The plasmid expression vector aiming directly at cerb-B1 gene might suppress cerb-B1 gene and EGFR expression in human colon cancer LoVo cells. The new therapeutic modalities could be used in the treatment for human colon cancer.

• 说明本研究构建的针对cerb-B1基因的质粒表达载体可以显著抑制cerb-B1基因和EGFR蛋白在人结肠癌LoVo细胞的表达,为结肠癌的基因治疗提供了新的思路。
