Among them, the Elav (Embryonic Lethal Abnormal Vision) (e.g., HuR) and tristetraprolin family members (e.g., Tristetraprolin (TTP)) represent the most studied AUBPs due to their ability to control the expressions of key transcripts involved in metabolic (e.g., FGF21 (Fibroblast growth factor 21), PTEN (Phosphatase and TENsin homolog), PPARγ (Peroxisome proliferator-activated receptor gamma)), inflammatory (e.g., TNFα, COX-2) and cancer-related processes (e.g., c-Myc, VEGFα (Vascular Endothelial Growth Factor α)) [23]. Here, FGF21 is linked to cancer.
