Abstract
目的 研究CyclinD1 mRNA反义寡脱氧核苷酸导入对颊癌细胞株BcaCD885生物学行为的影响,验证CyclinD1在口腔黏膜癌变中的作用.方法 采用差示PCR技术检测颊癌细胞株BcaCD885中CyclinD1 编码基因的扩增,并以脂质体为载体,将CyclinD1 mRNA的反义寡核苷酸序列转染肿瘤细胞,观察转染前后细胞增殖速度、体外集落形成能力的变化.结果 BcaCD885细胞株中出现CCND1基因扩增,扩增倍率6.9;转染CyclinD1mRNA的反义寡脱氧核苷酸后,细胞增殖速度减慢,体外集落形成能力下降.结论 转染CyclinD1 mRNA反义寡脱氧核苷酸,能部分抑制体外培养肿瘤细胞的增殖活性和恶性表型.
