Fig. 4. Tumor Evolution of Sequenced Samples.
a Flowchart representing study samples sent for OBP. b Table summarizing tissue timepoint for all AI and fulvestrant samples passing OBP. c Enriched gene sets for differentially expressed genes between different timepoints using paired samples from the same patients. Log2 fold-change are calculated using DESeq2 in the paired mode setting and used as ranked gene list for input to GSEA. The normalized enrichment score (NES) along with associated p values are used to generate this bubble plot. d GSEA enrichment plots for select gene sets under each of the three timepoint comparisons. e Heatmap depicting gene expression fluctuations for select genes under different functional groups during the course of therapy. f Multispectral immunofluorescence imaging of a paired pretreatment and on-treatment sample.
