Abstract |
We investigated whether a taurine-ribose derivative, N-(D-ribopyranosyl)taurine sodium salt, inhibits the differentiation process of preadipocytes or modulates the expression of cytokines from adipocytes as does taurine chloramine (TauCl) in vitro. To know the inhibitory effects of taurine-ribose (Tau-Ribose) on differentiation process and adipokine expression, preadipocytes were incubated with Tau-Ribose in differentiation medium for 14 days. Differentiated adipocytes were also stimulated at the concentration of IL-1β 1 ng/ml with addition of Tau-Ribose. After 7 days of incubation, the levels of adiponectin, leptin, IL-6, and IL-8 were measured from the culture supernatants. At concentrations of 10-40 mM, Tau-Ribose dose-dependently inhibited the process of adipogenesis. The treatment of Tau-Ribose decreased the expression of transcription factors, which are necessary for adipogenesis and are known as adipocyte marker. Treatment with Tau-Ribose significantly modulated the production of IL-8 and IL-6. However, it did not modulate the production of adiponectin and leptin in IL-1β-activated adipocytes. As with taurine chloramine, Tau-Ribose also inhibited STAT-3 signaling, independent of MAPK signaling. In conclusion, Tau-Ribose inhibits the signaling pathway of STAT-3 and can change adipokines production; thus, it may have a potential as an agent for treating obesity-related diseases. |
