A tropism modified cancer terminator virus (Ad.5/3-CTV; Ad.5/3-CTV-M7) has been found to have infectivity that is Coxsackie Adenoviral Receptor (CAR) independent. The Ad.5/3-CTV (Ad.5/3-CTV-M7) may be used alone or in combination with other therapeutic agents such as agents that augment reactive oxygen (ROS) production, HDAC inhibitors, MCL-1 inhibitors and Bcl-2 inhibitors to treat a variety of cancers particularly including malignant glioma (GBM), renal cancer, prostate cancer, and colorectal cancer.

Provided are chimeric oncolytic adenoviruses simultaneously expressing IL-12, IFN-?, and CCL5, and an application thereof in tumor treatment. A capsid protein hexon of the oncolytic adenovirus is formed from chimerizing hexon sequences of the two serotype viruses Ad5 and Ad48, and a fiber protein is formed from chimerizing fiber sequences of the two serotype viruses Ad5 and Ad11. The chimeric oncolytic adenovirus can activate intrinsic anti-cancer activity of a variety of viral structural proteins, the ability to infect tumor cells is increased while also ensuring that the virus itself avoids interception from pre-existing neutralizing antibodies and adhesion and uptake of hepatocytes, and an effect of killing cancer cells is enhanced.

The present disclosure provides an oncolytic virus comprising a nucleic acid(s) encoding a granulocyte-macrophage colony-stimulating factor (GM-CSF) and a soluble form of the TGF-B receptor-II (sTGF-BRII). The present disclosure also provides compositions comprising the oncolytic virus and treatment methods using the oncolytic virus. The treatment methods include local and/or systemic administration of the oncolytic virus for treating cancers, such as solid tumors.

The present invention relates to at least one agent capable of increasing the level of one or more miRNA in a cell or cells of a subject, said miRNA comprising the sequence UUCCCUU, for use in the treatment and/or prevention of a retinal dystrophy, in particular characterized by photoreceptor degeneration, relative pharmaceutical compositions, nucleic acids, vectors and host cells.

The invention relates to an oncolytic adenovirus for the treatment of cancer, containing a human DNA sequence isolating a promoter conferring selective expression on an adenoviral gene. Said adenovirus can also contain a sequence that optimizes the protein translation of an adenoviral gene regulated by a promoter conferring tumor selectivity. The invention is suitable for use in the treatment of cancer.

Provided are an LncRNA and oncolytic adenovirus, and application thereof. The oncolytic adenovirus is used as a carrier to express the LncRNA, so as to express the LncRNA in a cancer cell; competitively binding a target gene of OncomiRs, and consuming the OncomiRs, thus protecting a cancer suppressor gene from interference and suppression of the OncomiRs, and achieving target intervention therapy of the cancer cell.

The invention relates to an adenovirus comprising a nucleic acid sequence encoding a Helicobacter pylori neutrophil-activating protein (NAP) and/or a nucleic acid sequence encoding an immunologically equivalent fragment of NAP and a nucleic acid sequence encoding an immunomodulator capable of inducing an immune response in a subject. The adenovirus has enhanced clinical effects in terms of delaying tumor growth and prolonging survival.

The present invention is related to the use of a virus, preferably an adenovirus, for the manufacture of a medicament, whereby the virus is replication deficient in cells which do not have YB-1 in the nucleus, and the virus codes for an oncogene or oncogene product, in particular an oncogene protein, which transactivates at least one viral gene, preferably an adenoviral gene, whereby the gene is selected from the group comprising E1B55kDa, E4orf6, E4orf3 and E3ADP.

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.

The present disclosure relates to a replication deficient oncolytic viral vector or replication capable group B oncolytic adenovirus selected from the group consisting of Ad11 and enadenotucirev, wherein the virus encodes an antibody or a binding fragment thereof for expression on the surface of a cancer cell, wherein said antibody or binding fragment is specific to a CD3 protein of a T-cell receptor complex (TCR), wherein the virus does not encode a B7 protein or an active fragment thereof, pharmaceutical compositions comprising the same, and use of any one of the same in treatment, particularly in the treatment of cancer.
