Targeting Glutaminolysis Shows Efficacy in Both Prednisolone-Sensitive and in Metabolically Rewired Prednisolone-Resistant B-Cell Childhood Acute Lymphoblastic Leukaemia Cells. Int J Mol Sci 2023; 24:ijms24043378. [PMID: 36834787 PMCID: PMC9965631 DOI: 10.3390/ijms24043378] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 01/23/2023] [Accepted: 01/26/2023] [Indexed: 02/11/2023] Open
Abstract
The prognosis for patients with relapsed childhood acute lymphoblastic leukaemia (cALL) remains poor. The main reason for treatment failure is drug resistance, most commonly to glucocorticoids (GCs). The molecular differences between prednisolone-sensitive and -resistant lymphoblasts are not well-studied, thereby precluding the development of novel and targeted therapies. Therefore, the aim of this work was to elucidate at least some aspects of the molecular differences between matched pairs of GC-sensitive and -resistant cell lines. To address this, we carried out an integrated transcriptomic and metabolomic analysis, which revealed that lack of response to prednisolone may be underpinned by alterations in oxidative phosphorylation, glycolysis, amino acid, pyruvate and nucleotide biosynthesis, as well as activation of mTORC1 and MYC signalling, which are also known to control cell metabolism. In an attempt to explore the potential therapeutic effect of inhibiting one of the hits from our analysis, we targeted the glutamine-glutamate-α-ketoglutarate axis by three different strategies, all of which impaired mitochondrial respiration and ATP production and induced apoptosis. Thereby, we report that prednisolone resistance may be accompanied by considerable rewiring of transcriptional and biosynthesis programs. Among other druggable targets that were identified in this study, inhibition of glutamine metabolism presents a potential therapeutic approach in GC-sensitive, but more importantly, in GC-resistant cALL cells. Lastly, these findings may be clinically relevant in the context of relapse-in publicly available datasets, we found gene expression patterns suggesting that in vivo drug resistance is characterised by similar metabolic dysregulation to what we found in our in vitro model.

Downregulation of Glutamine Synthetase, not glutaminolysis, is responsible for glutamine addiction in Notch1-driven acute lymphoblastic leukemia. Mol Oncol 2021; 15:1412-1431. [PMID: 33314742 PMCID: PMC8096784 DOI: 10.1002/1878-0261.12877] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Revised: 10/21/2020] [Accepted: 12/09/2020] [Indexed: 01/03/2023] Open
Abstract
The cellular receptor Notch1 is a central regulator of T-cell development, and as a consequence, Notch1 pathway appears upregulated in > 65% of the cases of T-cell acute lymphoblastic leukemia (T-ALL). However, strategies targeting Notch1 signaling render only modest results in the clinic due to treatment resistance and severe side effects. While many investigations reported the different aspects of tumor cell growth and leukemia progression controlled by Notch1, less is known regarding the modifications of cellular metabolism induced by Notch1 upregulation in T-ALL. Previously, glutaminolysis inhibition has been proposed to synergize with anti-Notch therapies in T-ALL models. In this work, we report that Notch1 upregulation in T-ALL induced a change in the metabolism of the important amino acid glutamine, preventing glutamine synthesis through the downregulation of glutamine synthetase (GS). Downregulation of GS was responsible for glutamine addiction in Notch1-driven T-ALL both in vitro and in vivo. Our results also confirmed an increase in glutaminolysis mediated by Notch1. Increased glutaminolysis resulted in the activation of the mammalian target of rapamycin complex 1 (mTORC1) pathway, a central controller of cell growth. However, glutaminolysis did not play any role in Notch1-induced glutamine addiction. Finally, the combined treatment targeting mTORC1 and limiting glutamine availability had a synergistic effect to induce apoptosis and to prevent Notch1-driven leukemia progression. Our results placed glutamine limitation and mTORC1 inhibition as a potential therapy against Notch1-driven leukemia.

Abstract
We compared the ability of human leukemia cell lines of various origins to grow in glutamine-deficient media. The growth of B lymphoblastoid cell lines, including promyelocytic HL-60, is highly dependent on glutamine, whereas T-cell lines are able to proliferate in glutamine-free media. Such glutamine dependency has a good inverse correlation with the activity of glutamine synthetase. Moreover, glutamine synthetase can be induced in glutamine-deficient media, especially in glutamine-independent cells. In HL-60 cells, glutamine deprivation results in the decrease of both ATP and dATP levels. The addition of adenine to the culture medium abolishes these changes without restoring cell growth, indicating that the effects of glutamine deprivation on cell growth cannot be fully explained by the perturbation of adenine nucleotide pools.

Abstract
The biochemistry of human B lymphocyte differentiation to plasma cells is incompletely understood. L-glutamine appears to be required for both lymphoblastic transformation and plasma cell formation in pokeweed-mitogen-stimulated human peripheral blood mononuclear cell cultures. Cells cultured with pokeweed mitogen in glutamine-deficient RPMI-1640 with 10% heat-inactivated and dialyzed fetal bovine serum were unable to incorporate 3H-thymidine or undergo morphologic lymphoblastic transformation assessed at 72 hours. However, 3H-thymidine incorporation could be maximally restored with as little as 0.08 mM L-glutamine or by using nondialyzed heat-inactivated fetal bovine serum, containing approximately. 1 mM L-glutamine. In subsequent cultures, using glutamine-deficient RPMI-1640 with 10% nondialyzed heat-inactivated fetal bovine serum, lymphoblastic transformation was equivalent with or without additional L-glutamine supplementation. However, only cultures with 2 mM L-glutamine supplementation underwent plasma cell differentiation as assessed by cytoplasmic staining with fluorescein-conjugated anti-immunoglobulin. When the kinetics of cellular immunoglobulin synthesis and secretion were analyzed by 3H- leucine incorporation into immunoglobulin, synthesis was 2-5 fold greater, and secretion 3-10-fold greater in cell cultures with 2 mM L-glutamine supplementation. By electron microscopy, only the glutamine-supplemented cells showed development of rough endoplasmic reticulum consistent with active immunoglobulin production. L-glutamine supplementation had no apparent effect on cell recovery, viability, % B cells, % T cells, % monocytes, or % helper and suppressor T cells. Thus, L-glutamine is essential for both lymphoblastic transformation and plasma cell differentiation. Future investigation of the selective nutritional requirements of cultured cells should yield further insights into the biochemical control of immune cell differentiation and function.
