RNAseq analysis on serial sample

Hi all,

I am new to RNA-seq analysis. I have data from RNA-seq performed on serial samples (before treatment, after treatment 1, after treatment 2) from 3 biological replicates (3 different patients). I was able to use DESeq2 in order to obtain the top differentially expressed gene sets. Since patients samples can be highly heterogeneous, I would also like to analyze the serial samples from each patient individually only for exploratory purpose. What is the best way to do that?

Since patients samples can be highly heterogeneous

Have you analyzed that? How different/divergent they are? You can plot a PCA from your normalized raw counts to visualize it.

I was hoping that the samples would align based on clinical response, but the samples group by biological sample.

Couldn't you use 2 grouping variables and results(..., contrast = ) based on what you need?

ImpulseDE is a good way of analyzing time series samples. It gives you the genes that are going down, up or having a transient response.
