ABSTRACT
Objective To detect EIA factor expression in human rectal cancer and normal tissue and to determine whether it is correlated with invasion and metastasis of human rectal cancer. Methods Real- time RT-PCR was used to detect E1AF expression in matched rectal cancers and normal tissues from g6 in- patients.Results Among the 86 rectal cancer samples tested,55 cases E1AF mRNA overexpression was ob- served. The mRNA expression of E1AF in the sample group was remarkably different from that in the control group.In carcinomas,E1AF mRNA expression correlated significantly with histological type,depth of inva- sion,lymph node and distant metastasis and advanced Duke stage.Conclusion E1AF is correlated signifi- cantly with invasion and metastasis of human rectal cancer and may be an important factor in the invasion and metastasis.
