PABPC1 and esophageal squamous cell carcinoma: In addition, PABPC1 expression was higher in eight ESCC cell lines (KYSE150, KYSE520, KYSE510, KYSE410, KYSE450, KYSE180, 81 T, and TE1) compared with an immortalized normal esophageal cell line (NE1), as detected by western blotting and qRT-PCR (Fig. 1G).
