PTPN13 and hepatocellular carcinoma: The results of cell counting kit 8 (CCK-8), EdU, colony formation, and transwell assays showed that upregulated PTPN13 expression significantly suppressed the proliferation, migration, and invasion of PLC/PRF/5 and HCC-LM3 cells, while downregulated PTPN13 expression had the opposite effects on Huh7 and SMMC-7721 cells (Fig. 4B–E and Fig. S6B–F).
