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. Here, ROBO1 is linked to gastric cancer.
