Genome-wide view of the impact of Spt5-Pol II inhibitors (SPIs) on mRNA levels [RNA-Seq 24h]

We identified the first Spt5-Pol II inhibitors (SPIs). SPIs faithfully reproduced Spt5 knockdown effects on proximal-promoter-pausing, NF-?B activation and the expanded-repeat huntingtin gene in neuronal cells. We determined the global effect of short and long-term SPI-21 treatment by RNA-seq and compared the affected genes between the two treatments. The results revealed that temporary and constitutive Spt5-regulated genes can be distinguished by SPIs. Overall design: HeLa cells were treated for 24 hours with either DMSO or SPI-21 (50µM). Then total RNA was extracted and subjected to RNA-seq.
