ZEB1 and adenocarcinoma: Treatment of a partial EMT adenocarcinoma cell line A549 with sodium acetate (SA), sodium propionate (SP) and sodium butanoate (SB) showed a drastic increase in the key epithelial gene marker E‐cadherin, with a decrease in the mesenchymal master regulator ZEB1 for propionate and butanoate, but not for acetate (Fig 2A–C), in line with the genomic analysis.
