METHODS: The shRNA specific to PTI-1 (PC-3) was synthesized and inserted into pEGFP/U6 by gene recombination technology to construct the expression vector, pEGFP/U6-mPs, which was then transfected into the cultured PC-3 cells.

• 方法:采用基因克隆技术,将合成的短发卡样特异性PTI1(PC3)RNA干扰寡核苷酸序列插入真核表达载体pEGFP/U6,构建PTI1(PC3)shRNA的真核表达载体,体外转染人前列腺癌PC3细胞,48h后观察细胞生物学变化;
