摘要
目的:应用基因芯片检测盆腔淋巴结转移组和无转移组宫颈鳞癌组织中差异表达基因,从中筛选肿瘤转移相关基因。方法:利用基因芯片技术对4例盆腔淋巴结转移组和6例无转移组宫颈鳞癌组织标本进行差异表达基因检测,并用Real-time PCR对部分差异表达基因进行验证。通过基因库检索、PUBMED文献检索和基因本体分析从差异表达基因中筛选肿瘤转移相关基因。结果:从盆腔淋巴结转移组及无转移组宫颈鳞癌组织中筛选出表达差异明显的基因329个,通过Real-timePCR验证,基因芯片结果可靠。从差异表达基因中筛选出与肿瘤转移相关基因44个。结论:通过基因芯片筛查,初步建立了宫颈鳞癌转移相关差异基因表达谱,说明宫颈鳞癌的转移过程受多基因调控。
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 microarra）n 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.
