Interestingly, knockdown of HSF in the prothoracic gland (PG), an organ that synthesizes the hormone ecdysone, caused larvae arrest at the third instar stage without pupariation. The arrest was rescued by raising the animals on ecdysone-containing media, suggesting that those larvae cannot produce enough ecdysone.
