Identification of a Novel Potential Biomarker in a Model of Hemorrhagic Shock and Valproic Acid Treatment1

HS causes an acute rise in serum claudin-3 protein levels and a concurrent decrease in intestinal claudin-3 protein expression. VPA treatment attenuates these alterations and stabilizes intestinal claudin-3 levels. Our results demonstrate for the first time that claudin-3 is a potential biomarker in HS and treatment.
