TRAF2 and breast cancer: In addition, several studies have reported that other TRAF proteins, such as TRAF2, can be regulated by certain miRNA molecules such as miR-502-5p (57), miR-514a-3p (58), and miR-892b (59) in breast cancer, suggesting that these miRNAs that regulate TRAF2 can serve as potential disquisitive objects in the study of HCC development and progression.
