Objectives: The aim of this study was to observe the reduction of lipid accumulation by treatment with Akkermansia muciniphila extract on 3T3-L1 adipocytes. Methods: After treating pasteurized Akk. muciniphila strains in HT-29 colorectal cancer cell, the relative expression of interleukin (IL)-8, tumor necrosis factor-α, IL-6, and IL-1β mRNA was analyzed by real time polymerase chain reaction, respectively. 27 strains of Akk. muciniphila which have anti-inflammatory effects were selected. 3T3-L1 pre-adipocytes were treated with Akk. muciniphila for 24 hr and then measured the toxicity using water soluble tetrazolium salt assay. The cells were incubated for 4 days and then differentiated into adipocytes using the medium including adipogenic reagents for 10 days. The Akk. muciniphila was treated when the medium was exchanged for differentiation medium at 4th day and insulin medium at 6th day. To observe the lipid accumulation, the cells were stained with Oil red O dye and were measured using a spectrophotometer. Results: In the cytotoxicity test, the cell viability of 3T3-L1 pre-adipocytes was significantly increased compared to the control group which untreated with Akk. muciniphila, and there was no cytotoxicity of Akk. muciniphila at 1×107 CFU/mL. The results on Oil red O staining and absorbance measurements were showed a significant decrease in lipid accumulation in the group which was treated with Akk. muciniphila compared to the control group. Conclusions: In our results, Akk. muciniphila has the inhibitory effect of lipid accumulation in 3T3-L1 adipocytes. This suggests that Akk. muciniphila could be help to improve obesity.
