Lou et al. (2019) suggested that PTTG3P expression positively associated with PTTG1 expression and may function by sponging miR-129-5p, miR-383-5p, and miR-376c-3p. Recently, Zhou Q. et al. (2019) reported that downregulation of PTTG3P promoted apoptosis and decreased proliferation, invasion and migration of HCC cells via increasing the expression levels of miR-383 targets, PARP2 and CCND1. This evidence concerns the gene PTTG1 and hepatocellular carcinoma.
