Methods and compositions for in vivo gene editing based cell-type-specific cellular engineering
Disclosed herein include methods and compositions for incorporating an effector gene into the genome of a cell. The method can comprise introducing into a cell a donor nucleic acid comprising a recognition site, a splice acceptor site, a self-cleaving peptide sequence, an effector gene, and an optional transcript stabilization element. The donor nucleic acid can be incorporated into the intron of a target gene differentially expressed in a unique cell type and/or in a cell during a unique cell state via non-homologous end joining (NHEJ)-dependent DNA repair. There are also provided, in some embodiments, methods and compositions for treating a disease or disorder in a subject.
COMPOSITIONS AND METHODS FOR NON-TOXIC CONDITIONING
The invention features compositions and methods for conditioning a patient (e.g., to facilitate transplantation and/or engraftment). The invention provides a base editing strategy targeting cell surface proteins that is useful for conditioning. In one aspect, the invention provides methods of producing a hematopoietic stem cell or progenitor thereof for the treatment of a hemoglobinopathy, hematologic cancer, or myeloproliferative disease.
PRECISE INTRODUCTION OF DNA OR MUTATIONS INTO THE GENOME OF WHEAT
The present invention is in the field of genome editing and is directed to a method for the seam-less introduction of targeted precise modifications in genomic DNA of wheat.
PAM-REDUCED AND PAM-ABOLISHED CAS DERIVATIVES COMPOSITIONS AND USES THEREOF IN GENETIC MODULATION
The invention provides highly effective and versatile CRISPR/Cas protein variants, compositions, methods and uses thereof in gene editing. More specifically, the invention relates to PAM-reduced or PAM-abolished Cas proteins and chimeras, complexes and conjugates thereof, genetic editing systems and to therapeutic and non-therapeutic methods and uses of the PAM-reduced or PAM-abolished Cas proteins.
RNA-directed DNA cleavage by the Cas9-crRNA complex
Isolation or in vitro assembly of the Cas9-crRNA complex of the Streptococcus thermophilus CRISPR3/Cas system and use for cleavage of DNA bearing a nucleotide sequence complementary to the crRNA and a proto-spacer adjacent motif. Methods for site-specific modification of a target DNA molecule in vitro or in vivo using an RNA-guided DNA endonuclease comprising RNA sequences and at least one of an RuvC active site motif and an HNH active site motif; for conversion of Cas9 polypeptide into a nickase cleaving one strand of double-stranded DNA by inactivating one of the active sites (RuvC or HNH) in the polypeptide by at least one point mutation; for assembly of active polypeptide-polyribonucleotides complex in vivo or in vitro; and for re-programming a Cas9-crRNA complex specificity in vitro and using a cassette containing a single repeat-spacer-repeat unit.
CRISPR/Cas9 complex for introducing a functional polypeptide into cells of blood cell lineage
Provided herein are CRIS-PR/Cas9 complexes and methods of using same.
GENE-REGULATING COMPOSITIONS AND METHODS FOR IMPROVED IMMUNOTHERAPY
The present disclosure provides methods and compositions related to the modification of immune effector cells to increase therapeutic efficacy. In some embodiments, immune effector cells modified to reduce expression of one or more endogenous target genes, or to reduce one or more functions of an endogenous protein to enhance effector functions of the immune cells are provided. In some embodiments, immune effector cells further modified by introduction of transgenes conferring antigen specificity, such as exogenous T cell receptors (TCRs) or chimeric antigen receptors (CARs) are provided. Methods of treating a cell proliferative disorder, such as a cancer, using the modified immune effector cells described herein are also provided.
Nucleic acid, chimeric antigen receptor expression plasmid, chimeric antigen receptor expressing cell, use thereof, and pharmaceutical composition for treating cancer
The present disclosure relates to a chimeric antigen receptor, a nucleic acid, a chimeric antigen receptor expression plasmid, a chimeric antigen receptor expressing cell, a pharmaceutical composition for treating cancer, and use of the chimeric antigen receptor expressing cell. The chimeric antigen receptor is specific to human leukocyte antigen G. The nucleic acid encodes the chimeric antigen receptor. The chimeric antigen receptor expression plasmid expresses the chimeric antigen receptor. The chimeric antigen receptor expressing cell is obtained by transducing the chimeric antigen receptor into an immune cell. The pharmaceutical composition for treating cancer includes the chimeric antigen receptor expressing cell and a pharmaceutically acceptable carrier.
ALTERATION OF SEED COMPOSITION IN PLANTS
Provided are compositions comprising polynucleotides encoding modified MFT polypeptides. Also provided are recombinant DNA constructs, plants, plant cells, seed, and grain comprising the polynucleotides. Additionally, methods using the polynucleotides in plants to increase seed oil and/or protein content are also provided herein.
