A modified immune cell that has attenuated expression and/or activity of YTH N6-Methyladenosine RNA Binding Protein 2 (YTHDF2), and enhanced anti-tumor activity. A composition for stimulating T cell-mediated immune response to a cancer cell and/or a tumor antigen, including an agent capable of attenuating the expression and/or activity of YTHDF2, and a pharmaceutically acceptable excipient. A composition for treating cancer, comprising an agent capable of attenuating the expression and/or activity of YTHDF2. A method for activating an immune cell. A method for generating an immune cell. A method for treating a disease, disorder or condition associated with an expression of a tumor antigen in a subject in need thereof. A method for stimulating a T cell-mediated immune response to a cancer cell and/or a tumor antigen in a subject in need thereof.

Provided is an obsessive-compulsive disorder animal model and a production method thereof, in which a neuronal circuit connecting the basolateral amygdala (BLA) and the dorsomedial striatum (DMS) is activated. In the present disclosure, it was confirmed that the BLA and DMS are connected to each other, and that when the BLA-DMS neuronal circuit is activated, there is a large increase in checking, repeating, cleaning, and collecting, which are compulsive behaviors representative of obsessive-compulsive disorder, and a decrease in cognitive flexibility. Therefore, animals in which the BLA-DMS neuronal circuit is activated may be useful as animal models for studying obsessive-compulsive disorder. In particular, the obsessive-compulsive disorder animal model can reproduce all of the compulsive behaviors and thus may become the first animal model to provide an understanding of the interactions between anxiety behaviors and compulsive behaviors, which existing animal models have not been able to provide.

Provided herein are compositions, methods, and uses involving antibodies that immunospecifically bind glycosylated forms of MUC16, a tethered mucin protein. Also provided herein are uses and methods for managing, treating, or preventing disorders, such as cancer.

The present invention relates a vector system and a vector system for use in a method of treating a disease, each comprising a first vector and a second vector. The present invention further relates to the first vector, the second vector and a combination of the first vector and the second vector. In addition, the present invention relates to a pharmaceutical composition comprising the vector system of the invention or the combination of the invention.

In the present invention, it has been confirmed that, when an RNA interference-inducing nucleic acid including at least one 8-oxoguanine (o.sup.8G) in 1st to 9th nucleotides from the 5′-end of at least one single strand of a double strand of a nucleic acid, and a modified nucleic acid that specifically binds to microRNA and in which at least one guanine (G) from among the 1st to 9th nucleotides from the 5′-end are modified with 8-oxoguanine (o.sup.8G), are produced and administered to cells or mice, various pathophysiological phenomena are induced.

In addition, the positions where G>T modifications occur have been identified in cDNA produced through the reverse transcription of microRNA in which guanine (G) is oxidatively modified with 8-oxoguanine (o.sup.8G) by oxidative stress in a seed region of microRNA, to confirm the positions where oxidative modification to 8-oxoguanine has occurred.

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.

The present invention provides Factor IX fusion proteins with higher specific activity and a longer useful clotting function relative to wild type or non-modified Factor IX protein.

The present invention provides a kidney production method including a step of tissue-specifically removing a metanephric mesenchyme of a metanephros of a non-human animal; a step of transplanting, into the metanephros, a kidney precursor cell derived from a non-human animal which is allogeneic or xenogeneic to the non-human animal; and a step of advancing development of the metanephros, which is a step in which the transplanted kidney precursor cell is differentiated and matured to form a part of the kidney.

A transgenic non-human animal is provided. In certain embodiments, the animal comprises a genome comprising an immunoglobulin heavy chain locus comprising: a) a transcribed gene encoding a fusion protein comprising, from N-terminus to C-terminus: i. a scaffold comprising a first binding domain; and ii. a heavy chain constant region operably linked to the scaffold; wherein the scaffold is capable of specifically binding to a target in the absence of additional polypeptides; and b) a plurality of pseudogenes that are operably linked to the transcribed gene and that donate, by gene conversion, nucleotide sequence to the part of the transcribed gene that encodes the binding domain.

Compositions and methods are provided for creating and promoting biallelic targeted modifications to genomes within cells and for producing non-human animals comprising the modified genomes. Also provided are compositions and methods for modifying a genome within a cell that is heterozygous for an allele to become homozygous for that allele. The methods make use of Cas proteins and two or more guide RNAs that target different locations within the same genomic target locus. Also provided are methods of identifying cells with modified genomes.
