目的
2
本研究旨在阐明赖氨酸特异性脱甲基酶 1(lysine specific demethylase 1,LSD1)在去势抵抗性前列腺癌(prostate cancer,PCa)中的作用及分子机制。
方法
2
通过利用癌症基因组图谱(The Cancer Genome Atlas,TCGA)数据库进行生物信息学分析,探索LSD1在PCa中的差异表达和预后情况;为了构建雄激素非依赖性(androgen-independent,AI)细胞系,对PCa雄激素依赖细胞系前列腺癌淋巴结转移细胞系(lymph node carcinoma of the prostate cells,LNCap)进行雄激素剥夺处理,敲低LSD1观察细胞变化,并用LSD1抑制剂处理雄激素非依赖前列腺癌PC-3细胞系(Prostate Cancer-3 cell line,PC-3);构建PCa原位瘤模型探究LSD1抑制对去势治疗敏感性的影响;最后通过转录组测序、实时荧光定量聚合酶链式反应(real-time fluorescence quantitative PCR,qPCR)和蛋白质印迹技术(Western blot,WB)和染色质免疫沉淀(chromatin immunoprecipitation,ChIP)实验探索机制。
结果
2
LSD1在TCGA-PCa及去势抵抗性PCa中明显上调,高表达患者生存期短,且在LNCap-AI细胞中表达高于LNCap细胞,敲低LSD1可抑制细胞恶性行为、提高凋亡水平,LSD1抑制剂能抑制PC-3细胞恶性行为,抑制LSD1可提高PCa对去势治疗的敏感性,LSD1敲低降低基质金属蛋白酶13(Matrix Metalloproteinase 13,MMP13)的表达、抑制白细胞介素-17(interleukin-17,IL-17)信号通路,并通过调节MMP13基因启动子区域组蛋白H3第9位赖氨酸(histone H3 lysine 9,H3K9)的甲基化水平调控其表达。
结论
2
LSD1通过调节MMP13基因启动子区域H3K9的甲基化水平控制MMP13表达,进而影响IL-17信号通路,在前列腺癌去势抵抗性进程中发挥重要作用。
Objective
2
This study aimed to elucidate the role and molecular mechanism of lysine specific demethylase 1(LSD1) in castration-resistant prostate cancer(PCa).
Methods
2
Bioinformatics analysis was conducted using The Cancer Genome Atlas(TCGA) database to explore the differential expression and prognostic significance of LSD1 in PCa. An androgen-independent(AI) cell line was established by subjecting the androgen-dependent LNCap cell line of PCa to androgen deprivation. The effects of LSD1 knockdown on cell characteristics were observed,and the androgen-independent PC-3 cells were treated with the LSD1 inhibitor. A PCa orthotopic tumor model was constructed to investigate the impact of LSD1 inhibition on the sensitivity of PCa to castration therapy. Finally,transcriptome sequencing,real-time fluorescence quantitative PCR(qPCR),Western blot,and chromatin immunoprecipitation (ChIP) assays were performed to explore the underlying mechanisms.
Results
2
LSD1 was significantly upregulated in TCGA-PCa and castration-resistant PCa. Patients with high LSD1 expression had shorter survival times. The expression of LSD1 was higher in LNCap-AI cells compared to LNCap cells. LSD1 knockdown inhibited the malignant behavior of cells and increased apoptosis. The LSD1 inhibitor suppressed the malignant behavior of PC-3 cells. Inhibition of LSD1 enhanced the sensitivity of PCa to castration therapy. Mechanistically,LSD1 knockdown decreased the expression of Matrix Metalloproteinase 13(MMP13) and inhibited the interleukin-17(IL-17) signaling pathway. LSD1 regulated the expression of MMP13 by modulating the methylation level of the H3K9 region in the MMP13 gene promoter.
Conclusion
2
LSD1 controls the expression of MMP13 by regulating the methylation level of the H3K9 region in the MMP13 gene promoter,thereby influencing the IL17 signaling pathway and playing a crucial role in the progression of castration resistance in prostate cancer.
