Figure Lengend Snippet: ( a ) Representative examples of H&E, Glut1 or Glut3 staining by IHC from serial sections of a KP tumor showing Glut1-3 co-localization. Scale bars: 200 μm. ( b ) Histogram with mean ± s.d. shows the average number of KP and KPG1G3 tumors per mouse (n = 4 and 6 mice). *: p < 0.05 by Mann-Whitney test. ( c ) Graph with mean ± s.e.m. shows the fold changes of KP and KPG1G3 tumor volumes (n = 8 and 9 tumors) monitored during 43 days by μCT, starting at 15 weeks and 2 days post-tumor initiation with tumor volumes set to 1. ns: not significant by Mann-Whitney test; *: p < 0.05 by Mann-Whitney test. ( d ) Dot plot with mean ± s.d. shows tumor areas in KP and KPG1G3 mice (n = 115 and 101 tumors) calculated from lung sections. **: p < 0.01 by Mann-Whitney test. ( e ) Dot plot with mean ± s.d. shows KP and KPG1G3 tumor weights (n = 8 and 9 tumors, respectively) at sacrifice. **: p < 0.01 by Mann-Whitney test. ( f ) Percent of KP (n = 150) and KPG1G3 (n = 170) lesions classified by tumor grades, either detailed from alveolar hyperplasia (AH) to grade 5 or discriminated between alveolar hyperplasia and adenomas, and adenocarcinomas. Alveolar hyperplasia and adenomas include the AH and the tumor grades 1, 2, and 3. Adenocarcinomas contain the tumor grades 4 and 5. *: p < 0.05; **: p < 0.01. Fisher test was applied when comparing AH, grade 1, grade 2, grade 3, grade 4, and grade 5. Chi-square for trend was applied when comparing alveolar hyperplasia and adenomas, and adenocarcinomas. ( g ) Kaplan-Meier survival analysis of KP (n = 8) and KPG1G3 (n = 6) mice. *: p < 0.05 by Log-rank test. ( h ) Representative (upper panels) positron emission tomography (PET) scan and (lower panels) μCT scan images illustrating the 18 F-FDG absorption of KP, KPG1, KPG3 and KPG1G3 tumors. ( i ) Dot plot with mean ± s.d. displays maximum standardized uptake value (SUV max ) of KP (n = 17), KPG1 (n = 24), KPG3 (n = 32) and KPG1G3 (n = 38) lesions. ns: not significant by Mann-Whitney test; ****: p < 0.0001 by Mann-Whitney test. ( j ) Model illustrating the dependency on glucose transporters for KP and KL tumor progression. Figure 4—source data 1. Source files for tumor growth, grades and survival of KP and KPG1G3 mice.
