Methylation-associated silencing of the tissue inhibitor of metalloproteinase-3 gene suggest a suppressor role in kidney, brain, and other human cancers. (1/1745)

Tissue inhibitor of metalloproteinase-3 (TIMP-3) antagonizes matrix metalloproteinase activity and can suppress tumor growth, angiogenesis, invasion, and metastasis. Loss of TIMP-3 has been related to the acquisition of tumorigenesis. Herein, we show that TIMP-3 is silenced in association with aberrant promoter-region methylation in cell lines derived from human cancers. TIMP-3 expression was restored after 5-aza-2'deoxycytidine-mediated demethylation of the TIMP-3 proximal promoter region. Genomic bisulfite sequencing revealed that TIMP-3 silencing was related to the overall density of methylation and that discrete regions within the TIMP-3 CpG island may be important for the silencing of this gene. Aberrant methylation of TIMP-3 occurred in primary cancers of the kidney, brain, colon, breast, and lung, but not in any of 41 normal tissue samples. The most frequent TIMP-3 methylation was found in renal cancers, which originate in the tissue that normally expresses the highest TIMP-3 levels. This methylation correlated with a lack of detectable TIMP-3 protein in these tumors. Together, these data show that methylation-associated inactivation of TIMP-3 is frequent in many human tumors.  (+info)

Re-expression of endogenous p16ink4a in oral squamous cell carcinoma lines by 5-aza-2'-deoxycytidine treatment induces a senescence-like state. (2/1745)

We have previously reported that a set of oral squamous cell carcinoma lines express specifically elevated cdk6 activity. One of the cell lines, SCC4, contains a cdk6 amplification and expresses functional p16ink4a, the other cell lines express undetectable levels of p16ink4a, despite a lack of coding-region mutations. Two of the cell lines, SCC15 and SCC40 have a hypermethylated p16ink4A promoter and a third cell line, SCC9, has a mutation in the p16ink4a promoter. Using the demethylation agent 5-aza-2'-deoxycytidine, we showed that the p16ink4a protein was re-expressed after a 5-day treatment with this chemical. One cell line, SCC15 expressed high levels of p16ink4a. In this line, cdk6 activity was decreased after 5-aza-2'deoxycytidine treatment, and the hypophosphorylated, growth suppressive form of the retinoblastoma tumor suppressor protein pRB was detected. Expression of p16ink4a persisted, even after the drug was removed and the cells expressed senescence-associated beta-galactosidase activity. Ectopic expression of p16ink4a with a recombinant retrovirus in this cell line also induced a similar senescence-like phenotype. Hence, it was possible to restore a functional pRB pathway in an oral squamous cell carcinoma line by inducing re-expression of endogenous p16ink4a in response to treatment with a demethylating agent.  (+info)

5-Aza-2'-deoxycytidine is chemopreventive in a 4-(methyl-nitrosamino)-1-(3-pyridyl)-1-butanone-induced primary mouse lung tumor model. (3/1745)

Carcinogenesis is a multistep process in which many alterations in both genetic and epigenetic controls lead to a growth advantage for neoplastic cells. Hypermethylation has been established as the basis of genomic imprinting, but recent studies have also shown that alterations in genomic methylation patterns may contribute to tumorigenesis. The chemical 5-aza-2'-deoxycytidine (5-aza-dC) has been used both in vitro and in vivo to inhibit DNA methylation. In this study, we investigated the chemopreventive efficacy of 5-aza-dC in a well-established primary mouse lung tumor model. Five-week-old male (C3H/HeJ x A/J) F1 hybrid mice were treated for 24 consecutive weeks with 5-aza-dC, three times per week i.p. Lung tumors were induced with two consecutive weekly doses of 4-(methyl-nitrosamino)-1-(3-pyridyl)-1-butanone starting 1 week after initial treatment with 5-aza-dC. We demonstrated that 5-aza-dC exhibits a chemopreventive effect in this primary mouse lung tumor model which, like human lung adenocarcinomas, harbors an activating K-ras mutation. Treatment with 5-aza-dC resulted in a 23% reduction in tumor incidence, as well as a 42% reduction in tumor multiplicity. This work supports further investigation of methylation inhibitors likes 5-aza-dC for early intervention, prevention and treatment of lung cancer.  (+info)

5-azacytidine induces transgene silencing by DNA methylation in Chinese hamster cells. (4/1745)

The cytosine analog 5-azacytidine (5-AzaC) is a demethylating agent that is also known to induce mutagenesis in mammalian cells. In this study, the mutagenic potential of this drug was tested in the G10 and G12 transgenic Chinese hamster cell lines, which have a single bacterial gpt gene integrated into the genome at different sites, with its expression driven by a simian virus 40 (SV40) promoter. We show that the mutation frequencies following a 48-h exposure to different concentrations of 5-AzaC were 10 to 20 times higher than those of any of the other numerous mutagens that have been tested in the G10-G12 system. Moreover, the mutation frequencies were much higher in the G10 cell line than in the G12 cells. Detailed molecular analysis of the 6-thioguanine (6-TG)-resistant variants demonstrated that transgene silencing by de novo DNA methylation and increased chromatin condensation in the SV40 promoter was the major factor responsible for this high level of 6-TG resistance. As would be expected, exposure to 5-AzaC lowered the overall genomic DNA methylation levels, but it unexpectedly caused hypermethylation and increased chromatin condensation of the transgene in both the G10 and G12 cell lines. These results provide the first evidence that 5-AzaC may also induce transgene-specific DNA methylation, a phenomenon that can further be used for the elucidation of the mechanism that controls silencing of foreign DNA.  (+info)

Methylation of CpG in a small region of the hMLH1 promoter invariably correlates with the absence of gene expression. (5/1745)

Microsatellite instability (MSI) has been described in tumors from patients with hereditary nonpolyposis colorectal cancer, sporadic colorectal cancer, and other types of cancers. MSI is caused by the dysfunction of mismatch repairs genes. Loss of expression and mutation in one of the major mismatch repair genes, hMLH1, and the methylation of CpG sites in its promoter occur frequently in primary tumors and cell lines of colorectal cancer with MSI. To understand the mechanisms involved in the silencing of hMLH1 expression by methylation, we examined the methylation status of all CpG sites in the hMLH1 promoter in 24 colorectal cancer cell lines by the NaHSO3-sequencing method. We identified a small proximal region (-248 to -178, relative to the transcription start site) in the promoter in which the methylation status invariably correlates with the lack of hMLH1 expression. This correlation was further supported by the observation that cell lines that showed methylation-suppressed hMLH1 expression can be induced to reexpress hMLH1 by a methyl transferase inhibitor, 5-aza-2'-deoxycytidine, and the small region that we identified exhibited significant demethylation in all cell lines examined.  (+info)

A role for methylation of the hMLH1 promoter in loss of hMLH1 expression and drug resistance in ovarian cancer. (6/1745)

Experimental evidence from several sources has identified a link between mismatch repair deficiency and cytotoxic drug resistance. Selection for cisplatin resistance in the human ovarian cancer cell line A2780, results in loss of expression of the mismatch repair protein hMLH1 in most (90%) of the resultant cisplatin-resistant cell lines. Here we demonstrate that the cisplatin sensitive parental cell line displays methylation of the promoter of only one hMLH1 allele, but that the resistant cell lines all exhibit hyper-methylation of the promoters of both hMLH1 alleles. Full methylation of all sites tested was found to be invariably associated with loss of hMLH1 expression, whereas a partial increase in methylation appears compatible with either loss or maintenance of expression. In addition treatment of two of the resistant cell lines with 5-azacytidine, a known inhibitor of methylation, results in re-expression of hMLH1. Clonogenic assays demonstrate that the 5-azacytidine treated cells show increased sensitivity to cisplatin. Furthermore, 12.5% (3/ 24) of ovarian tumours show hypermethylation of the hMLH1 promoter. Expression of hMLH1 is absent in the tumours that are hypermethylated, while all the unmethylated tumours still express the protein. This analysis suggests that methylation of the hMLH1 promoter may be a common mechanism for loss of hMLH1 expression, and possibly for cisplatin-resistance, in ovarian cancer.  (+info)

Hypermethylation of the DAP-kinase CpG island is a common alteration in B-cell malignancies. (7/1745)

Death-associated protein kinase (DAP-Kinase) is a novel serine/threonine kinase whose expression is required for gamma interferon-induced apoptosis. A previous study suggested that DAP-Kinase expression may be lost epigenetically in cancer cell lines, because treatment of several nonexpressing cell lines with 5-aza-2'-deoxycytidine resulted in the expression of DAP-Kinase. Using methylation-specific polymerase chain reaction (MSP), we examined the DAP-Kinase CpG island for hypermethylation in cancer. Normal lymphocytes and lymphoblastoid cell lines are unmethylated in the 5' CpG island of DAP-Kinase. However, in primary tumor samples, all Burkitt's lymphomas and 84% of the B-cell non-Hodgkin's lymphomas were hypermethylated in the DAP-Kinase CpG island. In contrast, none of the T-cell non-Hodgkin's lymphoma samples and 15% or less of leukemia samples examined had hypermethylated DAP-Kinase alleles. U937, an unmethylated, DAP-Kinase-expressing leukemia cell line, was treated with gamma interferon and underwent apoptosis; however, Raji, a fully methylated, DAP-Kinase nonexpressing Burkitt's lymphoma cell line, only did so when treated with 5-aza-2'-deoxycytidine followed by gamma interferon. Our findings in cell lines and primary tumors suggest that hypermethylation of the DAP-Kinase gene and loss of gamma interferon-mediated apoptosis may be important in the development of B-cell malignancies and may provide a promising biomarker for B-cell-lineage lymphomas.  (+info)

Characterization of the GAGE genes that are expressed in various human cancers and in normal testis. (8/1745)

The GAGE-1 gene was identified previously as a gene that codes for an antigenic peptide, YRPRPRRY, which was presented on a human melanoma by HLA-Cw6 molecules and recognized by a clone of CTLs derived from the patient bearing the tumor. By screening a cDNA library from this melanoma, we identified five additional, closely related genes named GAGE-2-6. We report here that further screening of this library led to the identification of two more genes, GAGE-7B and -8. GAGE-1, -2, and -8 code for peptide YRPRPRRY. Using another antitumor CTL clone isolated from the same melanoma patient, we identified antigenic peptide, YYWPRPRRY, which is encoded by GAGE-3, -4, -5, -6, and -7B and which is presented by HLA-A29 molecules. Genomic cloning of GAGE-7B showed that it is composed of five exons. Sequence alignment showed that an additional exon, which is present only in the mRNA of GAGE-1, has been disrupted in gene GAGE-7B by the insertion of a long interspersed repeated element retroposon. These GAGE genes are located in the p11.2-p11.4 region of chromosome X. They are not expressed in normal tissues, except in testis, but a large proportion of tumors of various histological origins express at least one of these genes. Treatment of normal and tumor cultured cells with a demethylating agent, azadeoxycytidine, resulted in the transcriptional activation of GAGE genes, suggesting that their expression in tumors results from a demethylation process.  (+info)

In this research study, the study drug SL-401 will be combined with the standard dose of azacitidine (for MDS patients) or azacitidine/venetoclax (for AML patients). The goal of this research study is to try and determine the safest, highest dose of study drug, SL-401, in combination with azacitidine or azacitidine/venetoclax that can be given to patients with AML or high-risk MDS. SL-401 works by stopping or slowing the growth of cancer stem cells, which are ...
Currently patients with resectable (can be removed by surgery) esophageal cancer will receive chemotherapy before surgery to try to shrink the tumor before it is removed. This study will evaluate whether giving azacitidine before each cycle of chemotherapy to increase the shrinkage of the tumor prior to surgery is safe.. Azacitidine is currently approved by the Food and Drug Administration (FDA) for treatment of myelodysplastic syndrome (MDS). Azacitidine is not approved by the FDA for use in this study and is therefore considered investigational. Because azacitidine has not been given before in combination with epirubicin, oxaliplatin and capecitabine, we will also evaluate the safety and tolerability of azacitidine and find out what dose of azacitidine is safe to give with this chemotherapy. ...

Treatment with the demethylating agent 5-Azacytidine leads to prolonged survival for patients with myelodysplastic syndrome, and the demethylation induces upregulation of cancer-testis antigens. Cancer-testis antigens are well-known targets for immune recognition in cancer, and the immune system may have a role in this treatment regimen. We show here that 5-Azacytidine treatment leads to increased T-cell recognition of tumor cells. T-cell responses against a large panel of cancer-testis antigens were detected before treatment, and these responses were further induced upon initiation of treatment. These characteristics point to an ideal combination of 5-Azacytidine and immune therapy to preferentially boost T-cell responses against cancer-testis antigens. To initiate such combination therapy, essential knowledge is required about the general immune modulatory effect of 5-Azacytidine. We therefore examined potential treatment effects on both immune stimulatory (CD8 and CD4 T cells and Natural ...
SGI-110, is a novel second generation DNA hypomethylating agent, which shows promising single agent activity in leukaemia patients (NCT01261312) and is currently under investigation as a priming agent in solid tumors. There is evidence that the acquisition of platinum resistance in ovarian cancer is associated with DNA methylation changes that result in epigenetic silencing of specific genes. Pre-clinical studies suggest that DNA hypomethylating agents can reverse such resistance. SGI-110 is currently in a Phase II clinical trial in combination with carboplatin, in platinum-resistant recurrent ovarian cancer patients (NCT01696032). SGI-110 is a dinucleotide of decitabine and deoxyguanosine, which is resistant to modification by cytidine deaminase: a common pathway of decitabine metabolism and deactivation.. We demonstrated that SGI-110 conferred global LINE1 de-methylation and re-expression of epigenetically silenced genes in a panel of ovarian cancer cell lines. We identified three cell lines, ...

Growing evidence indicates that aberrant DNA hypermethylation is associated with leukemogenesis, chemotherapy resistance, and relapse. DNA methyltransferase inhibitors such as azacitidine and decitabine have been shown to reverse drug resistance and prime leukemia cells to cytotoxic agents in vitro. Here we report the first pediatric phase 1 study using azacitidine in sequence with chemotherapy in patients with relapsed/refractory leukemia. Fourteen patients were enrolled, twelve with acute myeloid leukemia (AML) and two with acute lymphoblastic leukemia (ALL). All patients received azacitidine 75mg/m2/day subcutaneously for 5 days, followed by fludarabine 30mg/m2/day and cytarabine 2gm/m2/day intravenously for 5 days. The median number of prior regimens was 2 (range 1-5). Toxicities were typical of intensive chemotherapy. Febrile neutropenia and infection were the most common non-hematologic toxicities. No patients experienced dose-limiting toxicity. Seven of twelve AML patients achieved ...

Histone deacetylase (HDAC) inhibitors either alone or in combination with hypomethylating agents have limited clinical effect in acute myeloid leukemia (AML). Previously, we demonstrated that AML patients with higher miR (microRNA)-29b expression had better response to the hypomethylating agent decitabine. Therefore, an increase in miR-29b expression preceding decitabine treatment may provide a therapeutic advantage. We previously showed that miR-29b expression is suppressed by a repressor complex that includes HDACs. Thus, HDAC inhibition may increase miR-29b expression. We hypothesized that priming AML cells with the novel HDAC inhibitor (HDACI) AR-42 would result in increased response to decitabine treatment via upregulation of miR-29b. Here, we show that AR-42 is a potent HDACI in AML, increasing miR-29b levels and leading to downregulation of known miR-29b targets (that is, SP1, DNMT1, DNMT3A and DNMT3B). We then demonstrated that the sequential administration of AR-42 followed by decitabine

A fission yeast gene which shares considerable sequence homology with cytosine-specific DNA methyltransferases has recently been identified. This discovery has led us to investigate the effects of the treatment of fission yeast with the nucleoside analogue 5-azacytidine (5-azaC). 5-AzaC is known to inhibit cytosine methylation as a result of the formation of stable covalent complexes between DNA (cytosine-5) methyltransferases (C5 Mtases) and 5-azaC containing DNA. Here we demonstrate that 5-azaC treatment of Schizosaccharomyces pombe leads to reversible cell cycle arrest at the G2/M transition. This reversible arrest is dependent on the cell cycle checkpoint mechanisms which act to prevent the onset of mitosis in the presence of either damaged or unreplicated DNA. Treatment of S. pombe cell division cycle and checkpoint mutants indicates that 5-azaC causes DNA damage and is likely to inhibit a late stage in DNA replication. The data show that viability in the presence of the drug requires both ...

If the synergy we observe in vivo in the A2780/cp70 xenograft is not related to MLH1 re-expression but to some other interaction between DAC and the cytotoxic drug, then it might be expected that synergy would also be observed in xenografts of A2780/cp70 that have hMLH1 reintroduced by chromosome 3 transfer. Indeed, there is a small but significant increase in sensitivity of CP70-ch3 to cisplatin (Fig. 4G ⇓ and Table 1 ⇓ ; P , 0.01), but this is a very small effect compared with the sensitization observed in A2780/cp70. DAC did not sensitize MMR-proficient CP70-ch3 xenografts to the other three cytotoxic drugs examined, carboplatin, temozolomide, and epirubicin (Table 1) ⇓ . This suggests that the small sensitization that we observe for cisplatin is attributable to a specific interaction between these two agents, which may be related to the synergy reported in cell lines in vitro (23) . A2780/cp70 and CP70-ch3 xenografts are equally sensitive to Taxol (15 mg/kg i.v.), and DAC has no effect ...

Therapy for acute myeloid leukemia (AML) in elderly populations (,65 years) is still a challenge for scientists and hematologists worldwide, and represents an urgent medical need. Notably, the identification and the recognition of molecular and epigenetic mechanisms involved in the pathogenesis of such a heterogeneous disease, are providing new tools for a more successful and targeted approach. Azacitidine is a hypomethylating agent (HMA) with relevant activity in patients affected by myelodysplastic syndrome (MDS) and AML with low blast cells percentage (,30%), in terms of reduction of transfusion dependence, and improvement of quality of life ...

The cytidine analogues 5-azacytidine and decitabine have a powerful molecular epigenetic effect: depletion of DNA-methyltransferase. This is an S-phase, DNA-replication dependent action, so treatment exposure time is likely a crucial determinant of efficacy, and genetic factors that influence cytidine analogue metabolism could potentially affect treatment outcomes. The ubiquitously expressed enzyme cytidine deaminase (CDA) rapidly inactivates 5-azacytidine/decitabine. Mahfouz and colleagues evaluated here for the first time the impact of pharmacogenetic factors that affect CDA enzyme activity/expression on 5-azacytidine/decitabine treatment outcomes. Interestingly and significantly, they found that gender had a substantially greater influence on CDA enzyme activity/expression than the well-known CDA SNP A79C, with a corresponding impact on overall survival in 5-azacytidine/decitabine-treated MDS patients. The identification of this pharmacogenetic factor and the mechanism by which it affects ...

Patients whose lymphomas recur after initial chemotherapy are treated with a combination of approaches, including high-dose chemotherapy followed by a stem cell transplant. However, some patients have tumors that do not respond to these extensive second treatments, and many of these patients die within two years of diagnosis.. When lymphomas are formed, they shut down the cellular programs that sense that something is wrong in the cells. Once these fail-safe mechanisms that trigger cell death are shut down, it becomes difficult to kill the tumor with chemotherapy, said Leandro Cerchietti, M.D., assistant professor at the Hematology and Oncology Division of Weill Cornell Medical College in New York. Our study showed that using low concentrations of the DNA methyltransferase inhibitors decitabine or azacitidine, these fail-safe mechanisms can slowly be awakened to induce lymphoma cell death when chemotherapy is administered.. Cerchietti and colleagues conducted a phase I trial in patients with ...

5-Azacytidine is a well-established nucleoside analog for the treatment of MDS and AML. These diseases are characterized by an overproliferation of poorly differentiated myeloid progenitor cells (Griffiths and Gore, 2013). Clinical resistance to 5-azacytidine is common, with more than half of all MDS/AML patients not responding to 5-azacytidine treatment, which ultimately leads to poor treatment outcome (Issa, 2007). An understanding of the resistance mechanisms to 5-azacytidine is hampered by the incomplete knowledge of the mode of action of this drug. Although the central cellular effects of 5-azacytidine are cytotoxicity as well as DNA and RNA demethylation (Rius and Lyko, 2012), the determinants that cause the chemoresistance to 5-azacytidine are unknown.. The expression of transporters has been closely linked to drug resistance, and therefore they represent important candidate biomarkers during chemotherapy (Gillet and Gottesman, 2010; Shaffer et al., 2012). Efflux transporters such as ...
This Phase 1/2 study will evaluate the safety, efficacy, PK, and PD of FT-2102 (olutasidenib) as a single agent or in combination with azacitidine or cytarabine. The Phase 1 stage of the study is split into 2 distinct parts: a dose escalation part, which will utilize an open-label design of FT-2102 (olutasidenib) (single agent) and FT-2102 (olutasidenib) + azacitidine (combination agent) administered via one or more intermittent dosing schedules followed by a dose expansion part. The dose expansion part will enroll patients in up to 5 expansion cohorts, exploring single-agent FT-2102 (olutasidenib) activity as well as combination activity with azacitidine or cytarabine. Following the completion of the relevant Phase 1 cohorts, Phase 2 will begin enrollment. Patients will be enrolled across 8 different cohorts, examining the effect of FT-2102 (olutasidenib) (as a single agent) and FT-2102 (olutasidenib) + azacitidine (combination) on various AML/MDS disease states.. ...

118 medications are known to interact with azacitidine. Includes Aredia (pamidronate), Ativan (lorazepam), Co-trimoxazole (sulfamethoxazole/trimethoprim).
Pregnant Wistar rats were injected i.p. with 5-azacytidine (5AzC) at 11 day of gestation. Brain cell apoptosis determined morphologically or by TUNEL method was observed in the fetuses 3 hrs after injection. Eight to 100% of the fetuses were dead at 1 to7 day after injection. Injection with doses less than 5 mg/kg of 5AzC killed only a few fetuses, though neuronal apoptosis was detected in most of living fetuses. All fetuses were dead when their dams were injected with 5AzC at 9 or 10 day of gestation, whereas most of the fetuses were alive when injected after day 12. The present study revealed that 5AzC specifically induce neuronal apoptosis in rat fetuses at the stage of logarithmic growth.. ...
A key characteristic of cancer cells is the presence of genome alterations, including changes in epigenetic modifications that can profoundly impact gene expression and cellular function. Regulators of DNA methylation and histone modification can thus be considered as potential therapeutic targets in oncology. In recent years, DNA methyltransferase inhibitors and histone deacetylase inhibitors have shown efficacy in treating some hematological malignancies. Intense efforts are underway to develop the next generation of inhibitors, including targeting additional epigenetic regulators, and further to test treatment of solid tumors. The reviews in this series explore advances in cancer epigenetics driven by high-throughput sequencing studies, the clinical use of DNA methyltransferase inhibitors, the development of inhibitors targeting histone modifying enzymes, biomarkers of drug efficacy, and aging-related changes in the epigenome. In his overview, series editor Peter Jones highlights ongoing ...

Pertussis is a contagious highly, acute respiratory disease due to the bacterial pathogen strains and evaluated pets for clinical disease. USA this year 2010, the best number STAT91 because the 1950s, pertussis may be the most common from the vaccine-preventable illnesses (2). This resurgence is certainly mirrored through the entire industrial globe, despite equivalent high prices of vaccination (12, 20, 31). Many hypotheses have already been recommended for the upsurge in instances, but there is no consensus within the medical community (9). Our failure to comprehend and counteract this important public health concern is due in large part to gaps in our knowledge of the disease and the mechanisms of vaccine-mediated safety. In order to fill these gaps, a good animal model of pertussis is required. In humans, infection with results in a wide spectrum of medical manifestations that depends on the age and immune status of the sponsor and ranges from slight respiratory symptoms to a severe cough ...
Alzheimers disease (AD) is among the most serious human being medical and socioeconomic burdens. Neurochemical methods included testing of the NR1/NR2A/NR2B subunits of NMDA receptors in the frontal cortex and CHT1 transporters in the hippocampus in both instances in the right and remaining hemisphere separately. Our results display that Samaritan rats? show noticeable impairment in both the MWM and active place avoidance jobs suggesting a deficit of spatial learning and memory space. Moreover Samaritan rats exhibited significant CP-673451 changes in NR2A manifestation and CHT1 activity compared to settings rats mimicking the situation in individuals with early stage AD. Taken collectively our results corroborate the hypothesis that Samaritan rats are a encouraging model of AD in its early stages. studies since the living human brain is definitely barely accessible to biochemical exam. You will find two basic forms of AD: familial and sporadic. The familial form is very rare and is related to ...
DNA methyltransferases (DNMTs) are epigenetic enzymes involved in embryonic development, cell differentiation, epithelial to mesenchymal transition, and control of gene expression, whose overexpression or enhanced catalytic activity has been widely reported in cancer initiation and progression. To date, two DNMT inhibitors (DNMTi), 5-azacytidine (5-AZA) and 5-aza-2′-deoxycytidine (DAC), are approved for the treatment of myelodysplastic syndromes and acute myeloid leukemia. Nevertheless, they are chemically instable and quite toxic for healthy cells; thus, the discovery of novel DNMTi is urgent. Here, we report the identification of a new quinoline-based molecule, MC3353, as a non-nucleoside inhibitor and downregulator of DNMT. This compound was able, in promoter demethylating assays, to induce enhanced green fluorescence protein (EGFP) gene expression in HCT116 cells and transcription in a cytomegalovirus (CMV) promoter-driven luciferase reporter system in KG-1 cells. Moreover, MC3353 displayed a
The goal of this clinical research study is to find the highest tolerable dose of ABT-348 that can be given alone or with Vidaza (azacitidine) to patients with either leukemia or MDS. The safety of this drug or drug combination will also be studied. ABT-348 is designed to block proteins that cause cancer cells to grow and multiply. ABT-348 is also designed to block the formation of new blood vessels for the tumor. This may cause the cancer cells to die. This is the first study using ABT-348 in humans. Azacitidine is designed to block certain proteins in cancer cells whose job is to stop the function of the tumor-fighting proteins. By blocking these proteins, the tumor-fighting genes may be able to work better.
Azacitidine is the first agent to significantly prolong overall survival (OS) compared with conventional care regimens in patients with higher-risk myelodysplastic syndromes (MDS). Here, we review currently available data on azacitidine treatment in lower-risk MDS. In a phase III study, a subset of patients with lower-risk MDS treated with azacitidine achieved an overall response rate (ORR) of 60% and a longer median OS compared with supportive care (44 vs 27 months). In a phase II study investigating various azacitidine dose schedules, the
The proportion of attributable deaths varied according to a patients MDS risk status. The proportion of deaths attributable to MDS increased from 31.5% among low-risk patients to 48.8% in the intermediate-risk category and 74.1% of patients with high-risk MDS. CAD/stroke as the cause of death decreased from a high of 26.3% of patients with low-risk disease to 20.6% of patients with intermediate risk-MDS to 9.3% of patients with high-risk MDS.. Treatment of Myelodysplastic Syndrome. Lower-risk myelodysplastic syndrome patients are treated initially for the specific complications of the disease, such as anemia and low blood counts. If more aggressive therapy is needed, strategies that are considered standard of care include chemotherapy using hypomethylating agents (5-azacitidine and decitabine) and lenalidomide.. Higher-risk myelodysplastic syndrome patients usually need more aggressive therapy, but much depends on the age and condition of the patient. Younger patients with high-risk disease are ...

Compared with World Health Organization-defined acute myeloid leukaemia (AML) not otherwise specified, patients with AML with myelodysplasia-related changes (AML-MRC) are generally older and more likely to have poor-risk cytogenetics, leading to poor response and prognosis. More than one-half of all older (≥65 years) patients in the phase 3 AZA-AML-001 trial had newly diagnosed AML-MRC. We compared clinical outcomes for patients with AML-MRC treated with azacitidine or conventional care regimens (CCR; induction chemotherapy, low-dose cytarabine, or supportive care only) overall and within patient subgroups defined by cytogenetic risk (intermediate or poor) and age (65-74 years or ≥75 years). The same analyses were used to compare azacitidine with low-dose cytarabine in patients who had been preselected to low-dose cytarabine before they were randomized to receive azacitidine or CCR (ie, low-dose cytarabine). Median overall survival was significantly prolonged with azacitidine (n = 129) versus CCR (n
Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematopoietic stem cell disorders that have a substantial impact on patients quality of life, in addition to causing significant morbidity and mortality. The hypomethylating agents (HMAs) azacitidine and decitabine are approved for use in the United States and in Europe for the treatment of MDS or acute myeloid leukemia (AML) and, in the case of azacitidine, prolong survival in higher-risk patients.
The spin-trap free radical scavenger N-tert-butyl-a-phenylnitron (PBN) ameliorated effects of several teratogens involving reactive oxygen species (ROS). We investigated for the first time whether PBN could ameliorate teratogenesis induced by a DNA hypomethylating hematological therapeutic 5-azacytidine (5azaC). At days 12 and 13 of gestation, Fisher rat dams were pretreated by an i.v. injection of PBN (40mg/kg) and 1 h later by an i.p. injection of 5azaC (5mg/kg). Development was analyzed at gestation day 15 in embryos and day 20 in fetuses. PBN alone did not significantly affect development. PBN pretreatment restored survival of 5azaC-treated dams embryos to the control level, restored weight of embryos and partially of fetuses, and partially restored crownrump lengths. PBN pretreatment converted limb adactyly to less severe oligodactyly. PBN pretreatment restored global DNA methylation level in the limb buds to the control level. Cell proliferation in limb buds of all 5azaCtreated dams ...
Azacytidine is an inhibitor of DNA methyltransferase and is known to be an anti-leukemic agent to induce cancer cell apoptosis. In the present study, multiple myeloma cells were treated with azacytidine at clinically relevant concentrations to induce necrosis through oxidative stress. Necrotic myeloma cells exhibit unique characteristics, including enrichment of the cell-bound albumin and overexpression of endoplasmic reticulum (ER)- and mitochondrial-specific chaperones, which were not observed in other necrotic cells, including HUH-7, A2780, A549, and Hoc1a. Proteomic analysis shows that HSP60 is the most abundant up-regulated mitochondrial specific chaperone, and azacytidine-induced overexpression of HSP60 is confirmed by western blot analysis. In contrast, expression levels of cytosolic chaperones such as HSP90 and HSP71 were down-regulated in azacytidine-treated myeloma cells, concomitant with an increase of these chaperones in the cell culture medium, suggesting that mitochondrial chaperones and
The role of neurotrophic factors (NTFs) in neuronal development, differentiation, neuroprotection, and maintenance is well documented. The novel family of mesencephalic astrocyte-derived neurotrophic factor (MANF) and cerebral dopamine neurotrophic factor (CDNF) have been found to protect dopaminergic neurons, providing a potential therapeutic avenue for neurodegenerative diseases. Our group has previously shown an induction of NTFs including MANF and CDNF, following treatment with valproic acid (VPA), a histone deacetylase (HDAC) inhibitor, in both cultured cells and rat brain. Furthermore, increased histone H3 acetylation was observed, indicating that epigenetic mechanisms may play a role in the modulation of MANF and CDNF. The interaction between HDAC inhibitors and DNA demethylation prompted us to investigate if DNA demethylation plays a role in the regulation of these NTFs. Treatment with 5-azacytidine (AZA; 1 - 25 µM), a potent DNA demethylating agent, for 24 hours, resulted in a ...

Aberrant DNA methylation is a common feature of cancer, which has been targeted for pharmacologic intervention because of its reversible nature. Nucleoside analogs such as 5-azacytidine, 5-aza-2-deoxycytidine, and zebularine are mechanism-based inhibitors of DNA methylation that are incorporated into the DNA during replication and deplete the DNA methyltransferase enzymes. 5-Azacytidine and 5-aza-2-deoxycytidine are extremely potent inhibitors and may be ideal for use in chemotherapy of cancer. Delivery of these inhibitors has been facilitated with the use of short oligonucleotides that prevent enzymatic degradation. On the other hand, zebularine, a more stable and less toxic surrogate of the other two compounds may be best utilized as a chemopreventive agent. Chronic oral administration of zebularine in a murine colon cancer model highlighted its low toxicity and gender- and tissue-specific action against DNA methylation ...

N2 - Short-chain fatty acids, metabolites produced by colonic microbiota from fermentation of dietary fiber, act as anti-inflammatory agents in the intestinal tract to suppress proinflammatory diseases. GPR109A is the receptor for short-chain fatty acids. The functions of GPR109A have been the subject of extensive studies; however, the molecular mechanisms underlying GPR109A expression is largely unknown. We show that GPR109A is highly expressed in normal human colon tissues, but is silenced in human colon carcinoma cells. ...
During the past decade, intense effort has been focused on the development of specific FXS treatments that might lead to eventual cure. Two possible approaches are presently being considered for a substantial treatment of FXS: (a) reactivation of the affected gene and (b) compensating for the lack of FMRP.. Epigenetic modulators. The strategy of restoring FMR1 gene activity, which is based on the presence of the intact FMR1 coding sequence, targets potentially reversible epigenetic changes, primarily DNA methylation. The first compound tested on cells derived from patients with FXS was the drug 5-aza-deoxycytidine (5-azadC, a methyltransferase inhibitor; Figure 3A), which restored transcription and translation of the FMR1 gene (95). Furthermore, treatment with histone deacetylase inhibitors (TSA, butyrate, and 4-phenylbutyrate) potentiated the effect of 5-azadC (96). Reactivation was accompanied not only by DNA demethylation but also by changes in the epigenetic code of histones H3 and H4 (97). ...
Bae et al. [6] suggest that three dimensional (3D) culture system could promote the osteogenic and adipogenic differentiation potential of bone-marrow derived mouse MSCs, and additional treatment of azacitidine (AZA), a DNA methyltransferase inhibitor, could further enhance the osteogenic differentiation ability. However, other progenitor properties, including proliferation and colony-forming efficiency were not significantly affected by either treatment compared to conventionally cultured MSCs.. Bone-marrow derived MSCs reside within a complex environment in which MSCs are subjected to various mechanical stimuli of the bone and also environmental stimuli from interacting cell types. However, classic two dimensional (2D) cultures lack these mechanical stimuli and vital cues by hematopoietic cells and nonadherent population of mesenchymal progenitors. Therefore, to preserve MSC progenitor potency, studies have focused on expansion techniques to recreate an elaborate bone marrow niche through 3D ...
IWG) criteria. With a median duration of follow-up of 10.8 months, the median duration of response was 8.4 months and the median duration of CR was 7.3 months. Seventeen (52%) evaluable MDS patients discontinued therapy to pursue stem cell transplant. Median overall survival (OS) for all enrolled patients (n=55) was 10.8 months. Median OS in responding patients versus non-responders was 13.7 vs. 3.9 months. Adverse events, regardless of causality, were mostly grade 1/2. Grade 3+ adverse events occurring in ≥20% of patients were limited to cytopenias and infection, consistent with underlying hematopoietic malignancies, and no exacerbation of the expected AZA-related safety profile has been observed.. About the Clinical Trial. Eligible patients in the Phase Ib/II clinical trial include HMA-naïve, TP53 mutated MDS, oligoblastic acute myeloid leukemia (AML, ≤ 30% blasts), MDS-myeloproliferative neoplasm (MDS-MPN) overlap and chronic myelomonocytic leukemia (CMML).

Promoter hypermethylation of genes important in the regulation of cell proliferation and differentiation is a frequent abnormality observed in primary neoplasms and tumor cell lines (40 , 41) . Thus, the application of pharmacologic inhibitors of DNA methylation provides an attractive and rational approach to re-establish the antiproliferative and differentiation-inducing signals silenced by hypermethylation (42) . However, the preliminary results of studies with methylation inhibitors in the clinical trials were not encouraging. Initial trials of 5-azacytidine in patients with sickle cell disease and β-thalassemia (43 , 44) were abandoned because of an apparent increase in the incidence of tumors in rats treated with this agent (45) . In 1988, a novel methylation inhibitor DAC was reported to be nontumorigenic and was shown to demonstrate antitumor effects in animal models (46) . Moreover, studies of methylation inhibitors in patients with myelodysplastic syndrome and acute myeloid leukemia ...

By 2018, five new drugs will have been launched for the treatment of myelodysplastic syndromes (MDS), three of which are expected to offer much-needed second-line therapeutic options in the hypomethylating agent (HMA)-refractory higher-risk MDS population, according to a new study. - News - PharmaTimes
Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematopoietic neoplasms, manifesting with dysplastic bone marrow failure, peripheral blood cytopenias and variable predisposition for transformation to acute myeloid leukemia (AML). Diagnosis is heavily reliant on non-specific, subjective morphology, particularly in early stages - karyotype results are most often normal, and no MDS-specific molecular assays currently exist. Diagnosis is often delayed, requiring serial invasive bone marrow investigations. Moreover, MDS primarily afflicts older adults and, without molecular targets and assays, treatments are mainly supportive (i.e. blood transfusions and growth factors). While some MDS patients respond to emerging agents, such as hypomethylating agents, it is not entirely clear how to predict treatment responses. With our aging demographics, MDS prevalence is expected to increase, along with demands for novel and more personalized treatment. Recurring MDS-associated somatic ...
