Methods Human pancreatic carcinoma cell lines SW1990, Capan-1 (Cap), AspC-1 (ASPC), P3, PANC-1 (Pan-1) and MIAPaCa-2 (MIA) were tested for MT level and radio-sensitivity using ELISA and clonogenic assay, respectively.

• 方法分别采用外源性锌离子及反义寡聚核酸(AS)转染P3、Pan-1、MIA、SW1990、Cap、ASPC等6株胰腺癌细胞,调节MT表达,随后应用ELISA及集落实验检测MT表达水平及放射敏感性指标存活分数(SF2)的变化。
