Some researchers have performed transcriptome sequencing on the longissimus dorsi muscles of different breeds and identified the differentially expressed circRNA host gene PPP2R3A (21), and Chen et al. found that knocking out PPP2R3A could significantly inhibit the proliferation of liver cancer cells, while the overexpression of PPP2R3A promoted the proliferation of two liver cancer cell lines (59). Here, PPP2R3A is linked to liver cancer.
