ABSTRACT
Cisplatin is the most common chemotherapeutic agent used in esophageal cancer. However, sensitivity to cisplatin varies greatly between patients. It is important to identify the gene(s) that are related to the sensitivity to cisplatin in esophageal cancer patients. The IC50 for cisplatin was measured for 15 esophageal cancer cell lines (TE1-5, TE8-15, KYSE140, and KYSE150). RNA was extracted from each of these cell lines and a normal esophageal epithelial cell line, namely, Het1A, and gene expression profiles were analyzed using an oligonucleotide microarray consisting of 34 594 genes. TE4 was highly resistant and TE12, 14, and 15 were sensitive to cisplatin. Thirty-seven genes were differentially expressed in the cisplatin-resistant esophageal cancer cell line. Our investigation provides a list of candidate genes that may be associated with resistance to cisplatin in esophageal cancer cells, which may serve as a basis for additional functional studies.
