    • The invention belongs to the field of genetic engineering and biotechnology, and specifically discloses a design, preparation and pharmic application of a tumor-targeted TNF-related apoptosis-inducing ligand's variant. The tumor-targeted TNF-related apoptosis-inducing ligand's variant is generated by a fused protein which is consisted of the ligand of CD13, the connecting peptide and TNF-related apoptosis-inducing ligand's variant, and which is by the construction of coding gene of the variant according to the technology of genetic engineering and clone, soluble recombinant expression and ordinary separation and purification. The variant, produced by the method of preparation of the tumor-targeted TNF-related apoptosis-inducing ligand's variant, has favorable tumor-targeting characteristics and the significant enhancement of the anti-tumor effect. It is possible to reducing the required dosage of protein to the treatment effect, increasing the bioavailability, reducing the cost of treatment and overcome the potential toxic effects of the TNF-realated apoptosis-inducing ligand. Moreover, the preparation method of the tumor targeted TNF-related apoptosis-inducing ligand's variant of the present invention provides a method for producing the variant of soluble expression and high concern of polymer forms and a process of separation and purification thereof.
    • 本发明属于遗传工程和生物技术领域,具体公开了肿瘤靶向TNF相关凋亡诱导配体变体的设计,制备和药物应用。 肿瘤靶向的TNF相关凋亡诱导配体的变体由融合蛋白产生,其由CD13的配体,连接肽和TNF相关的细胞凋亡诱导配体的变体组成,并且通过构建编码基因的编码基因 该变体根据遗传工程技术和克隆,可溶性重组表达和普通分离纯化。 通过制备肿瘤靶向TNF相关凋亡诱导配体变体的方法产生的变体具有有利的肿瘤靶向特征和抗肿瘤效果的显着增强。 可以将所需的蛋白质用量减少到治疗效果,提高生物利用度,降低治疗成本,克服TNF-诱导的凋亡诱导配体的潜在毒性作用。 此外,本发明的肿瘤靶向的TNF相关凋亡诱导配体的变体的制备方法提供了生产可溶性表达变体和聚合物形式的高度关注的方法及其分离和纯化方法。
