title: Calmodulin content in different brain areas of aging rats.
abstract: An age-related decrease of calmodulin content was detected in the striatum, cerebral cortex and cerebellum of 3-, 22- and 30-month-old rats. This age-related decrease of calmodulin level occurred both in the supernatant and in the pellet fraction of high speed centrifuged tissues. However, the rates of age-dependent calmodulin loss in the pellet and supernatant fraction were differentiated according to the cerebral region considered, suggesting a different brain area sensitivity to the aging process.
