The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel.

Purine nucleoside phosphorylase in chronic lymphocytic leukemia (CLL). (1/1986)

Purine nucleoside phosphorylase (PNP), the enzyme schematically next to adenosine deaminase in the purine salvage pathway, has been demonstrated cytochemically in peripheral blood lymphocytes of healthy subjects and chronic lymphocytic leukemia (CLL) patients. The enzyme activity is confined to the cytosol. In healthy subjects the majority of lymphocytes are strongly reactive for PNP, whereas the rest are devoid of cytochemically demonstrable activity. The percentage of PNP-positive cells largely corresponds to the number of E rosette-forming cells and is inversely proportional to the number of Ig-bearing cells. In six of seven CLL patients studied only a minor percentage of the lymphocytes showed strong PNP activity, whereas the large majority (88%--98%) possessed trace activity. Such patients have a high number of Ig-bearing cells and a low number of E rosette-forming cells. A different pattern of markers was found in the lymphocytes of the seventh CLL patient: 66% were strongly reactive for PNP, an important number formed E rosettes, and a minor percentage were Ig bearing. These data indicate that PNP can be useful as a "nonmembrane" marker in the differentiation of the B and T cell origin in CLL and deserves to be studied in other lymphoproliferative disorders.  (+info)

Increased sensitivity of hydroxyurea-resistant leukemic cells to gemcitabine. (2/1986)

Tumor cell resistance to certain chemotherapeutic agents may result in cross-resistance to related antineoplastic agents. To study cross-resistance among inhibitors of ribonucleotide reductase, we developed hydroxyurea-resistant (HU-R) CCRF-CEM cells. These cells were 6-fold more resistant to hydroxyurea than the parent hydroxyurea-sensitive (HU-S) cell line and displayed an increase in the mRNA and protein of the R2 subunit of ribonucleotide reductase. We examined whether HU-R cells were cross-resistant to gemcitabine, a drug that blocks cell proliferation by inhibiting ribonucleotide reductase and incorporating itself into DNA. Contrary to our expectation, HU-R cells had an increased sensitivity to gemcitabine. The IC50 of gemcitabine was 0.061 +/- 0.03 microM for HU-R cells versus 0.16 +/- 0.02 microM for HU-S cells (P = 0.005). The cellular uptake of [3H]gemcitabine and its incorporation into DNA were increased in HU-R cells. Over an 18-h incubation with radiolabeled gemcitabine (0.25 microM), gemcitabine uptake was 286 +/- 37.3 fmol/10(6) cells for HU-R cells and 128 +/- 8.8 fmol/10(6) cells for HU-S cells (P = 0.03). The incorporation of gemcitabine into DNA was 75 +/- 6.7 fmol/10(6) cells for HU-R cells versus 22 +/- 0.6 fmol/10(6) cells for HU-S cells (P < 0.02). Our studies suggest that the increased sensitivity of HU-R cells to gemcitabine results from increased drug uptake by these cells. This, in turn, favors the incorporation of gemcitabine into DNA, resulting in enhanced cytotoxicity. The increased sensitivity of malignant cells to gemcitabine after the development of hydroxyurea resistance may be relevant to the design of chemotherapeutic trials with these drugs.  (+info)

Skin reaction and antibody responses in guinea-pigs sensitized to human leukaemia cells or their nuclei in combination with Bacillus Calmette-Guerin. (3/1986)

Guinea-pigs sensitized by subcutaneous injection of chronic lymphatic leukaemia (CLL) cells combined with Bacillus Calmette-Guerin (BCG) displayed good skin reacitons 24 and 48 h after challenge with CLL cells. Equally good responses were also demonstrated using nuclei from the leukaemic cells in combination with BCG. These reactions were significantly greater than those produced in the same manner but without BCG. Sera form the animals were examined for the presence of antibodies against CLL cells by cytotoxicity and immunofluorescence techniques. Only samples from guinea-pigs innoculated with CLL cells were found to contain significant antibodies. Histological examination showed that whereas leukaemic cells persisted at the sensitizing injection site leukaemic cell nuclei could not be visualized. It is suggested that because leukaemic cell nuclei in combination with BCG are able to induce good skin reactivity without provoking a vigorous humoral antibody response they may have possible advantages over leukaemic cells when used for immunotherapy.  (+info)

The P190, P210, and P230 forms of the BCR/ABL oncogene induce a similar chronic myeloid leukemia-like syndrome in mice but have different lymphoid leukemogenic activity. (4/1986)

The product of the Philadelphia chromosome (Ph) translocation, the BCR/ABL oncogene, exists in three principal forms (P190, P210, and P230 BCR/ABL) that are found in distinct forms of Ph-positive leukemia, suggesting the three proteins have different leukemogenic activity. We have directly compared the tyrosine kinase activity, in vitro transformation properties, and in vivo leukemogenic activity of the P190, P210, and P230 forms of BCR/ABL. P230 exhibited lower intrinsic tyrosine kinase activity than P210 and P190. Although all three oncogenes transformed both myeloid (32D cl3) and lymphoid (Ba/F3) interleukin (IL)-3-dependent cell lines to become independent of IL-3 for survival and growth, their ability to stimulate proliferation of Ba/F3 lymphoid cells differed and correlated directly with tyrosine kinase activity. In a murine bone marrow transduction/transplantation model, the three forms of BCR/ABL were equally potent in the induction of a chronic myeloid leukemia (CML)-like myeloproliferative syndrome in recipient mice when 5-fluorouracil (5-FU)-treated donors were used. Analysis of proviral integration showed the CML-like disease to be polyclonal and to involve multiple myeloid and B lymphoid lineages, implicating a primitive multipotential target cell. Secondary transplantation revealed that only certain minor clones gave rise to day 12 spleen colonies and induced disease in secondary recipients, suggesting heterogeneity among the target cell population. In contrast, when marrow from non- 5-FU-treated donors was used, a mixture of CML-like disease, B lymphoid acute leukemia, and macrophage tumors was observed in recipients. P190 BCR/ABL induced lymphoid leukemia with shorter latency than P210 or P230. The lymphoid leukemias and macrophage tumors had provirus integration patterns that were oligo- or monoclonal and limited to the tumor cells, suggesting a lineage-restricted target cell with a requirement for additional events in addition to BCR/ABL transduction for full malignant transformation. These results do not support the hypothesis that P230 BCR/ABL induces a distinct and less aggressive form of CML in humans, and suggest that the rarity of P190 BCR/ABL in human CML may reflect infrequent BCR intron 1 breakpoints during the genesis of the Ph chromosome in stem cells, rather than intrinsic differences in myeloid leukemogenicity between P190 and P210.  (+info)

Selective, covalent modification of beta-tubulin residue Cys-239 by T138067, an antitumor agent with in vivo efficacy against multidrug-resistant tumors. (5/1986)

Microtubules are linear polymers of alpha- and beta-tubulin heterodimers and are the major constituents of mitotic spindles, which are essential for the separation of chromosomes during mitosis. Here we describe a synthetic compound, 2-fluoro-1-methoxy-4-pentafluorophenylsulfonamidobenzene (T138067), which covalently and selectively modifies the beta1, beta2, and beta4 isotypes of beta-tubulin at a conserved cysteine residue, thereby disrupting microtubule polymerization. Cells exposed to T138067 become altered in shape, indicating a collapse of the cytoskeleton, and show an increase in chromosomal ploidy. Subsequently, these cells undergo apoptosis. Furthermore, T138067 exhibits cytotoxicity against tumor cell lines that exhibit substantial resistance to vinblastine, paclitaxel, doxorubicin, and actinomycin D. T138067 is also equally efficacious in inhibiting the growth of sensitive and multidrug-resistant human tumor xenografts in athymic nude mice. These observations suggest that T138067 may be clinically useful for the treatment of multidrug-resistant tumors.  (+info)

Detection of p53 gene mutations in human leukemia by PCR-SSCP analysis and direct nucleotide sequencing. (6/1986)

OBJECTIVE: To look for mutations of the p53 gene in leukemic patients and study the relationship between abnormalities in p53 gene and leukemogenesis. METHODS: The peripheral blood and Bone Marrow Samples were collected from 36 patients with various leukemia types including 14 cases of lymphocytic leukemia [8 cases of acute lymphocytic leukemia (ALL), 4 cases of chronic lymphocytic leukemia (CLL), 2 cases of hairy cell leukemia (HCL)] and 22 cases of myelocytic leukemia [11 cases of acute nonlymphocytic leukemia (ANLL), 11 cases of chronic myelocytic leukemia (CML)]. DNA structures of exon 5-8 of the p53 gene were scanned by PCR-SSCP (single strand conformation polymorphism analysis of polymerase chain reaction products). The appropriate DNA fragments were amplified, Purified and sequenced directly. RESULTS: By PCR-SSCP analysis, shifts in electrophoretic mobility of the p53 gene were detected in 3 of 14 patients with lymphocytic leukemia (2 ALL and 1 CLL), but none in 22 patients with myelocytic leukemia including one in blastic crisis. Direct nucleotide sequencing in one patient with ALL showed transition of CTG to CAG at codon 257 of exon 7, resulting in a change of its encoded amino acids from aspartic acid to valine. To our knowledge, the mutation at this codon has not been previously reported hitherto. CONCLUSIONS: The p53 gene mutations are specifically associated with lymphocytic leukemia. Alternations of the p53 gene may play a certain role in leukemogenesis in some cases of lymphocytic leukemia.  (+info)

Effects of spin labeled derivatives of podophyllotoxin on cell cycle and macromolecular synthesis in human lymphoid leukemia Molt 4B cells. (7/1986)

AIM: To examine the effect of the spin labeled derivatives of podophyllotoxin, N-podophyllic acid-N"-[4-(2,2,6,6-tetramethyl-1-piperidinyloxy)] thiosemicarbazide (GP4) and 4-[4"-(2",2",6",6"-tetramethyl-1"-piperidinyloxy) amino]-4'-demethylepipodophyllotoxin (GP7) on the cell cycle and macromolecular synthesis of human lymphoid leukemia Molt 4B cells in vitro. METHODS: MTT assay, 3H incorporation, and flow cytometer were used. RESULTS: GP4, GP7, and etoposide 0.02-100 mmol.L-1 cultured for 48 h inhibited the proliferation of human lymphoid leukemia Molt 4B cells. IC50 values of GP4, GP7, and etoposide were 0.11, 4.7, and 1.6 mmol.L-1, respectively. DNA and protein syntheses were obviously suppressed by GP4, GP7, and etoposide 10 mmol.L-1 for 48 h. After Molt 4B cells were treated with GP4, GP7, and etoposide 10 mmol.L-1 for 6 and 12 h, the mitotic index was increased by GP4 and reduced by GP7 and etoposide. According to flow cytometric BrdU/DNA analysis, GP4 slightly retarded S phase and mainly arrested cell cycle progression in G2/M phase, whereas GP7 similar to etoposide induced cells accumulated at S phase and retarded the cells in G2 phase. CONCLUSION: GP4 and GP7 inhibit the proliferation of Molt 4B cells, but the mechanisms are different.  (+info)

Cleavage of the ALL1 gene in acute lymphoid leukemia before treatment disappears in relapse. (8/1986)

BACKGROUND AND OBJECTIVE: ALL1 gene rearrangements are frequently found in secondary acute leukemias (ALs). A site-specific cleavage of the ALL1 gene in a consensus sequence for topoisomerase II recognition has been considered to be the initial step leading to ALL1 rearrangement and subsequent therapy-related AL. The aim of the present study was to evaluate this cleavage in our patients, to analyze whether it is a laboratory-produced artefact and to check whether it persists or causes a real ALL1 gene rearrangement at relapse. DESIGN AND METHODS: We studied ALL1 rearrangement in 74 cases of AL before treatment by Southern blot avoiding room temperature exposure or delay in processing the samples which could produce ALL1 cleavage. DNA was available for two cases with ALL1 cleavage; it was analyzed by three different Southern blots in one and two in the other. One case with ALL1 cleavage was also studied in relapse. RESULTS: The presence of the cleavage of the ALL1 DNA was found in 3 of 74 (4%) patients. Two of these three patients had the ALL1 cleavage in three and two different analyses. One case was positive for ALL1 cleavage at diagnosis, but negative for both ALL1 cleavage and ALL1 rearrangement at relapse. INTERPRETATION AND CONCLUSIONS: The fact that a constant pattern was obtained from the same patients in different DNA preparations, supports the notion that ALL1 cleavage is not a laboratory artefact. The absence of the cleavage in a sample from a relapsed patient suggests that the subclone with the ALL1 cleavage, in this case, did not play a clear role in the pathogenesis of disease recurrence.  (+info)

Treatment for Chronic Lymphatic Leukaemia to Replace Chemotherapy. Chronic lymphocytic leukaemia (CLL) is a malignancy of CD5+ B cells that is characterized by the accumulation of small, mature-appearing lymphocytes in the blood, marrow and lymphoid tissues.
A case report of a patient who developed fatal pneumocystis pneumonia while in remission from acute lymphatic leukaemia is presented.
The close relationship which seems to exist between lymphocytes and plasma cells has recently been the subject of much discussion.1, 2 The frequent occurrence of apparently identical serum protein abnormalities in patients with malignant lymphoma, lymphatic leukemia and multiple myeloma, as demonstrated by paper electrophoresis, has been felt to be of particular significance. The consensus seems to be that plasma cells probably represent transitional forms of lymphocytes, as had been suggested by the work of Sundberg3 and others,4 and that both are capable of synthesizing abnormal serum proteins.. Although serum proteins of the myeloma type have occasionally been reported in ...

A cobalamin-dependent N5-methyltetra-hydrofolate-homocysteine methyltransferase (methyl-transferase) was demonstrated in unfractioned extracts of human normal and leukemia leukocytes. Activity was substantially reduced in the absence of an added cobalamin derivative. Presumably, this residual activity reflects the endogeneous level of holoenzyme. Enzyme activity was notably higher in lymphoid cells than in myeloid cells. Thus, mean specific activities (+/-SD) were: chronic lymphocytic leukemia lymphocytes, 2.15+/-1.16; normal lymphocytes, 0.91+/-0.59; normal mature granulocytes, 0.15+/-0.10; chronic myelocytic leukemia granulocytes, barely detectable activity. Properties of leukocytes enzymes resembled those of methyltransferases previously studied in bacteria and other animal cells. Granulocytes and chronic myelocytic leukemia cells contain a factor or factors that inhibits Escherichia coli enzyme. The data suggest that the prominence of this cobalamin-dependent enzyme in lymphocytes and other ...

The hepatitis C virus (HCV) was characterised in 1989. HCV was transmitted through transfusion of blood/blood products, but injection drug use is now the most common route of transmission. The infection is usually asymptomatic but becomes chronic in about 75%, and in 20 years 15-25% develops liver cirrhosis, with a risk for liver failure and liver cancer. HCV has also been associated with lymphoproliferative disorders. The aim of this thesis was to study morbidity and mortality in a national, population-based cohort of HCV-infected individuals. The study population consisted of all persons with a diagnosed HCV-infection recorded in the national surveillance database. This file was linked to other national registers to obtain information of emigration, deaths, cancers, and inpatient care. All personal identifiers were removed before analysis.. In Paper I the standardized incidence ratios (SIR) for Hodgkins and non-Hodgkins lymphoma (NHL), multiple myeloma, acute and chronic lymphatic leukaemia, ...
Natural killer (NK) cell therapy is used in pediatrics for children with relapsed lymphoid leukemia. These patients normally have a resistance to chemotherapy, therefore, in order to continue on, must receive some kind of therapy. In some cases, NK cell therapy is a choice.[8] NK cells are known for their ability to eradicate tumor cells without any prior sensitization to them.[9] One problem when using NK cells in order to fight off lymphoid leukemia is the fact that it is hard to amount enough of them to be effective.[9] One can receive donations of NK cells from parents or relatives through bone marrow transplants. There are also the issues of cost, purity and safety.[10] Unfortunately, there is always the possibility of Graft vs host disease while transplanting bone marrow. NK cell therapy is a possible treatment for many different cancers such as Malignant glioma.[11] ...

About 3,800 new cases of acute lymphocytic leukemia (ALL) are diagnosed each year in the United States. It is the most common type of leukemia under the age of 15. Children are most likely to develop the disease, but it can occur at any age. Acute lymphocytic leukemia may be called by several names, including acute lymphoid leukemia and acute lymphoblastic leukemia.. ALL results from an acquired (not inherited) genetic injury to the DNA of a single cell in the bone marrow. The disease is often referred to as acute lymphoblastic leukemia because the leukemic cell that replaces the normal marrow is the (leukemic) lymphoblast. The effects are: 1) the uncontrolled and exaggerated growth and accumulation of cells called lymphoblasts or leukemic blasts, which fail to function as normal blood cells and 2) the blockade of the production of normal marrow cells, leading to a deficiency of red cells (anemia), platelets (thrombocytopenia), and normal white cells (especially neutrophils, i.e., ...
Acute lymphoblastic leukaemia. In acute lymphoblastic leukaemia (ALL) the bone marrow makes large numbers of abnormal immature lymphocytes called lymphoblasts. There are various sub-types of ALL. For example, the abnormal lymphoblasts can be immature B or T lymphocytes. ALL can occur at any age, but about 6 in 10 cases occur in children. It is the most common form of leukaemia to affect children.. Acute myeloid leukaemia. In acute myeloid leukaemia (AML) the bone marrow makes large numbers of abnormal immature white blood cells which are derived from a myeloid stem cell. The abnormal immature cells are called blasts. There are various sub-types of AML, depending on exactly what cell type becomes cancerous and at what stage in the maturing process. AML is an uncommon disease. Most cases occur in people aged over 50.. Chronic lymphocytic leukaemia. In chronic lymphocytic leukaemia (CLL) you have many abnormal B lymphocytes. Typically, CLL develops and progresses very slowly - over months or years, ...

Acute lymphatic leukemia (ALL) is the most common cancer in children under the age of 14 years. With optimum treatment, approximately 75 % of children are currently cured, but the treatment consists of severe chemotherapy with many side effects. In collaboration with international research teams, scientists at VIB, KU Leuven and UZ Leuven have identified new genetic mutations that lead to T-ALL, a variant of ALL. They have unmasked the ribosome - the molecular machine in the cell that is involved in the production of proteins - as a weak spot in leukemia cells. Their research has also shown that there is a difference in T-ALL between adults and children. Both findings can be important in the search for improved treatments for T-ALL. ...
743 TRAIL (TNF-related apoptosis inducing ligand) and agonistic anti TRAIL-receptor antibodies exert two main functions on tumor cells: Induction of apoptosis in group A tumor cells and induction of proliferation in group P tumor cells. While induction of apoptosis is the aimed effect during putative anti-tumor therapy using TRAIL, TRAIL-induced tumor cell proliferation should be prevented. Here we report that group P tumor cells characterized by TRAIL-mediated proliferation were found among primary cells of different origin, e.g. of adult patients with acute myeloid leukemia and of children with neuroblastoma or acute lymphatic leukemia. TRAIL-induced proliferation was found in primary tumor cells in the presence of cytotoxic drugs. In primary cells, TRAIL-induced proliferation was associated with resistance towards apoptosis induction by the CD95 system and / or TNF. Inhibition of NFκB disabled TRAIL-induced tumor cell proliferation. In cell lines, loss of caspase-8 or transfection of ...

Scottish Medicines Consortium (SMC) have announced approval of venetoclax, a drug marketed by Janssen as Venclyxto®, for use in Scotland to treat chronic lymphocytic leukaemia (CLL).
BACKGROUND: Therapy targeting Brutons tyrosine kinase (BTK) with ibrutinib has transformed the treatment of chronic lymphocytic leukaemia. However, patients who are refractory to or relapse after ibrutinib therapy have poor outcomes. Venetoclax is a selective, orally bioavailable inhibitor of BCL-2 active in previously treated patients with relapsed or refractory chronic lymphocytic leukaemia. In this study, we assessed the activity and safety of venetoclax in patients with chronic lymphocytic leukaemia who are refractory to or relapse during or after ibrutinib therapy. METHODS: In this interim analysis of a multicentre, open-label, non-randomised, phase 2 trial, we enrolled patients aged 18 years or older with a documented diagnosis of chronic lymphocytic leukaemia according to the 2008 International Workshop on Chronic Lymphocytic Leukemia (IWCLL) criteria and an Eastern Cooperative Oncology Group performance score of 2 or lower. All patients had relapsed or refractory disease after previous ...
The reactivity of five monoclonal antibodies J5, OKB-cALLA, Nu-N1, Nu-N2 and VIL-A1 against the common acute lymphoblastic leukaemia (common-ALL) antigen (glycoprotein 100, CD10); was investigated by indirect immunofluorescence in cell suspensions, and by immunoperoxidase in cytocentrifuge slides of ALL, chronic B cell lymphoproliferative disorders, and plasma cell dyscrasias. The five monoclonal antibodies gave similar positive results with both techniques only in samples of ALL. J5 was positive in variable degrees by immunofluorescence in the majority of B cell disorders examined but this was not confirmed by immunoperoxidase. OKB-cALLA reacted in a similar way to J5 in both techniques, although with a lower percentage of cells by immunofluorescence.

Early attempts at karyotyping chronic lymphocytic leukaemia cells identified trisomy 12 and deletions at 13q,[66] but most laboratories were unable to satisfactorily bring chronic lymphocytic leukaemia cells into mitosis. Only in the past few years have cytogenetic techniques been developed that make this proposition feasible.[65] and [67] Döhner and colleagues showed in a series of 325 patients with chronic lymphocytic leukaemia that chromosomal aberrations can be detected in interphase cells by fluorescence in-situ hybridisation (FISH) in 82% of cases. The most frequent alterations are a deletion on chromosome 13q (55%), trisomy 12 (18%), and a deletion on chromosome 11q (16%). A deletion on chromosome 17p, affecting the TP53 protein, is seen less frequently (7%). The presence of a 17p or 11q deletion is associated with poor prognosis and predominates in advanced stages of chronic lymphocytic leukaemia and in patients with unmutated IGHV genes, whereas the 13q deletion or a normal karyotype ...
97C5 recognizes human CD10, the human common acute lymphoblastic leukemia antigen (CALLA). CD10 is a 100 kDa cell surface molecule identical to human membrane-associated neutral endopeptidase (NEP) and also known as neprilysin or enkephalinase. Human CD10 is expressed on a wide variety of normal and neoplastic cell types from different tissues including neural and hematopoietic cells. It is expressed on pre- and pro-B cells and is involved in B cell development and differentiation. The antigen is also present on mature neutrophils, T cell precursors, and some T cell leukemias/lymphomas. Furthermore, CD10 is expressed on neoplastic cells of several B lymphoid leukemias/lymphomas. - Nederland

Pharmacological agents that inhibit enzymes of the B-cell receptor (BCR) pathway are of increasing importance in the treatment of B-cell malignancies. These include inhibitors of Bruton tyrosine kinase (BTK), phosphatidylinositol 3-kinase (PI3K), splenic tyrosine kinase and protein kinase C beta. Two agents are already approved in the USA and Europe: ibrutinib, a BTK inhibitor, for the treatment of chronic lymphatic leukaemia (CLL), mantle cell lymphoma (MCL) and Waldenstroms macroglobulinemia;and idelalisib, a PI3K delta inhibitor, for the treatment of CLL and follicular lymphoma. In addition, the role of these drugs in diffuse large B-cell lymphoma and marginal zone lymphoma is under investigation, as single agents and in combination with chemotherapy. In CLL, both ibrutinib and idelalisib have an established role as first-line therapy in patients with del(17p), and in MCL, ibrutinib is a standard option for patients relapsing after chemoimmunotherapy. Unexpected toxicities have been ...
Background: Several studies show that bone marrow (BM) microenvironment and hypoxia condition can promote the survival of leukemic cells and induce resistance to anti-leukemic drugs. However, the molecular mechanism for chemoresistance by hypoxia is not fully understood. Methods: In the present study, we investigated the effect of hypoxia on resistance to two therapies, methotrexate (MTX) and prednisolone (PRD), in two cell models for acute lymphoblastic leukemia (ALL). To look for an implication of hypoxia in chemoresistance, cell viability, total cell density and cell proliferation were analyzed. Survival and death signaling pathways were also screened by reverse phase protein array (RPPA) and western blotting experiments conducted on selected proteins to confirm the results. Results: We found that hypoxia promotes chemoresistance in both ALL cell lines. The induction of drug-resistance by hypoxia was not associated with an increase in total cell density nor an increase in cell proliferation.

4Discussion. This study addressed the question of which are the cellular processes that sensitive leukemic cells induced to achieve tolerance to vincristine. To this end, the B-ALL cell line CCRF-SB was gradually exposed until cell proliferation was observed in the presence of 6nM vincristine, and the corresponding proteomic profile was compared to that of cells grown in the absence of the chemotherapeutic drug.. Chemoresistance may be intrinsic or acquired.18 The ability to tolerate high concentrations of chemotherapeutics of an intrinsically resistant cancer cell is not developed as a result of an exposition to the drugs; instead it is the result of genetic abnormalities the cell carries before exposition.18 By contrast, acquired chemoresistance is developed after the cancer cell is exposed to the drug and may be the result of molecular evolution of resistant clones.19 Experimental settings to study acquired chemoresistance include the comparison of matched paired samples at diagnosis and ...

Relapse of childhood acute lymphoblastic leukaemia (ALL) involving the eye is a rare but challenging problem. Twenty cases occurred in patients treated on the Medical Research Council United Kingdom Acute Lymphoblastic Leukaemia XI and ALL97 trials between 1991 and 2001, representing 2.2% of ALL relapses. Seventeen occurred as a first relapse, either in isolation or combined with relapse at another site, and three occurred as a second relapse. All patients with intraocular disease at first relapse were treated with both chemotherapy and radiotherapy, but the doses and protocols used varied. Eleven of these 17 patients are alive and in complete remission with a median follow up of 4 years 2 months from relapse. All 11 children that were treated with a full chemotherapy relapse protocol, together with local radiotherapy have survived. Patients treated with chemotherapy of shorter duration and intensity, despite radiotherapy and/or bone marrow transplantation, did poorly with only one survivor, ...

Background: Chronic lymphocytic leukaemia (CLL) is the most common type of leukaemia in the Western countries. Typically, it is a slowly progressing disease, and treatment by cytostatics is initiated after follow-up in a situation where the patient has an aggressive disease or develops general symptoms. The major obstacle in treatment is drug resistance and, moreover, multidrug resistance. Extensive research into the mechanisms or prognostic factors for chemo- or irradiation resistance has produced few clinically encouraging results. Aims: To evaluate (I) multidrug resistance in CLL and to define the impact of (I) previous chemotherapy, (II) surface antigens, (III) the mutation status of the immunoglobulin variable region (IgHV) genes as well as (IV) programmed cell death, apoptosis, associated gene transcripts in drug and irradiation resistance in CLL.. Material and methods: Peripheral blood samples from a cohort of 36 CLL patients were collected and mononuclear cells, containing mainly CLL ...
Chronic Lymphocytic Leukaemia (CLL) is the most common leukaemia in adults in the US and most of Western Europe. Many patients suffering from CLL have tumour cells expressing high amounts of Bcl-2 protein. Since over expression of Bcl-2 inhibits apoptosis, it is possible that this gene participates in the pathogenesis of CLL. By lowering the Bcl-2 protein in these tumour cells the cells may go into apoptosis due to changed balance in pro- and anti apoptotic proteins and thereby it might be possible to induce a tumour response.. The study is an open-labelled, international, multicenter, dose escalating phase I/II study where patients receive 6, 3, 2 or 1 dose(s) of SPC2996, a LNA antisense molecule against Bcl-2, over a period of up to 2 weeks, and are followed for 6 months. ...

Bleeding events have been observed among a subgroup of chronic lymphocytic leukaemia (CLL) patients treated with ibrutinib. We analysed data from two studies of single-agent ibrutinib to better characterize bleeding events and pattern of anticoagulation and antiplatelet use. Among 327 ibrutinib-treated patients, concomitant anticoagulation (11%) or antiplatelet use (34%) was common, but major bleeding was infrequent (2%). Bleeding events were primarily grade 1, and infrequently (1%) led to discontinuation. Among 175 patients receiving concomitant anticoagulant or antiplatelet agents, 5 had major bleeding events (3%). These events were typically observed in conjunction with other factors, such as coexisting medical conditions and/or concurrent medications ...

BACKGROUND: Chimeric antigen receptor (CAR) modified T cells targeting CD19 have shown activity in case series of patients with acute and chronic lymphocytic leukaemia and B-cell lymphomas, but feasibility, toxicity, and response rates of consecutively enrolled patients treated with a consistent regimen and assessed on an intention-to-treat basis have not been reported. We aimed to define feasibility, toxicity, maximum tolerated dose, response rate, and biological correlates of response in children and young adults with refractory B-cell malignancies treated with CD19-CAR T cells.. METHODS: This phase 1, dose-escalation trial consecutively enrolled children and young adults (aged 1-30 years) with relapsed or refractory acute lymphoblastic leukaemia or non-Hodgkin lymphoma. Autologous T cells were engineered via an 11-day manufacturing process to express a CD19-CAR incorporating an anti-CD19 single-chain variable fragment plus TCR zeta and CD28 signalling domains. All patients received ...
Its the most common type of childhood cancer. The abnormal lymphoblasts grow quickly and replace normal cells in the bone marrow. Acute lymphoblastic leukemia (ALL) happens when the body makes too many lymphoblasts (a type of white blood cell). This article focuses on the Acute lymphoblastic leukemia (ALL) type of leukemia. Acute Lymphoblastic Leukemia. Chemotherapy is the main treatment. It usually needs to be treated as soon as possible after diagnosis. It is commonly seen in adults aged over 55-60 years. ALL is the most common type of childhood cancer, accounting for 35% of all cancers in children. Acute lymphoblastic leukaemia (ALL) is a type of blood cancer. Acute Lymphoblastic Leukemia or ALL, is a cancer that affects the bone marrow. However, the ability to dissect these evolving, heterogeneous interactions among distinct B-ALL subtypes and their varying BM niches is limited with current in vivo methods. Acute lymphocytic leukemia (ALL) is a cancer of the blood and bone marrow. This type ...
Manufacturer: Amgen. The antibody is a bispecific T-cell engager that binds to CD19 on the surface of cells in B-lineage origin and CD3 expressed on the surface of T-cells. Blinatumomab activates endogenous T-cells by connecting to CD3 in the T-cell receptor complex with CD19 on benign and malignant B-cells. The formation of a cytolytic synapse between the T-cell and the tumour cell causes the release of proteolytic enzymes, which kills both proliferating and resting target cells.. Patients may receive 2 cycles of treatment. A single cycle of treatment is 4 weeks of continuous infusion. followed by a 2-week treatment-free interval. Patients who have achieved complete remission after 2 treatment cycles may receive up to 3 additional cycles of blinatumomab treatment, based on an individual risk-benefit assessment.. ...
Previous studies have shown that the pattern of response to B-cell receptor (BCR) engagement in B-CLL is highly correlated with cellular levels of the lymphoid oncogene TCL1 and with the formation of activation complexes at the BCR that include TCL1, Akt, and membrane-proximal tyrosine kinases such as ZAP70. The CLL cases with high TCL1 also showed more aggressive growth features in vivo, including advanced clinical stage, higher white blood cell counts, shorter lymphocyte doubling time, and poor response to all therapy types, with TCL1 levels as an independent predictor of outcome in multivariate models (5, 6).. Although little doubt exists on the link between Nutlin-3-mediated transcriptional activity of p53 and cell-cycle arrest mediated by p21, some recent studies have provided evidence for a transcription-independent induction of apoptosis by Nutlin-3 (20-22, 30, 31). In particular, these studies have shown that the transcription-independent mitochondrial p53 program plays an important role ...
Australian Medicines Handbook section 14.1.3 Acute lymphocytic leukaemia is the most common childhood malignancy. Although chemotherapy has improved survival, many children have a high risk of relapse. As chemotherapy can be ineffective in relapsed disease there is a need for new therapies. Clofarabine is a purine nucleoside analogue. It has structural similarities to the purine antagonists cladribine and fludarabine. After dilution and slow intravenous infusion, clofarabine is converted intracellularly to a metabolite which inhibits DNA synthesis and induces apoptosis. There is little hepatic metabolism with 50-60% of the dose being excreted unchanged in the urine. The terminal half-life is approximately five hours. The approval of clofarabine is based on a phase II study of 61 people whose acute lymphocytic leukaemia was refractory or had relapsed at least twice. Their ages ranged from 1 to 20 years with a median of 12 years. Clofarabine was infused for five consecutive days every 2-6 weeks ...

The microvessel density (MVD) was assessed in lymph nodes infiltrated by diffuse large B-cell lymphomas, mantle cell lymphomas, chronic lymphatic leukemia and follicular lymphomas, and in lymphadenitis. Serial sections of formalin-fixed and paraffin-embedded tissue were stained with antibodies against CD31, CD34 or Factor VIII. Using light microscopy and computerised image analysis, the number and size of individual immunostained vessel profiles within a preselected area size range corresponding to capillaries, postcapillary venules, small collecting venules and small arterioles were determined. A significantly larger number of vessels were registered following staining with anti-CD34 than with anti-CD31 or anti-Factor VIII. Moreover, among the smallest capillary-sized vessel profiles in all lesion types, there was a selective relative loss of stainability of anti-CD31 and anti-Factor VIII, resulting in a substantial total loss of visualised capillary-sized vessels compared with anti-CD34. In ...

BACKGROUND: The effects on long-term outcome in childhood acute lymphoblastic leukaemia (ALL) of the duration and the intensity of maintenance chemotherapy need to be assessed reliably. With this objective the Childhood ALL Collaborative Group coordinated a worldwide overview of all randomised trials that began before 1987. METHODS: Individual patient data were sought for about 3900 children in trials of longer vs shorter maintenance (eg, 3 vs 2 years), 3700 in trials of intensive reinduction chemotherapy during maintenance, and 4400 in trials of various other questions, including 1300 in trials of pulses of vincristine and prednisone (VP) during maintenance. Analyses were of survival in first remission, overall survival, and cause-specific mortality. FINDINGS: Deaths during remission were increased by longer maintenance (2.7 percent vs 1.2 percent), VP pulses (4.0 vs 3.2 percent), and intensive reinduction (4.8 percent vs 3.3 percent), but these increases were counterbalanced by reductions in
Normal and aberrant immune receptor gene assembly each produce site-specific DNA rearrangements in leukemic lymphoblasts. In either case, these rearrangements provide useful clonal markers for the leukemias in question. In the t(1;14)(p34;q11) translocation associated with T cell acute lymphoblastic leukemia (T-ALL), the breakpoints on chromosome 1 interrupt the tal-1 gene. A site-specific deletion interrupts the same gene in an additional 26% of T-ALL. Thus, nearly one-third of these leukemias contain clustered rearrangements of the tal-1 locus. To test whether these rearrangements can serve as markers for residual disease, we monitored four patients with T-ALL; three of the leukemias contained a deleted (tald) and one a translocated (talt) tal-1 allele. These alleles were recognized by a sensitive amplification/hybridization assay. tald alleles were found in the blood of one patient during the 4th mo of treatment but not thereafter. Using a quantitative assay to measure the fraction of tald ...
BackgroundSomatic genetic abnormalities are key initiators and drivers of disease in acute lymphoblastic leukaemia (ALL). Several chromosomal abnormalities have proven clinical utility as prognostic and predictive biomarkers at initial diagnosis. However, the role of genetic biomarkers in relapsed ALL is less well understood and has rarely been studied comprehensively within a clinical trial.AimsTo evaluate the role of genetics in predicting outcome among children with relapsed B-cell precursor ALL treated on the international trial, ALLR3.MethodsWe analysed cytogenetic, copy number alteration (CNA) and sequence mutation data at relapse in representative cohorts of patients. Patients with a very early relapse (,18 months from first diagnosis) and those patients with an isolated marrow relapse who had an early relapse (,6 months from stopping frontline therapy) were treated as clinical high risk (HR) whereas all other patients were treated as clinical standard risk (SR).ResultsClinical HR ...
Acute lymphoblastic leukaemia (ALL) is a heterogeneous disease of different immuno-phenotypically defined subtypes. Although successful conventional therapies are available, for a proportion of patients (approximately 30%) these are ultimately unsuccessful. ALL relapse is a result of the failure of the immune system to recognise these malignant cells and down regulation of crucial molecules required for cognate CD4+ T-cell recognition has been postulated as a means of immune escape. This study has concentrated on the augmentation of the immunogenicity of B-cell ALL to facilitate the generation of an anti-leukaemic immune response.;The initial gene therapy approach to enhancing ALL immunogenicity relied upon the successful transfection of primary ALL cells with a range of constructs carrying immunomodulatory genes, and the development of a protocol to routinely establish ALL cell lines from primary cultures, thus enabling the use of low-yield transfection systems to introduce recombinant DNA ...

Acute Lymphocytic Leukemia What is acute lymphocytic leukemia? Acute lymphocytic leukemia (ALL) is a cancer of the blood in which too many lymphocytes, a type of white blood cell, are produced by the bone marrow and by organs of the lymph system. Normally, the lymphocytes fight infection. But, in ALL, the cells are immature and overabundant. They crowd out other blood cells, and may collect in the blood, bone marrow, and lymph tissue. Acute leukemia can occur over a short period of days to weeks. Chromo...

ZAP70 gene expression is associated with poor prognosis in B-cell lymphoproliferative disorders especially chronic lymphocytic leukaemia (CLL) but its role in adult B-ALL has not been established. On diagnostic samples from 76 patients with adult ALL (65 with B-ALL and 11 with T-ALL) ZAP70 mRNA expression levels were studied by real time-quantitative PCR (RT-qPCR) analysis. A broad distribution of ZAP70 expression was observed in ALL, ranging from 0.002 to 5.3 fold that of the ZAP70 positive Jurkat reference cell line. No association was observed between expression levels and the presence of specific cytogenetic abnormalities. Five cases, including one case of T-ALL, had ZAP70 expression above the level of the Jurkat reference cell line. Our results confirm the frequent expression of ZAP70 in adult ALL. Limited comparisons made did highlight poor-risk patients with high ZAP70 expression, but due to lack of clinical information on patient samples we were unable to directly assess the impact on disease
