Levels of IGF1R protein in lung 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 very weak (non-significant) correlation (r²=0.05). (C) Log-transformed graph of IGF1R intensity plotted against average adult body mass show very weak (non-significant) correlation (r²=0.18, p=0.11). Error bars are s.d.
