Analysis of relationships between expression of RIP 2 and invasion in colorectal cancer / 国际检验医学杂志

ABSTRACT

Objective To explore the expression of RIP2 in colorectal cancer(CRC)tissues,and the inva-sion and migration was observed after RIP2 was increased in CRC cell line.Methods 48 cases of CRC paraf-fin-embedded specimens and 56 cases of tumor-adjacent tissues were collected,and expressions of RIP2 was tested by immunohistochemistry(IHC).pEGFP-RIP2 plasmid and JetPRIME were employed to increase the RIP2 in SW480 cells,and variety of invasion and migration was tested in SW480 cells.Results It was showed that expressions of RIP2 was lower in CRC tumors than in tumor-adjacent tissues(P<0.05).After RIP2 in-creased,migration ability of SW480 cells weakened.Conclusion The expression of RIP2 was decreased in CRC tissues,and it was closely related to tumor cell's invasion and metastasis.
