Identification of human miR-34a-responsive transcripts

In order to examine the consequences of human miR-34a induction on the transcriptome, HCT116 cells (a colon cancer cell line) were infected with a retrovirus that produces miR-34a. Gene expression profiles were then monitored using Affymetrix microarrays. Affymetrix microarrays were used to examine the transcriptomes of HCT116 cells infected with an empty retroviral vector (pMSCV-PIG) or a retroviral vector that expresses human miR-34a. Keywords: comparison of cells with or without enforced miR-34a expression RNA from retrovirally-infected cells was isolated and hybridized to Affymetrix microarrays.
