Human antigen R (HuR) is one of the most extensively studied RBPs in tumors and can enhance the stability of mRNA or promote the translation of target mRNA, such as BCL2, silent information regulator sirtuin 1 (SIRT1), and X-linked inhibitor of apoptosis (XIAP), ultimately leading to the increased proliferation, survival, and invasion capabilities of tumor cells [59]. Here, XIAP is linked to neoplasm.
