NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2024; 397:3565-3584. [PMID: 38015258 DOI: 10.1007/s00210-023-02865-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 11/20/2023] [Indexed: 11/29/2023]
Abstract
Cytarabine, an antimetabolite antineoplastic agent, has been utilized to treat various cancers. However, because of its short half-life, low stability, and limited bioavailability, achieving an optimal plasma concentration requires continuous intravenous administration, which can lead to toxicity in normal cells and tissues. Addressing these limitations is crucial to optimize the therapeutic efficacy of cytarabine while minimizing its adverse effects. The use of novel drug delivery systems, such as polymer-based nanocarriers have emerged as promising vehicles for targeted drug delivery due to their unique properties, including high stability, biocompatibility, and tunable release kinetics. In this review, we examine the application of various polymer-based nanocarriers, including polymeric nanoparticles, polymeric micelles, dendrimers, polymer-drug conjugates, and nano-hydrogels, for the delivery of cytarabine. The article highlights the limitations of conventional cytarabine administration which often lead to suboptimal therapeutic outcomes and systemic toxicity. The rationale for using polymer-based nanocarriers is discussed, highlighting their ability to overcome challenges by providing controlled drug release, improved stability, and enhanced targeting capabilities. In summary, this review offers a valuable resource for drug delivery scientists by providing insights into the design principles, formulation strategies, and potential applications of polymer-based nanocarriers that can enhance the therapeutic efficacy of cytarabine.

CALCRL knockdown suppresses cancer stemness and chemoresistance in acute myeloid leukemia with FLT3-ITD and DNM3TA-R882 double mutations. Drug Dev Res 2024; 85:e22137. [PMID: 38349260 DOI: 10.1002/ddr.22137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 11/09/2023] [Accepted: 11/21/2023] [Indexed: 02/15/2024]
Abstract
Acute myeloid leukemia (AML) patients with FLT3 internal tandem duplication (FLT3-ITD) and DNA methyltransferase 3A (DNMT3A) R882 double mutations had a worse prognosis compared with AML with FLT3-ITD or DNMT3A R882 single mutation. This study was designed to explore the specific role of Calcitonin Receptor Like (CALCRL) in AML with FLT3-ITD and DNMT3A R882 double mutations. MOLM13 cells were transduced with CRISPR knockout sgRNA constructs to establish the FTL3-ITD and DNMT3A-R882 double-mutated AML cell model. Quantitative real-time PCR and Western blot assay were carried out to examine corresponding gene and protein expression. Methylation of CALCRL promoter was measured by methylation-specific PCR (MSP). Cell viability, colony formation, flow cytometry, and sphere formation assays were conducted to determine cell proliferation, apoptosis, and stemness. MOLM13 cells were exposed to stepwise increasing concentrations of cytarabine (Ara-C) to generate MOLM13/Ara-C cells. An in vivo AML animal model was established, and the tumor volume and weight were recorded. TUNEL assay was adopted to examine cell apoptosis in tumor tissues. DNMT3A-R882 mutation upregulated the expression of CALCRL while downregulated the DNA methylation level of CALCRL in MOLM13 cells. CALCRL knockdown greatly inhibited cell proliferation, promoted apoptosis and repressed cell stemness, accompanied with the downregulated Oct4, SOX2, and Nanog in DNMT3A-R882-mutated MOLM13 cells and MOLM13/Ara-C cells. Furthermore, CALCRL knockdown restricted tumor growth and the chemoresistance of AML in vivo, as well as inducing cell apoptosis in tumor tissues. Together, these data reveal that CALCRL is a vital regulator of leukemia cell survival and resistance to chemotherapy, suggesting CALCRL as a promising therapeutic target for the treatment of FTL3-ITD and DNMT3A-R882 double-mutated AML.

Abstract
Nanomedicine has garnered significant attention due to the advantages it offers in the treatment of cancer-related disorders, some of the deadliest diseases affecting human lives. Conventional medication formulations often encounter issues of instability or insolubility in biological environments, resulting in low bioavailability. Nanocarriers play a crucial role in transporting and safeguarding drugs at specific sites of action, enabling gradual release under particular conditions. This study focuses on methotrexate (MTx) and cytarabine (Cyt), essential antitumoral drugs, loaded into PEGylated squalene micellar structures to enhance therapeutic effectiveness and minimize drawbacks. The micelles were prepared using ultrasound-assisted methods in both water and phosphate buffer saline solutions. Evaluation of drug-loaded micelles encompassed parameters such as particle size, colloidal stability, surface charge, morphology, encapsulation efficiency, drug loading capacity, and in vitro release profiles under simulated physiological and tumoral conditions. In vitro cell inhibition studies conducted on MCF-7 and HeLa cell lines demonstrated higher antitumoral activity for the drug-encapsulated micelles compared to free drugs. The encapsulation effectively addressed the burst effect, providing sustained release for at least 48 h while enhancing the drug's protection under physiological conditions.

Abstract
Chemoresistance often complicates the management of cancer, as noted in the instance of acute myeloid leukemia (AML). Mitochondrial function is considered important for the viability of AML blasts and appears to also modulate chemoresistance. As mitochondrial metabolism is aberrant in AML, any distinct pathways could be directly targeted to impact both cell viability and chemoresistance. Therefore, identifying and targeting those precise rogue elements of mitochondrial metabolism could be a valid therapeutic strategy in leukemia. Here, we review the evidence for abnormalities in mitochondria metabolic processes in AML cells, that likely impact chemoresistance. We further address several therapeutic approaches targeting isocitrate dehydrogenase 2 (IDH2), CD39, nicotinamide phosphoribosyl transferase (NAMPT), electron transport chain (ETC) complex in AML and also consider the roles of mesenchymal stromal cells. We propose the term "mitotherapy" to collectively refer to such regimens that attempt to override mitochondria-mediated metabolic reprogramming, as used by cancer cells. Mounting evidence suggests that mitotherapy could provide a complementary strategy to overcome chemoresistance in liquid cancers, as well as in solid tumors.

Abstract
Leukemic-stem-cell-specific targeting may improve the survival of patients with acute myeloid leukemia (AML) by avoiding the ablative effects of standard regimens on normal hematopoiesis. Herein, we perform an unbiased screening of compounds targeting cell surface proteins and identify clinically used DPP4 inhibitors as strong suppressors of AML development in both murine AML models and primary human AML cells xenograft model. We find in retrovirus-induced AML mouse models that DPP4-deficient AML cell-transplanted mice exhibit delay and reversal of AML development, whereas deletion of DPP4 has no significant effect on normal hematopoiesis. DPP4 activates and sustains survival of AML stem cells that are critical for AML development in both human and animal models via binding with Src kinase and activation of nuclear factor κB (NF-κB) signaling. Thus, inhibition of DPP4 is a potential therapeutic strategy against AML development through suppression of survival and stemness of AML cells.

Abstract
INTRODUCTION Acute myeloid leukemia (AML) is a heterogeneous disease characterized by many cytogenetic and molecular alterations. Due to better knowledge of the molecular basis of AML, many targeted therapies have been introduced and registered, e.g. FMS-like tyrosine kinase 3 inhibitors, isocitrate dehydrogenase 1/2 mutation inhibitors, and Bcl-2 inhibitor. Despite that, the cure for AML remains an unmet clinical need in most patients. AREAS COVERED The review aims to present new, not yet registered drugs for AML. We searched the English literature for articles concerning AML, targeted drugs, menin inhibitors, DOT1L, BET, IDH inhibitors, FLT3, hedgehog inhibitors, Polo-like kinase inhibitors, RNA splicing, and immune therapies via PubMed. Publications from January 2000 to August 2022 were scrutinized. Additional relevant publications were obtained by reviewing the references from the chosen articles and Google search. Conference proceedings from the previous 5 years of The American Society of Hematology, the European Hematology Association, and the American Society of Clinical Oncology were searched manually. Additional relevant publications were obtained by reviewing the references. EXPERT OPINION For several years, the therapeutic approach in AML has become more individualized. Novel groups of drugs give hope for greater curability. High response rates have agents that restore the activity of the p53 protein. In addition, agents that work independently of a particular mutation seem promising for AML without any known mutation.

Abstract
Drug resistance and relapse lead to high mortality in acute myeloid leukemia, and studies have shown that CXCR4 overexpression is highly correlated with poor prognosis and drug resistance in leukemia cells. Isolation and detection of AML cells with CXCR4 overexpression will be crucial to the treatment of AML. In this paper, magnetic nanoparticles were firstly prepared successfully by high-temperature thermal decomposition method, and then characterized by TEM, VSM and DLS. Subsequently CXCR4-targeted magnetic fluorescent nanoprobes conjugated with antibody 12G5 were constructed by stepwise coupling. In cell experiments, the obtained probes demonstrated excellent targeting efficacy to CXCR4 overexpressed AML cells HL-60. In addition, HL-60 cells labelled with the magnetic probes can be magnetic isolated successfully in one microfluidics chip, with efficiency of 82.92 ± 7.03%. Overall, this method utilizes the superiority of superparamagnetic nanomaterials and microfluidic technology to achieve the enrichment and capture of drug-resistant cells in a microfluidic chip, providing a new idea for the isolation and detective of drug-resistant acute myeloid leukemia cells.

Abstract
Chalcones and their derivatives have been described as promising compounds with antiproliferative activity against leukemic cells. This study aimed to investigate the cytotoxic effect of three synthetic chalcones derived from 1-naphthylacetophenone (F07, F09, and F10) in acute leukemia cell lines (K562 and Jurkat) and examine the mechanisms of cell death induced by these compounds. The three compounds were cytotoxic to K562 and Jurkat cells, with IC50 values ranging from 1.03 to 31.66 µM. Chalcones induced intrinsic and extrinsic apoptosis, resulting in activation of caspase-3 and DNA fragmentation. F07, F09, and F10 were not cytotoxic to human peripheral blood mononuclear cells, did not produce any significant hemolytic activity, and did not affect platelet aggregation after ADP stimulation. These results, combined with calculations of molecular properties, suggest that chalcones F07, F09, and F10 are promising molecules for the development of novel antileukemic drugs.

Abstract
Aims Acute myeloid leukemia (AML) is an aggressive hematologic neoplasm, in which relapse due to drug resistance is the main cause for treatment failure and the disease progression. In this study, we aimed to investigate the molecular mechanism of KDM4C-dependent MALAT1/miR-328-3p/CCND2 axis in cytarabine (Ara-C) resistance in the context of AML. Methods Bioinformatics analysis was performed to predict the targeting relationships among KDM4C, MALAT1, miR-328-3p, and CCND2 in AML, which were validated with chromatin immunoprecipitation and dual-luciferase reporter assay. Methylation-specific polymerase chain reaction was conducted to detect the methylation of MALAT1 promoter. After conducting gain- and loss-of-function assays, we investigated the effect of KDM4C on cell Ara-C resistance. A NOD/SCID mouse model was established to further investigate the roles of KDM4C/MALAT1/miR-328-3p/CCND2 in Ara-C resistant AML cells. Results KDM4C expression was upregulated in AML. KDM4C upregulation promoted the demethylation in the promoter region of MALAT1 to increase its expression, MALAT1 targeted and inhibited miR-328-3p expression, enhancing the Ara-C resistance of HL-60/A. miR-328-3p targeted and suppressed the expression of CCND2 in HL-60/A to inhibit the Ara-C resistance. Mechanistically, KDM4C regulated miR-328-3p/CCND2 through MALAT1, resulting in Ara-C resistance in AML. Findings in an in vivo xenograft NOD/SCID mouse model further confirmed the contribution of KDM4C/MALAT1/miR-328-3p/CCND2 in the Ara-C resistant AML. Conclusion Our study demonstrated that KDM4C may up-regulate MALAT1 expression, which decreases the expression of miR-328-3p. The downregulation of miR-328-3p increased the level of CCND2, which induced the Ara-C resistance in AML.

Abstract
PURPOSE Mortality due to acute myeloid leukemia (AML) remains high, and the management of relapsed or refractory AML continues to be therapeutically challenging. The reapproval of Mylotarg, an anti-CD33-calicheamicin antibody-drug conjugate (ADC), has provided a proof of concept for an ADC-based therapeutic for AML. Several other ADCs have since entered clinical development of AML, but have met with limited success. We sought to develop a next-generation ADC for AML with a wide therapeutic index (TI) that overcomes the shortcomings of previous generations of ADCs. EXPERIMENTAL DESIGN We compared the TI of our novel CD33-targeted ADC platform with other currently available CD33-targeted ADCs in preclinical models of AML. Next, using this next-generation ADC platform, we performed a head-to-head comparison of two attractive AML antigens, CD33 and CD123. RESULTS Our novel ADC platform offered improved safety and TI when compared with certain currently available ADC platforms in preclinical models of AML. Differentiation between the CD33- and CD123-targeted ADCs was observed in safety studies conducted in cynomolgus monkeys. The CD33-targeted ADC produced severe hematologic toxicity, whereas minimal hematologic toxicity was observed with the CD123-targeted ADC at the same doses and exposures. The improved toxicity profile of an ADC targeting CD123 over CD33 was consistent with the more restricted expression of CD123 in normal tissues. CONCLUSIONS We optimized all components of ADC design (i.e., leukemia antigen, antibody, and linker-payload) to develop an ADC that has the potential to translate into an effective new therapy against AML.

Wang N, Feng Y, Xie J, Han H, Dong Q, Wang W. Long Non-Coding RNA ZNF667-AS1 Knockdown Curbs Liver Metastasis in Acute Myeloid Leukemia by Regulating the microRNA-206/AKAP13 Axis. Cancer Manag Res 2020; 12:13285-13300. [PMID: 33380835 PMCID: PMC7767707 DOI: 10.2147/cmar.s269258] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Accepted: 11/25/2020] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Zinc finger protein 667-antisense RNA 1 (ZNF667-AS1), a long non-coding RNA (lncRNA), plays important parts in tumorigenesis and development of esophageal squamous cell carcinoma, but its function in acute myeloid leukemia (AML) is unknown. Our goal here was to probe the functional mechanism of ZNF667-AS1 in AML by mediating microRNA-206 (miR-206)/A-kinase anchoring protein 13 (AKAP13) axis. MATERIALS AND METHODS The bone marrow samples from AML patients and controls were selected for microarray analysis to select significantly upregulated lncRNAs. Next, effects of ZNF667-AS1 on cell aggressiveness of AML were assessed after delivery of cells with siRNA against ZNF667-AS1. Subcellular fractionation location assay and FISH experiments were used to determine ZNF667-AS1 localization in cells. Dual-luciferase experiments detect the targeting relationships among ZNF667-AS1, miR-206 and AKAP13. Finally, tumor growth and metastasis were evaluated in vivo to determine the relevance of ZNF667-AS1/miR-206/AKAP13 axis. RESULTS The expression of ZNF667-AS1 was upregulated in AML patients, which predicted poor prognosis. Downregulation of ZNF667-AS1 reduced cell proliferation, invasion, tumorigenesis and metastasis. miR-206 inhibitor reversed the repressive role of ZNF667-AS1 knockdown in cell proliferation, invasion and tumorigenesis, while AKAP13 silencing flattened the stimulative role of miR-206 inhibitor in AML malignant aggressiveness. Mechanistically, we demonstrated that ZNF667-AS1 functioned as a molecular sponge for miR-206. In addition, we observed that Wnt/β-catenin pathway was suppressed by ZNF667-AS1 knockdown. CONCLUSION ZNF667-AS1 potentiated AML progression by targeting the miR-206/AKAP13 axis. This indicates ZNF667-AS 1 inhibition may act as a prospective therapeutic option for the treatment of AML.

Abstract
BACKGROUND Excessive generation of reactive oxygen species (ROS) in the presence of a defective antioxidant system can induce cellular damage and disrupt normal physiological functions. Several studies have revealed the unfavorable role of ROS in promoting the growth, proliferation, migration, and survival of leukemia cells. In this review study, we summarize the mechanisms of ROS production and its role in leukemogenesis, counteractive effects of antioxidants, and implicate the current ROS-dependent anticancer therapies in acute myeloid leukemia. BODY: The dysregulation of the redox system is known to play a significant role in the pathogenesis of leukemia. Leukemia cells generate high levels of ROS, which further increases the levels through extra pathways, including mitochondrial deoxyribonucleic mutation, leukemic oncogene activation, increased nicotinamide adenine phosphate hydrogen (NADPH), and cytochrome P450 activities. Aforementioned pathways once activated have shown to promote genomic instability, induce drug resistance to leukemia medical therapy, disease relapse and reduce survival period. The current standard of treatment with chemotherapy employs the pro-oxidant approach to induce apoptosis and promote tumor regression. However, this approach retains several deleterious effects on the subject resulting in degradation of the quality of life. Nevertheless, the addition of an antioxidant as an adjuvant drug to chemotherapy alleviates treatment-related toxicity, increases chemotherapeutic efficacy, and improves survival rates of a patient. CONCLUSION Acute myeloid leukemia remains a daunting challenge to clinicians. The desire to achieve the maximum benefit of chemotherapy but also improve patient outcomes is investigated. ROS generated through several pathways promotes leukemogenesis, drug resistance, and disease relapse. Chemotherapy, the mainstay of treatment, further upregulates ROS levels. Therefore, the addition of an antioxidant to leukemia medical therapy alleviates toxicity and improves patient outcomes.

Abstract
Targeting autophagy holds promise to enhance chemosensitivity in acute myeloid leukemia (AML). MicroRNA-143 (miR-143) has been found to suppress autophagy, however, it is not clear whether miR-143 augments cytarabine cytotoxicity in AML. Here, we report that cytarabine treatment reduces miR-143 expression in AML cell lines and primary AML cells. Moreover, ectopic expression of miR-143 further decreases cell viability in cytarabine-treated AML cells. By contrast, miR-143 knockdown inhibits cytarabine-induced cytotoxicity, together indicating a role of miR-143 in enhancing cytarabine sensitivity in AML. Subsequently, we show that miR-143 inhibits autophagy in cytarabine-treated AML cells by directly targeting autophagy-related proteins (ATG), ATG7 and ATG2B, two critical known components of autophagic machinery. More importantly, autophagy reconstructed via co-expression of ATG7 and ATG2B substantially attenuates miR-143-enhanced cytotoxicity, which is associated with suppression of caspase-dependent apoptotic pathway. Overall, this study demonstrates that targeting ATG7 and ATG2B-dependent autophagy is a critical mechanism by which miR-143 sensitizes AML to cytarabine, implicating it as a potential therapeutic target in AML treatment.

Abstract
Over the last few years, we assisted to an increasing knowledge about acute myeloid leukemia (AML) pathobiology. However, outcomes remain unsatisfactory particularly for adult patients over 60 years old. Not surprisingly several cases of therapy-related AML (tAML) and secondary AML, both characterized by poorer prognosis, are more common in older population. For several decades initial therapy for AML remained unchanged and typically treatment consisted of an anthracycline combined with continuous infusion of cytarabine for 7 days, the so-called "7+3" standard regimen. The efforts made by the researchers to improve this standard schedule, have led to only modest improvement in the response rate (RR) but no change in overall survival (OS), until the recent evolution seen with new target specific mutation therapies. In 2017, a new liposomal-encapsulated formulation with daunorubicin and cytarabine (CPX-351) was approved by the US Food and Drug Administration for the treatment of newly diagnosed tAML or AML with myelodysplasia-related changes (AML-MRCs). Based on the findings that ratiometric delivery may be more effective than administration of either drug at their maximum tolerated dose (MTD), CPX-351 was designed to deliver a fixed 5:1 molar ratio of the two molecules historically used in the standard "7+3" regimen, cytarabine and daunorubicin respectively. CPX-351 did show improvements of overall survival compared to traditional "7+3" in newly diagnosed secondary and therapy-related AML in adult patients. However, questions remain regarding how to select across AML patient subgroups to maximize the clinical benefit. Possible future directions include evaluating CPX-351 dose intensification, combining this liposomal formulation with targeted therapies and not least important a better understanding about the mechanism of improved responses in tAML and AML-MRC, two entities recognized to be less chemo-sensitive than other hematologic malignancies. In summary, CPX-351 offers finally something new in the landscape of AML therapy. Herein we will review the rationale behind this new drug product development, the main pharmacological characteristics, and discuss the results of clinical trials that led to its FDA approval at first and by EMA in 2018.

Abstract
12-O-tetradecanoylphorbol-13-acetate (TPA), is a major active constituent of the seed oil of Croton tiglium L., has pharmacological activity for the treatment of acute myeloid leukemia patients. Diethyldithiocarbamate (DTC) is a potent inhibitor of NF-κB show activity of anticancer. In this study, we determined the effect of DTC and TPA in combination on HL-60 cells cultured in vitro and in vivo. In this study, we have shown that DTC and TPA synergistically inhibited the growth of HL-60 cells and strongly induced apoptosis in the cells. Mechanistic studies showed that the combined effects of DTC and TPA were associated with a decrease in Bcl-2. The animal experiment showed that the combination of DTC and TPA more potently inhibited the growth of HL-60 tumors than either agent alone. Our results indicate that the administration of TPA and DTC in combination may be an effective strategy for inhibiting the growth of acute myeloid leukemia cells.

Abstract
Toona sinensis is a common edible vegetable that is used in
certain Chinese dishes and has importance in folk medicine. The leaf extracts of
T sinensis possess and exhibit anticancer efficacy against
various cancer cell types. In Taiwanese folklore, Antrodia
camphorata, also known as “Niu-Cheng-Zi,” is used in traditional
medicine to treat various illnesses. Its fruit and mycelium possess various
potent antiproliferative properties. Two studies from our group have reported
that T sinensis or A camphorata has the
ability to cause apoptosis in various cancer cells. Conversely, underlying
molecular mechanisms and any beneficial effects remain unknown. This study shows
anticancer efficacy for both T sinensis and A
camphorata co-treatments that target HL-60 cells. The combination
index values indicate that 40 µg/mL of T sinensis and 25 µg/mL
of A camphorata as a combined treatment shows a synergetic
effect, which reduces HL-60 cell proliferation. Alternately, this treatment
exhibited no cytotoxic effects for human umbilical vein endothelial cells.
Western blot data showed that T sinensis and A
camphorata as a combined treatment result in augmented expression
of apoptosis, cytochrome c release, Bcl-2 inhibition, expression of Bax, Fas,
and FasL, as well as the cleavage of Bid in HL-60 cells. Moreover, this combined
treatment overshadowed monotherapy in its ability to inhibit uPAR, MMP-9, MMP-2,
COX-2 expression, and PGE2 secretions. Our study strongly implies
that this combined treatment offers more beneficial effects to suppress and
treat leukemia due to apoptosis-mediated cell inhibition. Further in
vivo studies related to the combined treatment could establish its
future potential.

Abstract
Acute myeloid leukemia (AML) is a heterogeneous clonal disease characterized by the proliferation and accumulation of myeloid blast cells in the bone marrow, which eventually lead to hematopoietic failure. Chemoresistance presents as a major burden for therapy of AML patients. p53 is the most important tumor suppressor protein that regulates cellular response to various stress. It is also important for hematopoietic stem cell development and hematopoiesis. Mutation or deletion of TP53 has been found to be linked to cancer progression, therapy-related resistance, and poor prognosis. TP53 mutation occurs in less than 10% of AML patients; however, it represents a subset of AML with therapy resistance and poor outcome. In addition, there is a subgroup of patients with low-frequency TP53 mutations. The percentage ranges from 1% to 3% of all AML patients. These patients have outcomes comparable to those of the high-frequency TP53 mutation patients. TP53-mutated clones isolated from the parental cells exhibit a survival advantage under drug treatment compared with cells with wild-type TP53, and have a higher population of leukemia stem cell (LSC) marker-positive cells, a characteristic of chemo-resistant cells. Therefore, low-frequency TP53 mutation, which is currently underappreciated, is an important prognosis factor for AML patients. Epigenetic drugs, such as hypomethylating agent and histone deacetylase inhibitors, have been found effective in targeting TP53-mutated AML. Histone deacetylase inhibitors can preferentially target the TP53-mutated subpopulation by reactivating p53-targeted genes and by eradicating LSC marker-positive cells. Therefore, combined treatment with epigenetic drugs may represent a new therapeutic strategy for treatments of TP53-mutated AML.

Abstract
On June 28, 2018, the Committee for Medicinal Products for Human Use adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Vyxeos, intended for the treatment of acute myeloid leukemia (AML). Vyxeos was designated as an orphan medicinal product on January 11, 2012. The applicant for this medicinal product was Jazz Pharmaceuticals Ireland Limited. Vyxeos is a liposomal formulation of a fixed combination of daunorubicin and cytarabine, antineoplastic agents that inhibit topoisomerase II activity and also cause DNA damage. The strength of Vyxeos is 5 units/mL, where 1 unit equals 1.0 mg cytarabine plus 0.44 mg daunorubicin. The marketing authorization holder Jazz Pharmaceuticals had found that this was an optimal ratio for the efficacy of the product. Study CLTR0310-301, a phase III, multicenter, randomized, trial of Vyxeos (daunorubicin-cytarabine) liposome injection versus standard 3+7 daunorubicin and cytarabine in patients aged 60-75 years with untreated high-risk (secondary) AML, showed a statistically significant difference between the two groups in overall survival (OS) with a median OS of 9.56 months in the daunorubicin-cytarabine arm compared with 5.95 months for standard chemotherapy (hazard ratio, 0.69; 95% confidence interval, 0.52-0.90; one-sided p = .003). The most common side effects were hypersensitivity including rash, febrile neutropenia, edema, diarrhea/colitis, mucositis, fatigue, musculoskeletal pain, abdominal pain, decreased appetite, cough, headache, chills, arrhythmia, pyrexia, sleep disorders, and hypotension. IMPLICATIONS FOR PRACTICE: Vyxeos has demonstrated a clinically significant improvement in overall survival compared with the standard of care 7+3 in the proposed population of patients with newly diagnosed acute myeloid leukemia (AML) with myelodysplasia-related changes and therapy-related AML. This is remarkable given the very poor prognosis of these patients and their unmet medical need. Secondary endpoints support the primary outcome, in particular an increased rate of hematopoietic stem cell transplantation, which is potentially the only curative treatment in AML.

Abstract
OBJECTIVES Treatment outcome in children with acute myeloid leukemia (AML) has improved in the developed world but remains poor in developing countries. We assessed the role of etoposide in induction chemotherapy in pediatric AML. METHODS This analysis retrospectively compared 2 induction chemotherapy regimens consisting of daunorubicin and cytarabine with etoposide (ADE) and without etoposide (AD). All newly diagnosed cases of AML younger than 18 years from January 1, 2012, onwards who completed their treatment before January 31, 2019, were included. Data of 186 cases, including 117 males (62.9%) and 69 females (37.1%), were analyzed. Demographic, initial presentation blood counts, and AML subtypes were almost identical in both groups. RESULTS Complete remission rates were almost identical for the ADE versus the AD group (78.8% vs 80.0%, p = 0.980). Treatment-related mortality was higher, albeit not significantly, in the ADE (25 of 105; 23.8%) versus the AD (16 of 81; 19.8%) group (p = 0.508). Overall survival was 32 of 105 (30.5%) in the ADE and 43 of 81 (53.1%) in the AD group (p = 0.079), and disease-free survival was 29 of 105 (27.6%) and 39 of 81 (48.1%) in ADE and AD groups (p = 0.056), respectively. CONCLUSIONS Etoposide in induction treatment of pediatric AML is associated with increased episodes of bacterial and fungal infections and high treatment-related mortality. Moreover, it does not offer any survival benefit. In low- and middle-income countries like Pakistan, it should not be used in the induction treatment protocol.

Abstract
Gemtuzumab ozogamicin (GO), an anti-CD33 antibody linked to calicheamicin via an acid-labile linker, is the first antibody-drug conjugate (ADC). The acidic environment inside lysosomes of target cells is an important intracellular determinant of the cytocidal action of GO, as the linker is hydrolyzed under acidic conditions. However, lysosomal activity in acute myeloid leukemia (AML) blasts in GO therapy has been insufficiently evaluated. It has been suggested that lysosome activity is suppressed in AML due to hyperactivation of the phosphoinositide 3-kinase/Akt pathway. We therefore hypothesized that agents which activate lysosomal function would potentiate the cytotoxicity of GO. Here, we found that a clinically useful mTORC1/2 dual inhibitor, AZD2014, reduced pH in the acidic organelles, including lysosomes, as shown by increased LysoTracker fluorescent intensity, and synergistically enhanced the cytotoxic effect of GO in primary leukemia cells. GO-induced cytotoxicity appeared to be enhanced with the increase in lysosomal activity by AZD2014. These results indicate that AZD2014 activated lysosomal function in primary leukemia cells, which in turn enhanced the cytotoxicity of GO. Enhancement of lysosomal activity may represent a new therapeutic strategy in the treatment of GO and other ADCs, particularly in cases with low lysosomal activity.

Abstract
Leukemic stem cells are multipotent, self-renewing, highly proliferative cells that can withstand drug treatments. Although currently available treatments potentially destroy blast cells, they fail to eradicate leukemic progenitor cells completely. Aldehyde dehydrogenase and STAT3 are frequently up-regulated in pre-leukemic stem cells as well as in acute myeloid leukemia (AML) expressing the CD34+CD38− phenotype. The Isatin analog, KS99 has shown anticancer activity against multiple myeloma which may, in part, be mediated by inhibition of Bruton’s tyrosine kinase activation. Here we demonstrate that KS99 selectively targets leukemic stem cells with high aldehyde dehydrogenase activity and inhibits phosphorylation of STAT3. KS99 targeted cells co-expressing CD34, CD38, CD123, TIM-3, or CD96 immunophenotypes in AML, alone or in combination with the standard therapeutic agent cytarabine. AML with myelodysplastic-related changes was more sensitive than de novo AML with or without NPM1 mutation. KS99 treatment reduced the clonogenicity of primary human AML cells as compared to normal cord blood mononuclear cells. Downregulation of phosphorylated Bruton’s tyrosine kinase, STAT3, and aldehyde dehydrogenase was observed, suggesting interaction with KS99 as predicted through docking. KS99 with or without cytarabine showed in vivo preclinical efficacy in human and mouse AML animal models and prolonged survival. KS99 was well tolerated with overall negligible adverse effects. In conclusion, KS99 inhibits aldehyde dehydrogenase and STAT3 activities and causes cell death of leukemic stem cells, but not normal hematopoietic stem and progenitor cells.

Abstract
Objective: To study the expression of CD123 in bone marrow (BM) blasts of acute myeloid leukemia (AML) patients to explore the relationship between CD123 expression and therapeutic response and prognosis. Methods: This study retrospectively analyzed expression and distribution of CD123 in BM blasts in 137 cases of newly diagnosed AML (excluded M(3)) , CD123 detected by flow cytometry≥20% was defined as positive, including 84 CD123(+) AML and 53 CD123(-) AML, efficacy and prognosis were compared between the two groups. Results: ① Among 137 patients, 84 were in group CD123(+) (61.3%) , and 53 in group CD123(-) (38.7%) . All 137 patients were classified into risk groups based on cytogenetic and molecular biology abnormalities. No significant differences were seen between the three risk groups with regard to their CD123 levels (χ(2)=0.861, P=0.650) . Compared with CD123(-) group, the CD123(+) group had higher WBC[47.7 (1.0-264.0) vs 22.4 (0.7-211.0) , z=-2.592, P=0.010]. ② The rates of first complete remission (CR1) and recurrence of CD123(+) group were 54.8% (46/84) and 50.8% (32/63) , respectively; and CD123(-) group were 73.6% (39/53) and 41.7% (20/48) , respectively. There was significant difference of CR1 between the two groups (χ(2)=5.121, P=0.027) , whereas no significant difference of the recurrence rate (χ(2)=0.911, P=0.340) . ③ The median dutations of OS between CD123(+) group and CD123(-) group were 20.0 (95%CI 13.1-26.9) months vs 44.0 (95%CI 23.6-47.3) months, respectively (χ(2)=5.874, P=0.015) ; The median durations of DFS were 7.8 (95%CI 1.4-14.1) months vs 18.6 (95%CI 0-39.7) months, respectively, no differences were observed between the two groups (χ(2)=2.939, P=0.086) . ④ CD123 retained an adverse prognosis value on DFS and OS within the intermediate group and patients ≤ 50 years older. Conclusions: CD123 widely expressed in AML patients, which was an independent risk factor for CR1 and OS, which implicating its important role in evaluating the induction chemotherapy response and prognosis of AML.

Histone deacetylase inhibitor targets CD123/CD47-positive cells and reverse chemoresistance phenotype in acute myeloid leukemia. Leukemia 2018; 33:931-944.

Abstract
Chemoresistance may be due to the survival of leukemia stem cells (LSCs) that are quiescent and not responsive to chemotherapy or lie on the intrinsic or acquired resistance of the specific pool of AML cells. Here, we found, among well-established LSC markers, only CD123 and CD47 are correlated with AML cell chemosensitivities across cell lines and patient samples. Further study reveals that percentages of CD123+CD47+ cells significantly increased in chemoresistant lines compared to parental cell lines. However, stemness signature genes are not significantly increased in resistant cells. Instead, gene changes are enriched in cell cycle and cell survival pathways. This suggests CD123 may serve as a biomarker for chemoresistance, but not stemness of AML cells. We further investigated the role of epigenetic factors in regulating the survival of chemoresistant leukemia cells. Epigenetic drugs, especially histone deacetylase inhibitors (HDACis), effectively induced apoptosis of chemoresistant cells. Furthermore, HDACi Romidepsin largely reversed gene expression profile of resistant cells and efficiently targeted and removed chemoresistant leukemia blasts in xenograft AML mouse model. More interestingly, Romidepsin preferentially targets CD123+ cells, while chemotherapy drug Ara-C mainly targeted fast-growing, CD123- cells. Therefore, Romidepsin alone or in combination with Ara-C may be a potential treatment strategy for chemoresistant patients.

Abstract
INTRODUCTION Acute myeloid leukemia (AML) remains a poor prognosis hematological malignancy. The introduction of aggressive chemotherapy with allogeneic stem cell transplantation has resulted in improved clinical outcomes in younger patients. However, the treatment results in unfit elderly AML population remain disappointing. New strategies should be introduced to improve the prognosis in this group of patients. Areas covered: This review presents and discusses the mechanism of action, safety and efficacy of sapacitabine in AML patients. Expert opinion: Sapacitabine, a novel nucleoside analog, seemed to be a promising new agent for AML treatment. Its oral bioavailability and tolerable toxicity profile allow the drug to be used in an outpatient setting, especially in elderly unfit patients. Sapacitabine is known to have antileukemic activity in randomized clinical trials. In AML patients, sapacitabine monotherapy offered no advantage over low-intensity cytarabine treatment, and the combination of sapacitabine with decitabine was not significantly more effective than decitabine alone. However, the oral administration of sapacitabine allows it to be used in AML maintenance therapy.

Abstract
Cantharidin, a natural toxin from blister beetles, has shown potent anticancer activities on many solid tumor cells. Recently, cantharidin and its analogue, norcantharidin, were also shown to suppress nonsolid tumors such as chronic myeloid leukemia, acute myeloid leukemia (AML), and leukemic stem cells. However, there is no available information to address the effects of cantharidic acid (CAC), a hydrolysis product of cantharidin, on human AML cells. The present study showed that CAC, at a range of concentrations (0-20 μM), concentration-dependently inhibited cell proliferation in the HL-60 AML cell line. Western blot and flow cytometric assays demonstrated that CAC induced several features of apoptosis such as sub G1-phase cell increase, phosphatidylserine (PS) externalization, and significantly activated proapoptotic signaling including caspase-8, -9, and -3 activation and poly(ADP-ribose) polymerase (PARP) cleavage in HL-60 AML cells. Moreover, treatment of HL-60 cells with CAC induced concentration- and time- dependent activation of p38 mitogen-activated protein kinase (p38 MAPK) and c-Jun N-terminal kinase (JNK). Only JNK-, but not p38 MAPK-specific inhibitor can reverse the CAC-induced activation of the caspase-8, -9, and -3. We concluded that CAC can induce apoptosis in human leukemic HL-60 cells via a caspases-dependent pathway, and that the apoptosis-inducing effect of CAC can be regulated by JNK activation signaling.

Abstract
Activation of the Protein Kinase B (PKB), or AKT pathway has been shown to correlate with acute myeloid leukemia (AML) prognosis. B55α-Protein Phosphatase 2A (PP2A) has been shown to dephosphorylate AKT at Thr-308 rendering it inactive. In fact, low expression of the PP2A regulatory subunit B55α was associated with activated phospho-AKT and correlated with inferior outcomes in AML. Despite this fact, no studies have specifically demonstrated a mechanism whereby B55α expression is regulated in AML. In this study, we demonstrate novel loss of function mutations in the PPP2R2A gene identified in leukemic blasts from three AML patients. These mutations eliminate B55α protein expression thereby allowing constitutive AKT activation. In addition, leukemic blasts with PPP2R2A gene mutation were more sensitive to treatment with the AKT inhibitor MK2206, but less responsive to the PP2A activator FTY720. Using leukemia cell lines, we further demonstrate that B55α expression correlates with AKT Thr-308 phosphorylation and predicts responsiveness to AKT inhibition and PP2A activation. Together our data illustrate the importance of the B55α-PP2A-AKT pathway in leukemogenesis. Screening for disruptions in this pathway at initial AML diagnosis may predict response to targeted therapies against AKT and PP2A.

Abstract
Numerous clinical studies of vitamin D, its derivatives or analogs, have failed to clearly demonstrate sustained benefits when used for the treatment of human malignant diseases. However, given the strong preclinical evidence of anti-neoplastic activity and the epidemiological associations suggesting that vitamin D compounds may have a place in cancer therapy, attempts are continuing to devise new approaches to their therapeutic use. This laboratory has developed a strategy to enhance the effectiveness of the currently standard therapy of Acute Myeloid Leukemia (AML) by the immediate addition of the vitamin D2 analog Doxercalciferol combined with the plant polyphenol-derived Carnosic acid to AML cells previously treated with Cytarabine (AraC). Enhancement of AML cell death was noted to be dependent on VDR and BRAF kinase. Here we document that the stress-related kinase JNK is an important additional component of cell death enhancement in this protocol. Either the Knock-down or the inhibition of JNK activity reduced the enhancement of AraC-induced cell death, and we show that JNK signaling to the apoptosis regulator BIM and Caspase executioners of cell death are downstream of VDR and BRAF. A clear understanding of the molecular basis for the increased efficacy of AraC in the therapy of AML is expected to bring this regimen to a clinical trial.

Abstract
The CD13 antigen's binding site for the Asn-Gly-Arg (NGR) motif enables NGR-containing chemotherapeutic drugs to be delivered to CD13-positive tumours. Human CD13-positive acute myeloid leukemia (AML) cells proliferate abnormally and escape death. Here, we show that the CNGRC-GG-D(KLAKLAK)2 peptide induces death in AML cell lines (U937, THP-1, NB4, HL-60) and primary blood cells from AML patients. Cell death was characterized as a caspase-independent mechanism, without DNA fragmentation, but phosphatidylserine externalization and membrane disruption. Our results demonstrate in U937 cells that (i) the NGR-peptide triggers the loss of mitochondrial potential(ΔΨm) and generates superoxide anion (O2-), (ii) N-acetyl-L-cysteine (NAC) and extra/intracellular Ca2+ chelators (BAPTA) prevent both O2- production and cell death, (iii) the Ca2+-channel blocker nifedipine prevents cell death (indicating that Ca2+ influx is the initial death trigger), and (iv) BAPTA, but not NAC, prevents ΔΨm loss (suggesting O2- is a mitochondrial downstream effector). AML cell lines and primary blasts responding to the lethal action of NGR-peptide express promatrix metalloproteinase-12 (proMMP-12) and its substrate progranulin (an 88 kDa cell survival factor). A cell-free assay highlighted proMMP-12 activation by O2-. Accordingly, NGR-peptide's downregulation of 88 kDa progranulin protein was prevented by BAPTA and NAC. Conversely, AML blast resistance to NGR-peptide is associated with the expression of a distinct, 105 kDa progranulin isoform. These results indicate that CNGRC-GG-D(KLAKLAK)2 induces death in AML cells through the Ca2+-mitochondria-O2.-pathway, and support the link between proMMP-12 activation and progranulin cleavage during cell death. Our findings may have implications for the understanding of tumour biology and treatment.

The combination of CHK1 inhibitor with G-CSF overrides cytarabine resistance in human acute myeloid leukemia. Nat Commun 2017; 8:1679.

Abstract
Cytarabine (AraC) represents the most effective single agent treatment for AML. Nevertheless, overriding AraC resistance in AML remains an unmet medical need. Here we show that the CHK1 inhibitor (CHK1i) GDC-0575 enhances AraC-mediated killing of AML cells both in vitro and in vivo, thus abrogating any potential chemoresistance mechanisms involving DNA repair. Importantly, this combination of drugs does not affect normal long-term hematopoietic stem/progenitors. Moreover, the addition of CHK1i to AraC does not generate de novo mutations and in patients' samples where AraC is mutagenic, addition of CHK1i appears to eliminate the generation of mutant clones. Finally, we observe that persistent residual leukemic cells are quiescent and can become responsive to the treatment when forced into cycle via granulocyte colony-stimulating factor (G-CSF) administration. This drug combination (AraC+CHK1i+G-CSF) will open the doors for a more efficient treatment of AML in the clinic.

Abstract
Toona sinensis (TS) is one of the most popular vegetarian dishes in Taiwan. It has been shown to exhibit antioxidant, antiangiogenic, antiatherosclerotic, and anticancer properties. In this study, we demonstrated the ability of aqueous leaf extracts from TS to promote immune responses in BALB/c mice and to exhibit anti-leukemia activity in murine WEHI-3 cells. BALB/c mice were injected intravenously with WEHI-3 cells and then treated orally with TS (50 mg/kg). In vivo study showed that TS treatment reduced liver and spleen enlargement in WEHI-3 bearing mice compared with the untreated group. Furthermore, TS also decreased white blood cells (WBC), indicating inhibition of differentiation of the precursor of macrophages in WEHI-3 bearing mice. Treatment of WEHI-3 cells with TS (0-75 μg/mL for 24 hours) significantly reduced cell viability. Furthermore, TS treatment-induced late apoptosis was confirmed by Annexin-V/PI staining. Western blot analyses revealed that treatment of WEHI-3 cells with TS statistically increased the protein expression level of cytochrome c in the cytoplasm and activates caspase-3. Notably, TS treatment caused a dramatic reduction in Bcl-2 and increase in Bax protein levels. TS may disturb the Bcl-2 and Bax protein ratio and induce apoptosis. This reports confirms the antitumor activity of this nutritious vegetable potentially against leukemia.

Abstract
BACKGROUND Acute myeloid leukemia (AML) is one of the most common types of leukemia in adults, but there is limited information on survivors' quality of life (QOL) after remission. OBJECTIVE We piloted a survey exploring patient-reported outcomes for people with AML in first complete remission (CR1) to determine whether patients felt the survey is relevant to their well-being and to summarize patient characteristics. DESIGN/MEASUREMENTS Cross-sectional survey of a convenience sample of AML patients in CR1 assessing QOL and functioning (European Organization for Research and Treatment of Cancer [EORTC] QLQ-C30 v 3.0), well-being (QOL-cancer survivor [QOL-CS]), fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue [FACIT-Fatigue]), and anxiety and depression (hospital anxiety and depression scale [HADS]). The survey contained five open-ended questions. RESULTS Eighteen patients completed the survey. Most felt it was completely or mostly relevant (88.8%) in describing their QOL. Participants scored well on the EORTC QLQ-C30, fatigue being the most common symptom (83%).The FACIT-Fatigue mean score was 28.7 and median score was 33.5 (normal ≥30). Two scored in the abnormal range for anxiety and one for depression on the HADS. On the QOL-CS, participants scored more than 6 out of 10 in most domains, except the subscales of distress and fear. CONCLUSIONS The survey content and length were appropriate. Patients reported ongoing fatigue, fears of future test results, getting a second cancer, and recurrence of cancer. Survivors experience ongoing symptoms, highlighting the importance of providers performing ongoing symptom and needs assessments.

Abstract
Chimeric antigen receptor (CAR)-redirected T lymphocytes are a promising immunotherapeutic approach and object of pre-clinical evaluation for the treatment of acute myeloid leukemia (AML). We developed a CAR against CD123, overexpressed on AML blasts and leukemic stem cells. However, potential recognition of low CD123-positive healthy tissues, through the on-target, off-tumor effect, limits safe clinical employment of CAR-redirected T cells. Therefore, we evaluated the effect of context-dependent variables capable of modulating CAR T cell functional profiles, such as CAR binding affinity, CAR expression, and target antigen density. Computational structural biology tools allowed for the design of rational mutations in the anti-CD123 CAR antigen binding domain that altered CAR expression and CAR binding affinity without affecting the overall CAR design. We defined both lytic and activation antigen thresholds, with early cytotoxic activity unaffected by either CAR expression or CAR affinity tuning but later effector functions impaired by low CAR expression. Moreover, the anti-CD123 CAR safety profile was confirmed by lowering CAR binding affinity, corroborating CD123 is a good therapeutic target antigen. Overall, full dissection of these variables offers suitable anti-CD123 CAR design optimization for the treatment of AML.

Abstract
Idarubicin (IDR), cytarabine (AraC), and tamibarotene (Am80) are effective for treatment of acute myeloid leukemia (AML). In acute leukemia, the incidence of venous thromboembolism or disseminated intravascular coagulation is associated with induction chemotherapy. Procoagulant effects of IDR, AraC, and Am80 were investigated in a vascular endothelial cell line EAhy926 and AML cell lines HL60 (AML M2), NB4 (AML M3, APL), and U937 (AML M5), focusing on tissue factor (TF), phosphatidylserine (PS), and thrombomodulin (TM). IDR induced procoagulant activity on the surface of vascular endothelial and AML cell lines. Expression of TF antigen, TM antigen, and PS were induced by IDR on the surface of each cell line, whereas expression of TF and TM mRNAs were unchanged. Conversely, Am80 decreased TF exposure and procoagulant activity, and increased TM exposure on NB4 cells. In NB4 cells, we observed downregulation of TF mRNA and upregulation of TM mRNA. These data suggest IDR may induce procoagulant activity in vessels by apoptosis through PS exposure and/or TF expression on vascular endothelial and AML cell lines. Am80 may suppress blood coagulation through downregulation of TF expression and induction of TM expression. Our methods could be useful to investigate changes in procoagulant activity induced by antineoplastic drugs.

Abstract
Adenosquamous carcinoma of the breast is a rare cancer that develops as glands and tubules admixed with solid nests of squamous cells in a spindle cell background. Furthermore, its occurrence following AML is also rare. To the best of our knowledge, based on a review of the relevant literature, thus far there have not been any welldocumented cases. In the present case report, we report on a middle-aged woman with a 2year history of acute myeloid leukemia (AML) who was admitted to hospital due to a mass in the right breast, with concurrent cutaneous lesions on the breast. The clinical and pathological investigations resulted in the diagnosis of adenosquamous carcinoma of the breast. The patient underwent a modified radical mastectomy (MRM). Subsequently, the patient received chemotherapy, involved-field radiation therapy and target therapy. At 9 months after the final cycle of chemotherapy, and while she was on targeted therapy with trastuzumab (6 mg administered every 3 weeks), the patient presented with extensive dermatomal skin lesions. A biopsy report revealed metastatic lesions of invasive ductal carcinoma in the abdomen, so chemotherapy resumed with a course lasting for 6 cycles, with the identical treatments, but lacking trastuzumab.

Abstract
Increasingly, peripherally inserted central catheters (PICC) are applied in patients with haematological malignancies. The feasibility and safety of PICC for induction chemotherapy in acute myeloid leukaemia (AML) remain unclear. Medical records of 89 newly diagnosed adult de novo AML patients, who achieved complete remission, were retrospectively reviewed (PICC group, n = 43; intravenous [IV] line group, n = 46). Patients' clinical characteristics and the number of blind punctures for blood sampling were compared between these two groups, and risk factors associated with bacteraemia were identified by univariate analysis. Patients in the PICC group experienced significantly fewer blind punctures than those in the IV line group (3.3 ± 3.6 vs. 14.4 ± 6.0; p = .000); 20.9% of PICC patients had bacteraemia, compared with 23.9% in the IV line group (p = .803). Most patients (76.7%) removed their PICC because treatment was completed. PICC increased the quality of life in AML patients undergoing chemotherapy induction by reducing the number of blind blood punctures required. Bacteraemia in PICC patients was comparable to that in IV line patients. PICC is, therefore, a feasible and safe central venous device for use in AML patients.

Abstract
PURPOSE Selinexor, a selective inhibitor of XPO1, is currently being tested as single agent in clinical trials in acute myeloid leukemia (AML). However, considering the molecular complexity of AML, it is unlikely that AML can be cured with monotherapy. Therefore, we asked whether adding already established effective drugs such as topoisomerase (Topo) II inhibitors to selinexor will enhance its anti-leukemic effects in AML. EXPERIMENTAL DESIGN The efficacy of combinatorial drug treatment using Topo II inhibitors (idarubicin, daunorubicin, mitoxantrone, etoposide) and selinexor was evaluated in established cellular and animal models of AML. RESULTS Concomitant treatment with selinexor and Topo II inhibitors resulted in therapeutic synergy in AML cell lines and patient samples. Using a xenograft MV4-11 AML mouse model, we show that treatment with selinexor and idarubicin significantly prolongs survival of leukemic mice compared with each single therapy. CONCLUSIONS Aberrant nuclear export and cytoplasmic localization of Topo IIα has been identified as one of the mechanisms leading to drug resistance in cancer. Here, we show that in a subset of patients with AML that express cytoplasmic Topo IIα, selinexor treatment results in nuclear retention of Topo IIα protein, resulting in increased sensitivity to idarubicin. Selinexor treatment of AML cells resulted in a c-MYC-dependent reduction of DNA damage repair genes (Rad51 and Chk1) mRNA and protein expression and subsequent inhibition of homologous recombination repair and increased sensitivity to Topo II inhibitors. The preclinical data reported here support further clinical studies using selinexor and Topo II inhibitors in combination to treat AML. Clin Cancer Res; 22(24); 6142-52. ©2016 AACR.

Abstract
Human cytidine deaminase (hCDA) is a biomedically important enzyme able to inactivate cytidine nucleoside analogs such as the antileukemic agent cytosine arabinoside (AraC) and thereby limit antineoplastic efficacy. Potent inhibitors of hCDA have been developed, e.g. zebularine, that when administered in combination with AraC enhance antineoplastic activity. Tandem hematopoietic stem cell (HSC) transplantation and combination chemotherapy (zebularine and AraC) could exhibit robust antineoplastic potency, but AraC-based chemotherapy regimens lead to pronounced myelosuppression due to relatively low hCDA activity in HSCs, and this approach could exacerbate this effect. To circumvent the pronounced myelosuppression of zebularine and AraC combination therapy while maintaining antineoplastic potency, zebularine-resistant hCDA variants could be used to gene-modify HSCs prior to transplantation. To achieve this, our approach was to isolate hCDA variants through random mutagenesis in conjunction with selection for hCDA activity and resistance to zebularine in an Escherichia coli genetic complementation system. Here, we report the identification of nine novel variants from a pool of 1.6 × 106 transformants that conferred significant zebularine resistance relative to wild-type hCDA2. Several variants revealed significantly higher Ki values toward zebularine when compared with wild-type hCDA values and, as such, are candidates for further exploration for gene-modified HSC transplantation approaches.

Novel analogs of 1,25-dihydroxyvitamin D 2 combined with a plant polyphenol as highly efficient inducers of differentiation in human acute myeloid leukemia cells. J Steroid Biochem Mol Biol 2016; 164:59-65. [PMID: 26365556 DOI: 10.1016/j.jsbmb.2015.09.014] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2015] [Revised: 09/02/2015] [Accepted: 09/08/2015] [Indexed: 12/19/2022]
Abstract
1α,25-Dihydroxyvitamin D3 [1,25(OH)2D3] is known to act as a powerful differentiation inducer in various types of cancer cells, including acute myeloid leukemia (AML) cells. However, supraphysiological concentrations of 1,25(OH)2D3 required to induce terminal maturation of AML cells can cause lethal hypercalcemia in vivo. Here we characterized the differentiation-inducing effects of novel double-point modified analogs of 1,25-dihydroxyvitamin D2 [1,25(OH)2D2], PRI-5201 and PRI-5202 [Pietraszek et al. (2013) Steroids, 78:1003-1014], on HL60, U937 and MOLM-13 human AML cells in comparison with their direct precursors (PRI-1906 and PRI-1907, respectively) and 1,25(OH)2D3. The results demonstrated the following order of potency for the tested compounds: PRI-5202>PRI-1907>PRI-5201>PRI-1906≥1,25(OH)2D3, as determined by measuring the expression of cell surface markers of myeloid differentiation. Particularly, the sensitivity of different AML cell lines to PRI-5201 and PRI-5202 was 3-15-fold and 13-50 fold higher, respectively, compared to that of 1,25(OH)2D3. Importantly, all the analogs tested at 0.25-1nM concentrations retained the ability of 1,25(OH)2D3 to cooperate with the rosemary polyphenol carnosic acid, which strongly potentiated their prodifferentiation activity in a cell type-dependent manner. These synergistic effects were associated with increased induction of the vitamin D receptor (VDR) protein expression. However, surprisingly, carnosic acid was able to significantly enhance only 1,25(OH)2D3-induced transactivation of the direct repeat 3 (DR3)-type vitamin D response element (VDRE), whereas no such cooperation was seen with 1,25(OH)2D2 analogs. Furthermore, dose-response analysis revealed that 1,25(OH)2D3 was more efficacious than the analogs in inducing VDRE activation. This suggests that the superior prodifferentiation activity of the analogs, as compared to 1,25(OH)2D3, may be due to their potential for enhanced activation of the differentiation-related VDRE(s) that differ from the DR3-type element tested in this study. Collectively, the results demonstrate that the new double-point modified 1,25(OH)2D2 analogs are much stronger inducers of myeloid differentiation than 1,25(OH)2D3 and that their efficacy can be further enhanced by combination with plant polyphenols. These combinations warrant their further mechanistic and translational exploration in AML and other types of cancer.

Abstract
Realgar (As4S4) has been demonstrated to be effective for the treatment of acute myeloid leukemia (AML); it has the advantages of no drug resistance and oral administration. Nevertheless, its poor solubility has been an obstacle to its bioavailability, requiring high-dose administration over a long period. We investigated whether crushing realgar crystals to the nanoscale and encapsulating the particles in a water-soluble polymer in one step using hot-melt extrusion would increase the bioavailability of As4S4. Raw As4S4 (r-As4S4) and water-soluble polymer were processed via co-rotating twin screw extrusion. The resulting product (e-As4S4) was characterized by SEM, XRD, and DLS. The cytotoxicity and therapeutic effects of e-As4S4 were evaluated in vivo and in vitro. The results show that e-As4S4 dissolved rapidly in water, forming a stable colloid solution. The average size of e-As4S4 particles was 680 nm, which was reduced by more than 40-fold compared with that of r-As4S4. The bioavailability of e-As4S4 was up to 12.6-fold higher than that of r-As4S4, and it inhibited the proliferation of HL-60 cells much more effectively than did r-As4S4, inducing apoptosis and significantly reducing the infiltration of HL-60 cells into the bone marrow, spleen, and liver. This in turn prolonged the survival of AML mice.

Abstract
Acute myeloid leukemia (AML) is an aggressive malignancy, and development of new treatments to prolong remissions is warranted. Chimeric antigen receptor (CAR) T-cell therapies appear promising but on-target, off-tumor recognition of antigen in healthy tissues remains a concern. Here we isolated a high-affinity (HA) folate receptor beta (FRβ)-specific single-chain variable fragment (2.48 nm KD) for optimization of FRβ-redirected CAR T-cell therapy for AML. T cells stably expressing the HA-FRβ CAR exhibited greatly enhanced antitumor activity against FRβ(+) AML in vitro and in vivo compared with a low-affinity FRβ CAR (54.3 nm KD). Using the HA-FRβ immunoglobulin G, FRβ expression was detectable in myeloid-lineage hematopoietic cells; however, expression in CD34(+) hematopoietic stem cells (HSCs) was nearly undetectable. Accordingly, HA-FRβ CAR T cells lysed mature CD14(+) monocytes, while HSC colony formation was unaffected. Because of the potential for elimination of mature myeloid lineage, mRNA CAR electroporation for transient CAR expression was evaluated. mRNA-electroporated HA-FRβ CAR T cells retained effective antitumor activity in vitro and in vivo. Together, our results highlight the importance of antibody affinity in target protein detection and CAR development and suggest that transient delivery of potent HA-FRβ CAR T cells is highly effective against AML and reduces the risk for long-term myeloid toxicity.
