Yao et al. demonstrated that nasopharyngeal cancer cells-associated exosomal RNA TP73-AS1 increased NPC proliferation by sponging miR-342-3p and also supported pro-tumor M2 polarisation of TAMs via transfer through exosomes as witnessed by increment of M2 markers like CD206 and MRC-2 in control macrophage cells when co-cultured with TP73-AS1 overexpressing CNE-2 cells (Yao et al., 2022). Here, TP73 is linked to nasopharyngeal carcinoma.
