Abstract
Despite its often low efficacy and high toxicity, the standard treatment for acute myeloid leukemia (AML) is induction chemotherapy with cytarabine and idarubicin. Here, we have investigated the role of transporters and drug-metabolizing enzymes in this poor outcome. The expression levels (RT-qPCR) of potentially responsible genes in blasts collected at diagnosis were related to the subsequent response to two-cycle induction chemotherapy. The high expression of uptake carriers (ENT2), export ATP-binding cassette (ABC) pumps (MDR1), and enzymes (DCK, 5-NT, and CDA) in the blasts was associated with a lower response. Moreover, the sensitivity to cytarabine in AML cell lines was associated with ENT2 expression, whereas the expression of ABC pumps and enzymes was reduced. No ability of any AML cell line to export idarubicin through the ABC pumps, MDR1 and MRP, was found. The exposure of AML cells to cytarabine or idarubicin upregulated the detoxifying enzymes (5-NT and DCK). In AML patients, 5-NT and DCK expression was associated with the lack of response to induction chemotherapy (high sensitivity and specificity). In conclusion, in the blasts of AML patients, the reduction of the intracellular concentration of the active metabolite of cytarabine, mainly due to the increased expression of inactivating enzymes, can determine the response to induction chemotherapy.

MPT0B169, a novel tubulin inhibitor, induces apoptosis in taxol-resistant acute myeloid leukemia cells through mitochondrial dysfunction and Mcl-1 downregulation. Tumour Biol 2015; 37:6065-72.

Abstract
Acute myeloid leukemia (AML) is a hematological malignant disorder. AML cells are not susceptible to chemotherapeutic drugs because of their multidrug resistance (MDR). Antitubulin agents are currently employed in cancer treatments; however, drug resistance results in treatment failures because of MDR1 expressing cancer cells. We previously synthesized a new tubulin inhibitor, 2-dimethylamino-N-[1-(4-methoxy-benzenesulfonyl)-2,3-dihydro-1H-indol-7-yl]-acetamide (MPT0B169), which inhibits AML cell proliferation by arresting cell cycle at the G2/M phase. In this study, we explored the effect of MPT0B169 on apoptosis in AML HL60 and NB4 cells and MDR1-mediated taxol-resistant HL60/TaxR cells and the underlying mechanism. MPT0B169 induced concentration- and time-dependent apoptosis in these cancer cells, as observed through annexin V/propidium iodide double staining and flow cytometry. Furthermore, DNA fragmentation analysis confirmed MPT0B169-induced apoptosis. MPT0B169 induced a loss of mitochondrial membrane potential, release of cytochrome c into the cytosol, cleavage and activation of caspase-9 and caspase-3, and consequently cleavage of poly (ADP ribose) polymerase. Western blot analysis showed that MPT0B169 markedly reduced Mcl-1 (an antiapoptotic protein) levels; however, it caused no changes in Bcl-2 or BAX (a proapoptotic protein). Knockdown of Mcl-1 using small interfering RNA (siRNA) slightly induced growth inhibition and apoptosis in the HL60 and HL60/TaxR cells. Further investigation revealed that Mcl-1 siRNA enhanced the sensitivity of HL60 and HL60/TaxR cells to MPT0B169-induced growth inhibition and apoptosis. Together, these results demonstrated that MPT0B169-induced apoptosis in nonresistant and MDR1-mediated taxol-resistant AML cells through Mcl-1 downregulation and a mitochondria-mediated pathway. MPT0B169 can overcome MDR1-mediated drug resistance in AML cells.

Role of drug transport and metabolism in the chemoresistance of acute myeloid leukemia. Blood Rev 2015; 30:55-64. [PMID: 26321049 DOI: 10.1016/j.blre.2015.08.001] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2015] [Revised: 08/04/2015] [Accepted: 08/10/2015] [Indexed: 01/18/2023]
Abstract
Acute myeloid leukemia is a clonal but heterogeneous disease differing in molecular pathogenesis, clinical features and response to chemotherapy. This latter frequently consists of a combination of cytarabine and anthracyclines, although etoposide, demethylating agents, and other drugs are also used. Unfortunately, chemoresistance is a common and serious problem. Multiple mechanisms account for impaired effectiveness of drugs and reduced levels of active agents in target cells. The latter can be due to lower drug uptake, increased export or decreased intracellular proportion of active/inactive agent due to changes in the expression/function of enzymes responsible for the activation of pro-drugs and the inactivation of active agents. Characterization of the "resistome", or profile of expressed genes accounting for multi-drug resistance (MDR) phenotype, would permit to predict the lack of response to chemotherapy and would help in the selection of the best pharmacological regime for each patient and moment, and to develop strategies of chemosensitization.

Revealing the fate of cell surface human P-glycoprotein (ABCB1): The lysosomal degradation pathway. BIOCHIMICA ET BIOPHYSICA ACTA-MOLECULAR CELL RESEARCH 2015; 1853:2361-70. [PMID: 26057472 DOI: 10.1016/j.bbamcr.2015.06.001] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/30/2015] [Revised: 06/02/2015] [Accepted: 06/04/2015] [Indexed: 12/24/2022]
Abstract
P-glycoprotein (P-gp) transports a variety of chemically dissimilar amphipathic compounds including anticancer drugs. Although mechanisms of P-gp drug transport are widely studied, the pathways involving its internalization are poorly understood. The present study is aimed at elucidating the pathways involved in degradation of cell surface P-gp. The fate of P-gp at the cell surface was determined by biotinylating cell surface proteins followed by flow cytometry and Western blotting. Our data shows that the half-life of endogenously expressed P-gp is 26.7±1.1 h in human colorectal cancer HCT-15 cells. Treatment of cells with Bafilomycin A1 (BafA1) a vacuolar H+ ATPase inhibitor increased the half-life of P-gp at the cell surface to 36.1±0.5 h. Interestingly, treatment with the proteasomal inhibitors MG132, MG115 or lactacystin alone did not alter the half-life of the protein. When cells were treated with both lysosomal and proteasomal inhibitors (BafA1 and MG132), the half-life was further prolonged to 39-50 h. Functional assays done with rhodamine 123 or calcein-AM, fluorescent substrates of P-gp, indicated that the transport function of P-gp was not affected by either biotinylation or treatment with BafA1 or proteasomal inhibitors. Immunofluorescence studies done with the antibody against lysosomal marker LAMP1 and the P-gp-specific antibody UIC2 in permeabilized cells indicated that intracellular P-gp is primarily localized in the lysosomal compartment. Our results suggest that the lysosomal degradation system could be targeted to increase the sensitivity of P-gp- expressing cancer cells towards chemotherapeutic drugs.

Low MDR1 and BAALC expression identifies a new subgroup of intermediate cytogenetic risk acute myeloid leukemia with a favorable outcome. Blood Cells Mol Dis 2014; 53:144-8.

Abstract
Treatment optimization in acute myeloid leukemia requires the accurate assignment of patients at diagnosis to specific risk groups to guide subsequent risk-adapted treatment stratification. In this study, we have evaluated the impact of expression of the gene BAALC in conjunction with MDR1 in AML with intermediate cytogenetic risk group to more precisely define risk assessment. Low MDR1/high BAALC, high MDR1/low BAALC, and high MDR1/high BAALC expressers demonstrated a similar clinical outcome with CR rate being 68.75-75% and relapse rate being 40-50% and therefore could be considered as a "combined group". In contrast, low expression of both BAALC and MDR1 identifies an intermediate cytogenetic risk group a distinctly favorable outcome, with higher CR rate being 93.3%, lower relapse rate being 7.1%, and longer OS being 50.3% than that of the "combined group". Moreover, low MDR1/low BAALC expressers in the intermediate cytogenetic risk group also demonstrated a comparable clinical outcome with patients in the favorable-risk group. Thus low MDR1/low BAALC expression identifies a subgroup of intermediate cytogenetic risk AML patients with a remarkably good long-term outcome achieved by chemotherapy alone.

Distinct poor prognostic subgroups of acute myeloid leukaemia, FLT3-ITD and P-glycoprotein-positive, have contrasting levels of FOXO1. Leuk Res 2013; 38:131-7.

Abstract
Regulation of ABCB1 (P-glycoprotein/Pgp) in AML was investigated. In a historical cohort with Pgp and transcriptional regulator expression profiling data available (n=141), FOXO1 correlated with Pgp protein expression. This was confirmed in an independent cohort (n=204). Down-regulation (siRNA) or hyperactivation (nicotinamide) of FOXO1 led to corresponding changes in Pgp. Low FOXO1 expression correlated with FLT3-ITDs (p<0.001) and siRNA inhibition of FLT3-ITD up-regulated FOXO1. As FOXO1 is a key growth regulator, it may underpin biological differences between Pgp-positive clones (low WBC and primary resistant disease) and clones with a FLT3-ITD (associated with a high WBC and early relapse).

Abstract
Aim: To investigate whether idarubicin in a cytarabine-based induction regimen was superior to daunorubicin in de novo acute myeloid leukemia patients expressing high MDR1. Patients & methods: The clinicopathological data were analyzed in 125 patients receiving daunorubicin or idarubicin with cytarabine for remission induction. Median MDR1 mRNA expression in pretreated bone marrow cells was used as the cutoff point for high and low MDR1 expression. Results: A total of 59.7% high and 77.8% low MDR1 expressers achieved complete remission (CR; p = 0.029). Idarubicin yielded a higher CR rate than daunorubicin in high MDR1 expressers (82.1 vs 41.2%; p = 0.001), it also demonstrated a higher CR rate than daunorubicin (p < 0.05) in high MDR1 expressers exhibiting favorable or intermediate risk, while there was no difference between the two treatment arms in low MDR1 expressers exhibiting either favorable or intermediate risk. Conclusion: Idarubicin is associated with better remission induction of de novo acute myeloid leukemia patients with high MDR1 expression.

Abstract
Erlotinib was originally developed as an epidermal growth factor receptor (EGFR)-specific inhibitor for the treatment of solid malignancies, yet also exerts significant EGFR-independent antileukemic effects in vitro and in vivo. The molecular mechanisms underlying the clinical antileukemic activity of erlotinib as a standalone agent have not yet been precisely elucidated. Conversely, in preclinical settings, erlotinib has been shown to inhibit the constitutive activation of SRC kinases and mTOR, as well as to synergize with the DNA methyltransferase inhibitor azacytidine (a reference therapeutic for a subset of leukemia patients) by promoting its intracellular accumulation. Here, we show that both erlotinib and gefitinib (another EGFR inhibitor) inhibit transmembrane transporters of the ATP-binding cassette (ABC) family, including P-glycoprotein (P-gp), multidrug resistance-associated proteins (MRPs) and breast cancer resistance protein (BCRP), also in acute myeloid leukemia (AML) cells that do not overexpress these pumps. Thus, inhibition of drug efflux by erlotinib and gefitinib selectively exacerbated (in a synergistic or additive fashion) the cytotoxic response of KG-1 cells to chemotherapeutic agents that are normally extruded by ABC transporters (e.g., doxorubicin and etoposide). Erlotinib limited drug export via ABC transporters by multiple mechanisms, including the downregulation of surface-exposed pumps and the modulation of their ATPase activity. The effects of erlotinib on drug efflux and its chemosensitization profile persisted in patient-derived CD34+ cells, suggesting that erlotinib might be particularly efficient in antagonizing leukemic (stem cell) subpopulations, irrespective of whether they exhibit or not increased drug efflux via ABC transporters.
