Instead, drug-induction suggested decrease for ITGB1/CD29c and ALDH1B1, while CD24, CD44, CD166, ALDH1A1 and Lgr5 were unchanged as detected by signals from microarrays with pooled tumor RNA from indomethacin-treated patients versus pooled tumor RNA from control patients. The gene discussed is ALDH1A1; the disease is neoplasm.
