Fig. 6: ZEB1 accelerates retrograde vesicular trafficking.

a Single-channel and merged confocal micrographs taken 1 h after initiating Alexa 488-labeled cholera toxin B (CTxB) treatment. Boxed areas are magnified (insets) to show greater CTxB co-localization with Golgi in 393P_ZEB1 cells than 393P_vector cells. Scale bars: 5 µm, 1 µm (inset). b Fraction of total CTxB that co-localizes with GM130, a Golgi marker, in each cell (dot). n = 42 cells from 3 independent experiments. Data are presented as mean values ± SEM; P values, two-tailed Student’s t test.
