Abstract:
PURPOSE: The objective of this study was to investigate the effects of (6)-gingerol, ginger components proliferation and adipocyte differentiation from early to lately steps. METHODS: 3T3-L1 preadipocytes were cultured. Differentiation of confluent cells was induced with dexamethasone, isobutylxanthin and insulin for 2 day and cells were cultured by medium with insulin in presence of various concentrations 0, 25, 50, 100 (micromol/L) of (6)-gingerol for 4 day. Cell viability was measured using the EZ Cytox assay kit. In addition, we examined the expression of mRNA levels associated with each adipocyte differentiation step by real time reverse transcription polymerase chain reaction. RESULTS: (6)-Gingerol inhibited adipocyte proliferation in a dose and time dependent manner. Expression of C/EBPbeta, associated with early differentiation step remained unchaged. However, intermmediate, late differentiation step and adipocytokines were effectively changed in dose-dependently manner in cell groups treated with (6)-gingerol. CONCLUSION: This study has shown that treatment with (6)-gingerol inhibited adipocyte proliferation as well as each adipocyte differentiation step. In particular, the (6)-gingerol more effectively inhibited adipocyte differentiation from intermmediate differentiation step.
