Human Fibroblast cells immortalised cells: Control vs DNA damage

Transcriptional profiling of human fibroblast cells after DNA damage with Camptothecin or Etoposide or Neocarzinostatin Upon DNA damage, the DNA damage response (DDR) elicits a complex signaling cascade, which includes the induction of multiple non-coding RNA species. Recently long non-coding RNAs (lncRNAs) have been shown to contribute to DDR by regulating gene expression. However, very little is known about the role that lncRNAs play in regulating DNA Repair. Using a genome-wide microarray screen we identified a novel ubiquitously expressed lncRNA, DDSR1 (DNA damage-sensitive RNA 1), which is induced upon DNA damage by several DNA double-strand break (DSB) agents. Two-condition experiment, Control vs. DNA damage human fibroblast cells. No Replicates, DNA damage was induced with either Camptothecin or Etoposide or Neocarzinostatin, Total RNA or Nuclear RNA was profiled.
