JNK expression in polarized and non-polarized RPE cells.

<p>A: Immunofluorescein staining for phospho-c-Jun. In controls, immunohistochemistry shows that phospho-c-Jun is expressed more strongly in polarized RPE cells than that in non-polarized RPE cells. B: Western blot shows that phospho-JNK and phospho-c-Jun are expressed more strongly in polarized RPE than non-polarized RPE. JNK is expressed comparably in both types of RPE cells.
