POLRMT is responsible for the production of cytoplasmic and nuclear form of mitochondrial RNA polymerase. The former (mtRNAP) participates in transcription of RNA in the mitochondria while the latter (spRNAP-IV) is responsible for some mRNA transcription in the nucleus. The nature and amount of genes transcribed by spRNAP-IV still remains unclear. Thus, we scanned for possible candidate genes by using Affymetrix. MCF-7 cell line was subjected to siRNA knockdown of either non-targeting, POLRMT, or PolII for 72 hoursE-GEOD-28503http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-28503/samples/
