To further study the role and mechanism of UTP14A in tumour metastasis by in vitro experiments, we tested the protein and mRNA expression of UTP14A in several commonly used ESCC cell lines, among which KYSE-150 cells and Eca109 cells had relatively higher expression (Fig. 1F, G). The gene discussed is UTP14A; the disease is esophageal squamous cell carcinoma.
