Age related modifications of soluble proteins in various organs of male garden lizard, Calotes versicolor.
The oxidative modification of proteins measured as carbonyl derivatives increased with advancing age in the liver of male garden lizard. The same parameter did not show a significant change in other organs (brain, heart and kidney). Based on the observations in both homeotherms (mammals) and poikilotherms (insect and reptile), the in vivo oxidative modification of cellular proteins appears to be the most common mechanism leading to accumulation of altered proteins during aging. However, the degree of modifications may vary among the tissues/organs of a species. On the other hand the variations may also account for the role of modification of proteins in the pattern of aging in different species.
