In this study, we first indicate that the role of EGCG in APP and ADAM10 regulation is mediated by HuR, result in tumour cells apoptosis via HuR‐Erk1/2‐APP/ADAM10 pathway, adding a new dimension to EGCG‐mediated regulation of APP and ADAM10 in cancer cell apoptosis. This evidence concerns the gene ELAVL1 and cancer.
