          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
          表达水平(P<0.05)。结论  GAA 对子宫肌瘤的改善作用可能涉及 PI3K/AKT、MAPK、TNF 等信号通路;其可通过下调 NDRG1、
          CXCL3蛋白的表达,上调ERRFI1蛋白的表达,影响子宫肌瘤细胞的增殖和凋亡,从而改善子宫肌瘤的发生发展。

          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
