Fig. 4. AtRA induces p27 nuclear accumulation by reducing p27 serine-10 phosphorylation.

(a) Kinetic analyses of relevant endogenous components, as well as loading and fractionation controls, in the whole cells (the upper group), the nuclear fractions (the middle group) and the cytosolic fractions (the lower group) of atRA-treated ESC. (b) Silencing CRABPI abolished atRA-triggered elevation in P27 levels, and, consistently, decreased the p-S10-P27 levels. Silencing and loading controls were shown at the two lower panels.
