| 摘要 |
The present invention regards cancer-specific control sequences that direct expression of a polynucleotide encoding a therapeutic gene product for treatment of the cancer. Specifically, the invention encompasses breast cancer-, prostate cancer-, and pancreatic cancer-specific control sequences. Two breast cancer-specific sequences utilize specific regions of topoisomerase IIalpha and transferrin receptor promoters, particularly in combination with an enhancer. The prostate cancer-specific and pancreatic cancer-specific control sequences utilize composites of tissue-specific control sequences, a two-step transcription amplification sequence, and a post-transcriptional control sequence. In more particular embodiments, these polynucleotides are administered in combination with liposomes.
