The added value of 2nd generation tyrosine kinase inhibitors (TKIs) is currently perhaps the most-discussed issue in chronic myeloid leukemia (CML) research and treatment. Therefore, with their recently published article "Second-generation tyrosine kinase inhibitors improve the survival of patients with chronic myeloid leukemia in whom imatinib therapy has failed", Ibrahim et al.1 focussed on an important topic. However, in our opinion, the methodological approach used in this paper is not always appropriate.. The choice of the historical control group treated with interferon-alfa seems not to be optimal. Even before the imatinib era, progress had been made in the treatment of CML as the results of the consecutive German studies and of the French CML-study group show.2-4 We doubt that the results of the 20-year old MRC trial represent an appropriate comparator group for the results achieved by the use of 2nd generation tyrosine kinase inhibitors. Furthermore, the authors use two different ...

TY - JOUR. T1 - Tyrosine kinase inhibitor therapy can cure chronic myeloid leukemia without hitting leukemic stem cells. AU - Lenaerts, Tom. AU - Pacheco, Jorge M.. AU - Traulsen, Arne. AU - Dingli, David M. PY - 2010/6. Y1 - 2010/6. N2 - Background: Tyrosine kinase inhibitors, such as imatinib, are not considered curative for chronic myeloid leukemia - regardless of the significant reduction of disease burden during treatment - since they do not affect the leukemic stem cells. However, the stochastic nature of hematopoiesis and recent clinical observations suggest that this view must be revisited. Design and Methods: We studied the natural history of a large cohort of virtual patients with chronic myeloid leukemia under tyrosine kinase inhibitor therapy using a computational model of hematopoiesis and chronic myeloid leukemia that takes into account stochastic dynamics within the hematopoietic stem and early progenitor cell pool. Results: We found that in the overwhelming majority of patients ...

Title: Interferon alpha for Treatment of Chronic Myeloid Leukemia. VOLUME: 12 ISSUE: 3. Author(s):Bengt Simonsson, Henrik Hjorth-Hansen, Ole Weis Bjerrum and Kimmo Porkka. Affiliation:Department of Hematology 50C, Uppsala University Hospital, Uppsala, 75185 Sweden.. Keywords:Interferon-alpha, chronic myeloid leukemia, imatinib, combination therapy, chronic myeloid leukemia stem cells, BCR, BCR-ABL1, CML cell, fluorescent in situ hybridization, allogeneic stem cell transplantation, allogeneic SCT, poietic stern cells, leukemic effect in CML, psychosis, autoimmune disorders, thyreoiditis. Abstract: Treatment of chronic myeloid leukemia (CML) with interferon-alpha (IFN-α) was introduced in the early 1980s. Several clinical trials showed a survival advantage for patients treated with IFN-α compared to conventional chemotherapy. Some patients achieved longstanding complete cytogenetic remissions (i.e. > 2 log tumor mass reduction). IFN-α was then recommended as first line medical treatment until ...
We have followed one patient with Philadelphia (Ph)-negative chronic myelogenous leukemia and identified an additional four patients from the literature who showed the rearrangement in the breakpoint cluster region (bcr) on chromosome 22 characteristic of Ph-positive chronic myelogenous leukemia. The clinical course of these five patients was similar to that of Ph-positive patients, with easily controlled leukocyte counts, a prolonged benign phase, and prolonged survival. Furthermore, we have shown, for the first time, that bcr rearrangement in Ph-negative chronic myelogenous leukemia can result in expression of the aberrant 210-kilodalton bcr-abl fusion protein, which has been strongly implicated in Ph-positive leukemogenesis. Research data pertaining to possible cytogenetic mechanisms leading to production of p210bcr-abl in the absence of the Ph chromosome are reviewed. Molecular analysis provides an important tool for classifying and predicting prognosis of some patients with Ph-negative ...
The BCR-ABL1 oncoprotein is found in a subset of patients with ALL carrying the Philadelphia chromosome. This translocation is the most common cytogenetic abnormality in adults, with ALL occurring in 25% of patients (33). BCR-ABL1 defines a high-risk group and, as such, patients receive intensive chemotherapy in combination with ABL TKIs and are considered for hematopoietic stem cell transplantation (HSCT). Despite the great success with combination of high-dose ABL TKIs and intensive chemotherapy, there are still drawbacks that need to be addressed. Above all, 40% of patients, even with HSCT, have relapse of the disease. Furthermore, it is not clear whether responsive patients without HSCT cannot have relapse of the disease, as there is evidence that BCR-ABL1-positive leukemia stem cells remain present in the patients bone marrow even after years of therapy. Therefore, it is necessary to define targets in BCR-ABL1-positive leukemia stem cells that may be candidates for new treatment ...

Recent improvements in cell purification and transplantation techniques have contributed to the identification of cell populations known as tumor-initiating cells (TIC). This discovery has led to the cancer stem cell hierarchy concept, which holds that tumors are organized as a hierarchy of malignant tissues sustained by such TIC. However, this concept remains controversial. In this review, we examine recent advances in cancer stem cell research that have been generated from studies of Philadelphia (Ph) chromosome-positive leukemia. The abnormal Ph chromosome, which arises from a translocation creating the BCR-ABL1 fusion gene, is most commonly associated with chronic myelogenous leukemia (CML) and precursor B cell acute lymphoblastic leukemia (B-ALL). Examination of the pathophysiology of these diseases has provided interesting insights into not only the hierarchy of leukemia stem cells but also their clonal evolution. Both shared and unique regulatory mechanisms affecting normal and CML stem ...
Tyrosine kinase inhibitors (TKIs) induce molecular remission in the majority of patients with chronic myelogenous leukemia (CML), but the persistence of CML stem cells hinders cure and necessitates indefinite TKI therapy. We report that CML stem cells upregulate the expression of pleiotrophin (PTN) and require cell-autonomous PTN signaling for CML pathogenesis in BCR/ABL+ mice. Constitutive PTN deletion substantially reduced the numbers of CML stem cells capable of initiating CML in vivo. Hematopoietic cell-specific deletion of PTN suppressed CML development in BCR/ABL+ mice, suggesting that cell-autonomous PTN signaling was necessary for CML disease evolution. Mechanistically, PTN promoted CML stem cell survival and TKI resistance via induction of Jun and the unfolded protein response. Human CML cells were also dependent on cell-autonomous PTN signaling, and anti-PTN antibody suppressed human CML colony formation and CML repopulation in vivo. Our results suggest that targeted inhibition of PTN ...
The FDA has approved bosutinib (Bosulif) to treat chronic myelogenous leukemia (CML). The drug is intended for patients with chronic, accelerated, or blast phase Philadelphia chromosome-positive CML who are resistant to or who cannot tolerate other therapies, including imatinib (Gleevec).. The safety and effectiveness of Bosulif was evaluated in a single clinical trial that enrolled 546 adult patients with chronic, accelerated, or blast phase CML. All patients had disease that progressed after treatment with imatinib or imatinib followed by dasatinib (Sprycel) and/or nilotinib (Tasigna), or who could not tolerate the side effects of prior therapy.. Results showed 34% of patients with chronic phase CML who had been previously treated with imatinib achieved a major cytogenetic response after 24 weeks. Of the patients who achieved a major cytogenetic response at any time, 52.8% had their response last at least 18 months. Among patients previously treated with imatinib followed by dasatinib and/or ...

The graft-versus-leukemia (GVL) effect in allogeneic hematopoietic stem cell transplantation (alloSCT) is potent against chronic phase chronic myelogenous leukemia (CP-CML), but blast crisis CML (BC-CML) and acute myeloid leukemias (AML) are GVL resistant. To understand GVL resistance, we studied GVL against mouse models of CP-CML, BC-CML, and AML generated by the transduction of mouse BM with fusion cDNAs derived from human leukemias. Prior work has shown that CD4+ T cell-mediated GVL against CP-CML and BC-CML required intact leukemia MHCII; however, stem cells from both leukemias were MHCII negative. Here, we show that CP-CML, BC-CML, and AML stem cells upregulate MHCII in alloSCT recipients. Using gene-deficient leukemias, we determined that BC-CML and AML MHC upregulation required IFN-γ stimulation, whereas CP-CML MHC upregulation was independent of both the IFN-γ receptor (IFN-γR) and the IFN-γ/γ receptor IFNAR1. Importantly, IFN-γR-deficient BC-CML and AML were completely resistant ...

In this retrospective analysis, fourteen/18 (78%) evaluable patients were found challenged with higher doses of IM (600-800 mg/day), with one return to CP and one transient CCyR after IM combined with chemotherapy, and 12 failures. Six patients (1 CP, 5 BC) were treated with dasatinib, and no difference in survival was seen between dasatinib-treated and non-treated patients (p=0.15). None of the patients received nilotinib. Additionally, 3 patients underwent allogeneic stem cell transplantation with 2 remaining alive at 1 and 14 months follow-up. Finally, at latest follow-up, overall survival since IM initiation (Figure 1B), however longer for CP (42.5 Mo.) was not statistically different than that for AP+BC (17.5 Mo., p=0.08) patients.. The onset of BCR-ABLT315I mutations during the treatment of CML with TKIs remains challenging, because this mutation is the most frequently identified in IM-treated patients6, and none of the TKIs clinically available to date4,5,6 retain any activity in vitro. ...

TY - CHAP. T1 - Targeted Therapies in Chronic Myeloid Leukemia. AU - Jabbour, Elias. AU - Cortes, Jorge. PY - 2015/10/30. Y1 - 2015/10/30. N2 - Until 2000, therapy for chronic myeloid leukemia (CML) was limited to nonspecific agents such as busulfan, hydroxyurea, and interferon-alpha (IFN-a). The landscape changed dramatically with the development of small-molecule tyrosine kinase inhibitors (TKIs) that was shown to potently interfere with the interaction between the BCR-ABL protein and adenosine triphosphate (ATP), blocking cellular proliferation of the malignant clone. Three TKIs are commercially available for the front-line treatment of CML: imatinib, dasatinib, and nilotinib. With the updates of the DASISION and ENESTnd trials, the question often arises as to the optimal choice for front-line management of CP-CML. Based on attainment of faster and higher rates of complete cytogenetic response (CCyR), major molecular response (MMR), and complete molecular response (CMR), and a trend for lower ...

abstract = "In the present study we combined interferon (IFN) and hydroxyurea (HU) treatment, intensive chemotherapy and autologous stem cell transplantation (SCT) in newly diagnosed chronic myelogenous leukemia patients aged below 56 years, not eligible for allogeneic SCT. Patients who had an HLA-identical sibling donor and no contraindication went for an allogeneic SCT (related donor, RD). After diagnosis, patients not allotransplanted received HU and IFN to keep WBC and platelet counts low. After 6 months patients with Ph-positive cells still present in the bone marrow received 1-3 courses of intensive chemotherapy. Those who became Ph-negative after IFN+HU or after 1-3 chemotherapy courses underwent autologous SCT. Some patients with poor cytogenetic response were allotransplanted with an unrelated donor (URD). IFN+HU reduced the percentage of Ph-positive metaphases in 56{\%} of patients, and 1 patient became Ph-negative. After one or two intensive cytotherapies 86 and 88{\%} had a Ph ...

Chronic myeloid leukaemia. Light micrograph of blood cells from bone marrow in a case of chronic myeloid leukaemia. Leukaemia is a cancer where certain blood cells form in excess. There are several chronic forms, classified according to the type of cell affected. Chronic myeloid leukaemia is a cancer affecting the myeloid tissue (bone marrow), specifically the white blood cell precursors (myeloblasts) that form a type of white blood cell known as granulocytes. The pink cells are precursor or white blood cells. The pale orange ones are red bloods cells. Magnification: x1000 when printed at 10 centimetres across. - Stock Image C015/1835

Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder of a pluripotent stem cell. The natural history of CML has a triphasic clinical course comprising of an initial chronic phase (CP), which is characterized by expansion of functionally normal myeloid cells, followed by an accelerated phase (AP) and finally a more aggressive blast phase (BP), with loss of terminal differentiation capacity. On the cellular level, CML is associated with a specific chromosome abnormality, the t(9; 22) reciprocal translocation that forms the Philadelphia (Ph) chromosome. The Ph chromosome is the result of a molecular rearrangement between the c-ABL proto-oncogene on chromosome 9 and the BCR (breakpoint cluster region) gene on chromosome 22. The BCR/ABL fusion gene encodes p210 BCR/ABL, an oncoprotein, which, unlike the normal p145 c-Abl, has constitutive tyrosine kinase activity and is predominantly localized in the cytoplasm. While fusion of c-ABL and BCR is believed to be the primary cause of the ...
Imatinib mesylate (Gleevec; Novartis) has been successfully employed in the treatment of Philadelphia-positive chronic myeloid leukaemia (Ph+ CML) (Deininger et al, 2005). Although imatinib restores a polyclonal haemopoiesis in over 90% of patients, development of clonal chromosome abnormalities in Ph-negative cells (Ph) clonal evolution) occurs in about 15% of cases with a complete cytogenetic remission (CCR). This phenomenon has been very rarely observed in patients treated with interferon-a and/or cytotoxic agents. As the biological and clinical significance of these clones are still unclear, we investigated two cases of CML in chronic phase, not previously treated with genotoxic agents or drugs, in which imatinib therapy lead to the emergence of Ph) clones characterised by an abnormality initially disclosed in the Ph+ cells, a picture found only in two other cases in the literature (Gozzetti et al, 2003; Royer-Pokora et al, 2003). In patient 1, all metaphases at diagnosis carried both the Ph ...
Chronic myeloid leukemia often starts with an indolent chronic phase which, before treatment with imatinib was introduced, progressed in 4-6 years via an accelerated phase to acute leukemia. In the accelerated phase, the number of blasts and basophilic granulocytes increase in peripheral blood. The symptoms also increase in parallel and the condition is then more difficult to treat. This phase can last up to one year and then evolve into the blast phase (transformation). The disease profile is then acute leukemia where the immunophenotype can be lymphoblastic or myeloblastic. The prognosis is poor in these cases. The tyrosine kinase inhibitor imatinib is the most effective medication for treatment of chronic myeloid leukemia. An allogeneic stem cell transplantation (myeloablative/non-myeloablative) is the only treatment method which, with assurance, can cure the disease. Treatment with hydroxy urea (HU) gives longer survival than busulfan. Treatment with interferon-a gives approximately 6 months ...
0.000). Patients having highly positive value may grow some kinase domain mutations causing resistance to prescribed TKI and have evolved into accelerated (AP) or relapse phases (data not shown).. The patients who had achieved the complete cytogenetic response (CCYR) within first 6 months and currently still in CCYR and surviving were also analyzed. Those patients who had not achieved the cytogenetic remission within first 6 months did not show good prognosis. Some of them achieved complete response, but some of them were in AP phase. The BCR-ABL1 fusion protein assay showed considerable consistency with RQ-PCR and cytogenetic results. Studying molecular response groups (Table 6), we have found a distinct difference in MFI values such as complete molecular response (CMR) patients are also negative to be detected for BCR-ABL protein by fluorescence based flow cytometry assay (mean MFI 1.24). Mean MFI of mMR group, being 2.61, indicates clearly the difference in response levels.. The discrepancy ...
Nilotinib, sold under the brand name Tasigna, is a medication used to treat chronic myelogenous leukemia (CML) which has the Philadelphia chromosome.[2] It may be used both in initial cases of chronic phase CML as well as in accelerated and chronic phase CML that has not responded to imatinib.[2][3] It is taken by mouth.[3] Common side effects may include low platelets, low white blood cells, anemia, rashes, vomiting, diarrhea, and joint pains.[3] Other serious side effects may include QT prolongation, sudden death, pancreatitis, and liver problems.[3] It is not safe for use during pregnancy.[3] Nilotinib is a Bcr-Abl tyrosine kinase inhibitor and works by interfering with signalling within the cancer cell.[3] Nilotinib was approved for medical use in the United States in 2007.[3] It is on the World Health Organizations List of Essential Medicines, the safest and most effective medicines needed in a health system.[4] In the United Kingdom it costs the NHS £2,432.85 per month as of 2018.[5] In ...
Mutations in the ABL1 gene are associated with chronic myelogenous leukemia (CML). In CML, the gene is activated by being translocated within the BCR (breakpoint cluster region) gene on chromosome 22. This new fusion gene, BCR-ABL, encodes an unregulated, cytoplasm-targeted tyrosine kinase that allows the cells to proliferate without being regulated by cytokines. This, in turn, allows the cell to become cancerous. This gene is a partner in a fusion gene with the BCR gene in the Philadelphia chromosome, a characteristic abnormality in chronic myelogenous leukemia (CML) and rarely in some other leukemia forms. The BCR-ABL transcript encodes a tyrosine kinase, which activates mediators of the cell cycle regulation system, leading to a clonal myeloproliferative disorder. The BCR-ABL protein can be inhibited by various small molecules. One such inhibitor is imatinib mesylate, which occupies the tyrosine kinase domain and inhibits BCR-ABLs influence on the cell cycle. Second generation BCR-ABL ...
Chronic myeloid leukemia (CML) is a clonal myeloproliferative stem cell disease which is distinguished by an increased number of mature and immature granulocytes in peripheral blood, bone marrow, with increased granulocytopoiesis and splenomegaly. The disease is defined by the presence of the BCR-ABL fusion gene. This anomaly is probably necessary and sufficient for the development of chronic myeloid leukemia. ...
This is the first study to demonstrate that the use of imatinib places a large financial burden on Japanese CML patients, who live in a nation with universal health insurance coverage. In countries where patients must pay a part of their medical expenses, such as Japan, those who require expensive medications incur an enormous financial burden. For example, out-of-pocket expenses and final co-payments among patients receiving imatinib in 2008 were approximately 12,000 and 3,600 USD, respectively. Their annual out-of-pocket expenses were about 10 times those of an average healthy Japanese person [13]. These medical expenses continue for as long as the patients are prescribed imatinib, creating an economic problem that is also observed in many other developed countries [14].. Of the 204 patients who had considered discontinuing their imatinib treatment for reasons other than side effects, 182 (90 %) had considered it for financial reasons.

Dr. Radich explored the clinical decision-making regarding the selection of therapies for CML and emphasized that response milestones as listed in the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for CML should guide the way. For upfront therapy, Dr. Radich noted that one could start with either imatinib or one of the newer agents, based on clinical features (such as the Sokal score), comorbities, and treatment goals. Regardless of the first agent used, it is important to give initial therapy a fair trial before considering it ineffective, he added.. The first milestone is the 3-month BCR-ABL/ABL percentage. According to the NCCN Guidelines, if the BCR-ABL/ABL is less than 10% (indicative of a lack of response), it may be time to consider a second-generation agent. However, the European LeukemiaNet (ELN) guidelines are a bit more patient: if the BCR-ABL/ABL is less than 10% at 6 months, they suggest considering a switch to another agent, noted Dr. Radich.. "Frankly, there are ...
Chronic myelogenous leukemia (CML) is slow-progressing and associated with a specific genetic abnormality in the cell, called the Philadelphia chromosome.
... is the type of cancer of the blood cells, deadly because it progresses more slowly than the acute forms of leukemia. A lot of white cells, known as granulocytes, are produced by the bone marrow, gradually crowding the bone marrow, and interfering with the normal production of blood cells. This is the forum for discussing anything related to this health condition

The advanced phases of chronic myeloid leukemia (CML) are known to be more resistant to therapy. This resistance has been associated with the overexpression of ABCB1, which gives rise to the multidrug resistance (MDR) phenomenon. MDR is characterized by resistance to nonrelated drugs, and P-glycoprotein (encoded by ABCB1) has been implicated as the major cause of its emergence. Wnt signaling has been demonstrated to be important in several aspects of CML. Recently, Wnt signaling was linked to ABCB1 regulation through its canonical pathway, which is mediated by β-catenin, in other types of cancer. In this study, we investigated the involvement of the Wnt/β-catenin pathway in the regulation of ABCB1 transcription in CML, as the basal promoter of ABCB1 has several β-catenin binding sites. β-catenin is the mediator of canonical Wnt signaling, which is important for CML progression. In this work we used the K562 cell line and its derived MDR-resistant cell line Lucena (K562/VCR) as CML study models. Real
The BCR-ABL1 oncoprotein is found in a subset of patients with ALL carrying the Philadelphia chromosome. This translocation is the most common cytogenetic abnormality in adults, with ALL occurring in 25% of patients (33). BCR-ABL1 defines a high-risk group and, as such, patients receive intensive chemotherapy in combination with ABL TKIs and are considered for hematopoietic stem cell transplantation (HSCT). Despite the great success with combination of high-dose ABL TKIs and intensive chemotherapy, there are still drawbacks that need to be addressed. Above all, 40% of patients, even with HSCT, have relapse of the disease. Furthermore, it is not clear whether responsive patients without HSCT cannot have relapse of the disease, as there is evidence that BCR-ABL1-positive leukemia stem cells remain present in the patients bone marrow even after years of therapy. Therefore, it is necessary to define targets in BCR-ABL1-positive leukemia stem cells that may be candidates for new treatment ...
The exchange of genetic information that produces the Philadelphia chromosome brings together two genes: the BCR (breakpoint cluster region) gene on chromosome 22 and the ABL (Ableson leukemia virus) gene on chromosome 9. The combination of these two genes into the single BCR-ABL gene results in the production of a protein that contributes to uncontrolled cell growth.. Initially in CML, there is a gradual increase in mature, abnormal myeloid cells in the bone marrow. These cells eventually spill into the blood and other organs, causing symptoms such as fatigue from anemia or an enlarged spleen. The increase in leukemic cell numbers occurs slowly at first and is referred to as the chronic phase, but these cells invariably begin to increase more rapidly and/or include less mature cells, resulting in the accelerated or blastic phase. In order to understand the best treatment options available for chronic myeloid leukemia, it is important to know the phase of leukemia, since all new treatment ...

Chronic myeloid leukemia (CML) results from hematopoietic stem cell transformation by the BCR-ABL kinase. Despite the success of BCR-ABL tyrosine kinase inhibitors (TKIs) in treating CML patients, leukemia stem cells (LSCs) resist elimination and persist as a major barrier to cure. Previous studies suggest that overexpression of the sirtuin 1 (SIRT1) deacetylase may contribute to LSC maintenance in CML. Here, by genetically deleting SIRT1 in transgenic CML mice, we definitively demonstrated an important role for SIRT1 in leukemia development. We identified a previously unrecognized role for SIRT1 in mediating increased mitochondrial oxidative phosphorylation in CML LSCs. We showed that mitochondrial alterations were kinase independent and that TKI treatment enhanced inhibition of CML hematopoiesis in SIRT1-deleted mice. We further showed that the SIRT1 substrate PGC-1α contributed to increased oxidative phosphorylation and TKI resistance in CML LSCs. These results reveal an important role for ...

Chronic Myeloid Leukemia (CML) is characterized by increased and unregulated growth of myeloid cells in the bone marrow and accumulation of these cells in the blood. Most CML is caused by a chromosomal abnormality that results in a fusion between Abl tyrosine kinase and BCR gene on chromosome 2, which results in a constitutively active tyrosine kinase. Most CMLs are treated with tyrosine kinase inhibitors (TKI) such as imatinib. Some forms of CML, however, are resistant to TKI treatment and proceed independent of BCR-Abl1 activity. A recent colloborative study utilizing Cellectas unique platform in paired imatinib-resistant and imatininb-sensitive K-562 CML cell lines to identify other genes whose knockdown might play a role in the survival of the imatinib-resistant cells. This loss-of-function shRNA library screen identified RAN and XPO1, which are components of the nucleocytoplasmic transport complex.. When these genes were knocked down and the cells were treated with imatinib, the cells were ...

The primary objective is to describe the effectiveness of dasatinib (Sprycel) in chronic myeloid leukemia patients in China in the real-world clinical practice
Background: The development of cancer results from an imbalance between exposure to carcinogens and the capacity of various enzyme systems engaged in activation or in the detoxification of xenobiotics. The aim of the present study is to investigate the association of GSTP1, GSTM1 and GSTT1 gene polymorphisms in susceptibility to Chronic Myeloid Leukaemia (CML). Methods: A total of 200 CML patients and 100 controls were enrolled in a case-control study with GSTM1 and GSTT1 analysis with PCR and GSTP1 analysis with PCR-RFLP. Results: The GSTT1 null genotype was significantly higher among CML patients suggesting that this genotype is associated with an increased risk of CML. It was found in 42% of cases as compared with 21% of the controls, (OR =2.78, 95% CI: 1.59 - 4.85; p-value =0.000). The presence of the GSTT1 genotype may thus be considered a protective factor for CML. The frequency of individuals carrying GSTM1 null genotype was slightly higher in the control group but this difference was not
Dasatinib inhibits wild type Bcr Abl and all members of the Src household, with an IC50 1 nM. Even so it is not clear from preceding reports whether Src kinase activity is elevated in main progenitors from CML clients.. In addition the effects of Dasatinib on Src kinase activity in primary CML progenitor cells and on downstream signaling actions and apoptosis regulating mechanisms have not been studied. In this research we evaluated Src activity in primitive human CML progenitors from different phases of illness, and investigated the effects PARP of Dasatinib on Bcr Abl and Src kinase activity and downstream development signaling pathways in CP CML progenitors. Peripheral blood samples were obtained from newly diagnosed CML sufferers. Peripheral blood stem cell and umbilical cord blood samples have been obtained from wholesome donors. This research was approved by the Institutional Critique Boards at City of Hope Cancer Center, in accordance with an assurance filed with and authorized by the ...

Tasigna® (nilotinib) is a cancer medication manufactured by Novartis that was approved in the U.S. in 2007 for the treatment of Philadelphia chromosome-positive Chronic Myeloid Leukemia (Ph+ CML).. In April 2013, the prescribing information for Tasigna was updated in Canada after health officials warned that 277 cases of atherosclerosis had been reported worldwide between January 2005 and January 2013.. Atherosclerosis is a life-threatening artery disease that can cause narrowing of the blood vessels that carry oxygen-rich blood to the body. It is a risk-factor for blood clots, heart attack, stroke, and death.. Canadian health experts recommended that patients on Tasigna should be closely monitored for signs of arterial disease, but these warnings never trickled down to doctors in the U.S. or their patients.. In March 2016, the family of a man from California who died of atherosclerosis complications after taking Tasigna filed a lawsuit accusing Novartis of failing to warn patients in the U.S. ...
Background: Tyrosine kinase inhibitors (TKIs) have increased survival dramatically for patients with chronic myeloid leukemia (CML), but continuous administration of these drugs may elicit long-term toxicity. Objective: To investigate the incidence of vascular events in patients with CML treated with first-and second-generation TKIs. Design: Retrospective cohort study using nationwide population-based registries. Setting: Sweden. Patients: All patients diagnosed with chronic-phase CML in Sweden from 2002 to 2012 and treated with a TKI, and 5 age- and sex-matched control individuals per patient. Measurements: Relative risks, expressed as incidence rate ratios comparing patients with control individuals, were calculated. Events per 1000 person-years were assessed in interdrug comparisons. Results: 896 patients, 94.4% with documented TKI treatment, were followed for a median of 4.2 years. There were 54 arterial and 20 venous events in the CML cohort, corresponding to relative risks of 1.5 (95% CI, ...

The WD40-repeat domain of AHI-1 interacts with BCR-ABL, whereas the N-terminal region interacts with JAK2; loss of these interactions statistically significantly increased the IM sensitivity of CML cells. Disrupting this complex with a combination of IM and an orally bioavailable selective JAK2 inhibitor (TG101209 [TG]) statistically significantly induced death of AHI-1-overexpressing and IM-resistant cells in vitro and enhanced survival of leukemic mice, compared with single agents (combination vs TG alone: 63 vs 53 days, ratio = 0.84, 95% confidence interval [CI] = 0.6 to 1.1, P = .004; vs IM: 57 days, ratio = 0.9, 95% CI = 0.61 to 1.2, P = .003). Combination treatment also statistically significantly enhanced apoptosis of CD34+ leukemic stem/progenitor cells and eliminated their long-term leukemia-initiating activity in NSG mice. Importantly, this approach was effective against treatment-naive CML stem cells from patients who subsequently proved to be resistant to IM therapy. ...
Chronic myeloid leukaemia has a worldwide incidence of 1 to 2 per 100 000 population. Most cases are caused by translocation of the distal end of chromosome 9 on to chromosome 22 (known as a Philadelphia chromosome), which leads to the creation of a fusion protein expressed from the fusion gene formed by juxtaposition of parts of the ...
Summary A high-dimensional metabolomics screen to diagnose and monitor chronic myeloid leukemia (CML) has been developed. Over 3000 metabolites are detected to yield a ‘cytogenetic signature’ that confirms the presence of cells bearing the Philadelphia chromosome, a genetic marker for CML. Through comparison of the levels of these metabolites to those found in the blood of disease-free individuals, diagnosis can be made as to the presence and severity of the cancer using only one blood sample. This rapid and sensitive analytic technology reduces time and overall cost associated with CML diagnosis and enhances patient comfort and well-being.

This study investigated the incidence of side-effects in patients with Chronic Myeloid Leukaemia whi were on treatment with Dasatinib.
The Philadelphia chromosome is a rearrangement that is present in the white blood cells of 90% of people with chronic myelogenous leukaemia (CML). It arises from a chromosome 9 and chromosome 22 translocation, generating a fusion gene from the breakpoint cluster region (BCR) and the Abelson leukaemia (ABL1) gene. Several breakpoints have been identified in BCR, and the fusion of these different breakpoints to ABL1 results in the production of a non-regulated tyrosine kinase, transforming normal cells to neoplastic CML cells, and leading to unlimited propagation. BCR exon 13-ABL1 exon 2 (e13a2, p210) and BCR exon 14-ABL1 exon 2 (e14a2, p210) have been found in more than 95% of CML patients (Fig. 1). ...
Yes-associated protein (YAP), an essential component of Hippo pathway, was identified as an oncoprotein which participated in the progression of various malignancies. However, its role in chronic myeloid leukemia (CML) remains to be further clarified. The expression of YAP in CML cells was determined by western blotting. Next, the effects of YAP knockdown and YAP inhibitor on CML cells were evaluated by MTT assay, flow cytometry (FCM) and Wrights staining. Moreover, K562 induced mice model was employed to further investigate the role of YAP in vivo. YAP was overexpressed in CML cells. Knockdown of YAP by si-RNA or inhibition the function of YAP using verteporfin (VP) not only inhibited the proliferation, induced the apoptosis of CML cells but also reduced the expression of YAP target genes c-myc and survivin. Additionally, VP enhanced the efficacy of imatinib (IM) in vitro and suppressed leukemogenesis in vivo. Our results indicate that YAP may play an important role in the proliferation and
Treatment of CML has notably been improved by the development of imatinib mesylate, a tyrosine kinase inhibitor that blocks the kinase activity of BCR-ABL1, defining this drug as the gold standard first-line therapy for CML patients (36, 40, 41). In contrast, it has been recently shown that imatinib mesylate does not inactivate all BCR-ABL1-activated signaling pathways that are essential for CML cell survival (42). This implies that persistent malignant progenitors can be a potential source of relapse in CML patients and that there is a need to improve our understanding of the biology of CML to provide new targets for therapy. The recent implication of miRNAs in the regulation of important biological processes altered in CML, such as cell cycle, apoptosis, and adhesion (2), establishes these small RNA molecules as potential players in CML pathogenesis.. The result of the current study identifies certain miRNAs (hsa-miR-10a, hsa-miR-96, hsa-miR-150, and hsa-miR-151) to be abnormally regulated in ...
Apo-Imatinib: Imatinib belongs to a family of medications called protein tyrosine kinase inhibitors. It is used to treat adults and children who have been newly diagnosed with Philadelphia chromosome positive chronic myeloid leukemia (Ph+ CML) in chronic phase. It works by affecting enzymes that play a role in certain cancer cells.
Blind is found among people with Chronic myeloid leukaemia, especially for people who are female, 60+ old also have Diabetes and take medication Gleevec.
Imatinib became the standard treatment for chronic myeloid leukemia (CML) about 20 years ago, which was a major breakthrough in stabilizing the pathology and improving the quality of life of patients. However, the emergence of resistance to imatinib and other tyrosine kinase inhibitors leads researchers to characterize new therapeutic targets. Several studies have highlighted the role of histone deacetylase 6 (HDAC6) in various pathologies, including cancer. This protein effectively intervenes in cellular activities by its primarily cytoplasmic localization. In this review, we will discuss the molecular characteristics of the HDAC6 protein, as well as its overexpression in CML leukemic stem cells, which make it a promising therapeutic target for the treatment of CML.
Chronic myeloid leukemia (CML) accounts for 15% of diagnosed leukemias. The annual incidence in two Polish regions has been calculated for 0.7/100,000 of general population. Introduction of tyrosine kinase inhibitors (TKIs) have substantially improved not only the prognosis of CML, but also changed the treatment goals, and the expectations of patients and physicians. The goals of CML therapy include: to prevent the progression towards accelerated phase and blastic phase, to eliminate the risk of death from leukemia, to prolong the length of survival to comparable of healthy population and to attain a quality of life comparable to healthy people. Patients treated up-front with second generation TKIs (2GTKI) have a better chance to achieve faster and deeper response to therapy. Most of patients receiving 2GTKI in first line or e.g. nilotinib after initial phase of imatinib therapy can achieve very deep molecular response (MR4.5), which is a key criterion for discontinuation studies. The results of ...
Results: Significant associations were detected between the IL-18 rs187238(G/C) polymorphism and chronic leukemia. A higher prevalence of the C allele was found in CML cases with respect to controls. The GC heterozygous and CC homozygous genotypes were associated with risk of CML when compared with controls. However, prevalence of the C allele was not significantly high in CLL cases with respect to controls. There was only a significant difference between the homozygous CC genotype of CLL patients and the control group; thus, it can be concluded that the CC genotype may be associated with the risk of CLL. Based on our data, there were no significant associations between the IL-18 rs61667799(G/T), rs5744227(C/G), or rs5744228(A/G) polymorphisms and CLL or CML ...

MicroRNA-mediated posttranscriptional regulation is an important epigenetic regulatory mechanism of gene expression, and its dysregulation is involved in the development and progression of a variety of malignancies, including chronic myeloid leukemia (CML). The BCR-ABL1 fusion gene is not only the initiating factor of CML, but it is also an important driving factor for blastic transformation. Tyrosine kinase inhibitors (TKIs) targeting BCR-ABL1 tyrosine kinase activity, represented by imatinib, are currently the first-line treatment for CML. However, due to primary resistance or secondary resistance caused by mutations in the BCR-ABL1 kinase domain, TKIs cannot completely prevent the progression of CML; thus, the study of BCR-ABL1 gene expression regulation is of great significance. In this study, bioinformatics analysis and our results showed that miR-96 could directly bind to the 3UTR region of BCR-ABL1 to regulate fusion protein expression, thereby regulating its downstream signaling pathway ...
