(L) Enrichment of RNA polymerase Ⅱ on SOX1 promoter region after Bufexamac treatment in V1-PAKI cells on day 16 of dorsal (left, p=0.0007 (V1-PAKI), p=0.0002 (+Buf)) and ventral (right, p=0.0083 (V1-PAKI), p=0.0276 (+Buf)) neural differentiation. Data information: Data are presented as mean ±SEM from three independent experiments (n=3). *p<0.05, **p<0.01, ***p<0.001 versus Ctrl group ; #p<0.05, ##p<0.01, ###p<0.001 versus V1-PAKI group ; (one-way ANOVA).
