    摘要: Complexes between internalizing factor-bonding factor conjugates and nucleic acid which can be taken up into higher eukaryotic cells by endocytosis containing, in non-covalently bound form, one or more substances having an affinity for nucleic acid, which are capable of increasing the efficiency of absorption of the complexes into the cells. The non-covalently bound substance having an affinity for nucleic acid may optionally be identical to the bonding factor, preferably a polycationic substance. The internalizing factor is preferably transferrin. Processes for preparing the complexes and processes for introducing nucleic acid into higher eukaryotic cells. Pharmaceutical preparations containing complexes with a therapeutically active nucleic acid.

    摘要: The invention relates to a system for transporting nucleic acids into the cell, which is effected by receptor-mediated endocytosis. Using a transferrin-polycation conjugate, a complex can be formed with the polyanionic nucleic acid. This complex is bound to the transfertin receptor, which is highly regulated in growing cells, and absorbed into the cell. Suitable nucleic acids include those which inhibit specific genes or the RNA function, such as antisense oligonucleotides or ribozymes or the genes coding for them. The invention further relates to a process for introducing nucleic acids into the cells, transferrin-polycation/nucleic acid complexes and pharmaceutical preparations containing them.

    摘要: The invention relates to a genetic unit, optionally present as a multiple-copy, for inhibiting RNA. The unit contains the transcription units necessary for transcription by polymerase III and a DNA coding for inhibiting RNA, which is arranged within the unit in such a way that the transcribed RNA is part of the polymerase III transcript. Using these units it is possible to achieve increased stability of the inhibiting RNA, which may occur in the form of ribozymes or antisense-RNAs, whilst maintaining an undiminished activity. The invention further relates to a process for introducing the genetic units into the cell, the use of these units and pharmaceutical preparations containing them.
