text: Yo, listen up, I got some knowledge to drop,
  About p63 and p53, let the beat go pop.
  They're homologues, but p63's unique,
  Mutations in tumors? Nah, they're rarely seen, speak!
  
  In cell differentiation, p63 takes the lead,
  A regulatory role, that's what we need.
  But when it comes to tumors, it's still unclear,
  What role p63 plays, gotta make it clear.
  
  This study aimed to compare the expressions,
  Of p63 and p53, check their impressions.
  Malignant melanomas, tissue microarrays,
  Looking for prognostic significance, gotta blaze!
  
  Out of 59 tumors, p63 was seen in just two,
  Both pT4, that's the clue.
  The p63 index, didn't go beyond thirty,
  But p53 was present, in a whole lotta plenty.
  
  27 melanomas showed p53 expression,
  Up to 80% of cells, that's the confession.
  No correlations between these two markers,
  Multivariate analysis, the prognosis sparks.
  
  Confirmed the independent role of p53,
  In the game of tumors, it's the key.
  Tissue microarrays came through strong,
  Evaluating tumor markers, they belong.
  
  So there you have it, the study's conclusion,
  P63 and p53, causing some confusion.
  But with tissue microarrays, we got a tool,
  To understand tumors, and break the rule.
