title: Changes induced by fasting and cycloheximide in the vacuolar apparatus of rat hepatocytes. A morphometric investigation.
abstract: An increase in the number of autophagic vacuoles and in the size of the dense and residual bodies was observed in the hepatocytes of rats fasted for 24 hours; moreover, the number of dense bodies was reduced. These data suggest that the previously reported acceleration in cell protein degradation caused by fasting can be accounted for by enhanced autography. The treatment with cycloheximide, which was previously found to prevent this proteolytic response, also prevents the appearance of signs of enhanced autophagic activity.
