Methods: The recombinant plasmid pcDNA3.1(+)/LCRG1 was successfully constructed. The biological effects of LCRG1 on Hep-2 cell line were studied by cell transfection, cell growth observation colony formation analysis and tumorigenicity experiments. Results: The LCRG1 gene potently inhibited tumorgenesis in vitro and in vivo, as showed by dramatic growth arrest observed in cell growth analysis and suppression of anchorage-independent growth and tumorigenicity in nude mice. Conclusion: Our results suggested that LCRG1 may be a candidate of tumor suppressor gene.展开更多
