    Effect of tension-force on plasminogen activator activity from human periodontal ligament cells (1997)

    Notes: The plasminogen activator (PA)-plasmin proteolytic system has recently received considerable attention because of its participation in a wide variety of biological activities and in pathological conditions involving tissue destruction. Excessive mechanical stress such as occlusal trauma is associated with alveolar bone loss in severe periodontitis. Therefore, mechanical stress may involve degradation of the extracellular matrix by occlusal trauma through activation of the PA-plasmin proteolytic system. We examined the effects of mechanical stress on PA activity, gene expressions of tissue type (t) PA, urokinase type (u) PA and PA inhibitor-1 (PAI-1) in human PDL cells. Human PDL cells were cultured on flexible-bottomed culture plates and placed on a Flexercell Strain Unit. The cells were flexed at 6 cycles (5 s strain, 5 s relaxation) at 9% and 18% elongation for 5 d. Application of tension-force induced significantly higher PA activity in stressed PDL cells than in non-stressed controls, and did so in a time- and magnitude-dependent manner (p〈0.001, ANOVA). Western-blot analysis revealed that the high level of activity was due to tPA and not uPA. Gene expression of tPA mRNA in stressed PDL cells, as examined by RT-PCR, increased on d 5. These findings suggest that tPA may be involved in periodontal metabolism in response to mechanical stress.

    Collagen as the Major Edible Component of Jellyfish (Stomolophus nomural) (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 48 (1983), S. 0

    Notes: The mesogloea and skin of a common edible jellyfish, Stomolophus nomurai, were characterized with respect to amino acid composition and compared with a commercially salted jellyfish. Then the mesogloea was digested with pepsin at 3°C for 48 hr and its solubilized protein was isolated and subjected to biochemical analyses. These composite results have shown that the major edible component of jellyfish was the connective tissue protein, collagen, characterized by its high content of hydroxylysine and its glycosides.
