ABSTRACT
OBJECTIVE@#To explore the differentially expressed gene profile in cervical squamous cell carcinoma tissues with and without pelvic lymph node metastasis by microarray technique and to screen tumor metastasis-related genes.@*METHODS@#Cancer tissue samples were collected from 4 cervical squamous cell carcinoma patients with pelvic lymph metastasis and 6 patients without metastasis before the treatment. Differentially expressed gene profile was identified between cervical squamous cell carcinoma tissues with and without pelvic lymph node metastasis by NimbleGen microarray. Fluorescent real-time quantitative PCR was employed to validate the accuracy of the microarray by detecting the expression of genes picked from the differentially expressed gene profile. We screened tumor metastasis-related genes through the gene bank, PUBMED and gene ontology analysis.@*RESULTS@#With the application of microarray, 329 genes were identified as markedly differentially expressed genes between cervical squamous cell carcinoma tissues with and without pelvic lymph node metastasis. Real-time PCR was in accordance with microarray. Forty-four genes associated with tumor metastasis were identified from the differentially expressed gene profile.@*CONCLUSION@#Gene profile in cervical squamous cell carcinoma tissues associated with pelvic lymph node metastasis is preliminarily identified, indicating that lymph node metastasis of cervical squamous cell carcinoma is a process involving numerous genes.
