    • The present invention relates to modified nucleic acid sequences coding for coagulation factors preferably coagulation factor VIII and their derivatives, recombinant expression vectors containing such nucleic acid sequences, host cells transformed with such recombinant expression vectors, recombinant polypeptides and derivatives coded for by said nucleic acid sequences which recombinant polypeptides and derivatives do have biological activities and prolonged in vivo half-life compared to the unmodified wild-type protein. The invention also relates to corresponding sequences that result in improved in vitro stability. The present invention further relates to processes for the manufacture of such recombinant proteins and their derivatives are covered. The invention also relates to a transfer vector for use in human gene therapy, which comprises such modified nucleic acid sequences.
    • 本发明涉及编码凝血因子,优选凝血因子VIII及其衍生物的修饰的核酸序列,含有此类核酸序列的重组表达载体,用此类重组表达载体转化的宿主细胞,重组多肽和由所述核酸序列编码的衍生物 与未修饰的野生型蛋白质相比,重组多肽和衍生物确实具有生物学活性和延长的体内半衰期。 本发明还涉及导致体外稳定性改善的相应序列。 本发明还涉及制备这种重组蛋白及其衍生物的方法。 本发明还涉及用于人基因治疗的转移载体,其包含这种修饰的核酸序列。
