Inhibition of hyperphosphorylation of Tau and NF proteins in motor neurons of TetraTg mice. (A) Hyperphosphorylated NF and tau protein levels were analyzed by western blot analyses and quantification of anti-Neurofilament M (n = 6), (C) anti-160 kD Neurofilament H (n = 6) spinal cord and using AT8, (G) brain, (E and F) spinal cord and PHF1 antibodies, (I) brain, (K) spinal cord. Quantification of immunoblots in by densitometric scanning B, D, H, J and I (**P < 0.001, ***P < 0.0001).
