Transcription profiling of mouse embryonic stem cells with a doxycycline-inducible Xist cDNA transgene introduced into chromosome 17

ABSTRACT: A doxycycline-inducible Xist cDNA transgene was introduced into mouse chromosome 17 at approximately 71.24Mb (NCBI Build m36). Insertion of the transgene was heterozygous, so only one copy of chromosome 17 carried the transgene, and the other chromosome 17 was wild-type. Upon doxycycline induction, the transgene is expressed, producing Xist transgene RNA which localises to autosomal material in cis, leading to silencing of genes adjacent to the transgene. Due to the heterozygous nature of transgene insertion and the cis nature of silencing, for any silenced gene, the maximum possible downregulation in expression levels was 50%.



To quantify the changes in the levels of gene expression in response to Xist transgene expression, total RNA was extracted from undifferentiated a
