摘要:
Methods and compositions are provided for expression of mammalian genes in culture. An amplifiable gene is introduced by homologous recombination in juxtaposition to a target gene, the resulting combination of amplifiable gene and target gene transferred to a convenient host and the target gene amplified by means of the amplifiable gene. The resulting expression host may then be grown in culture with enhanced expression of the target gene.

The present invention provides anti-angiogenic compositions and methods, based on gene delivery vectors that include the coding sequence for an anti-angiogenic compound.
摘要:
The invention provides methods of treating neoplasia using combinations of target cell-specific replication competent adenoviral vectors and chemotherapy, radiation therapy or combinations thereof. The adenoviral vectors are target cell-specific for the particular type of neoplasia for which treatment is necessary and the combination with the chemotherapy and/or radiation leads to synergistic treatment over existing adenoviral therapy or traditional chemotherapy and radiation therapy.
摘要:
The present invention relates to methods and compositions for increasing the production of high titer stocks or recombinant AAV (rAAV) through regulation of expression of the AAV REP and CAP proteins. The methods and compositions of the invention are based on the observation that the low level expression of the AAV REP 78/68 protein increases the production of AAV viral capsid protein and efficiency of packaging resulting in production of higher titer recombinant viral stocks. The invention encompasses recombinant AAV vectors that direct the expression of AAV REP and CAP proteins and the use of such vectors for the production of novel stable cell lines capable of generating high titer rAAV vectors. The invention provides methods for regulating the expression of the AAV REP 78/68, REP 40/52 and CAP gene at the transcriptional and post-transcriptional level.
摘要:
Novel cationic polymers and cationic lipids, and methods of making and using the same, are provided. The cationic polymers and cationic lipids are useful for the delivery of nucleic acid polymers and oligomers to cells in vitro and in vivo.
摘要:
Lentiviral vectors modified at the 5' LTR or both the 5' and 3' LTR are useful in the production of recombinant lentivirus vectors (See the Figure). Such vectors can be produced in the absence of a functional tat gene. Multiple transformation of the host cell with the vector carrying the transgene enhances virus production. The vectors can contain inducible or conditional promoters.
