Abstract: Provided is an adeno-associated virus (AAV) complex for expression of an RUNX3 gene including an asymmetrically modified inverted terminal repeat (ITR). The AAV complex has asymmetric ITRs in which one of the two ITRs is modified, thereby increasing self-replication efficiency in host cells and increasing expression efficiency of a delivered gene, and therefore, compared to existing AAV complexes, the AAV complex has an advantage of improved productivity and gene expression efficiency.

Abstract: Described herein is a nucleic acid molecule including an asymmetrically modified inverted terminal repeat (ITR). An AAV vector including the nucleic acid molecule has advantages of increased productivity and expression efficiency of a transgene, and decreased genotoxicity, by having an asymmetric ITR in which any one of two ITRs is modified. Also, described herein is are compositions and vectors.

Abstract: In the present invention, it was confirmed that the modified protein in which the 356th serine of Runx3 is substituted with alanine has an increased activity of maintaining the complex with Brd2 by more than 10 times compared to the wild-type Runx3, and the apoptosis effect is improved in various cancer cell lines compared to the wild-type Runx3. Therefore, the modified protein in which the 356th serine of Runx3 is substituted with an amino acid that cannot be phosphorylated by a kinase of the present invention, the polynucleotide coding thereof, the vector carrying the polynucleotide, or the virus or cell transformed with the vector can be used as a therapeutic agent for various cancers.

Abstract: The invention relates to novel binding domain-immunoglobulin fusion proteins that feature a binding domain for a cognate structure such as an antigen, a counterreceptor or the like, a hinge region polypeptide having either zero or one cysteine residue, and immunoglobulin CH2 and CH3 domains, and that are capable of ADCC and/or CDC while occurring predominantly as monomeric polypeptides. The fusion proteins can be recombinantly produced at high expression levels. Also provided are related compositions and methods, including immunotherapeutic applications.

Abstract: The invention relates to novel binding domain-immunoglobulin fusion proteins that feature a binding domain for a cognate structure such as an antigen, a counterreceptor or the like, a wild-type IgG1, IGA or IgE hinge region polypeptide or a mutant IgG1 hinge region polypeptide having either zero, one or two cysteine residues, and immunoglobulin CH2 and CH3 domains, and that are capable of ADCC and/or CDC while occurring predominantly as polypeptides that are compromised in their ability to form disulfide-linked multimers. The fusion proteins can be recombinantly produced at high expression levels. Also provided are related compositions and methods, including cell surface forms of the fusion proteins and immunotherapeutic applications of the fusion proteins and of polynucleotides encoding such fusion proteins.
