Abstract: BACKGROUND: Although some amino acids are recognized to have favorable effects on the liver regeneration after partial hepatectomy (PH), molecular mechanisms underlying these effects are barely known.
OBJECTIVE: Our study was aimed to investigate the effects of valine, glutamine, and leucine amino acids on PH-induced NF-κB signal pathway. The research team studied Leucine in a rat model in vivo. The study took place in the medical and surgical experimental research center at the Eskisehir Osmangazi University in Eskisehir, Turkey. The animals were Wistar albino male rats.
RESULTS: Group I, the sham group, was administered phosphate buffered saline (PBS) after laparotomy. After 70 % PH procedure, group II, III, IV, and V received single intraperitoneal doses of PBS, valine, glutamine, and leucine amino acids, respectively. At hour 6 after PH, expressions of 88 genes involving in NF-κB signal pathway were examined by RT-PCR mini array method in the liver tissue specimen. Fold values below 0.5 and above 2 were regarded as significant.
CONCLUSIONS: Our results suggested that valine, glutamine, and leucine amino acids may alter expressions of the genes of NF-κB signal pathway. In addition, among these amino acids, glutamine and valine proved to be much more effective on NF-κB signal pathway after the PH (Tab. 1, Ref. 41).
