Figure EV2. CDK2 genetic depletion increased endogenous levels of NICD in HEK293T cells.
- CDK2−/− HEK293T cells, lacking endogenous CDK2, were cultured for 48 h after seeding followed by Western blot for NICD, CDK2, CDK1 and CDK8. β‐Actin served as loading control.
- Quantification of the density of Western blot bands in (A) using ImageJ software. Data are expressed as fold changes compared to WT cells. All data represent the mean ± SEM from three independent experiments. Student's t‐test analysis was performed, with *P ≤ 0.05.
- CDK2−/− HEK293T cells were cultured for 48 h after transfection with plasmids encoding scrambled siRNA (−) or siRNA specific for CDK1 (+) followed by Western blot for NICD, CDK2, CDK1 and CDK8. β‐Actin served as loading control.
- Quantification of the density of Western blot bands in (C) using ImageJ software. Data are expressed as fold changes comparing WT cells (−/+ CDK1 siRNA) and CDK2−/− cells (−/+ CDK1 siRNA). All data represent the mean ± SEM from three independent experiments. Student's t‐test analysis was performed, with *P ≤ 0.05 and ***P ≤ 0.001.
