text: Yo, listen up, here's a scientific revelation,
  About inostamycin and its cellular relation.
  This inhibitor be stoppin' cell proliferation,
  In NRK cells, disruptin' G1 phase activation.
  
  Now check it, we got some new data to bring,
  'Bout the effect of inostamycin on protein kinases in the ring.
  When serum comes knockin' at NRK's door,
  MAP kinase and casein kinase II hit the floor.
  
  But hold up, inostamycin ain't messin' with those guys,
  They stay active, no matter how hard it tries.
  But here's the deal, CDK2 takes a fall,
  Can't get activated when inostamycin calls.
  
  And yo, that's not all, cyclin E gets suppressed,
  Inostamycin shuts it down, it's unimpressed.
  Cyclin D1 expression, it inhibits too,
  Messin' with pRB phosphorylation, that's what it'll do.
  
  So inostamycin brings the early G1 arrest,
  Blockin' cyclin D1 and E, that's the best.
  Now you know the science, the facts are laid bare,
  Inostamycin's impact on NRK cells, so rare.
