Eukaryotic translation initiation factor 3, subunit H (EIF3H) is a subunit of EIF3, which is involved in mRNA recruitment and ribosomal complex disassembly and is known to be a driver of cell proliferation and survival in cancer.
These findings uncover a mechanism of translation control that is based on mRNA looping and identify METTL3-eIF3h as a potential therapeutic target for patients with cancer.
The effect of EIF3S3 on growth of NIH 3T3 murine fibroblasts as well as breast (SK-Br-3 and ZR-75-1) and prostate (PC-3 and LNCaP) cancer cell lines was examined by using transfection with inducible pTet-Off system and siRNAs.
