摘要 利用基因工程技术,将天然IFN-γ分子的N端132个氨基酸与带有上皮生长因子(EGF)样多肽C端保守序列融合,构建了干扰素重组体IFN-γ132PGIX_(16).其中X_(16)由EGF样多肽C端16个氨基酸组成,PGI为连接肽序列。将此重组体基因插入表达载体pBV220P_RP_L串连启动子下游,转化大肠杆菌DH5α,在cIts857基因的调节下,通过升温诱导表达.表达产物与其母体天然IFN-γ相比,不仅保持了较高的抗病毒活性,抗病毒滴度达530MU/L菌液,而且明显地提高了抗肿瘤细胞增殖活性.在EGF存在的条件下,干扰素重组体的抗鼻咽癌细胞CNE-2增殖活性明显高于其母体分子(p<0.01).提示重组体分子IFN-γ132PGIX_(16)同时具有EGF受体干扰活性.
