Figure 3. Cdk6 and p21 were regulated by CASZ1a shortly after CASZ1 restoration. The protein levels of cell cycle regulators in SY5Y cells (A) and NGP cells (B) were visualized by immunobloting whole-cell lysate with indicated antibody from 8–24 h after induction of CASZ1a. The relative densitometric units were normalized to timed control, and the ratio shown under each condition.
