9. Apply it to tanning
When DNA is damaged by UV, a gene called p53 is activated (mechanism unknown)
The p53 protein, in turn, activates a gene called POMC
POMC causes another molecule to break apart and create MSH (melanin stimulating hormone)
This hormone causes the cell to turn tyrosine into melanin
In a nutshell – UV damage causes a gene to be activated, which in turn activates melanin production
