Effects of astragaloside IV on the changes in retina protein.

<p>p-ERK/ERK ratio (left) and NF-κB (right) expression in retina protein determined by Western blot. Upper panels are the representative immunoblots of proteins in this area. Bottom graphs show the mean p-ERK/ERK ratio or densitometric quantification of the corresponding bands. GAPDH or Histone3 was used as a loading control. The mean for proteins in db/m mice (LC group) retina was set at 100%. A. p-ERK/ERK ratio: NC vs. LC, p = 0.038. * p<0.05; AL, AH vs NC, p = 0.126, 0.025 respectively. n = 3, # p<0.05). B. NF-κB: NC vs. LC, p = 0.001. ** p<0.01; AL, AH vs. NC, p = 0.001, 0.004 respectively. n = 3, ## p<0.01).
