Cancers (Basel) 2023; 15:cancers15113063. [PMID: 37297025 DOI: 10.3390/cancers15113063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 05/26/2023] [Accepted: 06/01/2023] [Indexed: 06/12/2023] Open
Abstract
Three AML cell variants (M/A, M/A* from MOLM-13 and S/A from SKM-1) were established for resistance by the same protocol using 5-azacytidine (AZA) as a selection agent. These AZA-resistant variants differ in their responses to other cytosine nucleoside analogs, including 5-aza-2'-deoxycytidine (DAC), as well as in some molecular features. Differences in global DNA methylation, protein levels of DNA methyltransferases, and phosphorylation of histone H2AX were observed in response to AZA and DAC treatment in these cell variants. This could be due to changes in the expression of uridine-cytidine kinases 1 and 2 (UCK1 and UCK2) demonstrated in our cell variants. In the M/A variant that retained sensitivity to DAC, we detected a homozygous point mutation in UCK2 resulting in an amino acid substitution (L220R) that is likely responsible for AZA resistance. Cells administered AZA treatment can switch to de novo synthesis of pyrimidine nucleotides, which could be blocked by inhibition of dihydroorotate dehydrogenase by teriflunomide (TFN). This is shown by the synergistic effect of AZA and TFN in those variants that were cross-resistant to DAC and did not have a mutation in UCK2.

Abstract
Metabolic rewiring and cellular reprogramming are trademarks of neoplastic initiation and progression in acute myeloid leukemia (AML). Metabolic alteration in leukemic cells is often genotype specific, with associated changes in epigenetic and functional factors resulting in the downstream upregulation or facilitation of oncogenic pathways. Targeting abnormal or disease-sustaining metabolic activities in AML provides a wide range of therapeutic opportunities, ideally with enhanced therapeutic windows and robust clinical efficacy. This review highlights the dysregulation of amino acid, nucleotide, lipid, and carbohydrate metabolism in AML; explores the role of key vitamins and enzymes that regulate these processes; and provides an overview of metabolism-directed therapies currently in use or development.

Solute Carrier Family 29A1 Mediates In Vitro Resistance to Azacitidine in Acute Myeloid Leukemia Cell Lines. Int J Mol Sci 2023; 24:ijms24043553. [PMID: 36834962 PMCID: PMC9965596 DOI: 10.3390/ijms24043553] [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: 01/20/2023] [Revised: 02/03/2023] [Accepted: 02/07/2023] [Indexed: 02/12/2023] Open
Abstract
Azacitidine (AZA) is commonly used hypomethylating agent for higher risk myelodysplastic syndromes and acute myeloid leukemia (AML). Although some patients achieve remission, eventually most patients fail AZA therapy. Comprehensive analysis of intracellular uptake and retention (IUR) of carbon-labeled AZA (14C-AZA), gene expression, transporter pump activity with or without inhibitors, and cytotoxicity in naïve and resistant cell lines provided insight into the mechanism of AZA resistance. AML cell lines were exposed to increasing concentrations of AZA to create resistant clones. 14C-AZA IUR was significantly lower in MOLM-13- (1.65 ± 0.08 ng vs. 5.79 ± 0.18 ng; p < 0.0001) and SKM-1- (1.10 ± 0.08 vs. 5.08 ± 0.26 ng; p < 0.0001) resistant cells compared to respective parental cells. Importantly, 14C-AZA IUR progressively reduced with downregulation of SLC29A1 expression in MOLM-13- and SKM-1-resistant cells. Furthermore, nitrobenzyl mercaptopurine riboside, an SLC29A inhibitor, reduced 14C-AZA IUR in MOLM-13 (5.79 ± 0.18 vs. 2.07 ± 0.23, p < 0.0001) and SKM-1-naive cells (5.08 ± 2.59 vs. 1.39 ± 0.19, p = 0.0002) and reduced efficacy of AZA. As the expression of cellular efflux pumps such as ABCB1 and ABCG2 did not change in AZA-resistant cells, they are unlikely contribute to AZA resistance. Therefore, the current study provides a causal link between in vitro AZA resistance and downregulation of cellular influx transporter SLC29A1.

Abstract
Inosine monophosphate dehydrogenase (IMPDH) is a rate-limiting enzyme in de novo guanine nucleotide synthesis pathway. Although IMPDH inhibitors are widely used as effective immunosuppressants, their antitumor effects have not been proven in the clinical setting. Here, we found that acute myeloid leukemias (AMLs) with MLL-fusions are susceptible to IMPDH inhibitors in vitro. We also showed that alternate-day administration of IMPDH inhibitors suppressed the development of MLL-AF9-driven AML in vivo without having a devastating effect on immune function. Mechanistically, IMPDH inhibition induced overactivation of Toll-like receptor (TLR)-TRAF6-NF-κB signaling and upregulation of an adhesion molecule VCAM1, which contribute to the antileukemia effect of IMPDH inhibitors. Consequently, combined treatment with IMPDH inhibitors and the TLR1/2 agonist effectively inhibited the development of MLL-fusion AML. These findings provide a rational basis for clinical testing of IMPDH inhibitors against MLL-fusion AMLs and potentially other aggressive tumors with active TLR signaling.

Abstract
Neuroblastoma is a pediatric cancer responsible for approximately 15% of all childhood cancer deaths. Aberrant MYCN activation, as a result of genomic MYCN amplification, is a major driver of high-risk neuroblastoma, which has an overall survival rate of less than 50%, despite the best treatments currently available. Metabolic reprogramming is an integral part of the growth-promoting program driven by MYCN, which fuels cell growth and proliferation by increasing the uptake and catabolism of nutrients, biosynthesis of macromolecules, and production of energy. This reprogramming process also generates metabolic vulnerabilities that can be exploited for therapy. In this review, we present our current understanding of metabolic reprogramming in neuroblastoma, focusing on transcriptional regulation as a key mechanism in driving the reprogramming process. We also highlight some important areas that need to be explored for the successful development of metabolism-based therapy against high-risk neuroblastoma.

Abstract
Patients with myelodysplastic syndromes (MDS) who resist or fail to respond to hypomethylating agents (HMAs) show very poor outcomes and have no effective treatment strategies. Therefore, new therapeutic approaches are urgently needed for MDS patients harboring adverse prognostic factors. Repurposing disulfiram (DSF), an alcohol-abuse drug, with or without Copper (Cu) has attracted considerable attentions as a candidate anti-tumor therapy in diverse malignancies. However, the effect of DSF in the presence or absence of Cu on MDS has not been reported yet. In this study, we found that monotherapy with DSF showed mild cytotoxic effects on MDS preclinical models. However, the anti-tumor activity of DSF was significantly enhanced in the presence of Cu in MDS in vitro and in vivo with minimal safety profiles. DSF/Cu combination blocked MDS cell cycle progression at the G0/G1 phase, accompanied by reduction of the S phase. Accordingly, co-treatment with DSF and Cu downregulated the expression of Cyclin D1 and Cyclin A2, whereas this combination upregulated the level of P21 and P27. Mechanistically, the anti-MDS effectiveness of DSF/Cu was potentially associated with activation of the ER stress-related Bip pathway and inactivation of the Akt pathway. In addition, inhibition of autophagy process also contributed to the cytotoxicity of DSF/Cu in MDS cells. In conclusion, these findings provide impressive evidence that the DSF/Cu complex shows potent anti-tumor efficacies on MDS preclinical models, representing a potential alternative therapy for MDS patients and warranting further investigation in clinical contexts.

Abstract
Acute myeloid leukemia (AML) is a complex, heterogenous hematological malignancy caused by mutations in myeloid differentiation and proliferation. Response to therapy and long-term outcomes vary widely based on chromosomal and molecular aberrations. Many platforms have been used to characterize and stratify AML. Metabolomics, the global profiling of small molecules in a biological sample, has emerged in the last decade as an important tool for studying the metabolic dependency of cancer cells. Metabolic reprogramming is not only an important manifestation of AML but clinically relevant for diagnosis, risk stratification and targeted drug development. In this review, we discuss notable metabolic studies of the last decade and their application to novel therapies.

Abstract
FF-10501-01 potently inhibits inosine-5-monophosphate dehydrogenase (IMPDH), inducing anti-proliferative and pro-apoptotic effects in acute myeloid leukemia (AML) human cell lines resistant to hypomethylating agents. In this Phase 1/2a study, Phase 1 enrolled 38 patients with relapsed/refractory AML (n = 28) or myelodysplastic syndromes (MDS/CMML, n = 10) to receive FF-10501 oral doses 50-500 mg/m2 BID for 14 or 21 days out of each 28-day cycle. Fifteen additional patients with HMA-resistant MDS/CMML (Phase 2a) were treated at 400 mg/m2 BID for 21 days. Most Phase 1 adverse events were disease-related and low-grade. 3 of 19 (16%) evaluable AML patients achieved partial remission (31, 7, and 5 months). 2 of 20 (10%) evaluable MDS/CMML patients (Phase 1 and 2a) attained marrow complete remission, one continuing treatment for 17 months. While FF-10501-01 demonstrated clinical activity and target inhibition in heavily pretreated patients with AML and MDS/CMML, increased mucositis events led to Phase 2a closure (ClinTrials.gov#NCT02193958).

Abstract
The purine nucleotides ATP and GTP are essential precursors to DNA and RNA synthesis and fundamental for energy metabolism. Although de novo purine nucleotide biosynthesis is increased in highly proliferating cells, such as malignant tumors, it is not clear if this is merely a secondary manifestation of increased cell proliferation. Suggestive of a direct causative effect includes evidence that, in some cancer types, the rate-limiting enzyme in de novo GTP biosynthesis, inosine monophosphate dehydrogenase (IMPDH), is upregulated and that the IMPDH inhibitor, mycophenolic acid (MPA), possesses anti-tumor activity. However, historically, enthusiasm for employing IMPDH inhibitors in cancer treatment has been mitigated by their adverse effects at high treatment doses and variable response. Recent advances in our understanding of the mechanistic role of IMPDH in tumorigenesis and cancer progression, as well as the development of IMPDH inhibitors with selective actions on GTP synthesis, have prompted a reappraisal of targeting this enzyme for anti-cancer treatment. In this review, we summarize the history of IMPDH inhibitors, the development of new inhibitors as anti-cancer drugs, and future directions and strategies to overcome existing challenges.

Abstract
FF-10501 is a novel inhibitor of inosine monophosphate dehydrogenase (IMPDH). Clinical trials of FF-10501 for myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) are currently being conducted in the United States. Although it has been shown that FF-10501 induces apoptosis in hematological malignant cells, the intracellular mechanisms of this effect have not been characterized. We conducted an in vitro study to elucidate the mechanisms of FF-10501-induced cell death using 12 hematological malignant cell lines derived from myeloid and lymphoid malignancies. FF-10501 suppressed the growth of each cell line in a dose-dependent manner. However, the clinically relevant dose (40 μM) of FF-10501 induced cell death in three cell lines (MOLM-13, OCI-AML3, and MOLT-3). Investigation of the cell death mechanism suggested that FF-10501 induces both apoptotic and necrotic cell death. FF-10501-induced apoptosis was mediated by caspase-8 activation followed by activation of the mitochondrial pathway in MOLM-13 and MOLT-3 cells. FF-10501 induced necrotic cell death via endoplasmic reticulum stress in OCI-AML3 cells. The present study is the first to identify intracellular pathways involved in FF-10501-induced cell death.

The high NRF2 expression confers chemotherapy resistance partly through up-regulated DUSP1 in myelodysplastic syndromes. Haematologica 2018; 104:485-496. [PMID: 30262569 PMCID: PMC6395322 DOI: 10.3324/haematol.2018.197749] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2018] [Accepted: 09/26/2018] [Indexed: 11/15/2022] Open
Abstract
Although cytarabine has been widely considered as one of the chemotherapy drugs for high-risk myelodysplastic syndromes (MDS), the overall response rate is only approximately 20-30%. Nuclear factor erythroid 2-related factor 2 (NRF2, also called NFE2L2) has been shown to play a pivotal role in preventing cancer cells from being affected by chemotherapy. However, it is not yet known whether NRF2 can be used as a prognostic biomarker in MDS, or whether elevated NRF2 levels are associated with cytarabine resistance. Here, we found that NRF2 expression levels in bone marrow from high-risk patients exceeded that of low-risk MDS patients. Importantly, high NRF2 levels are correlated with inferior outcomes in MDS patients (n=137). Downregulation of NRF2 by the inhibitor Luteolin, or lentiviral shRNA knockdown, enhanced the chemotherapeutic efficacy of cytarabine, while MDS cells treated by NRF2 agonist Sulforaphane showed increased resistance to cytarabine. More importantly, pharmacological inhibition of NRF2 could sensitize primary high-risk MDS cells to cytarabine treatment. Mechanistically, downregulation of dual specificity protein phosphatase 1, an NRF2 direct target gene, could abrogate cytarabine resistance in NRF2 elevated MDS cells. Silencing NRF2 or dual specificity protein phosphatase 1 also significantly sensitized cytarabine treatment and inhibited tumors in MDS cells transplanted mouse models in vivo. Our study suggests that targeting NRF2 in combination with conventional chemotherapy could pave the way for future therapy for high-risk MDS.

Abstract
Background Nucleoside triphosphates participate in fundamental cellular processes as building blocks of DNA and RNA, energy carriers, and cofactors in enzymatic reactions, and their balance is tightly regulated. Here, we established a simultaneous and absolute quantification method for eight nucleoside triphosphates using liquid chromatography–triple quadrupole tandem mass spectrometry and hydrophilic interaction chromatography. Our method was successfully applied to the extract of human acute myeloid leukemia Molm-13 cells. Results Levels of ribonucleoside triphosphates (2.07 × 108–2.29 × 109 molecules/cell) in Molm-13 cells were two orders of magnitude higher than those of deoxyribonucleoside triphosphates (1.72 × 106–1.40 × 107 molecules/cell). Exposure of Molm-13 cells for 24 h to thymidine, a nucleotide imbalance inducer, increased the levels of cellular dTTP, dGTP, and dATP and decreased only dCTP, resulting in significant inhibition of cell proliferation. Conclusion Our quantification method for nucleoside triphosphates revealed the quantitative relationship between the arrest of cell proliferation and the imbalance of nucleoside triphosphates in thymidine-treated Molm-13 cells. Owing to the short run time (15 min/run), broad adaptability, and throughput performance, we believe that our method is a powerful tool for not only genetic and molecular biology research but also for studying the mechanism of genotoxic compounds and anti-cancer or anti-virus drugs, drug screening, clinical studies, and other fields.

Abstract
One of the major symptoms of myelodysplastic syndromes (MDS) is severe cytopenia. Despite cytokine therapies, such as erythropoiesis-stimulating agents, many patients still require blood transfusions, and the development of new therapeutic approaches is needed. In this work, we studied the effects of the inosine-5'-monophosphate (IMP) dehydrogenase (IMPDH) inhibitor FF-10501 on erythropoiesis of human hematopoietic cells. Differentiation of K562 chronic myeloid leukemia cells to an erythroid lineage was promoted by FF-10501 in a dose-dependent manner. Interestingly, we found that metabolic conversion of IMP to hypoxanthine leads to elevation of reactive oxygen species (ROS). The differentiative effects of FF-10501 were abolished by the ROS scavenger dimethylthiourea or the p38 MAPK inhibitor SB203580. Furthermore, FF-10501 promoted erythropoiesis from CD34+ hematopoietic stem/progenitor cells, accompanied with ROS accumulation, while high-dose FF-10501 mainly showed cytotoxic effects. These findings denote the potential of IMPDH inhibition therapy with FF-10501 in amelioration of anemia in MDS patients.

Preclinical activity of FF-10501-01, a novel inosine-5'-monophosphate dehydrogenase inhibitor, in acute myeloid leukemia. Leuk Res 2017; 59:85-92.

Abstract
BACKGROUND FF-10501-01 is a selective inosine monophosphate dehydrogenase (IMPDH) inhibitor that has shown activity in cancer cell lines. We studied whether FF-10501-01 is effective in targeting a variety of hypomethylating agent (HMA)-sensitive and -resistant acute myelogenous leukemia (AML) cell lines. METHODS We treated multiple cell lines (including HMA-resistant cells) with FF-10501-01 and analyzed proliferation, apoptosis, and cell cycle status. We also assessed HMA-FF-10501-01 combinations and the ability of extracellular guanosine to rescue cell proliferation in FF-10501-01-treated cells. We performed high-performance liquid chromatography (HPLC) to study guanine nucleotide levels in treated and untreated cells. Finally, we studied the effects of FF-10501-01 in fresh peripheral blood cells taken from AML patients. RESULTS FF-10501-01 showed a strong dose-dependent effect on proliferation and induced apoptosis at approximately 30μM. The effects of FF-10501-01 treatment on cell cycle status were variable, with no statistically significant trends. Guanosine rescued proliferation in FF-10501-01-treated cells, and HPLC results showed significant decreases in phosphorylated guanosine levels in MOLM13 cells. FF-10501-01 effectively reduced proliferation at concentrations of 300μM and above in 3 primary AML samples. CONCLUSIONS FF-10501-01 effectively induces AML cell death and reduces AML peripheral blood cell proliferation by targeting guanine nucleotide biosynthesis regardless of HMA resistance status.

Lack of cross-resistance to FF-10501, an inhibitor of inosine-5'-monophosphate dehydrogenase, in azacitidine-resistant cell lines selected from SKM-1 and MOLM-13 leukemia cell lines. Pharmacol Res Perspect 2016; 4:e00206.

Abstract
Resistance to azacitidine is a major issue in the treatments of myelodysplastic syndrome and acute myeloid leukemia, and previous studies suggest that changes in drug metabolism are involved in the resistance. Therefore, drugs with mechanisms resistant or alternative to such metabolic changes have been desired for the treatment of resistant disease. We generated azacitidine‐resistant cells derived from SKM‐1 and MOLM‐13 leukemia cell lines in vitro, analyzed the mechanisms, and examined the impact on the efficacy of other antimetabolic drugs. It appeared that the cell growth‐inhibitory effect of azacitidine, expression levels of uridine–cytidine kinase 2, and the concentrations of azacitidine triphosphate were remarkably decreased in the resistant cells compared with those in parent cells. These results were consistent with previous observations that azacitidine resistance is derived from metabolic changes. Cross‐resistance of greater than 10‐fold (shift in IC50 value) was observed in azacitidine‐resistant cells for decitabine and for cytarabine, but not for gemcitabine or the inosine‐5′‐monophosphate dehydrogenase (IMPDH) inhibitors FF‐10501 and mycophenolate mofetil (cross‐resistance to 5‐fluorouracil was cell line dependent). The IMPDH inhibitors maintained their cell growth‐inhibitory activities in the azacitidine‐resistant cell lines, in which the levels of adenine phosphoribosyltransferase (which converts FF‐10501 to its active form, FF‐10501 ribosylmonophosphate [FF‐10501RMP]), FF‐10501RMP, and the target enzyme, IMPDH, were equivalent to those in the parent cell lines. These results suggest that an IMPDH inhibitor such as FF‐10501 could be an alternative therapeutic treatment for leukemia patients with acquired resistance to azacitidine.
