Supplementary Figure S1. Generation of GEMM-derived cell lines. Supplementary Figure S2. QPCR and Western blot analyses of DTYMK expression in 634 cells upon indicated shDtymks transduction. Supplementary Figure S3. Lkb1-wt 634 and Lkb1-null t4 cells transduced with shGFP, shDtymk-1 or shDtymk-3 and then cultured with or without additional 100 microM dTTP in medium for 4 days. Supplementary Figure S4. Lkb1-wt (634, 855, and 857) and Lkb1-null (t2, t4, and t5) cell lines (A) and human LKB1-wt (H358 and Calu-1) and LKB1-deficient H2122 and A549) NSCLC cell lines (B) were treated with CHEK1 inhibitors, AZD7762 and CHIR124, for the indicated dose and time, and then lysed for Western blot analysis of gammaH2AX. Supplementary Figure S5. Immunohistochemical analyses assessing gammaH2AZ. Supplementary Figure S6. QPCR and Western blot analyses of DTYMK expression in LKB1-wt Calu-1 NSCLC cells.
