The invention provides a Gene sequence which can encode and express adenovirus hexon protein in vitro, and is represented as SEQ ID NO: 3. Also invented a protein which was translated and expressed by the gene sequence according to the invention, and the invention also relates to the use of the protein as an antigen to immunize rabbits to obtain a polyclonal antibody. The antibody mentioned above can detect adenovirus with high sensitivity and specificity.

The present invention provides recombinant adenoviral compositions and methods for their use in treating disorders associated with epithelial tissues.

A method for treating a bone and soft tissue tumor, including administering a conditionally replicating adenovirus having a E1A gene under expression control of a Survivin promoter, to a subject in need thereof. A conditionally replicating adenovirus including a E1A gene under expression control of a Survivin promoter and the conditionally replicating adenovirus is not defective in a E3 region.

Recombinant vectors comprise simian adenovirus A1321 (SAdV-A1321), SAdV-A1325, SAdV-A1295, SAdV-A1309, SAdV-A1316, and/or SAdV-A1322 sequences and a heterologous gene under the control of regulatory sequences. A cell line which expresses simian adenovirus SAdV-A1321, SAdV-A1325, SAdV-A1295, SAdV-A1309, SAdV-A1316, and/or SAdV-A1322 gene(s) is also disclosed. Methods of using the vectors and cell lines are provided.

The present invention relates to a novel adenoviral vector not including a replication competent adenovirus. A recombinant E1/E3/E4-deleted adenoviral vector, of the present invention, in which an antigenic protein and an E4orf6 gene are inserted in an E1 gene-deleted region, has adenovirus productivity, degree of antigen expression, neutralizing antibody production amount, and T cell induction ability that are similar to those of a control group, and thus can be effectively used as a carrier for various vaccines for diseases or anti-cancer vaccines.

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.

The present invention describes generation and the use of adenovirus variants (Ad) possessing modified capsid penton base protein where mutations in the penton based RGD loop are made to avoid Ad binding to cellular 3-integrins. Specifically, the ablation of Ad penton base interaction with cellular 3-integrins results in reduced activation of inflammation after intravenous Ad administration. Further, the introduction into penton RGD loop of non-RGD containing peptides, which mediate virus entry into the cell via new cellular receptors, allows for the efficient Ad-mediated gene delivery into target cells in vivo after intravascular virus administration and triggers significantly reduced toxicity associated with Ad injection.

Provided herein are compositions and methods for the viral gene therapy (e.g., AAV-directed gene therapy) of cholesterol storage diseases or disorders, such as Niemann-Pick disease, Type C.

The present invention relates to a cancer initiating cell comprising an isolated coxsackievirus and adenovirus receptor positive mouse pulmonary stem/progenitor cell that overexpresses Oct-4.

Modified E1a regulatory sequences are provided, wherein at least one Pea3 binding site, or a functional portion thereof, is deleted. Also provided are modified E1a sequences that selectively express particular isoforms. Also provided is an E1b-19K clone insertion site. These modified sequences can be used individually, or in combination with one another, to provide tumor-selective expression of proteins.
