Abstract

We have recently discovered that mycelium of Phellinus linteus, popular medical mushrooms in Korea, possess alcohol dehydrogenase and produce alcohol. In the present study, it was examined that the effect of fermented rice wine made by using mycelium of P. linteus (FLMP) on the expression of in-flammation-related proteins in both $HepG_2$ cells and rats. To examine the effect of FLMP on the morphology and expression of inflammatory proteins in $HepG_2$ cells, the cells were incubated with ethanol, and FLMP for 24 hours, and then analyzed by microscopic observation and Western blot and reverse transcription polymerase chain reaction (RT-PCR). While ethanol induced the morphological change accompanied with cell debris formation and scattering on $HepG_2$ cells, FLMP had no effect. The results of Western blot and RT-PCR analyses showed that the level of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-1 and COX-2 was induced by ethanol, however, FLMP inhibited the expression of these proteins and its mRNAs. In the animal model, the value of flutamate oxaloacetate transaminase and glutamate pyruvate transaminase was significantly increased by administration with ethanol. But the group administrated with FLMP showed lower levels on the changes of these markers compared with ethanol-administrated group. Besides, the results of Western blot and RT-PCR analyses showed that the expression of inflammatory proteins such as iNOS, COX-1 and COX-2 was not affected by FLMP administration in rat liver. About histopathological and immunohistochemical observations, inflammatory loci were markedly decreased in the FLMP-administrated rat compared to ethanol-administrated rats and showed weaker COX-2 and iNOS jmmunoreactions. These results suggested that FLMP showed slight changes on the inflammatory proteins expression compared to ethanol and FLMP may be used as a functional alcoholic beverage.

상황버섯균사체를 이용한 발효주 (FMLP)가 인체간암세포와 횐쥐 간에서 염증관련단백질의 발현과 간 손상관련효소에 미치는 영향에 대해 조사하였다. 에탄올, FLMP를 인체 간암세포인 $HepG_2$세포에 24시간 처리한 경우, 대조군에 비해 에탄올을 처리한 세포는 농도가 증가할수록 세포의 형태 변화가 심한 반면 FLMP를 처리한 세포는 알코올의 농도가 증가해도 세포의 형태 변화를 관찰할 수 없었다. $HepG_2$세포의 염증 관련 단백질 발현을 보기 위해 Western blot과 RT-PCR을 한 결과 COX-1, COX-2, iNOS, $TNF-\alpha$의 발현이 에탄올에 의해 현저하게 유도되었으나, FLMP는 $HepG_2$세포에서 mRNA와 단백질의 발현이 에탄올에 비해 억제되었다. 흰쥐를 이용한 동물실험에서 간 기능의 지표가 되는 혈청내 GOT와 GPT양 등이 에탄을 투여 그룹에서 현저히 증가했으나 FLMP를 투여한 그룹에서 에탄을 투여 그룹에 비해 낮게 나타났다. 면역조직화학적 분석에서 에탄올을 투여한 쥐의 간세포에서 iNOS와 COX-2의 발현이 현저히 증가하나 FLMP를 투여한 쥐의 간세포에서 미약한 면역반응이 관찰되었다. 이상의 결과로 보아 FLMP는 동일한 농도의 에탄올에 비하여 간 손상의 가능성이 적은 것으로 사료되며 이 자료들은 상황버섯에 대한 연구와 다른 기능성 주류에 대한 기초 자료가 될 것이다.
