Objective:To investigate the molecular mechanism and identify potential drugs for subthreshold depression(SD),and elucidate the detalied mechanism of Danzhi Xiaoyao powder(DZXY)in SD.Methods:Using RNA-sequencing,we identified differentially expressed genes(DEGs)in leukocytes of SD compared to healthy controls,deciphered their functions and pathways,and identified the hub genes of SD.We also assessed changes in leukocyte transcription factor activity in patients with SD using the TELiS platform.The Connectivity Map database was retrieved to screen candidate drugs for SD.Based on network pharmacology,we elucidated the"multi-component,multi-target,and multi-pathway"mech-anism of DZXY in the treatment of SD.Results:We identified 1080 DEGs(padj＜0.05 and |log2(fold change)| ≥ 1 & protein coding)in the leukocytes of patients with SD.These DEGs,including hub genes,were primarily involved in immune and inflammatory response-related processes.Transcription factor activity analysis revealed similarities be-tween the leukocyte transcriptome profile in SD and the conserved transcriptional response to adver-sities in immune cells.Connectivity Map analysis identified 28 potential drugs for SD treatment,particularly SB-202190 and TWS-119.Constructing the"Direct Compounds-Direct Targets-Pathways"network for DZXY and SD revealed the curative mechanisms of DZXY in SD,primarily including in-flammatory response,lipid metabolism,immune response,and other processes.Conclusion:These results provide new insights into the characteristics and functional changes of leu-kocytes in SD,partially illustrate the pathogenesis of SD,and suggest potential drugs for SD.The curative mechanisms of DZXY in SD are also partially elucidated.
