The presently disclosed subject matter relates to using a haploid inducing line (whether existing or created) and transforming the haploid line so that it encodes cellular machinery capable of editing genes. The transformed haploid inducing line is used as a parent in a cross between two plants. During pollination, the parental gametes fuse to form an embryo; and the gene editing machinery is also delivered to the embryo at this time. During embryonic development, one set of parental chromosomes are lost, and the gene editing machinery operates on the remaining set of chromosomes. Thus, at least one haploid progeny with edited genes is produced from the cross.

The present invention provides compositions and methods for down-modulating the expression and/or the immuno-suppressive activity of i) the FMRP protein, ii) an mRNA encoding the FMRP protein, and/or iii) the FMR1 gene for the treatment and/or prevention of primary cancer and/or cancer metastasis in a subject in need thereof.

The invention relates to the field of personalized medicine, and the ability to administer targeted therapies consequently to biomarkers functional identification. In particular, the invention relates to the field of clinical applicable methods for the characterization, and especially the functional evaluation, of genetic variants in a patient. In particular, the invention relates to the field of the characterization, and classification, of variants of uncertain significance (VUS) or other unreported variants in patients. The in vitro method presented here is effective for the characterization of the functional impact of genetic variants in a patient, in particular of VUS, such as BRCA1 and BRCA2 VUS. The inventors have shown that this experimental framework can be used to obtain the necessary biological evidence of VUS function required for the prescription of targeted treatment within three weeks, which is compatible with use in clinical application.

Provided herein are compositions and methods for altering sensitivity of target cells to killing by γδ T cells.

Described herein are methods, compositions, and systems derived from uncultivated microorganisms useful for gene editing.

The present disclosure relates to genetically modified non-human animals that express a fusion protein including B2M and FcRn, and methods of use thereof. In some embodiments, the animals can have a B-NDG background. In some embodiments, the endogenous B2M gene is knocked out in the animals.

Methods of increasing T cell effector function in a T cell population are provided that involve inhibiting one or more genetic subunits of the SAGA (Spt-Ada-Gcn5-acetyltransferase) gene regulation complex in the T cell population. Also provided are methods of using such T cell populations in the treatment of cancer patients.

Provided is a system for multiplexed genome editing or a two or three-way combinatorial CRISPR screening. Also provided is high-throughput screening of disease-alleviating genetic combinations to identify two-way and three-way synergistic drug combinations as potential treatment regimens. Also provided is a lentiviral three-way combinatorial guide RNA expression cassette and combinatorial guide RNA libraries.

Strategies, systems, compositions, and methods for efficient production of knock-in cellular clones without reporter genes. An essential gene is targeted using a knock-in cassette that comprises an exogenous coding sequence for a gene product of interest (or “cargo sequence”) in frame with and downstream (3′) of an exogenous coding sequence or partial coding sequence of the essential gene. Undesired targeting events create a non-functional version of the essential gene, in essence a knock-out, which is “rescued” by correct integration of the knock-in cassette, which restores the essential gene coding region so that a functional gene product is produced and positions the cargo sequence in frame with and downstream of the essential gene coding sequence.

Compositions and methods are provided for introducing transgenic target sites for Site Specific Integration (SSI) and/or polynucleotides of interest into at least one double-strand break target site of a double-strand-break inducing agent in a genomic window of a plant genome. Also provided are methods and compositions for producing a complex trait locus in a genomic window of a plant comprising at least one transgenic target site for site specific integration integrated in at least double-strand-break target site. The double-strand-break target site can be, but is not limited to, a target site for a zinc finger endonuclease, an engineered endonuclease, a meganuclease, a TALENs and/or a Cas endonuclease. The genomic window of said plant can comprise at least one genomic locus of interest such as a trait cassette, a transgene, a mutated gene, a native gene, an edited gene or a site-specific integration (SSI) target site.
