Impact of “shipping delay” on global gene expression. a Unsupervised hierarchical clustering showing separation into two distinct clusters. In-house samples colored in blue, shipped samples colored in green. b Volcano plot showing differential gene expression between 139 in-house and 252 shipped samples of the GMMG MM5 trial. The left-hand spread shows down-regulated genes in shipped samples. The right-hand spread shows the up-regulated genes. The color of each point reflects the log2 fold change (logFC) for the respective gene with absolute logFC <1 depicted in black, ≥ 1 & <2 in blue, and ≥ 2 in red. We added the gene symbol, if the absolute logFC was >3
