Fig. 3. Whereas the tight junctional protein occludin was transcriptionally downregulated following Snail expression, claudin-1 and ZO-1 were not. The mRNA expression levels of junctional proteins were detected by RT-PCR/Southern blot analysis using the indicated probes. While the expression of the
(+) ZO-1 isoform was not changed in each cell, the
(-) isoform expression levels were elevated in two Snail-expressing cells.
