20E Hormone Drives Developmental Shifts via BR-C Enhancer Accessibility

Swift Summary:

• The study published in the proceedings of the national Academy of Sciences, Volume 122, Issue 32 (August 2025) investigates gene regulation mechanisms in Drosophila.
• It examines how histone modifications and transcription factors work together to regulate gene expression.
• In Drosophila wing discs lacking juvenile hormone (JH) signaling, researchers found that the hormone 20-hydroxyecdysone (20E) directly induces expression of the gene Kr-h1.
