  • Patent number: 11578321
    Abstract: The present invention discloses a method for assessing the capacity of a substance to treat or prevent hepadnavirus infection. A reporter virus carrying genetic information for a first fragment of a recombinase and a reporter cell expressing a second fragment of the recombinase are used. When the reporter virus infects the reporter cell, the two fragments of the recombinase associate and excise a stop cassette that is flanked by two recombination sites and blocks the expression of a reporter gene. Accordingly, the present invention relates to a method of assessing the capacity of a substance to treat or prevent hepadnavirus infection, a hepadnavirus comprising a nucleic acid encoding a first fragment of a recombinase and a mammalian hepatocyte or hepatoma cell comprising a nucleic acid encoding a second fragment of a recombinase and a nucleic acid comprising a stop cassette flanked by two recombination sites fused to a reporter gene.

  • Patent number: 11447768
    Abstract: The subject invention pertains to a Molecular Cell Diary System (MCDS), which allows identification of the history of somatic alterations in the cell. MCDS comprises one or more combinations of a DNA cutter and a DNA writer expressed under the control of a promoter controlled a cellular event of interest. The DNA cutter and the DNA writer are in a combination are co-expressed when an even of interest occurs. The DNA cutter creates double strand breaks (DSB) in a target DNA in a sequence specific manner and the DNA writer incorporates DNA sequences in the DSB. The endogenous DNA repair machinery synthesizes repairs the DSB. As such, the combination of the DNA cutter and the DNA writer modifies the target DNA and leaves “marks” of the occurrence of the cellular event of interest. These marks are sequenced and the cellular event history of the cell is deciphered.
