Wang et al. found that the expression of LINC01559 is upregulated in mesenchymal stem cells (MSCs) compared with that in GC cells, and then exosomes from MSCs can transfer LINC01559 into GC cells to promote the cell progression by activating the PI3K/AKT signaling pathway (Wang et al., 2020). This evidence concerns the gene AKT1 and gastric cancer.
