Investigating how starvation and diabetes alter pyruvate dehydrogenase kinase levels in rats, suggesting potential therapeutic targets.

The study aims to examine how starvation and diabetes affect the levels of pyruvate dehydrogenase kinase isoenzymes in rat hearts.
Immunoblot analysis was used to measure PDK isoenzyme levels in the rat heart.
Experimental diabetes was induced using streptozotocin, and starvation conditions were applied.
Re-feeding and insulin treatment were implemented to assess their effect on PDK levels.
Starvation and diabetes significantly increased PDK4 protein levels and mRNA abundance.
Re-feeding and insulin treatment reversed the increases in PDK4, restoring enzyme activity to control levels.
No significant changes were observed in PDK1 and PDK2 levels in response to starvation and diabetes.

Wu et al. (1998) studied this question.
