EIF3F and cancer: We have previously studied a MPN protein CSN subunit 6 and found that it is involved in cancer growth.[8, 20] To further investigate another MPN domain‐containing protein, eIF3f, in CRC, we examined the status of eIF3f in the TCGA‐COAD database firstly, and found that eIF3f is overexpressed in CRC compared with normal tissues (Figure1A).
