(A, left) The volumes of geminin-driven orthotopic tumors following expression of sh-control (black line, n = 10), shc-Abl (green line, n = 10) or sh-geminin (red line, n = 10) in Gem9 cells. All mice were kept on doxycycline containing drinking water throughout the experiment. A set of 10 mice were injected with Gem9 cells and kept on no doxycycline water (purple line). (A, right) Representative luciferase images taken at day 45 of tumors shown in (A, left). (B, left) The volumes of MDAMB231 orthotopic tumors following treatment with vehicle (black line, n = 10), imatinib (red line, n = 10) or nilotinib (green line, n = 10). (B, right) Representative luciferase images taken at day 12 of tumors shown in (B, left).
