Sets linked with mitosis are negatively enriched. The best 5 ranked positively and negatively enriched gene sets are shown around the right. (C) GSEA plots for chosen hallmark gene sets, with black bars indicating gene sets represented amongst all genes ranked by log2-fold adjust (shCDK19 versus shCTRL). (D) Heat maps displaying average expression, calculated in the reads per kilobase per million (RPKM), in the p53 pathway and cholesterol homeostasis genes; only genes meeting an FDR q 0.1 threshold are shown. (E) Heat map of Metascape-enriched clusters. Each and every cluster includes many gene sets to do away with redundancy. Analysis utilized genes meeting an FDR q 0.1 threshold.5-FU treatment, 824 genes have been upregulated, and 763 genes have been downregulated in CDK19 knockdown cells (see Table S3 inside the supplemental material). Collectively, this represented an 2-fold reduction inside the variety of genes induced or repressed upon 5-FU therapy. Moreover, GSEA showed lowered enrichment of gene sets in 5-FU-treated shCDK19 cells in comparison with shCTRL cells (versus DMSO controls) (Fig. 5BJuly 2017 Volume 37 Problem 13 e00626-16 mcb.asm.orgAudetat et al.Molecular and Cellular BiologyFIG four SJSA transcriptional response to 5-FU.

The dashed line represents 0.1 FDR cutoff. As expected, tension response (e.g., p53 pathway) gene sets are enriched, whereas proliferative gene sets (e.g., G2/M checkpoint) are lowered in 5-FU treated cells.

As anticipated, 5-FU improved the p53 protein levels in each shCTRL and shCDK19 SJSA cells (Fig. 5D). Expanded analysis of p53 pathway gene induction in shCTRL and shCDK19 cells is shown in Fig. 6A and B (see also Table S5 in the supplemental material), which additional supports altered p53 transcriptional responses in shCDK19 cells. Having said that, it was notable that p53 target genes showed varied effects in shCDK19 cells (versus shCTRL) below basal or stressed (5-FU) circumstances. That is, a subset of p53 pathway genes showed elevated mRNA levels in shCDK19 cells (versus shCTRL) below basal conditionsFIG 5 Transcriptional response to 5-FU is dampened in CDK19 knockdown cells.

In comparison with shCTRL cells (Fig. 4A), the shCDK19 cells show an general decreased transcriptional response.
