  • Publication number: 20230070477
    Abstract: The present disclosure relates to methods and compounds for reprogramming metabolism in one specific retinal and neuronal cell type leading to improved cell and tissue survival and function. In particular, the present disclosure relates to increasing PGC1?/Pgc1? or NRF2/Nrf2 or inhibiting HIF/Hif or KEAP1/Keap1 to reprogram metabolism and survival of cells in a variety of neurodegenerative conditions, and specifically those which cause blindness.
    Type: Application
    Filed: February 8, 2021
    Publication date: March 9, 2023
    Inventors: Stephen H. Tsang, Xuan Cui, Nan-Kai Wang, Pei-Kang Liu

  • Publication number: 20210054372
    Abstract: The present disclosure provides for systems and methods to limit the duration of a gene editing machinery, such as an endonuclease system. A self-terminating mechanism may be introduced by placing one or more target sequences (targeted by the gene editing machinery) on a polynucleotide encoding at least one component of the gene editing machinery/system.
    Type: Application

    Inventors: Stephen H. Tsang, Wen-Hsuan Wu, Yi-Ting Tsai
  • Publication number: 20210017509
    Abstract: The present disclosure provides methods for treating autosomal dominant diseases in a subject. In some aspects, the methods involve the use of a gene editing enzyme with a pair of unique guide RNA sequences that targets both mutant and wildtype forms of autosomal dominant disease-related gene for destruction in cells, and then supplying the cells with wildtype autosomal dominant disease-related gene cDNA which is codon modified to evade recognition by the guide RNAs. These methods are broadly applicable to any autosomal dominant disease.
    Type: Application
    Filed: March 25, 2019
    Publication date: January 21, 2021
    Inventors: Wen-Hsuan Wu, Yi-Ting Tsai, Stephen H. Tsang
  • Publication number: 20200255859
    Abstract: The present application discloses cellular models for diseases of the eye. In addition, the present application discloses methods and compositions for treating or preventing diseases of the eye.
    Type: Application
    Filed: July 31, 2018
    Publication date: August 13, 2020
    Inventors: Richard R. Yang, Stephen H Tsang
  • Publication number: 20200172927
    Abstract: The present disclosure relates to methods and compounds for promoting anabolic pathways in neuronal cells leading to improved neuronal survival.
