A) Daoy and Med1-MB cells were stably transduced with YFP, YFP-CK2α, or YFP-CK2β. B) left- Cell growth of Daoy cell lines transduced with YFP-CK2α or YFP-CK2β. right– Cell growth of transduced Med1-MB cells. Bars represent mean of three technical or experimental replicates, mean±SD, student t-test. C) Soft agar analysis of Daoy and Med1-MB expressing YFP-CK2α or YFP-CK2β. Bars represent mean of three technical or experimental replicates, mean±SD, student t-test. D) Survival curve of mice intracranially injected with transduced Daoy cell lines. N = 5 mice per treatment and experiment was done in duplicate. Log-rank was used to determine p value. E) Tumors from mice counted for number of Ki67 positive cells. Bars represent mean of three technical or experimental replicates, mean±SD, student t-test. *p < 0.05, sample compared to control cells.
