EIF4A3 and hepatocellular carcinoma: To further explore the expression of EIF4A3 in HCC patients, an immunohistochemistry assay was conducted in 138 paired HCC tissues and revealed that the expression of EIF4A3 was higher in HCC tissues than in nontumor tissues (Fig. 3i-j) and that the expression of EIF4A3 and circTOLLIP was positively correlated in HCC patients (Fig. 3k).
