Fold alterations in p21 promoter activation, p21 mRNA stability, p21 protein stability, and p21 protein levels following MAPK activation

Variable	-Fold alteration, 8 h after MAPK activation	-Fold alteration, 36 h after MAPK activation
MAPK activation	10-fold	9-fold
p21 full-length −2326 promoter activation	6-fold	9-fold
p21 mRNA stabilization	4-fold	10-fold
p21 protein stabilization	2.5-fold	2.5-fold
p21 protein expression	5-fold	13-fold

The -fold increases in p21 promoter activation, p21 mRNA stability, p21 protein stability, and p21 protein levels were derived from data presented in Figures 1–9.
