstract:
    A new transplantable murine salivary gland carcinoma (myoepithelioma) was further characterized by comparing total protein patterns with normal submaxillary gland proteins. Analysis by isoelectric focussing or by labelling studies with radioactive leucine showed considerable differences between tumour and normal proteins. In contrast, analysis of staining patterns after electrophoresis in sodium dodecyl sulphate containing gels revealed a striking similarity between normal proteins, tumour proteins and proteins obtained from metastatic growths. It thus appears that tumour proteins closely resemble the normal proteins from the tissue of origin with respect to molecular size as determined by electrophoretic mobility, while significant differences occur in charge and labelling kinetics.
