TITLE: VECTORS HARBORING TOXIC GENES, METHODS AND USES THEREFOR

Summary: The present disclosure describes nucleic acids, and viruses comprising such nucleic acids, for growing a toxic gene in an insect cell. These nucleic acids comprise a sequence encoding a toxic polypeptide, and an intron that interrupts the sequence, whereby the intron is spliced in mammalian cells but not in insect cells. Infection of mammalian cells but not insect cells with the nucleic acids or viruses can lead to expression of toxic levels of the toxic polypeptide in mammalian cells but not in insect cells. Viruses, such as an AAV or a baculovirus comprising a nucleic acid can be grown in insect cell lines in vitro and can be administered to a subject in need of therapy, such as a subject in need of cancer therapy.

I think it might infringe many other patents. My concern is about using some of the information from these patent in other diseases. Also what does here the toxic gene mean?

Note: It is my first post here, I might be confused but I followed this guide and it might be not really what I should do. If I can improve my question, please let me know.
