Figure 3. Cyclin D3 Is Required for Maintenance of Notch1-ICD-driven T-ALL In Vivo.
(A) Schematic representation of the experimental design. After T-ALL formation in the recipient mice, cyclin D3 ablation was induced at six and a half weeks post BMT.
(B) Representative FACS analysis showing percentage of Notch1-ICD-overexpressing GFP+ cells in spleens right after completion of pI-pC administration (started 6.5 weeks post BMT) in cyclin D3F/F/Mx1-Cre+ (D3Δ/Δ) or D3F/F/Mx1-Cre− (D3F/F) mice. SSC, side scatter.
(C) Mean percentages of GFP+ cells in spleens in mice treated as in (B). Error bars, SD, n=4.
(D) Kaplan-Meier analysis of survival time in each group, n=6. See also Figure S3.
