ZFR and gastric cancer: Moreover, exosomes can transfer circRNAs to control TMZ resistance in glioma, such as circRNA nuclear factor I X (circNFIX) and homeodomain interacting protein kinase 3 (circHIPK3), [9, 10].CircRNA hsa_circ_0072083 (circ_0072083) is derived from zinc finger RNA binding protein (ZFR), which may play a promoting or suppressive role in human tumors, such as gastric cancer and papillary thyroid cancer [11, 12].
