TFF3 and neoplasm: Other studies reported on the effects of exosomal miRNA that decreased tumor growth were associated with NF-κB p65 activation [30], downregulation of VEGF expression [31], inhibition of Galectin-3 [32], regulation of KDM4B/HOXC4/PD-L1 axis [33], down-regulation of mTOR and S6KB1 expression [34], and down-regulation of trefoil factor 3 (TFF3) [35].
