- Heat map showing the relative expression levels after drug treatment for 48 h in Panc1. Values measured by qRT–PCR were depicted with the software GENE-E. Only mocetinostat upregulated the miRNAs and downregulated ZEB1.
- Relative expression of indicated genes in Panc1 measured by qRT–PCR after treatment with different HDAC inhibitors. Note the downregulation of ZEB1 and upregulation of miR-203, miR-200, and E-cadherin by mocetinostat. n = 3, mean ± SEM; unpaired Student's t-test. For significance, see Supplementary Table S1.
- Immunoblot and immunofluorescence showing that mocetinostat treatment (1 μM, 48 h) reduced ZEB1 expression and induced E-cadherin in Panc1. Expression of histone deacetylases was not altered by mocetinostat, but histone acetylation was induced. Scale bar 10 μm.
- Chromatin immunoprecipitation analysis validated mocetinostat-induced (1 μM, 48 h) enrichment of the active histone marks H3ac, H4ac, H3K9ac, and H3K4me3 at ZEB1 target gene loci in Panc1. n = 3, mean ± SEM; unpaired Student's t-test.
- Mocetinostat treatment reduced expression of the anti-apoptotic miR-203 target survivin and sphere-forming capacity in Panc1 when pre-treated with mocetinostat for 48 h. n = 3, mean ± SEM; Mann–Whitney U-test.
