Figure 2. LKB1 deletion leads to genome instability. (A) Alpha-tubulin staining of proliferating LKB1-WT and LKB1-null cells. (B) DAPI staining showing increased multinucleation in LKB1-null cells. (C) DAPI staining showing increased micronucleation in LKB1-null cells. (D) Quantification of mitotic index in LKB1-WT and LKB1-null cells.
