Novel hexon isolated from simian adenovirus serotype 19 encoded in the polynucleotide defined as SEQ ID NO: 3, hepervariable region thereof, chimeric adenovirus comprising the same, and therapeutic use thereof provides a solution to the problem of safety and effective systemic treatment for developing gene therapeutic agents using adenovirus.

Synthetic adenoviruses having chimeric fiber proteins and liver detargeting mutations are described. The synthetic adenovirus vectors are capable of specifically infecting cells at wound sites or in regions of damaged tissue. The synthetic adenovirus vectors also are capable of expressing transgenes, such as wound healing factors, at sites of wounded or damaged tissue. Accordingly, the described vectors can be used to detect wounded or damaged tissue, and/or to promote wound healing and regeneration of damaged tissue, such as by expression of heterologous wound healing or tissue regeneration factors.

Compositions and methods for retargeting adenovirus to a cell using chemical dimers are described. In particular, a recombinant adenovirus comprising a nucleic acid comprising a capsid-dimerizing agent binder conjugate and a ligand-dimerizing agent binder conjugate is provided.

The present disclosure describes the generation and the use of Ad variants (Ad) possessing any combination of mutations in genes that code for the hexon, penton, fiber, and non-structural proteins, where simultaneous modification of hexon and penton are made to avoid the trapping of Ad in the liver and to reduce toxicity after intravascular virus administration. Such liver de-targeted Ad can be useful tool for selective and specific gene delivery to extra-hepatic tissues and cells, including disseminated metastatic cancer cells.

The invention provides a replication-deficient serotype 28 adenoviral vector characterized by comprising a portion of a serotype 45 adenoviral hexon protein and/or a portion of a serotype 45 fiber protein in place of the endogenous serotype 28 hexon and/or fiber protein.

This invention relates to methods and materials for nucleic acid delivery, vaccination, and/or treating cancer. More specifically, methods and materials for nucleic acid delivery, vaccination, and/or treating cancer using one or more recombinant adenoviruses (Ads) as an oncolytic agent are provided.

Compositions and methods for retargeting adenovirus to a cell using chemical dimers are described. In particular, a recombinant adenovirus comprising a nucleic acid comprising a capsid-dimerizing agent binder conjugate and a ligand-dimerizing agent binder conjugate is provided.

A recombinant vector comprises simian adenovirus 43, 45, 46, 47, 48, 49 or 50 sequences and a heterologous gene under the control of regulatory sequences. A cell line which expresses simian adenovirus 43, 45, 46, 47, 48, 49 or 50 gene(s) is also disclosed. Methods of using the vectors and cell lines are provided.

Recombinant vectors in which expression of one or more elements (e.g. gene required for viral replication, detectable imaging agents, therapeutic agents, etc.) is driven by an mda-9/syntenin (mda-9) cancer selective promoter are provided, as are cells and transgenic animals that contain such vectors. The vectors are used in cancer therapy and/or diagnostics, especially to visualize (image) and treat metastasis (including in rapid in vitro assays), and the transgenic mice are used to monitor cancer progression and/or the efficacy of candidate therapeutic agents in screening assays.
