Fig. 1. Lactacystin-induced accumulation of parkin in the centrosome. SH-SY5Y cells
were treated without (-Lac; A-C) or with (+Lac, D-F) lactacystin, and
co-stained with antibodies against the centrosome marker
-tubulin
(
-tub; A,D) and parkin (PKN; B,E). Merged images (C,F) showed
significant accumulation of parkin in the centrosome after lactacystin
treatment (10 µM for 12 hours). The experiment was repeated three times
with similar results. Scale bars: 5 µm.
