In another study, asiatic acid increased protein and mRNA expression levels of E‐cadherin, and reduced expression levels of N‐cadherin, snail family transcriptional repressor (Snail) and β‐catenin in A549 cells treated with TGF‐β1, hence inhibiting TGF‐β1‐induced EMT in lung cancer.119. This evidence concerns the gene TGFB1 and lung cancer.
