摘要:
The p21 gene encodes a cyclin dependent kinase inhibitor which affects cell cycle progression, but the role of this gene product in altering tumor growth has not been established. The present inventors have now discovered that the growth of malignant cells in vivo is inhibited by expression of p21. Expression of p21 resulted in an accumulation of cells in G.sub.0 /G.sub.1, alteration in morphology, and cell differentiation.
摘要:
The present invention provides a combination including a double-balloon catheter and a nucleic acid encoding the cyclin dependent kinase inhibitor p21. The nucleic acid may also encode HLA-B7, an immunotherapeutic agent, a cytokine or a prodrug converting enzyme.

摘要:
A method for the direct in vivo transformation of cells in and surrounding a solid tumor is disclosed. This method is based on the site-specific delivery of proteins to solid tumors and to tissue surrounding the solid tumor by direct injection of a nucleic acid sequence. In particular, this method is directed to site-specific delivery of nucleic acids encoding major histocompatibility proteins, cytokines, and toxins to a solid tumor. This technique provides for the transfer of vectors and expression of recombinant genes in vivo and allows the introduction of proteins of therapeutic or diagnostic value for the treatment of disease.

摘要:
A method for inhibiting restenosis associated with mechanical injury of a blood vessel. An adenoviral vector encoding a suicide gene such as thymidine kinase is directly administered to the injured vessel followed by treatment with a nucleotide analog. The analog is phosphorylated and converted to a cytotoxin by the suicide gene product, resulting in destruction of the rapidly dividing neointimal cells.
