Pol II inhibition with α-amanitin (AMN) or flavopiridol for 30 min was sufficient to disrupt rRNA processing. IGS noncoding RNAs (ncRNAs) decreased in abundance following Pol I inhibition and increased with Pol II inhibition. Double inhibition decreased their abundance. Pol I transcribed sense intergenic ncRNAs (sincRNAs) and Pol II antisense intergenic ncRNAs (asincRNAs)."]]
