| Outline of Final Research Achievements |
Transposon is a base sequence which transports to other location in the genome at random. Transposon is activated by transposase which is enzyme in transposon its self. Activatted transposon transports to other location in the genome (cut and paste). Inserting CMV promoter to transposon as a transcriptional activator, varioius cells which have vaious overexpressed genes or knocked down genes are obtained. Using this system into esophageal squamous cell cancer (ESCC), drug or radiation was added into these cells, and the resistant colonies were harvested to detect resistant gene. This new gene screening technique was useful for detecting candidate of drug-resistant genes and radio-resistant genes in esophageal squamous cell carcinoma. We identified 37 candidate genes responsible for CDDP resistance in the two cell lines derived from ESCC cells. Eleven genes were detected as candidate radioresistant genes in the two cell lines derived from ESCC cells.
