YAP1 and gastric cancer: Overexpression of exosomal circ-PVT1 induces low expression of miR-30a-5p and high expression of YAP1 in GC cells.106 Circ29 packaged in exosomes can be transferred from GC cells to ECs and promote proliferation, migration, and tube formation of ECs by targeting the miR-29a/VEGF pathway.317 In addition, circNHSL1 is highly expressed in exosomes released from GC cells.
