This table presents the increase or decrease rates of the transcript levels during the treatment kinetics, compared with the T₀ value. 0, Variation less than 2-fold. ⁺, Increase; –, decrease; (n), n-fold increase or decrease. More than 2-fold variations are shown in bold. Variations concerning very low expressed genes, such as SUP, may not be significant.
