细胞永生化使得培养细胞能够无限扩增。然而,细胞永生化的过程有时会改变原代细胞的原始性质。在这项研究中,我们进行了多聚腺苷酸尾RNA的表达谱从原代和永生化角膜上皮细胞表达猿猴病毒40大T抗原(SV 40)或突变型细胞周期蛋白依赖性激酶4(CDK 4),细胞周期蛋白D1,端粒逆转录酶(TERT)的组合。此外,我们研究了在有或无血清的培养基中培养的SV 40细胞的表达谱。完整表达模式的分析显示,无论血清的存在与否,SV 40永生化角膜上皮细胞显示出与野生型细胞不同的表达模式,而组合表达的角膜上皮细胞显示出与野生型细胞相对更接近的表达模式。描述报告数据的机器可访问元数据文件:10.6084/m9.figshare.14093807
Cellular immortalization enables indefinite expansion of cultured cells. However, the process of cell immortalization sometimes changes the original nature of primary cells. In this study, we performed expression profiling of poly A-tailed RNA from primary and immortalized corneal epithelial cells expressing Simian virus 40 large T antigen (SV40) or the combination of mutant cyclin-dependent kinase 4 (CDK4), cyclin D1, and telomere reverse transcriptase (TERT). Furthermore, we studied the expression profile of SV40 cells cultured in medium with or without serum. The profiling of whole expression pattern revealed that immortalized corneal epithelial cells with SV40 showed a distinct expression pattern from wild-type cells regardless of the presence or absence of serum, while corneal epithelial cells with combinatorial expression showed an expression pattern relatively closer to that of wild-type cells.
