curcumin and Precursor-Cell-Lymphoblastic-Leukemia-Lymphoma

Acute lymphoblastic leukemia (ALL) is a hematological malignancy of lymphoid progenitor cells associated with excessive proliferation of lymphocytes. Curcumin, a polyphenolic compound, is known to possess anticancer activity. However, the mechanism of apoptosis induction differs in cancers. In this study, we discuss the potential apoptosis and anticancer effect of curcumin on the ALL. After choosing Medical Subject Headings (MeSH) keywords, including "Curcumin", "acute lymphoblastic leukemia", "apoptosis", as well as searching Medline/PubMed, Scopus, Sciencedirect. hand searching in key journals, list of references of selected articles and gray literature, without time and language limitation, articles up to December 2017 were entered into this review. In this review, 244 articles were acquired at the primary search. Study selection and quality assessment processes were done based on Cochrane library guidelines. According to six articles that were selected, curcumin could enhance the antitumor activity of chemotherapy drugs such as L-asparaginase. Curcumin induces apoptosis in Pre B- ALL and T- ALL cells by decreased NF-kB levels, increased p53 levels, PARP-1 cleavage. Also, the induction of growth-arrest and apoptosis in association with the blockade of constitutively active JAK-STAT pathway suggests this be a mechanism by curcumin. Curcumin could be used for the treatment of cancer like ALL.

Acute lymphoblastic leukemia (ALL) is the most common hematological malignancy affecting pediatric patients. ALL treatment regimens with cytostatics manifest substantial toxicity and have reached the maximum of well-tolerated doses. One potential approach for improving treatment efficiency could be supplementation of the current regimen with naturally occurring phytochemicals with anti-cancer properties. Nutraceuticals such as quercetin, curcumin, resveratrol, and genistein have been studied in anti-cancer therapy, but their application is limited by their low bioavailability. However, their cooperative activity could potentially increase their efficiency at low, bioavailable doses. We studied their cooperative effect on the viability of a human ALL MOLT-4 cell line in vitro at the concentration considered to be in the bioavailable range in vivo. To analyze their potential side effect on the viability of non-tumor cells, we evaluated their toxicity on a normal human foreskin fibroblast cell line (BJ). In both cell lines, we also measured specific indicators of cell death, changes in cell membrane permeability (CMP), and mitochondrial membrane potential (MMP). Even at a low bioavailable concentration, genistein and curcumin decreased MOLT-4 viability, and their combination had a significant interactive effect. While resveratrol and quercetin did not affect MOLT-4 viability, together they enhanced the effect of the genistein/curcumin mix, significantly inhibiting MOLT-4 population growth in vitro. Moreover, the analyzed phytochemicals and their combinations did not affect the BJ cell line. In both cell lines, they induced a decrease in MMP and correlating CMP changes, but in non-tumor cells, both metabolic activity and cell membrane continuity were restored in time. (4) Conclusions: The results indicate that the interactive activity of analyzed phytochemicals can induce an anti-cancer effect on ALL cells without a significant effect on non-tumor cells. It implies that the application of the combinations of phytochemicals an anti-cancer treatment supplement could be worth further investigation regardless of their low bioavailability.

The burden of neoplastic diseases is widely recognized as a severe cause of mortality. The clinical inadequacy of most anticancer therapeutics urgently prompted intense drug discovery efforts toward the identification of new chemical entities endowed with a potent and safe antitumor profile. In this scenario, targeting cancer cells apoptosis machinery has emerged as a relevant strategy, useful for tackling the emergence of drug resistance. On this basis, a small library of naturally inspired hybrid molecules was obtained by combining, through a click chemistry approach, "privileged" synthons such as curcumin scaffold and 1,2,3-triazole building block.

Anticancer activity of different phenols is documented, but underlying mechanisms remain elusive. Recently, we have shown that cannabidiol kills the cells of acute lymphoblastic leukemia (ALL) by a direct interaction with mitochondria, with their consequent dysfunction. In the present study, cytotoxic effects of several phenolic compounds against human the T-ALL cell line Jurkat were tested by means of resazurin-based metabolic assay. To unravel underlying mechanisms, mitochondrial membrane potential (∆Ψ

The restricted expression of Wilms tumor 1 (WT1) and cyclin A1 (CCNA1) in normal tissues, as opposed to their abnormal expression in leukemia demonstrates the applicability of WT1 and CCNA1 as cancer antigens for immunotherapy, and as markers for prognosis and relapse. In this study, the WT1 and CCNA1 mRNA levels were found to be elevated in bone marrow samples from pediatric acute promyelocytic leukemia (APL or AML‑M3) patients, and to be quite varied in pediatric acute lymphocytic leukemia (ALL) patients, compared to non‑leukemic bone marrow controls. Consistent with the observed upregulation of both WT1 and CCNA1 in APL, WT1 overexpression elevated the CCNA1 mRNA levels in K562 leukemia cells. Treatment with curcumin decreased the WT1 levels in K562 cells, and also decreased CCNA1 protein expression. The examination of the CCNA1 promoter identified potential canonical WT1 binding sites within the 3‑kb region upstream of the transcription start site. Chromatin immunoprecipitation and luciferase reporter assays confirmed WT1 binding and the activation of the CCNA1 promoter. Furthermore, the GC‑rich core CCNA1 promoter region provided additional non‑canonical WT1 activation sites, as revealed by promoter assays. The importance of the GC‑rich core region of the CCNA1 promoter was confirmed by treating the K562 cells with mithramycin A, which blocks the binding of zinc finger transcription factors to GC‑rich sequences. Mithramycin A subsequently suppressed both CCNA1 promoter activity and protein expression in the K562 cells. Taken together, the data from the WT1 overexpression, and curcumin and mithramycin A treatment experiments, as well as those from chromatin binding assays, along with inferences from patient RNA analyses, establish a plausible link between WT1 and CCNA1, and support the functional significance of an elevated WT1 expression in leukemia, which may also affect CCNA1 expression.

Fanconi anemia (FA) is an autosomal recessive disorder with a high risk of malignancies including acute myeloid leukemia and squamous cell carcinoma. There is a constant search out of new potential therapeutic molecule to combat this disorder. In most cases, patients with FA develop haematological malignancies with acute myeloid leukemia and acute lymphoblastic leukemia. Identifying drugs which can efficiently block the pathways of both these disorders can be an ideal and novel strategy to treat FA. The curcumin, a natural compound obtained from turmeric is an interesting therapeutic molecule as it has been reported in the literature to combat both FA as well as leukemia. However, its complete mechanism is not elucidated. Herein, a systems biology approach for elucidating the therapeutic potential of curcumin against FA and leukemia is investigated by analyzing the computational molecular interactions of curcumin ligand with FANC G of FA and seven other key disease targets of leukemia. The proteins namely DOT1L, farnesyl transferase (FDPS), histone decetylase (EP3000), Polo-like kinase (PLK-2), aurora-like kinase (AUKRB), tyrosine kinase (ABL1), and retinoic acid receptor alpha (RARA) were chosen as disease targets for leukemia and modeled structure of FANC G protein as the disease target for FA. The docking investigations showed that curcumin had a very high binding affinity of -8.1 kcal/mol with FANC G protein. The key disease targets of leukemia namely tyrosine kinase (ABL1), aurora-like kinase (AUKRB), and polo-like kinase (PLK-2) showed that they had the comparable binding affinities of -9.7 k cal/mol, -8.7 k cal/mol, and -8.6 k cal/mol, respectively with curcumin. Further, the percentage similarity scores obtained from PAM50 using EMBOSS MATCHER was shown to provide a clue to understand the structural relationships to an extent and to predict the binding affinity. This investigation shows that curcumin effectively interacts with the disease targets of both FA and leukemia.

Curcumin has been documented to exert anticancer effects by interacting with altered proliferative and apoptotic pathways in cancer models. In this study, we evaluated the potential of curcumin to reverse promoter methylation of the p15 gene in Raji cells and its ability to induce apoptosis and genomic instability. Anti-neoplastic action of curcumin showed an augmentation in reactive oxygen species (ROS) and cell cycle arrest in G1 phase. Subsequently, curcumin- exposed Raji cells showed structural abnormalities in chromosomes. These observations suggest that curcumin also causes ROS-mediated apoptosis and genomic instability. The treatment of Raji cell line with 10 μM curcumin caused hypomethylation of the p15 promoter after six days. Hypomethylation of p15 was further found to be favoured by downregulation of DNA methyltransferase 1 after 10 μM curcumin treatment for six days. Methylation-specific PCR suggested demethylation of the p15 promoter. Demethylation was further validated by DNA sequencing. Reverse-transcription PCR demonstrated that treatment with curcumin (10 μM) for six days led to the up-regulation of p15 and down-regulation of DNA methyltransferase 1. Furthermore, curcumin- mediated reversal of p15 promoter methylation might be potentiated by down-regulation of DNA methyltransferase 1 expression, which was supported by cell cycle analysis. Furthermore, curcumin acts as a double-pronged agent, as it caused apoptosis and promoter hypomethylation in Raji cells.

Alterations in cell cycle regulating proteins are a key characteristic in neoplastic proliferation of lymphoblast cells in patients with Acute Lymphoblastic Leukemia (ALL). The aim of our study was to investigate whether the routinely administered ALL chemotherapeutic agents would be able to bind and inhibit the key deregulated cell cycle proteins such as--Cyclins E1, D1, D3, A1 and Cyclin Dependent Kinases (CDK) 2 and 6. We used Schrödinger Glide docking protocol to dock the chemotherapeutic drugs such as Doxorubicin and Daunorubicin and others which are not very common including Clofarabine, Nelarabine and Flavopiridol, to the crystal structures of these proteins. We observed that the drugs were able to bind and interact with cyclins E1 and A1 and CDKs 2 and 6 while their docking to cyclins D1 and D3 were not successful. This binding proved favorable to interact with the G1/S cell cycle phase proteins that were examined in this study and may lead to the interruption of the growth of leukemic cells. Our observations therefore suggest that these drugs could be explored for use as inhibitors for these cell cycle proteins. Further, we have also highlighted residues which could be important in the designing of pharmacophores against these cell cycle proteins. This is the first report in understanding the mechanism of action of the drugs targeting these cell cycle proteins in leukemia through the visualization of drug-target binding and molecular docking using computational methods.

In this study, the efficacy of orally and parenterally administered curcumin was evaluated in non‑obese diabetic/severe combined immunodeficient (NOD/SCID) mice (NOD.CB17-Prkdc(scid)/J mice) engrafted with the human t(4;11) acute lymphoblastic leukemia line, SEM. SEM cells were injected into the tail vein and engraftment was monitored by flow cytometry. Once engraftment was observed, the chemotherapeutic potential was examined by injecting mice intraperitoneally with curcumin (5 mg/kg body weight) dissolved in dimethylsulfoxide (DMSO) or DMSO alone (control) every other day, or vincristine (0.5 mg/kg body weight) 3 times per week for 4 weeks (n=16 per group). The intraperitoneal administration of curcumin did not inhibit the growth of the leukemia cells. To determine the efficacy of oral curcumin, mice were fed a control diet or a diet containing 0.5% w/w curcumin 3 weeks prior to the injection of the leukemia cells and throughout the experimental period (n=16 per group). To determine whether dietary curcumin can enhance the efficacy of a conventional chemotherapeutic agent, vincristine was injected intraperitoneally into leukemic mice fed the different diets. Dietary curcumin did not delay the engraftment or growth of leukemia cells, or sensitize the cells to vincristine. Liquid chromatography‑tandem mass spectrometry analyses of mouse sera showed that curcumin rapidly metabolized to glucuronidated and sulfated forms within 1 h post‑injection and these were the major curcumin metabolites found in the sera of the mice fed the curcumin diet. In contrast to the findings in previous in vitro models, the current data indicate that orally or parenterally administered curcumin is not a potent preventive agent against high‑risk t(4;11) acute lymphoblastic leukemia.

L-asparaginase (L-ASP) is a universal component of therapy for acute lymphoblastic leukemia (ALL). Curcumin is a naturally occurring yellow pigment that is derived from the rhizome of Curcuma longa. In this study, we evaluated the cytotoxicity of the combined treatment of L-ASP and curcumin in three ALL cell lines. Synergistic cytotoxicity was observed in all three cell lines following the combined treatment of curcumin and L-ASP. Our results revealed that curcumin significantly enhanced the antitumor effect of L-ASP in the three ALL cell lines compared to that for L-ASP alone ( p < 0.05). Curcumin and L-ASP co-treatments induced apoptosis, via activation and cleavage of caspase-8 and BID cleavage accompanied by release of cytochrome c and activation of caspase-9/3, compared to the group treated with only L-ASP and the control group. Furthermore, the combination of curcumin and L-ASP led to significant reductions in phosphorylated AKT and expression of AKT-regulated gene products (FoxO1, GSK3β, IKKα, NF-κB, XIAP) compared with the group treated with only L-ASP and the control group. Overall, our findings suggest that curcumin potentiates the antitumor effects of L-ASP in acute lymphoblastic leukemia by constitutively inhibiting AKT and AKT-regulated gene products.

Curcumin, a natural compound derived from tumeric, has been shown to induce apoptosis in the leukemic cell line K562 and other cancer cell lines. However, it is unknown whether curcumin also has an inhibitory effect on BCR-ABL-expressing B-lymphoid cells. We tested whether curcumin has an inhibitory effect on BCR-ABL B-cell acute lymphoblastic leukemia (B-ALL) in vitro and in vivo.. Pre-B cells isolated from B6 mice expressing wild-type BCR-ABL (B6p210) and T315I mutant (B6T315I) were cultured in serial concentration of curcumin. Cultured cells were analyzed by automated cell counter, flow cytometry, western blotting, and transcription factor arrays. B-ALL was induced by transplantation of MSCV-GFP-p210 transduced donor marrow in lethally irradiated Balb/c mice. Diseased mice were treated with placebo or curcumin until death of the mice. Diseased mice were analyzed by flow cytometric and histopathological analyses.. Curcumin inhibited the proliferation of B6p210 and B6T315I cells at concentration as low as 10 muM and induced apoptosis of the cells at concentrations of 30 muM. Using western blots and transcription factors arrays, we showed that curcumin decreased NF-kappaB levels and increased p53 levels. Curcumin decreased c-Abl levels in cells expressing the wild, but not the mutant, BCR-ABL oncogene. Curcumin treatment resulted in a statistically significant improved survival in diseased mice along with decreasing white blood and GFP cell counts.. Curcumin is effective against leukemic cells expressing p210 BCR-ABL and T315I BCR-ABL and holds promise in treating BCR-ABL-induced B-ALL.

When patients with cancers are treated with chemotherapeutic agents a long time, some of the cancer cells develop the multidrug resistance (MDR) phenotype. MDR cancer cells are characterized by the overexpression of multidrug resistance1(MDR1) gene which encodes P-glycoprotein (Pgp), a surface protein of tumor cells that functions to produce an excessive efflux and thereby an insufficient intracellular concentration of chemotherapeutic agents. A variety of studies have sought potent MDR modulators to decrease MDR1 gene expression in cancer cells. Our previous study has shown that curcumin exhibits characteristics of a MDR modulator in KB-V1 multidrug-resistant cells. The aim of this study was to further investigate the effect of curcumin on MDR1 gene expression in patient leukemic cells. The leukemic cells were collected from 78 childhood leukemia patients admitted at Maharaj Nakorn Chiang Mai Hospital, Chiang Mai, Thailand, in the period from July 2003 to February 2005. There were 61 cases of acute lymphoblastic leukemia (ALL), 14 cases of acute myeloblastic leukemia (AML), and 3 cases of chronic myelocytic leukemia (CML). There were 47 males and 31 females ranging from 1 to 15 years old. Bone marrows were collected. The leukemic cells were separated and cultured in the presence or absence of 10 microM curcumin for 48 hours. MDR1 mRNA levels were determined by RT-PCR. It was found that curcumin reduced MDR1 gene expression in the cells from 33 patients (42%). Curcumin affected the MDR1 gene expression in 5 of 11 relapsed cases (45%), 10 of 26 cases of drug maintenance (38%), 7 of 18 cases of completed treatment (39%), and 11 of 23 cases of new patients (48%). The expression levels of MDR1 gene in leukemic patient cells as compared to that of KB-V1 cells were classified as low level (1-20%) in 5 of 20 cases (25%), medium level (21-60%) in 14 of 32 cases (44%), and high level (61-100%) in 14 of 20 cases (70%). In summary, curcumin decreased MDR1 mRNA level in patient leukemic cells, especially in high level of MDR1 gene groups. Thus, curcumin treatment may provide a lead for clinical treatment of leukemia patients in the future.

We investigated the early events involved in loss of mitochondrial membrane potential (DeltaPsi(mt)) leading to apoptosis in cells derived from patients with acute lymphocytic leukemia after exposure to phenolic antioxidants. Using the nitric oxide binding dye diaminofluorescein-FM diacetate, we found that intracellular nitric oxide (NO) levels increased significantly within 4h after exposure to the antioxidants curcumin, carnosol, and quercetin. Inhibition of nitric oxide synthetase (NOS) activity with mercaptoethylguanidine increased the percentage of leukemia cells with depolarized mitochondria membranes after antioxidant treatment. These data suggest that NO production in the leukemia-derived cells may be a protective response to maintain DeltaPsi(mt) after antioxidant exposure and inhibition of NOS increases the disruption of mitochondrial homeostasis induced by the antioxidants.
