Abstract

The zinc-finger transcriptional repressor Snail1 affects cancer progression by controlling the epithelial cell-mesenchymal transition. The RNA-guided clustered regularly interspaced short palindromic (CRISPR) with a CRISPR-associated nuclease 9 (Cas9) nuclease system has been extensively used for gene editing. Here, we used two distinct sgRNAs to successfully target Snail1 in the gastric cancer cell line MGC803 with the CRISPR/Cas9 system. Furthermore, we discovered that Snail1 knockout reduced the proliferation and migration of MGC803 cells.
