Diminished tyrosine hydroxylase (TH) retinal expression in P84 APC^Min mice.

<p>(Panels A and B). TH immunostaining of eye sections of WT (A) and APC^Min mice (B), showing decreased TH in the sub retinal space of APC^Min mice. The nucleus was counterstained with 4, 6-diamidino-2-phenylindole (DAPI) (blue). C, Fifty micrograms of retinal protein was used for western blot analysis of TH. D, Protein levels were semiquantified with densitometry, normalized by β-actin levels, and compared between APC^Min mice and WT mice littermates (mean ± SD, n = 5), ** <i>P</i>< 0.01.
