doi: 10.1073/pnas.1908353116
Figure Lengend Snippet: KRAS G13D CRC cells are sensitive to NF1-mediated GTP hydrolysis. (A) Total number of mutations per sample in KRAS G12- and G13-mutated COAD from TCGA cancer samples (P = 0.018). (B) Mutational burden comparing KRAS codon 12 and codon 13 mutations with mismatch repair mutations and microsatellite instability (MSI-H, MSI high; MSI-L, MSI low; MSS, MS stable) in TCGA COAD samples. (C) Comparison of NF1 mutations and KRAS mutation status in CCLE cell lines. Category sample sizes are indicated above each bar. (D) NF1 overexpression in HCT-116, a KRAS G13D/NF1-mutated cell line, leads to reduced KRAS-GTP levels.
