| Research Abstract |
The possible antiproliferative potency of human recombinant interferon-β (hIFN-β ) towards ten human esophageal cancer cell lines was examined.
The cell growth of esophageal cancer cell lines was inhibited by hIFN-β in a dose- and time-dependent manner. When the esophageal cancer cells were treated with 5-fluorouracil (5-FU) in the presence of a low concentration of hIFN-β, the effectiveness of 5-FU was markedly enhanced.
When human esophageal cancer cells were transfected with hIFN-β gene entrapped in cationic multilamellar liposomes, the growth of all cancer cells tested was suppressed in a dose-dependent manner.
The effectiveness of 5-FU was also enhanced in the presence of a low concentration of liposome-entrapped gene.
The growth of the tumor of human esophageal cancer cells implanted to the nude mice was suppressed by hIFN-β gene entrapped in cationic multilamellar liposome.
The approach to the esophageal tumor is not so difficult by endoscopy. Gene therapy using hIFN-β gene entrapped in cationic multilamellar liposome is readily achievable and sure to be an effective tool for esophageal cancer.
