Fig. 2: Transcriptional signatures of ketamine responders vs. non-responders at baseline.

a Volcano plots showing significantly (p < 0.05, fold change > or <1.3) differentially expressed genes (DEG) [red = upregulated and blue = downregulated]. Gene names are indicated for the top 25 differentially expressed protein-coding genes. b Ingenuity Pathway Analysis (IPA) identified two biological pathways (red = activation) enriched at baseline in responders vs. non-responders. c DEGs within each pathway. d Predicted upstream regulators identified by IPA (red indicates predicted activation, blue indicates predicted inhibition).
