Micheliolide(MCL) is a sesquiterpene lactone which inhibits various inflammatory response.

BV2 cells were pretreated with the indicated concentrations of Micheliolide?1 h prior to stimulation with LPS (1 μg/ml) for 6 h and total RNA was extracted using RaPure Total?RNA Kit.Reverse transcription was performed using RevertAid First Strand cDNA Synthesis Kit.?Real-time PCR analysis was performed using SYBR Select Master Mix ?in conjunction with an ABI Prism 7500 Sequence Detection System with the expression of β-actin as the internal control.?The data were analyzed using the ΔΔCT method.?The primers for iNOS, COX-2, TNF-α, IL-1β, IL-6 and β-actin were described as below.
