  • Publication number: 20250066814
    Abstract: A baculovirus vector and a use thereof in the preparation of a recombinant adeno-associated virus (rAAV) in an insect cell are provided. The baculovirus vector includes an exogenous gene expression cassette and a stable sequence. The stable sequence is located at a site 5 kb or less from the exogenous gene expression cassette, and the stable sequence is a conserved noncoding element (CNE) sequence or a nucleocapsid assembly-essential element (NAE) sequence. When an insect cell is infected with a recombinant baculovirus (rBV) constructed in this way, after multiple continuous passages, production levels of the rBV and the rAAV still remain relatively stable.

    Abstract: An expression cassette containing overlapping open reading frames and an application thereof are provided. The overlapping open reading frames are overlapping open reading frames of a first ORF and a second ORF and include in sequence from a 5? end to a 3? end: a first promoter at least used to drive gene transcription of the first ORF; a 5? part of a gene of the first ORF; an intron; and a 3? part of a gene of the second ORF, the intron including a second promoter used only to drive gene transcription of the second ORF. By arranging two promoters in a single expression cassette in the disclosure, the two promoters are used to drive the expression of proteins of the overlapping reading frames and regulate the relative expression time and expression intensity of different proteins.
