본 연구는 감마선을 이용한 육종 차조기 추출물을 통해 항염증 효능을 평가하고자 하였다. RAW 264.7 세포에서 MTT를 통해 세포 생존율을 평가하였으며, LPS로 유도한 RAW 264.7 세포에서 ROS, NO, 염증성 사이토카인, NF-κB, COX-2 등을 ELISA, Luminex 및 PCR로 측정하였다. 그 결과, 육종 차조기 추출물은 25 ㎍/㎖ 이하에서 세포독성이 없었으며, LPS로 유도된 RAW 264.7 세포에 서 ROS, NO, 사이토카인(IL-1β, IL-6, TNF-α)의 생성을 억제하였다. 또한, NF-κB, COX-2의 발현을 감소시켜 육종 차조기 추출물은 뛰어난 항염증 효과를 보였다. 이와 같은 결과는 염증 매개체로 인해 발생하는 질환을 개선하기 위한 새로운 건강식품 및 치료제의 원료로 개발될 수 있다.
The purpose of this study was to confirmed anti-inflammatory effect the apple Induced by mutants with γ-Ray extract. Cell viability was assessed by MTT assay using RAW 264.7 cells. The extracts measured through changes in the levels of reactive oxygen species (ROS), nitric oxide (NO), inflammatory cytokines, NF-kB, and COX-2 on LPS-induced RAW 264.7 cells. All test results were analyzed by ELISA reader, Luminex and RT-PCR. In result, the extracts was not toxic below in 25 ug/ml, and extracts was inhibited the productions nitric oxide, ROS, cytokines (IL-1b, IL-6, TNF-a), NF-kB and COX-2 in LPS-induced RAW 264.7 cells. Also, the expression levels were decreased on mRNA of NF-κB and COX-2. In other words, Perilla frutescens var. crispa Induced by mutants with γ-Ray extracts showed significant anti-inflammatory effect. These results may be developed as a raw material for new health food and therapeutics to ease the related to the above mediators.
