Galban et al reported that HuR‐regulated TP53 mRNA expression in renal carcinoma cells 45; Wang et al showed HuR‐regulated p21 expression via CDKN1A mRNA stabilization in colorectal carcinoma cells 46; and Pang et al implied that HuR regulated the expression of p16 via binding to mRNA in HeLa cells.47 This evidence concerns the gene CDKN1A and renal carcinoma.
