ATG2A and neoplasm: EVs derived from hUC-MSCs, enriched with miR-13896 by electroporation, were shown to specifically target tumor sites and suppress gastric cancer progression by downregulating the autophagy-related gene Autophagy-related protein 2 homolog A (ATG2A), thus inhibiting tumor cell proliferation and metastasis both in vitro and in vivo [56].
