This disclosure relates to targeted protease compositions and uses related thereto. In certain embodiments, the disclosure relates to nanoparticles wherein a targeting molecule is linked to the nanoparticle and wherein a catalytic domain of a protease is linked to the nanoparticle. In certain embodiments, the targeting molecule and the catalytic domain are within a single polypeptide sequence. In certain embodiments, the targeting molecule binds a molecule more highly expressed on cancer cells then non-cancerous cells, and the nanoparticles disclosed herein are used for the treatment of cancer by further attaching an anti-cancer agent to the nanoparticle or incorporating an anticancer agent within the nanoparticle.

Isolated or recombinant EphA5 or GRP78 targeting antibodies are provided. In some cases, antibodies of the embodiments can be used for the detection, diagnosis and/or therapeutic treatment of human diseases, such as cancer. A method of rapidly identifying antibodies or antibody fragments for the treatment of cancer using a combination of in vitro and in vivo methodologies is also provided.

The present invention concerns new nucleic acid molecules which may be used in many applications, and methods for making the same. These nucleic acid molecules are preferably DNA vectors, optionally DNA expression vectors. The nucleic acid molecules are able to target the vector to a specific cellular location, such as the nucleus, due to the presence of one or more particular binding motifs within the nucleic acid molecule itself. Thus, the nucleic acid molecules of the invention may also be described as targeted delivery vectors, notably self-targeted delivery vectors or smart delivery vectors.

Cancer eradicating engineered bacteriophage are described that can display a high copy number of a targeting polypeptide that can bind a surface antigen of a cancer cell. The bacteriophage can also display a high copy number of a cancer therapy, one or more of a drug, a toxin, an inhibitor, a radionuclide, etc. The targeting polypeptides and the cancer therapies can be directly or indirectly fused to coat proteins of the phage. The engineered phage can exhibit high avidity for cancer cells and can deliver a large dose of a cancer therapy per particle to the cell.

Compositions and methods are provided for modifying a genomic locus of interest in a eukaryotic cell, a mammalian cell, a human cell or a non-human mammalian cell using a large targeting vector (LTVEC) comprising various endogenous or exogenous nucleic acid sequences as described herein. Further methods combine the use of the LTVEC with a CRISPR/Cas system. Compositions and methods for generating a genetically modified non-human animal comprising one or more targeted genetic modifications in their germline are also provided.

Compositions and methods are provided for modifying a rat genomic locus of interest using a large targeting vector (LTVEC) comprising various endogenous or exogenous nucleic acid sequences as described herein. Compositions and methods for generating a genetically modified rat comprising one or more targeted genetic modifications in their germline are also provided. Compositions and methods are provided which comprise a genetically modified rat or rat cell comprising a targeted genetic modification in the rat interleukin-2 receptor gamma locus, the rat ApoE locus, the rat Rag2 locus, the rat Rag1 locus and/or the rat Rag2/Rag1 locus. The various methods and compositions provided herein allows for these modified loci to be transmitted through the germline.

Disclosed herein, in part, are methods for the expression and production of a trivalent, bispecific antibody using a recombinant nucleic acid comprising multiple, different expression cassettes in a specific and defined sequence, which are stably integrated into the genome of a mammalian cell.by targeted integration.
