Functional maintenance of liver is very important at all times for personal health. Hsp induction is associated with the protection of the organ. Glutamine, a nutrient inducer of Hsps, enhances cellular survival via Hsp72 induction in several organs, but not in the liver. The present study showed a novel approach to facilitate glutamine-induced hepatic Hsp72 synthesis and its possible mechanisms were discussed. ⋯ Glutamine switched on alteration pathway in inducing hsp72 gene activation. The existence of Hsp72 plays a critical role in the reactivation of hsp72 gene. Glutamine sustained the induction of intracellular Hsp72, which could be beneficial in protecting the liver from various injuries.
