WebNov 12, 2024 · What does it mean for a gene set to have a small nominal p value (p<0.025), but a high FDR value (FDR=1)? The nominal p value estimates the significance of the observed enrichment score for a single gene set. However, when you are evaluating multiple gene sets, you must correct for multiple hypothesis testing. The FDR is the … WebStatistical methods are used to select for the significant differential expression of genes in RNA-seq and microarray experiments but most previous study performed FDR (0.1, 0.05 and 0.01) and ...

The purple lines indicate regions where these genes are statistically enriched, compared to the density of genes in the background. We scanned the genome with a sliding window. Each window is further divided into several equal-sized steps for sliding.
Downregulation or upregulation of an RNA or protein may also arise by an epigenetic alteration. Such an epigenetic alteration can cause expression of the RNA or protein to no longer respond to an external stimulus. This occurs, for instance, during drug addiction or progression to cancer .
