Mammary tumor volume in MTB-IGFIR, MTB-IGFIR/Akt1
mice. Graphs showing tumor volumes in (A) MTB-IGFIR/Akt1−/− mice (red squares, red lines; n=6) compared to MTB-IGFIR mice (black circles, black lines; n=11) and (B) MTB-IGFIR/Akt2−/− mice (green diamonds, green lines; n=6) compared to MTB-IGFIR mice (black circles, black lines; n=11). Tumor volumes for each mouse were plotted as a scatter plot and the best fit, exponential line was drawn. The same group of MTB-IGFIR mice were used for both comparisons.
