PRC1 and cancer: As a ARE-mRNA that consists of UUAUUUAUU motif, PRC1 has been found over-represented in several cancers, including HCC (Wang et al., 2017; Zhan et al., 2017) and is negatively correlated with a low ZFP36 and human antigen R (HuR, also known as ELAVL1) ratio (Al-Souhibani et al., 2010; Hitti et al., 2016).
