  1. 1. Pharmacology and resistance mechanisms of nucleoside analogues and topoisomerase II interactive agents : studies on human leukemia cells with a focus on cross-resistance

    Författare :Kourosh Lotfi; Rolf Larsson; Linköpings universitet; []
    Nyckelord :Nucleoside analogue; cross-resistance; multidrug resistance; deoxycytidine kinase; leukemia; anthracyclines; P-glycoprotein; MEDICINE; MEDICIN;

    Sammanfattning : The purpose of this thesis was to elucidate mechanisms of action and resistance of clinically relevant nucleoside analogues and topoisomerase interactive agents in human leukemia cell lines and leukernia cells isolated from peripheral blood of leukemia patients. Interactions and cross-resistance patterns of these different cytotoxic drug families were also studied since these drugs are usually administrated in combination in the clinic. LÄS MER

  2. 2. Health-related quality of life during and after stem cell transplantation

    Författare :Ulla Frödin; Sussanne Börjeson; Kourosh Lotfi; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Hematopoietic stem cell transplantation (HSCT) is an established treatment for a variety of malignant diseases, as well as a small proportion of non-malignant disorders. The treatment before the HSCT (called conditioning) can be either myeloablative (MAC) or given with reduced intensity (RIC). LÄS MER

  3. 3. Nucleoside analoge cytotoxicity-focus on enzyme regulation, metabolism, and mechanisms of resistance

    Författare :Anna Fyrberg; Kourosh Lotfi; Curt Peterson; Freidoun Albertioni; Francoise Bontemps; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; Farmakologi;

    Sammanfattning : The aim of this thesis was to determine the role of nucleoside analog activating and deactivating enzymes in nucleoside analog metabolism and resistance development. Nucleoside analogs are anti-cancer drogs and are often used to treat different leukemias, attributably to presence of high levels of nucleoside analog activating enzymes in hematopoietic cells.

  4. 4. Prognostic markers in acute myeloid leukemia : A candidate gene approach

    Författare :Ingrid Jakobsen; Kourosh Lotfi; Henrik Gréen; Anna Fyrberg; Christian Thiede; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The standard treatment of acute myeloid leukemia (AML) consists of induction chemotherapy, most commonly daunorubicin together with the nucleoside analogue cytarabine (Ara-C), followed by consolidation chemotherapy and in selected cases allogenic stem cell transplantation (allo-SCT). Despite a high initial response rate, a considerable proportion of all AML cases eventually suffer from relapse and the five-year overall survival rate in patients >60 years is only around 15%.

  5. 5. Influence of CYP3A enzymes and ABC transporters on the activity of tyrosine kinase inhibitors in chronic myeloid leukemia

    Författare :Karin Skoglund; Henrik Gréen; Curt Peterson; Kourosh Lotfi; Staffan Hägg; Jörg Cammenga; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The introduction of imatinib, a tyrosine kinase inhibitor (TKI), in the treatment of chronic myeloid leukemia (CML) was a major break-through and the first drug that was successfully designed to target the specific mechanism of a malignant disease. Imatinib still remains as the standard treatment of newly diagnosed CML patients although a second generation of TKIs has also been approved for first-line CML treatment. LÄS MER
