1 Vvl and Kni bind to PG specific cis-regulatory elements that are required for expression of the ecdysone biosynthetic genes. Ecdysone ventral veins lacking Drosophila melanogaster
2 Knock down of either vvl or kni in the PG results in a larval developmental arrest due to failure in ecdysone production. Ecdysone ventral veins lacking Drosophila melanogaster
3 Furthermore, Vvl and Kni are also required for maintenance of TOR/S6K and prothoracicotropic hormone (PTTH) signaling in the PG, two major pathways that control ecdysone biosynthesis and PG cell growth. Ecdysone ventral veins lacking Drosophila melanogaster
4 Our data show that Vvl and Kni directly regulate ecdysone biosynthesis by transcriptional control of biosynthetic gene expression and indirectly by affecting PTTH and TOR/S6K signaling. Ecdysone ventral veins lacking Drosophila melanogaster
