Toxicity Profile
Route of ExposureOral, dermal, inhalation, and parenteral (contaminated drugs). (4)
Mechanism of ToxicitySecalonic acid D (SAD) is though to induce cleft palate by causing the formation of smaller palatal shelves that fail to elevate and fuse. This inhibited palatal shelf growth is a result of the of SAD causing reduced proliferation of embryonic palatal mesenchymal (HEPM) cells. SAD binds to and phosphorylates cAMP response element binding protein (CREB), an important transcription factor required for the expression of numerous genes including proliferating cell nuclear antigen (PCNA) gene. The phosphorylation of CREB by SAD prevents it from forming the necessary transcription factor-cAMP response element complex at transcription start sites, so these genes are not expressed. This leads to reduced palatal mesenchymal cell number causing reduced palatal shelf growth and thus cleft palate. (1, 2, 3)
