EIF4A3 and bladder transitional cell carcinoma: Furthermore, qRT-PCR assay using BLCA cell lines and 22 paired BLCA samples, to verify the mRNA expression levels of EIF4A3 in BLCA, revealed that EIF4A3 expression was significantly elevated (p < 0.01) in 5,637, T24, and UM-UC-3 cells compared to the SV-HUC-1 cell line (Fig. 2A).
