Which information can be extracted from time course RNA-Seq Data?
It can be complicated because RNA-seq data is looking at gene expression, in the form of mRNA. But there are thousands of housekeeping genes that are expressed constantly, as long as an organism is alive. So the real interesting genes in a time course are those that are differentially expressed. So gene 1, in your example is not that interesting. Gene 2 however shoes a 4-fold increase between day 50 and day 100. Still, that is not that huge. You need computer programs to sort all this out. But what you want is to be able to associate a huge change in mRNA (gene expression) that can be distinguished from background.
