| Research Abstract |
This study aimed at integrated development of the genetic detection of peritoneal micrometastases and effective therapy based on biological characteristics of peritoneal micrometastases. Microarray analysis was performed for the cell lines with low CEA expression and new marker genes were identified. The predicting model for peritoneal metastasis was constructed. Both sensitive and resistant cell lines for paclitaxel were establishedandgene expression profiling was compared with parent cell line. The selected genes were validated by clinical samples andidentified as paclitaxel-resistance related genes.
