TP53INP1 and hepatocellular carcinoma: Exosomal miR-93 promoted the proliferation and invasion of hepatocellular carcinoma (HCC) by directly inhibiting TP53INP1 (tumor protein p53-inducible nuclear protein 1), TIMP2 (TIMP metallopeptidase inhibitor 2), and CDKN1A (cyclin-dependent kinase inhibitor 1A) [246].
