Repeated administration of lysergic acid diethylamide (LSD) to mice over seven days altered DNA methylation at 635 sites and changed the expression of 178 proteins in the prefrontal cortex. The affected genes and proteins are involved in nervous system development, axon guidance, synaptic plasticity, and cell viability. Four specific genes—Coro7, Pef1, Rps24, and Abhd6—showed both increased methylation and increased transcription. These results suggest that LSD modifies epigenetic and protein-expression pathways related to neuroplasticity, which may underlie its therapeutic effects in mental disorders.
