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.

Synthetic adenoviruses with liver detargeting mutations and expressing an adenovirus type 34 (Ad34) fiber protein, or a chimeric fiber protein with an Ad34 knob domain, are described. The synthetic adenoviruses traffic to sites of tumors. Use of the synthetic adenoviruses for delivering diagnostic or therapeutic transgenes to tumors are also described.

Synthetic adenoviruses with tropism to bone tissue are described. The synthetic adenoviruses include an adenovirus type 11 (Ad11) fiber protein or a chimeric adenovirus fiber protein having an Ad11 knob domain. The synthetic adenoviruses can also include a transgene, such as a reporter gene or a transgene encoding a factor that promotes bone regeneration or repair. Use of the synthetic adenoviruses to target bone tissue and/or to promote bone repair or regeneration is also described.

A modified adenovirus capable of overcoming the problem of low level of coxsackie-adenovirus receptor (CAR) expression on tumor cells and methods of using such adenovirus are provided. The fiber protein of the adenovirus is modified by insertion or replacement so as to target the adenovirus to tumor cells, and the replication of the modified adenovirus is limited to tumor cells due to specific promoter control or mutations in E1a or E1b genes.

An adenovirus vector comprising: a pulmonary targeting coding sequence, CRISPR components such as a Cas9 coding sequence, and a guideRNA coding sequence which can be used for gene therapy. The adenovirus can be a gorilla adenovirus, and can include a pulmonary cell targeting sequence such as an MBP targeting ligand coding sequence. The adenovirus can be targeted to pulmonary epithelium with a vascular specific promoter and integrin targeting peptides incorporated into a viral knob. The adenovirus can be used to introduce serum proteins via the pulmonary epithelium. Hemophilia can be treated by adenoviral introduction of factor VIII or factor IX.

The invention concerns a modified low seroprevalence adenovirus: a pharmaceutical composition comprising same; and a method of treating cancer using same.

A delivery system that includes a recombinantly synthesized protein polymer with protease cleavage sites such as matrix metalloproteinase responsive sequences engineered within the protein polymer. The system may be used to treat cancer, wounds, or pathological conditions in other tissues that express excess protease relative to healthy tissue.

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.

Disclosed herein are methods and compositions for inactivating CCR-5 genes, using zinc finger nucleases (ZFNs) comprising a zinc finger protein and a cleavage domain or cleavage half-domain. Polynucleotides encoding ZFNs, vectors comprising polynucleotides encoding ZFNs, such as adenovirus (Ad) vectors, and cells comprising polynucleotides encoding ZFNs and/or cells comprising ZFNs are also provided.

The present invention relates to an anti-tumor adenovirus that can evade the in-vivo immune system. The adenovirus having high ability to kill tumor of the present invention, by comprising a nucleic acid encoding a tumor albumin-binding domain, has significantly increased effects of infecting and killing tumor cells, exhibits an increase in binding with albumin to thereby evade in-vivo immune responses, leading to an increase in plasma half-life, is specifically delivered to cancer cells to produce systemic therapeutic effects, and can be topically delivered and has excellent selectivity, resulting in a remarkable effect in anti-tumor efficacy and, therefore, the adenovirus can be advantageously used as an anticancer composition or anticancer adjuvant in various types of cancer.
