我们利用甲虫酯的高比活性光亲和类似物 [3H]-甲虫酯重氮酮 (MDK) 来研究 29 kDa 保幼激素 (JH) 结合蛋白的发育表达和激素调节。在摄食的第 4 龄和第 5 龄幼虫的表皮中检测到 29 kDa MDK 结合蛋白,但在蜕皮至第 5 龄和蛹期间丰度下降。在第 1 天的蛹表皮中也检测到了这种蛋白质。在 2 × 10−6 M 20-羟基蜕皮酮 (20HE) 存在下培养第 2 天的 5 龄幼虫体皮,导致 29 kDa MDK 结合蛋白减少三倍。 3 × 10−6 M JH I 的存在阻止了这种损失。在幼虫蜕皮的 JH 关键期后,对蜕皮的第 4 龄幼虫进行脱毛,导致 25 小时后分离的表皮中或从第 1 天的第 5 龄幼虫或第 1 天的蛹中分离出 29 kDa MDK 结合蛋白。在剥皮时以及此后每 12 小时应用 5 μ JH I 或甲虫平,直到需要进行解剖才能在第 1 天 5 龄幼虫表皮中存在该蛋白质。在游走当天和第二天施用 5 μg JH I 导致 29 kDa MDK 结合蛋白出现在由无乳腺幼虫形成的第 1 天蛹的表皮中。
We have utilized a high specific activity photoaffinity analog of methoprene, [3H]-methoprene diazoketone (MDK), to study the developmental expression and hormonal regulation of the 29 kDa juvenile hormone (JH)-binding protein. The 29 kDa MDK-binding protein was detected in the epidermis of the feeding 4th and 5th instar larvae but decreased in abundance during the molts to the 5th instar and the pupa. This protein was also detected in day 1 pupal epidermis. Culturing of day 2 5th instar larval integument in the presence of 2 × 10−6 M 20-hydroxyecdysone (20HE) caused a threefold decrease in the 29 kDa MDK-binding protein. Presence of 3 × 10−6 M JH I prevented this loss. Allatectomy of molting 4th instar larvae after the critical period for JH for a larval molt resulted in the absence of the 29 kDa MDK-binding protein in epidermis isolated 25 hr later or from either day 1 5th instar larvae or day 1 pupae. Application of 5 μ of JH I or methoprene at the time of allatectomy and every 12 hr thereafter until dissection was necessary for the presence of this protein in day 1 5th instar larval epidermis. Application of 5 μg of JH I on the day of wandering and the next day caused the appearance of the 29 kDa MDK-binding protein in the epidermis of day 1 pupae formed by allatectomized larvae.
