  • Publication number: 20220298514
    Abstract: The invention described herein provides methods and compositions for using recombinant AAV-based viral vectors to express any gene-of-interest (GOI), preferably from muscle and/or liver tissues, for secretion of the polypeptides encoded by the GOI into the bloodstream, thus serving as an alternative treatment regimen for diseases caused by or characterized by lack of functional GOI, or for disease caused by or characterized by a pathological antigen that can be neutralized by a neutralizing peptide encoded by the GOI, such as an immunoglobulin, antibody, or antigen-binding fragment thereof. The method/composition of the invention can be used as an alternative for enzyme replacement therapy (ERT), or for antibody-based therapy.

  • Publication number: 20220031865
    Abstract: The invention described herein provides gene therapy vectors, such as adeno-associated virus (AAV) vectors, that co-express a functional protein (such as a miniaturized human micro-dystrophin gene product) and one or more additional coding sequences for an RNAi sequence (siRNA, shRNA, miRNA), an antisense sequence, a guide sequence for a gene editing enzyme (such as an sgRNA for CRISPR/Cas9, or a crRNA for CRISPR/Casl2a), and/or a micro RNA, and methods of using the vectors to treat subjects suffering from a muscular dystrophy such as DMD/BMD.

  • Publication number: 20210009991
    Abstract: Methods and apparatus relate to reduction of sequence errors generated during synthesis of nucleic acids on a microarray chip. The error reduction can include synthesis of complementary stands (to template strands), using a short universal primer complementary to the template strands and polymerase. Heteroduplex can be formed be melting and re-annealing complementary stands and template strands. The heteroduplexes containing a mismatch can be recognized and cleaved by a mismatch endonuclease. The mismatch-containing cleaved heteroduplexes can be removed from the microarray chip using a global buffer exchange. The error free synthetic nucleic acids generated therefrom can be used for a variety of applications, including synthesis of biofuels and value-added pharmaceutical products.
