SALL4 and gastric cancer: SALL4 knockdown downregulates the expression of stemness- and EMT-related genes (OCT4, SOX2, NANOG, C-MYC and CD44) and suppresses the activation of the ERK, STAT3 and NF-κB pathways, thus inhibiting the proliferation and migration of gastric cancer cells (Yuan et al. 2016).
