摘要:
The present invention provides a DNA molecule comprising a radiation responsive enhancer-promoter operatively linked to an encoding region that encodes at least one polypeptide. An encoding region can comprise a single encoding sequence for a polypeptide or two or more encoding sequences encoding DNA binding, activation or repression domains of a transcription factor. Processes for regulating polypeptide expression and inhibiting tumor growth using such DNA molecules are also provided.
摘要:
The present invention relates to methods for treating and preventing cancer and for treating precancerous lesions by administering a therapeutically effective dose of a vaccine comprising fusion cells formed by fusion of antigen presenting cells and non-dendritic cells that contain genomic DNA or cDNA derived from a tumor cell or a pre-cancerous cell to a cancer patient or patient with a precancerous lesion. In certain embodiments, such vaccines are administered in combination with a cytokine or other molecule that stimulates a cytotoxic T cell (CTL) response and/or a humoral immune response. The present invention also relates to methods for treating and preventing an infectious disease by administering a therapeutically effective dose of a vaccine comprising fusion cells formed by fusion of antigen presenting cells and non-dendritic cells that contain genomic DNA or cDNA derived from the infectious agent that causes the infectious disease to be treated or prevented to a subject. The present invention also related to methods for producing the fusion cells to be used with the methods of the invention. The present invention also provides compositions comprising the fusion cells to be used with the methods of the invention.
摘要:
Isolated DNA encompassing the DF3 enhancer as well as a sequence encoding a heterologous polypeptide provides epithelial tissue-selective gene expression of the heterologous polypeptide, useful in methods of therapy.
摘要:
Methods and compositions for enhancing cancer cell death using therapeutically effective amounts of DNA damaging agent(s) that act in combination to enhance cancer cell death, e.g., nucleic acid precursors, and protein tyrosine kinase inhibitors, e.g., that inhibit EGFR activity. The agents and inhibitors are administered in an amount effective to kill cancer cells, that is, the combined effect is sufficient so that cancer cell death is enhanced. If not administered at the same time, the DNA damaging agent(s) and tyrosine kinase inhibitors are administered close enough in time so they are still able to enhance cancer cell death. The methods and compositions are useful to treat neoplastic disease, e.g., pancreatic cancer.
摘要:
The invention is concerned with fusions of dendritic cells and with tumor or cancer cells. Also provided are methods of making and using these cell fusions, including methods of adoptive immunotherapy as well as methods of stimulating anti-tumor immunity using fused cells and anti-CD3/CD28 antibodies.
摘要:
The invention is concerned with fusions of dendritic cells and antigen presenting cells. Also provided are methods of making and using these cell fusions, including methods of adoptive immunotherapy. The fusions according to the invention can also be used in methods for antigen discovery.

摘要:
The present invention is directed to novel methods of enhancing the effectiveness of DNA damaging agents by exposing cells to viruses prior to or during exposure to the damaging agent. In certain embodiments of the invention, the DNA damaging agent is ionizing radiation, the virus is an adenovirus, and the increase in cell killing is synergistic when compared to radiation alone.
摘要:
The present invention relates to the signalling pathways connecting DNA damage, such as that induced by ionizing radiation or alkylating agents, and phosphorylation by tyrosine kinases.
