mRNA levels under the treatment with diacerein in different experimental conditions are presented relative to the untreated control group calculated by the equation E-ΔCt (Mean ± SD, n = 9; value of 1 represents average level of mRNA expression in untreated control group). [c]1, low concentration of diacerein (5 μM); [c]2, high concentration of diacerein (50 μM).
