text: Yo, listen up, let me break it down
  Primary hyperparathyroidism, it's goin' around
  Enlarged glands, excessive PTH secretion
  That's the cause, it's a gland disorder, no deception
  
  But the mechanism behind this tumor growth
  It's a mystery, we don't know, we need some truth
  So we dug deep, investigated and explored
  TGF-beta and menin, let's see what they hold
  
  TGF-beta, it's present in the cells
  Of the parathyroid, where the story dwells
  Added to cells from secondary hyperparathyroidism
  It said, "Hold up, stop the growth, inhibit the system"
  
  Not just that, it also suppressed PTH release
  But when menin was inactivated, the effect deceased
  Men1 gene, it's the culprit, you see
  Without menin, TGF-beta couldn't set the cells free
  
  But here's the twist, for a Men1 patient it's different
  TGF-beta didn't affect, it wasn't significant
  So we conclude, TGF-beta plays a role
  In regulating parathyroid growth and PTH control
  
  Loss of TGF-beta due to menin's inactivation
  Leads to tumorigenesis, that's the implication
  So now we know, the rap's complete
  TGF-beta and menin, they're the ones we gotta treat
