摘要 目的探讨苦参碱抑制前列腺癌进展的机制。方法(1)苦参碱处理PC3和DUl45细胞,高通量测序明确其共同差异基因。(2)共同差异基因行京都基因与基因组百科全书(KEGG)通路分析,选择凋亡相关通路基因并根据癌症和肿瘤基因图谱(TCGA)明确目标基因。(3)实时荧光定量核酸扩增检测系统(RT-qPCR)验证苦参碱对B淋巴细胞瘤-2基因家族成员11(BCL2L11)和生长抑制及DNA损伤诱导基因45B(GADIM5B)表达的影响。(4)设置4组:单纯DUl45细胞组(空白组);GADD45B过表达DUl45细胞组(实验组1);DUl45细胞+苦参碱组(实验组2);GADD45B过表达DUl45细胞+苦参碱组(实验组3)。4组分别利用细胞计数试剂盒(CCK-8)、划痕试验、Transwell试验验证细胞增殖、迁移及侵袭能力,流式细胞术检测细胞凋亡。结果(1)苦参碱处理PC3和DUl45细胞株后,其差异基因共1240个。(2)经筛选,共同差异基因中在两种细胞株中差异趋势相同且与凋亡和前列腺癌预后相关的基因共2个:GADIM5B表达与前列腺肿瘤患者生存率呈正相关(P=0.024),BCL2L1l表达与生存率呈负相关(P=0.015)。(3)苦参碱可以促进DUl45和PC3细胞株GADlM5B(P:0.014,O.002)及BCL2L11(均P=0.000)的表达。(4)苦参碱及过表达的GADD485均可抑制细胞的增殖、迁移和侵袭能力,促进其凋亡。结论苦参碱可以通过促进GADD45B的表达而抑制前列腺肿瘤的进展。 Objective To clarify the mechanism of matrine in the progress of prostate cancer. Methods (1) Gene sequencing identifies the differentially expressed genes between matrine - treated and untreated PC3 and DU145. (2) The apoptotic pathway and prostate cancer related genes were selected ac- cording to Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis and TCGA database. (3) Real - time Quantitative PCR Detecting System ( RT - qPCR) verifies the effect of matrine on the expression of DNA damage inducible beta (GADD45B) and B cell lymphoma/leukemia- 2 (bcl -2) like 11 (BCL2Lll). (4) Set four groups: DU145 (blank, NC), DUI45 + overexpression GADD45B (experi- mental group 1, GADIM5B), DU145 + matrine ( experimental group 2, Matrine) and DU145 + matrine + overexpression GADD45B( experimental group 3, Matrine + GADD45B). Wound healing, cell counting kit - 8 ( CCK-8 ), transwell and flow cytometry experiment were performed to detect the migration, viabil- ity, invasion and apoptosis respectively. Results ( 1 ) There were 1 240 differentially expressed genesbe- tween PC3 and DU145 cell lines after treated withmatrine. (2) 2 of them were related to apoptosis and prostate cancer, in which the expression of GADD45B was positively (P=0. 024 ) while the bcl -2 like 11 ( BCL2LI 1 ) was negatively ( P = 0. 015 ) correlated with the survival rate of patients. ( 3 ) Matrine promo- ted the expression of GAD1M5B ( P = 0. 014 in DU145 ; P = 0. 002 in PC3 ) and BCL2L11 ( P = 0. 000 in two cell lines). (4) Both matrine and GADIM5 could inhibit cell proliferation, migration and invasion, and promote cell apoptosis. Conclusion Matrine inhibits the progression of prostate cancer by promoting the expression of GADD45B.
