IGF1R levels in the brain negatively correlate with longevity in 16 rodent species
Figure 4. Levels of IGF1R protein in heart tissue do not correlate with lifespan or body mass. (A) Western blots showing IGF1R and actin bands. (B) Log-transformed graph of IGF1R intensity plotted against maximum lifespan shows no correlation. (C) Log-transformed graph of IGF1R intensity plotted against average adult body mass shows no correlation. Error bars are s.d.
