Expression of GDNF and NTN mRNA and that of the receptors c-Ret and GFRα-1 in the muscularis externa of 6 month AL-fed rats (6AL, n = 3) and 24 month CR rats (24CR, n = 3) and 24 AL-fed rats (24AL, n = 7). Expression of β-actin was used for external standardisation. A negative control (C) was run, in which the RT enzyme was omitted. M = molecular markers.
