Cultured Drosophila melanogaster cells are responsive to the steroid hormone 20-hydroxyecdysone (ecdysterone). The transcripts of two copia-like transposable elements, 412 and 1731 were examined in cells treated for different lengths of time by the hormone. Using dot-blot and Northern-blot analysis, we have shown that the transcripts of these two retrotransposons were rapidly decreased by ecdysterone treatment.
培养的黑腹果蝇细胞对类固醇激素20-羟基蜕皮激素（蜕皮甾酮）有反应。在经该激素处理不同时长的细胞中，检测了两个类copia转座元件412和1731的转录本。通过斑点印迹和Northern印迹分析，我们发现这两个逆转座子的转录本在蜕皮激素处理后迅速减少。
