- Abstract
- This study was conducted to evaluate the fractions isolated from Allomyrina dichotoma larva
extract (ADLE) that exhibited anti-apoptotic and anti-inflammatory effects. A total of 13 fractions
were eluted from ADLE by centrifugal chromatography (CPC), and the polar AF-13 fraction was
selected, which exerted a relatively protective effect against fat-induced toxicity in INS-1 cells. AF-13
treatment of palmitate-treated INS-1 cells decreased the expression level of apoptosis-related proteins
and DNA fragmentation. AF-13 also significantly inhibited the production of nitric oxide and reactive
oxygen species and the triglyceride content induced by palmitate, and the effect was found to be
similar to that with ADLE treatment. Palmitate upregulated the expression of cyclooxygenase-2
(COX-2) and inducible nitric oxide synthase (iNOS) through the activation of NF-κB p65; however,
this effect was significantly attenuated by AF-13 treatment. In conclusion, AF-13 is one of the major
components of ADLE responsible for anti-apoptotic and anti-inflammatory activities.
