As miRNAs are part of ribonucleoprotein complexes (RNPs), which additionally contain RNA-binding proteins like Argonaute 2 (AGO2) [26,27], we performed an AGO2-RNA immunoprecipitation (IP) using HepG2 and HuH7 liver cancer cells, which showed high LINC00152 expression levels (Figure 2A). This evidence concerns the gene AGO2 and liver cancer.
