MAS1 has been reported to counteract AGTR1‐mediated cancer development and metastasis.[15] We therefore examined the effects of saMAS1/AD on cell motility using a wound‐healing assay in two ovarian cancer cell lines (A2780 and OVCA429) treated with all three identified saRNAs, respectively, delivered by AD. This evidence concerns the gene AGTR1 and ovarian cancer.
