  • Title: Age-related changes in the cellular level of amylase and protein synthesis in the rat parotid gland.
    Author: Kim SK.
    Journal: J Dent Res; 1981 Mar; 60(3):738-47. PubMed ID: 6162871.
    Abstract:
    Age-related changes in the cellular content of secretory proteins and protein synthesis were studied in parotid glands of rats of various ages. The secretory protein content (determined by measuring the level of alpha-amylase activity) and the synthesis of proteins (assayed by the rate of incorporation of 3H-leucine into acid-insoluble proteins) decline with increasing age. Morphological and radioautographic studies of the gland indicate that the decline in protein synthesis is due to the reduction in the ability of secretory cells to synthesize proteins.
