Neither the mechanism nor the biological significance for such over expression have been studied. We used microarrays to analyze changes in A549 lung cancer cell line in which ALDH activity was reduced using lentiviral mediated expression of siRNA against both isozymes (Lenti 1+3) Keywords: Gene Profiling after ALDH Knock Down2008/10/29GSE8045GSM198611GSM198610GSM198609GSM198608GSM198607GSM198606GSM198605GSM198604GSM198603GSM198613GSM198602GSM1986125708045Homo sapiens
