If a creature with persist stops being a creature, persist will still work.

07/06/13

If a creature with persist that has +1/+1 counters on it receives enough -1/-1 counters to cause it to be destroyed by lethal damage or put into its owner’s graveyard for having 0 or less toughness, persist won’t trigger and the card won’t return to the battlefield. That’s because persist checks the creature’s existence just before it leaves the battlefield, and it still has all those counters on it at that point.

If a permanent has multiple instances of persist, they’ll each trigger separately, but the redundant instances will have no effect. If one instance returns the card to the battlefield, the next to resolve will do nothing.

07/06/13

When a permanent with persist returns to the battlefield, it’s a new object with no memory of or connection to its previous existence.

01/08/08

If a nontoken creature that gains persist this way is put into a graveyard, that card will be returned to the battlefield with a -1/-1 counter on it. However, because it’s a new object with no relation to its previous existence, that permanent will not have persist.
