Abstract

Lymphatic metastasis is a major mechanism of tumor metastasis. The present study aimed to investigate the association of CRKII, a member of the CRK family, with the in vitro malignant behaviors of a murine hepatocarcinoma Hca‑P cell line, with a lymph node metastatic rate of ~25%. Total mRNA was extracted from Hca‑P cells, and then the murine CRKII gene was amplified by polymerase chain reaction and cloned into the pEASY‑blunt cloning vector. Subsequently, the recombinant pcDNA3.1/V5‑HisB‑CRKII plasmid was constructed and transfected into Hca‑P cells. Western blotting indicated that the CRKII expression level in pcDNA3.1/V5‑HisB‑CRKII‑Hca‑P cells was increased by ~185%, compared with pcDNA3.1/V5‑HisB‑Hca‑P cells. The stable overexpression of CRKII enhanced the in vitro proliferation ability, as measured with a Cell Counting Kit‑8 assay, and the colony forming capacity was measured with a soft agar colony forming assay for Hca‑P cells. The in vitro migration and invasion capacities of Hca‑P cells were increased by ~179 and 156% in Hca‑P cells, respectively, following the stable upregulation of CRKII. Collectively, the recombinant pcDNA3.1/V5‑HisB‑CRKII‑Hca‑P plasmid was constructed successfully. Additionally, the CRKII expression level was positively associated with the in vitro proliferation, migration and invasion malignant properties of Hca‑P cells.
