Wang et al. found that exosomal miR-155-5p secreted by paclitaxel-resistant GC cells could induce epithelial-mesenchymal transition and chemotherapeutic resistance in paclitaxel-sensitive GC cells by suppressing GATA binding protein 3 and tumor protein p53 inducible nuclear protein 1 expression 93. This evidence concerns the gene GATA3 and gastric cancer.
