text: Yo, check it out, here's the deal,
  V1b vasopressin receptors, let me keep it real.
  In the anterior pituitary, they play a role,
  When stress hits the scene, they take control.
  
  Hypothalamic-pituitary-adrenal axis, that's the game,
  Rats adapt to stress, ain't it insane?
  V1bR expression, transcriptional and translational,
  Regulation's the key to this whole situation.
  
  GAGA repeats, that's the name of the game,
  GAGA box in the promoter, where things get tame.
  Protein complex of 127 kDa, they bind,
  Pituitary nuclear extracts, they unwind.
  
  V1bR mRNA, VP binding sites don't align,
  Translation efficiency, that's where it shines.
  5'-UTR, the untranslated region's the key,
  Inhibition or activation, that's how it'll be.
  
  Upstream open reading frames, they repress,
  Translation of the major ORF, I must confess.
  But hold up, there's more, an IRES in sight,
  Activating V1bR translation, shining bright.
  
  Protein kinase C-mediated pathways in the mix,
  IRES activity stimulated, that's the fix.
  V1bR mRNA translation, protein levels rise,
  Plasticity of regulation, it's no surprise.
  
  Multiple loci of regulation, at every turn,
  Transcriptional and translational, that's how we learn.
  Pituitary vasopressin receptors, they demand,
  Regulation's the key, it's all part of the plan.
