지방세포 3T3-L1과 대장암세포 SW-480에서 메밀 성분인 rutin의 항염증 효과

Purpose: The objective of this study was conducted to investigate the effects of rutin, buckwheat components on cell growth and anti-inflammation in adipocyte 3T3-L1 and human colon cancer cell SW-480. Methods: We cultured 3T3-L1 adipocyte and SW-480 colon cancer cell to confluence, at which time starvation was induced with SFM for 1 day. Cells were then cultured in medium containing 0, 25, 50, or 100 μmol/mL of rutin 3T3-L1 or 0, 10, 20, or 40 μmol/mL SW-480. Cell viability was measured using a cell viability kit. In addition, we examined the expression of mRNA related to inflammation. RT-PCR was used to quantity tumor necrosis factor (TNF-α), interleukin-1β (IL-1β), IL-6, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) mRNA levels. Results: Rutin significantly inhibited 3T3-L1 and SW-480 cell proliferation in a dose and time dependent manner. Rutin also significantly reduced the mRNA expression of IL-1β, IL-6 and TNF-α at the highest dose. In addition, rutin treatment caused a significant reduction in COX-2 and iNOS mRNA levels compared to the control group. Conclusion: Overall, our results suggest that rutin has the potential to reduce inflammation, and that these effects are greater during tissue-damaging inflammatory conditions.
