Figure 2. CASZ1 regulates the levels of proteins that regulate G₁–S phase cell cycle progression. (A) The protein levels of cyclins in SY5Y cells upon CASZ1a induction were visualized by immunobloting whole-cell lysate with indicated antibodies. (B) The protein levels of Cdks in SY5Y cells upon CASZ1 induction were visualized by immunobloting whole-cell lysate with indicated antibodies. The relative densitometric units were normalized to control condition and the ratio shown under each condition. (C) The protein levels of Cdk inhibitors in SY5Y cells were visualized by immunobloting whole-cell lysate with indicated antibodies. (D) The protein levels of cell cycle regulators in NGP cells were visualized by immunobloting whole-cell lysate with indicated antibodies.
