目的 通過網(wǎng)絡(luò)藥理學(xué)探討柴胡皂苷a在抑郁癥治療中的作用機(jī)制。方法 從PubChem、PharmMapper和SwissTarget Prediction數(shù)據(jù)庫(kù)中獲取柴胡皂苷a的分子結(jié)構(gòu)和潛在靶點(diǎn)。將柴胡皂苷a和抑郁癥的共同靶點(diǎn)導(dǎo)入STRING 11.0數(shù)據(jù)庫(kù)，構(gòu)建蛋白相互作用（PPI）網(wǎng)絡(luò)。利用DAVID 6.8數(shù)據(jù)庫(kù)進(jìn)行基因本體論（GO）和京都基因與基因組百科全書（KEGG）富集分析。結(jié)果 本研究共獲得柴胡皂苷a靶點(diǎn)408個(gè)，抑郁相關(guān)靶點(diǎn)3 799個(gè)，最終得到200個(gè)共同靶點(diǎn)，包括白蛋白（ALB）、絲氨酸/蘇氨酸蛋白激酶B（Akt1）、熱休克蛋白90 α家族A類成員1（HSP90AA1）、轉(zhuǎn)錄信號(hào)轉(zhuǎn)導(dǎo)和激活因子3（STAT3）和表皮生長(zhǎng)因子受體（EGFR）等。GO和KEGG富集分析表明，癌癥、脂質(zhì)和動(dòng)脈粥樣硬化、前列腺癌、癌癥蛋白多糖、內(nèi)分泌耐藥、叉頭框-O（FoxO）信號(hào)通路、磷酸肌醇-3激酶（PI3K）/Akt信號(hào)通路、EGFR酪氨酸激酶抑制劑耐藥、Th17細(xì)胞分化、催乳素信號(hào)通路等通路在柴胡皂苷a抗抑郁中發(fā)揮了重要作用。結(jié)論 柴胡皂苷a可能通過作用于FoxO、催乳素、PI3K/Akt信號(hào)通路及ALB、Akt1、HSP90AA1、STAT3等靶點(diǎn)發(fā)揮抗抑郁作用。

Objective To elucidate the mechanism of saikosaponin a in treating depression with network pharmacology. Methods Molecular structure and potential targets of saikosaponin a was obtained from PubChem, PharmMapper and SwissTarget Prediction databases. The common targets of saikosaponin a and depression were imported to the STRING 11.0 database, and then a protein interaction network was constructed. GO and KEGG enrichment were analyzed with DAVID 6.8 database.Results A total of 408 targets of saikosaponin a were obtained and there were 3 799 depression-related targets. A total of 200 common genes were selected as targets of depression including ALB, Akt1, HSP90AA1, STAT3, and EGFR. GO and KEGG analysis suggested that pathways in cancer, lipid and atherosclerosis, prostate cancer, proteoglycans in cancer, endocrine resistance, FoxO signaling pathway, PI3K/Akt signaling pathway, EGFR tyrosine kinase inhibitor resistance, Th17 cell differentiation, and prolactin signaling pathway played an imported role. Conclusion Our results suggested that saikosaponin a may exert its antidepressant effect by acting on FoxO, prolactin, and PI3K/Akt signaling pathways and ALB, Akt1, HSP90AA1, and STAT3 targets.
