SLIT2 and gastric cancer: For example, it was reported that POU2F2 promotes GC metastasis through a positive regulation of Robo1,19 whereas another study showed that down‐regulating Slit2 increases growth and motility of GC cells by activating AKT/β‐catenin.17 In our study, we clearly demonstrate the downregulation of Slit2 and Robo1 expression in multiple datasets and our samples at both mRNA and protein levels.
