Article Synopsis
- - The neuropeptide prothoracicotropic hormone (PTTH) regulates ecdysone synthesis critical for insect metamorphosis, while pyriproxyfen, a juvenile hormone analogue, disrupts this process in silkworms.
- - RNA-seq analysis revealed 3,774 differentially expressed genes in the prothoracic gland after pyriproxyfen exposure, primarily affecting the MAPK signaling pathway linked to PTTH.
- - Increased PTTH levels were observed, but downstream signaling genes (like torso and ERK) were down-regulated, indicating that pyriproxyfen interferes with metamorphosis by impairing PTTH-Torso signaling.
