白蚁等级分化需要激素调节，但对蜕皮激素的作用了解有限。在这里，我们研究蜕皮激素相关基因的表达和功能在湿木白蚁内华达州动物白蚁士兵分化。蜕皮激素受体基因（EcR）在蜕皮前期的头部有高表达。敲低EcR的表达，在早期presoldier期间抑制蜕皮成士兵。然而，在中期敲低影响酪氨酸代谢基因的表达，抑制特定的表皮晒黑。这些结果表明，蜕皮激素激活参与特定的表皮形成。
Termite caste differentiation requires hormonal regulation, but understanding of the role of ecdysone is limited. Here, we investigated the expression and function of ecdysone-related genes during soldier differentiation in the damp-wood termite Zootermopsis nevadensis. Ecdysone receptor gene (EcR) was highly expressed in the head just after the presoldier molt. Knockdown of EcR expression in the early presoldier period inhibited the molts into soldiers. However, knockdown in the middle period affected tyrosine metabolic gene expression and inhibited soldier-specific cuticular tanning. These results suggest that ecdysone activation is involved in soldier-specific cuticle formation.
