text: Yo, check it out, here's the deal
  We talking 'bout genome-wide gene expression, for real
  Whole blood be the sample, non-invasive, that's key
  Simple process at the clinical site, you see
  
  We looking for biomarkers, discover the way
  To predict prognosis, diagnose, and even sway
  The response to treatments, therapeutic intervention
  But this tech ain't matured, still needs some attention
  
  Yeah, we had a few wins, but we ain't done yet
  This potential, we gotta fully let it set
  Identifying biomarkers, that's the aim
  But we facing technical problems, it's a shame
  
  One big hurdle, let me break it down
  Them globin transcripts messin' around
  High concentrations, and they variable too
  Non-specific probe binding, makin' it hard to do
  
  Background be high, we need to find a way
  To overcome these obstacles, make it okay
  So in this study, we went deep, we went hard
  Three approaches to detect meaningful cards
  
  Whole blood profiling, that's the name of the game
  Finding those expression patterns, ain't it insane?
  We quantified the power, we took it to the max
  In search of those biological facts
  
  So there you have it, the rap rendition
  Genome-wide gene expression, on a mission
  Biomarkers and blood, we gonna make it right
  Discovering the truth, shining in the clinical light
