Effect of circadian on the activities of ion transport ATPases and histological structure of kidneys in mice

Abstract EN

The impacts of unnatural every day cycles (circadian) for 60 days on the histological structure of kidneys and ATPase activities in MF1 mice were studied.

The exposure times were 16 h dark, 16 h light, 24 h dark, and 24 h light, and control exposure times were 12 h dark followed by 12 h light.

Our results showed an increase in the total ATPase activity of mice in all groups.

Additionally, the activity of the enzyme Na+/K+- ATPase was increased after 24 h darkness, 24 h light, and 16 h light exposures compared to control.

The enzyme Mg+2-ATPase activities of the groups were higher when exposed to 16 h light, 24 h light, 24 h darkness and 16 h darkness.

The activities of total ATPase, Na+/K+-ATPase and Mg+2-ATPase in kidneys were increased in all groups after 24 h light, 24 h darkness, 16 h darkness and 16 h light exposures.

Interestingly, the activity of V-type ATPase was reduced after 16 h darkness, 24 h darkness and 16 h light.

Taking everything into account, changes in the day by day cycle prompt neurotic changes, enzymatic and histological changes in the kidneys of mice.
