谷氨酸靶向治疗白血病研究进展
2025/11/01·StepFun can make mistakes, check important info.
科学家在2025年4月发现谷氨酸有望成为急性白血病治疗的新靶点,通过阻断谷氨酸的合成或其转运蛋白SAUT的功能,能显著抑制白血病的进展。在小鼠模型中,通过基因工具敲除CN07(谷氨酸合成的关键酶)或SAUT就能显著延长小鼠的生存时间。更令人振奋的是,使用SAUT抑制剂处理人类白血病细胞样本也能显著减少白血病细胞的生长和克隆形成能力。这些实验结果为白血病治疗带来了新希望。

In addition to its bioenergetic role in leukemia cell proliferation, L‐glutamate is a neurotransmitter that acts on glutamate receptors. However, the role of glutamate receptors in AML is largely understudied. Here, we comprehensively analyze the genomic and transcriptomic alterations of glutamate receptor genes in AML using publicly available data. We investigated the frequency of mutations in the glutamate receptor genes and whether an association exist between the presence of these mutations and clinical and molecular characteristics or patient's clinical outcome. We also assessed the dysregulation of glutamate receptor gene expression in AML with and without mutations and whether gene dysregulation is associated with clinical outcomes. We found that 29 (14.5%) of 200 patients with AML had a mutation in at least one glutamate receptor gene. The DNMT3A mutations were significantly more frequent in patients with mutations in at least one glutamate receptor gene compared with patients without mutations (13 of 29 [44.8%] vs. 41 of 171 [23.9%], p value: 0.02). Notably, patients with mutations in at least one glutamate receptor gene survived shorter than patients without mutations; however, the results did not reach statistical significance (overall survival: 15.5 vs. 19.0 months; p value: 0.10).

The discovery of more effective therapeutic strategies for AML plays a crucial role. The present work showed that E35, a novel derivative of emodin, significantly inhibited cell proliferation and induced autophagy and apoptosis in AML cells. Treatment with E35 markedly induced Beclin-1, LC3-II, cleaved Caspase-9 and PARP, and suppressed mitogen-activated protein kinase (MAPK) pathway. E35 exposure evoked autophagic activity prior to apoptosis induction, and autophagy inhibition by 3-methyladenine (3-MA) dramatically increased E35-induced apoptosis in both AML cell lines and patient-derived AML cells. Nevertheless, study on AML xenograft model showed that the combination E35 with 3-MA exhibited much more inhibitory effects on leukemia cell growth in vivo. No obvious adverse reactions occurred in the xenograft animals administered E35 alone or its cotreatment with 3-MA. These findings suggest that E35 could exert anti-leukemia effects, and that the combination of E35 and autophagy inhibitor might prove a more highly efficient strategy for AML treatment.

【摘要】: 神经胶质瘤细胞主要依赖谷氨酸/胱氨酸转运体(glutamate/cystine antiporter, xc-)摄取胱氨酸合成谷胱甘肽(GSH),维持细胞的抗氧化能力。 本研究以神经胶质瘤C6细胞、原代培养的星形胶质细胞和常常被作为神经元模型的嗜铬细胞瘤PC-12细胞为研究对象,观察谷氨酸/胱氨酸转运体抑制剂—柳氮磺吡啶(SAS)对三种细胞存活率的影响,进一步探讨不同类型的氧化剂对SAS抑制细胞增殖作用的影响及其机制,通过分析谷氨酸/胱氨酸转运体在肿瘤形成中的作用,为神经胶质瘤的治疗提供理论基础。 本实验证明了相对于原代培养的星形胶质细胞和神经元,谷氨酸/胱氨酸转运体抑制剂SAS对C6细胞增殖的抑制作用较强,呈剂量依赖性,表明SAS对C6细胞增殖具有特异性的抑制作用。 其次,SAS分别与维生素K3(VK_3)或过氧化氢(H_2O_2)同时添加,通过以下机制抑制细胞增殖:(1)使xCT表达降低,内源性导致合成GSH的原料—胱氨酸缺乏; (2)通过使C6细胞内活性氧增多,外源性导致细胞内原有的GSH进一步消耗增多; (3)抑制GSH合成的限速酶—谷氨酸半胱氨酸连接酶(GCL)亚单位GCLC、GCLM的表达,内源性导致C6细胞内新的GSH合成受限,引起C6细胞内的GSH含量下降;

机译: 对谷氨酰胺剥夺具有抗性的白血病细胞表达谷氨酰胺合成酶蛋白 摘要 Objective: Low glutamine levels have been shown in tumor environments for several cancer subtypes. Therefore, it has been suggested that cancer cells rewire their metabolism to adopt low nutrient levels for survival and proliferation. Although glutamine is a non-essential amino acid and can be synthesized de novo, many cancer cells including malignant hematopoietic cells have been indicated to be addicted to glutamine. This study aimed to investigate the proliferation of leukemia cell lines in glutamine-deprived conditions. Materials and Methods: Cell proliferation of K562, NB-4, and HL-60 cells was determined by calculating cell numbers in normal vs. low glutamine media. Changes in mRNA expressions were investigated using qRT-PCR. The glutamine synthetase (GS)-encoding GLUL gene was knocked out (KO) in HL-60 cells using the CRISPR/Cas9 method and protein expression was evaluated with immunoblotting. Results: The proliferation of all cell lines was decreased in glutamine-deprived medium. GS protein expression was increased in glutamine-limited medium although the mRNA level did not change. Increased protein expression was confirmed with inhibition of new protein synthesis by treating cells with cycloheximide. To further investigate the role of GS protein, the GS-encoding GLUL gene was KO in HL-60 cells using the CRISPR/Cas9 method. GS KO cells proliferated less compared to control cells in glutamine-limited medium. Conclusion: Our results i

机译: 目的:在肿瘤环境中,几种癌症亚型的谷氨酰胺水平较低。因此,有人建议癌细胞重新连接其新陈代谢,以采用低营养水平来生存和增殖。虽然谷氨酰胺是一种非必需氨基酸,可以从头合成,但许多癌细胞(包括恶性造血细胞)已被证明对谷氨酰胺上瘾。本研究旨在研究谷氨酰胺剥夺条件下白血病细胞系的增殖。材料和方法:通过计算正常与低谷氨酰胺培养基中的细胞数来确定 K562、NB-4 和 HL-60 细胞的细胞增殖。使用qRT-PCR研究mRNA表达的变化。使用 CRISPR/Cas9 方法敲除 (KO) 在 HL-60 细胞中敲除 (GS) 编码的谷氨酰胺合成酶 (GS) 基因,并通过免疫印迹评估蛋白质表达。结果:在谷氨酰胺剥夺培养基中,所有细胞系的增殖均降低。尽管 mRNA 水平没有变化,但 GS 蛋白在谷氨酰胺限制性培养基中的表达增加。通过用环己酰亚胺处理细胞来抑制新的蛋白质合成,证实了蛋白质表达的增加。为了进一步研究GS蛋白的作用,使用CRISPR/Cas9方法在HL-60细胞中KO编码GS的GLUL基因。与对照细胞相比,GS KO细胞在谷氨酰胺限制性培养基中的增殖更少。结论:GS蛋白表达上调是白血病细胞系谷氨酰胺成瘾的原因。利用负责GS蛋白表达的遗传和代谢机制可以确定新的抗癌药物靶点。

Abstract Acute myeloid leukemia (AML) is a blood cancer that is poorly responsive to conventional cytotoxic chemotherapy and a diagnosis of AML is usually fatal. More effective and better-tolerated therapies for AML are desperately needed. Activating mutations in FMS-like tyrosine kinase 3 (FLT3) are one of the most frequently observed genetic defects in AML. FLT3 inhibitors have shown impressive anti-leukemic activity in clinical trials; however, sustained remissions using these inhibitors as monotherapy have not been achieved. Our previous studies have implicated impaired glutamine metabolism in response to FLT3 inhibitors as a dominant factor causing AML cell death. In this study, we have employed metabolic flux analysis to examine the effects of FLT3 inhibition on glutamine utilization in FLT3-mutated AML cells using stable isotope tracers. We found that the FLT3 inhibitor AC220 inhibited glutamine flux into the antioxidant factor glutathione profoundly due to defective glutamine import. We also found that the glutaminase inhibitor CB-839 similarly impaired glutathione production by effectively blocking flux of glutamine into glutamate. Moreover, the combination of AC220 with CB-839 synergized to deplete glutathione, induce mitochondrial reactive oxygen species, and cause loss of viability through apoptotic cell death. In vivo, glutaminase inhibition with CB-839 facilitated leukemic cell elimination by AC220 and improved survival significantly in a patient-derived xenogra

机译: 急性髓系白血病中谷氨酸受体的基因组学和转录组学改变 摘要 Glutamine and glutamate have been widely explored as potential therapeutic targets in acute myeloid leukemia (AML). In addition to its bioenergetic role in leukemia cell proliferation, L‐glutamate is a neurotransmitter that acts on glutamate receptors. However, the role of glutamate receptors in AML is largely understudied. Here, we comprehensively analyze the genomic and transcriptomic alterations of glutamate receptor genes in AML using publicly available data. We investigated the frequency of mutations in the glutamate receptor genes and whether an association exist between the presence of these mutations and clinical and molecular characteristics or patient's clinical outcome. We also assessed the dysregulation of glutamate receptor gene expression in AML with and without mutations and whether gene dysregulation is associated with clinical outcomes. We found that 29 (14.5%) of 200 patients with AML had a mutation in at least one glutamate receptor gene. The DNMT3A mutations were significantly more frequent in patients with mutations in at least one glutamate receptor gene compared with patients without mutations (13 of 29 [44.8%] vs. 41 of 171 [23.9%], p value: 0.02). Notably, patients with mutations in at least one glutamate receptor gene survived shorter than patients without mutations; however, the results did not reach statistical significance (overall survival: 15.5 vs. 19.0 months; p value: 0.10). Mutations in the glutamate receptor

机译: 大黄素衍生物 E35 及其与自噬抑制剂联合治疗急性髓系白血病细胞的体外和体内 摘要 Acute myeloid leukemia (AML) is an aggressive hematopoietic malignancy with poor prognosis and high recurrence rate. The discovery of more effective therapeutic strategies for AML plays a crucial role. The present work showed that E35, a novel derivative of emodin, significantly inhibited cell proliferation and induced autophagy and apoptosis in AML cells. Treatment with E35 markedly induced Beclin-1, LC3-II, cleaved Caspase-9 and PARP, and suppressed mitogen-activated protein kinase (MAPK) pathway. E35 exposure evoked autophagic activity prior to apoptosis induction, and autophagy inhibition by 3-methyladenine (3-MA) dramatically increased E35-induced apoptosis in both AML cell lines and patient-derived AML cells. Nevertheless, study on AML xenograft model showed that the combination E35 with 3-MA exhibited much more inhibitory effects on leukemia cell growth in vivo. No obvious adverse reactions occurred in the xenograft animals administered E35 alone or its cotreatment with 3-MA. These findings suggest that E35 could exert anti-leukemia effects, and that the combination of E35 and autophagy inhibitor might prove a more highly efficient strategy for AML treatment.

【摘要】: 神经胶质瘤细胞主要依赖谷氨酸/胱氨酸转运体(glutamate/cystine antiporter, xc-)摄取胱氨酸合成谷胱甘肽(GSH),维持细胞的抗氧化能力。 本研究以神经胶质瘤C6细胞、原代培养的星形胶质细胞和常常被作为神经元模型的嗜铬细胞瘤PC-12细胞为研究对象,观察谷氨酸/胱氨酸转运体抑制剂—柳氮磺吡啶(SAS)对三种细胞存活率的影响,进一步探讨不同类型的氧化剂对SAS抑制细胞增殖作用的影响及其机制,通过分析谷氨酸/胱氨酸转运体在肿瘤形成中的作用,为神经胶质瘤的治疗提供理论基础。 本实验证明了相对于原代培养的星形胶质细胞和神经元,谷氨酸/胱氨酸转运体抑制剂SAS对C6细胞增殖的抑制作用较强,呈剂量依赖性,表明SAS对C6细胞增殖具有特异性的抑制作用。 其次,SAS分别与维生素K3(VK_3)或过氧化氢(H_2O_2)同时添加,通过以下机制抑制细胞增殖:(1)使xCT表达降低,内源性导致合成GSH的原料—胱氨酸缺乏; (2)通过使C6细胞内活性氧增多,外源性导致细胞内原有的GSH进一步消耗增多; (3)抑制GSH合成的限速酶—谷氨酸半胱氨酸连接酶(GCL)亚单位GCLC、GCLM的表达,内源性导致C6细胞内新的GSH合成受限,引起C6细胞内的GSH含量下降;

机译: 对谷氨酰胺剥夺具有抗性的白血病细胞表达谷氨酰胺合成酶蛋白 摘要 Objective: Low glutamine levels have been shown in tumor environments for several cancer subtypes. Therefore, it has been suggested that cancer cells rewire their metabolism to adopt low nutrient levels for survival and proliferation. Although glutamine is a non-essential amino acid and can be synthesized de novo, many cancer cells including malignant hematopoietic cells have been indicated to be addicted to glutamine. This study aimed to investigate the proliferation of leukemia cell lines in glutamine-deprived conditions. Materials and Methods: Cell proliferation of K562, NB-4, and HL-60 cells was determined by calculating cell numbers in normal vs. low glutamine media. Changes in mRNA expressions were investigated using qRT-PCR. The glutamine synthetase (GS)-encoding GLUL gene was knocked out (KO) in HL-60 cells using the CRISPR/Cas9 method and protein expression was evaluated with immunoblotting. Results: The proliferation of all cell lines was decreased in glutamine-deprived medium. GS protein expression was increased in glutamine-limited medium although the mRNA level did not change. Increased protein expression was confirmed with inhibition of new protein synthesis by treating cells with cycloheximide. To further investigate the role of GS protein, the GS-encoding GLUL gene was KO in HL-60 cells using the CRISPR/Cas9 method. GS KO cells proliferated less compared to control cells in glutamine-limited medium. Conclusion: Our results i

To explore this hypothesis, we combined CB-839, an inhibitor of glutaminase 1 (GLS1), the mitochondrial enzyme responsible for catalyzing conversion of therapy. The combination of cetuximab with CB-839 resulted in reduced cell viability and demonstrated synergism in several cell lines.

Abstract Acute myeloid leukemia (AML) is a blood cancer that is poorly responsive to conventional cytotoxic chemotherapy and a diagnosis of AML is usually fatal. More effective and better-tolerated therapies for AML are desperately needed. Activating mutations in FMS-like tyrosine kinase 3 (FLT3) are one of the most frequently observed genetic defects in AML. FLT3 inhibitors have shown impressive anti-leukemic activity in clinical trials; however, sustained remissions using these inhibitors as monotherapy have not been achieved. Our previous studies have implicated impaired glutamine metabolism in response to FLT3 inhibitors as a dominant factor causing AML cell death. In this study, we have employed metabolic flux analysis to examine the effects of FLT3 inhibition on glutamine utilization in FLT3-mutated AML cells using stable isotope tracers. We found that the FLT3 inhibitor AC220 inhibited glutamine flux into the antioxidant factor glutathione profoundly due to defective glutamine import. We also found that the glutaminase inhibitor CB-839 similarly impaired glutathione production by effectively blocking flux of glutamine into glutamate. Moreover, the combination of AC220 with CB-839 synergized to deplete glutathione, induce mitochondrial reactive oxygen species, and cause loss of viability through apoptotic cell death. In vivo, glutaminase inhibition with CB-839 facilitated leukemic cell elimination by AC220 and improved survival significantly in a patient-derived xenogra
