摘 要 目的 研究醋酸棉酚(GAA)治疗子宫肌瘤的作用机制。方法 以人子宫肌瘤细胞SK-UT-1为研究对象,考察不同质量浓
度(5、10、20、40、80、160 μmol/L)GAA对细胞增殖活性的影响;结合四维数据非依赖型采集(4D-DIA)蛋白组学技术和生物信息学
分析筛选差异蛋白,并进行基因本体(GO)分析和京都基因与基因组百科全书(KEGG)信号通路分析;检测SK-UT-1细胞中差异
倍数排前 3 名的蛋白[N-myc 下游调节基因 1(NDRG1)、表皮生长因子受体反馈抑制剂 1(ERRFI1)、CXC 趋化因子配体 3
(CXCL3)]的表达水平。结果 10~160 μmol/L的GAA可显著降低细胞存活率(P<0.05)。蛋白组学结果显示,共获取了921个差
异蛋白,其中上调蛋白254个、下调蛋白667个,差异蛋白主要分布在线粒体、细胞核、细胞外基质等。生物信息学结果显示,差异
蛋白涉及的信号通路主要有PI3K/AKT(磷脂酰肌醇3激酶/蛋白激酶B)、MAPK(促分裂原活化的蛋白质激酶)、TNF(肿瘤坏死因
子)等,主要涉及细胞凋亡、衰老、运动。GAA可显著下调细胞中NDRG1、CXCL3蛋白表达水平(P<0.05),显著上调ERRFI1蛋白

ABSTRACT OBJECTIVE To investigate the mechanism of gossypol acetic acid (GAA) in the treatment of uterine fibroids.
METHODS Human leiomyoma cells SK-UT-1 were selected as objects to investigate the effects of different concentrations (5, 10,
20, 40, 80, 160 μmol/L) of GAA on the activities of cell proliferation. 4D-DIA proteomic detection and bioinformatics analysis
were carried out to screen differential proteins. Gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes
(KEGG) signaling pathway analysis were performed. The expressions of top 3 proteins [N-myc downstream regulated gene 1
(NDRG1), epidermal growth factor receptor feedback inhibitor 1 (ERRFI1), CXC chemokine ligand 3 (CXCL3)] with differential
fold changes in SK-UT-1 cells were determined. RESULTS 10-160 μmol/L GAA could significantly reduce the survival rate of SK-
UT-1 cells (P<0.05). Proteomics results showed that a total of 921 differentially expressed proteins were obtained, including 254
up-regulated proteins and 667 down-regulated proteins. The differentially expressed proteins were mainly distributed in
mitochondria, nucleus, extracellular matrix, etc. Bioinformatics results showed that differentially expressed proteins were mainly
involved in signaling pathways such as PI3K/AKT (phosphoinositide 3-kinase/protein kinase B), MAPK (mitogen-activated protein
kinase), TNF (tumor necrosis factor), etc., which mainly involved cell apoptosis, aging, and movement. GAA significantly
decreased protein expressions of NDRG1 and CXCL3 (P<0.05), but increased protein expression of ERRFI1 (P<0.05).
CONCLUSIONS The improvement effect of GAA on uterine
