The facilitating chromatin transcription (FACT) complex, a heterodimer of SSRP1 and Spt16, has been shown to regulate transcription elongation through a chromatin template in vitro and on specific genes in cells. However, its global role in transcription regulation in human cells remains largely elusive. We conducted spotted microarray analyses using arrays harboring 8308 human genes to assess the gene expression profile after knocking down SSRP1 or Spt16 levels in human non-small cell lung carcinoma (H1299) cells. Although the changes of these transcripts were surprisingly subtle, there were approximately 170 genes whose transcript levels were either reduced or induced >1.5-fold. Approximately 106 genes with >1.2-fold change at the level of transcripts were the common targets of both SSRP1 and Spt16 ( approximately 1.3%). A subset of genes was regulated by SSRP1 independent of Spt16. Further analyses of some of these genes not only verified this observation but also identified the serum-responsive gene, egr1, as a novel target for both SSRP1 and Spt16. We further showed that SSRP1 and Spt16 are important for the progression of elongation RNA pol II on the egr1 gene. These results suggest that SSRP1 has Spt16-dependent and -independent roles in regulating gene transcription in human cells.
