Lapatinib in combination with AGK2/AK1 increase long term cell sensitivity compared to Lapatinib alone. a 5-8F and 6-10B cells were seeded in 6-well plates and treated with the Lapatinib concentration indicated for 72 h. Five micromolar AGK2 and AK1 was used for combination treatment. Cell culture media was then removed and colony formation observed for 15 days. At the end of this time period, cells were fixed with 4% paraformaldehyde and stained with crystal violet. Representative pictures from triplicate experiments are shown. b The stain was solubilised with 33% acetic acid and absorbance at 592 nm were obtained. Graphs were generated to show the effect of combination treatment. c Best fit-curves were generated to determine the effect of AGK2/AK1 on the IC50 of Lapatinib in 5-8F and 6-10B cells.
