There are several reports about the relationship between HuR and ARE-mRNA (Brennan and Steitz, 2001) or the correlation between cytoplasmic HuR expression and malignancy in tumour cells (Lopez de Silanes et al, 2003, 2005; Denkert et al, 2004; Erkinheimo et al, 2005; Heinonen et al, 2005; Cho et al, 2007a, 2007b; Niesporek et al, 2008; Hasegawa et al, 2009). This evidence concerns the gene ELAVL1 and neoplasm.
