PRRX1 has been shown to be an EMT inducer in some kinds of cancers, but the role of PRRX1 in SACC remains unknown.19, 20 To examine the potential of PRRX1 to induce EMT in salivary adenoid cystic carcinoma, we applied the overexpressed lentiviral vector to transfect PRRX1 to salivary adenoid cystic carcinoma cells, SACC‐83 and SACC‐LM, which was confirmed by immunoblotting, real‐time PCR (Figure S2C). The gene discussed is PRRX1; the disease is cancer.
