APP and liver cancer: Some studies reported that HuR correlated with patient outcome in liver cancer and interacted with lncRNA‐AK058003 to regulate proliferation and metastasis of hepatocellular carcinoma.7 Furthermore, in neurons, studies showed that HuD interacted with the 3’ UTRs of APP mRNA (encoding amyloid precursor protein) and BACE1 mRNA (encoding β‐site APP‐cleaving enzyme 1) and increased the half‐lives of these mRNAs.8 However, the role of HuR in APP expression and EGCG‐regulated APP expression in tumour is not clear.
