We review in this paper some reported data on age-dependent modification of proteins pointing out the relationship between the increase of nonenzymatic glycation in abdominal skin collagen of Wistar rats, evaluated by fluorescence intensity, and tendon breaking time, used as a parameter of collagen stiffness. Fluorescence intensity data linearly correlate with the breaking times of collagen fibers from Wistar rats reported from different sources, according to the hypothesis of a common etiological mechanism. It is possible to suppose that posttranslational modifications of proteins play a role in the tissue aging and their level in collagen may be used as a parameter for quantitation.

Abstract

We review in this paper some reported data on age-dependent modification of proteins pointing out the relationship between the increase of nonenzymatic glycation in abdominal skin collagen of Wistar rats, evaluated by fluorescence intensity, and tendon breaking time, used as a parameter of collagen stiffness. Fluorescence intensity data linearly correlate with the breaking times of collagen fibers from Wistar rats reported from different sources, according to the hypothesis of a common etiological mechanism. It is possible to suppose that posttranslational modifications of proteins play a role in the tissue aging and their level in collagen may be used as a parameter for quantitation.
