染色体比较基因组杂交(CGH)已被应用于宫颈癌进展的所有阶段,定义了这种肿瘤中染色体不平衡的特定模式。然而,由于其有限的空间分辨率,染色体CGH仅提供了关于DNA拷贝数变化的可能遗传靶点的一般信息。为了进一步定义宫颈癌中特定的DNA拷贝数变化,我们分析了20个宫颈样本(3个癌前病变、10个侵袭性肿瘤和7个细胞系),使用GenoSensor微阵列CGH系统来定义遭受拷贝数变化的特定遗传靶点。在侵袭性组织中,阵列CGH检测到的最常见的DNA增益位于RBP 1-RBP 2(3q 21-q22)基因、亚端粒克隆C84 C11/T3(5 ptel)、D5 S23(5p15.2)和DAB 2基因(5 p13),占58.8%。最常见的缺失发生在FHIT基因在47%的样本中,3p14.2缺失,其次是D8 S504缺失(8p23.3),CTDP 1-SHGC- 145820(18 qtel),套件(4q11-q12),D1 S427-FAF 1(1p32.3)、D9 S325(9 qtel)、EIF 4 E(真核翻译起始因子4 E,4 q24)、RB 1(13 q14)和DXS 7132(Xq 12)存在于5/17(29.4%)的样品中。我们的研究结果证实了宫颈癌中存在特定的染色体不平衡模式,并确定了这种肿瘤中遭受DNA拷贝数变化的特定靶点。
Chromosomal Comparative Genomic Hybridization (CGH) has been applied to all stages of cervical carcinoma progression, defining a specific pattern of chromosomal imbalances in this tumor. However, given its limited spatial resolution, chromosomal CGH has offered only general information regarding the possible genetic targets of DNA copy number changes. In order to further define specific DNA copy number changes in cervical cancer, we analyzed 20 cervical samples (3 pre-malignant lesions, 10 invasive tumors, and 7 cell lines), using the GenoSensor microarray CGH system to define particular genetic targets that suffer copy number changes. The most common DNA gains detected by array CGH in the invasive samples were located at the RBP1-RBP2 (3q21-q22) genes, the sub-telomeric clone C84C11/T3 (5ptel), D5S23 (5p15.2) and the DAB2 gene (5p13) in 58.8% of the samples. The most common losses were found at the FHIT gene (3p14.2) in 47% of the samples, followed by deletions at D8S504 (8p23.3), CTDP1-SHGC- 145820 (18qtel), KIT (4q11-q12), D1S427-FAF1 (1p32.3), D9S325 (9qtel), EIF4E (eukaryotic translation initiation factor 4E, 4q24), RB1 (13q14), and DXS7132 (Xq12) present in 5/17 (29.4%) of the samples. Our results confirm the presence of a specific pattern of chromosomal imbalances in cervical carcinoma and define specific targets that are suffering DNA copy number changes in this neoplasm.
