One of the major problems in treatment of leukemias is multidrug resistance, which is already present at diagnosis or develops after chemotherapy. The gene expression levels of multidrug resistance resistance 1 (MDR1), breast cancer resistance protein (BCRP) and lung resistance-resistance protein (LRP) were evaluated in blood samples of 20 CLL and 24 CML patients using RT-PCR. MDR1, BCRP and LRP expression levels were detected in 65%, 20% and 45% of CLL patients, and in 54%, 37% and 25% of CML patients, respectively. 20% of CLL patients and 33% of CML patients expressed none of the genes. The other 20% of CLL patients expressed all the genes. 17% of CML patients expressed all of these genes, and two of them rapidly progressed to acute leukemia. MDR and LRP expressions seem to be frequent events in CLL and CML patients; however no conclusion can be drawn on their prognostic role and response to the treatment.

Effect of cobalt-60 (gamma radiation) on multidrug-resistant multiple myeloma cell lines Mutlu, Pelin; Ural, A. Ugur; Avcu, Ferit; Dirican, Bahar; Beyzadeoglu, Murat; Gündüz, Ufuk (2011-07-01) Emergence of resistance to chemotherapy and radiotherapy is a major obstacle for the successful treatment of MM (multiple myeloma). Prednisone, vincristine and melphalan are commonly used chemotherapeutic agents for the treatment of MM. In the current study, we examined the presence of possible cross-resistance between these drugs and gamma (gamma) radiation. Prednisone, vincristine and melphalan resistant RPMI-8226 and U-266 MM cells were generated by stepwise increasing concentrations of the drugs. The se...
Effect of MDR modulators verapamil and promethazine on gene expression levels of MDR1 and MRP1 in doxorubicin-resistant MCF-7 cells Donmez, Yaprak; Akhmetova, Laila; Iseri, Ozlem Darcansoy; Kars, Meltem Demirel; Gündüz, Ufuk (2011-04-01) One of the major problems of cancer chemotherapy is the development of multidrug resistance (MDR) phenotype. Among the numerous mechanisms of MDR, a prominent one is the increased expression of membrane transporter proteins, the action of which leads to decreased intracellular drug concentration and cytotoxicity of drugs. Among them, P-gp and MRP1, encoded by MDR1 and MRP1 genes, respectively, have been associated with MDR phenotype. Chemical modulators can be used to reverse MDR. These chemicals can either...
Interaction of tomato lectin with ABC transporter in cancer cells: Glycosylation confers functional conformation of P-gp Molnar, Joseph; Kars, Meltem Demirel; Gündüz, Ufuk; Engi, Helga; Schumacher, Udo; Van Damme, Els J.; Peumans, Willy J.; Makovitzky, Josef; Gyemant, Nora; Molnar, Peter (2009-01-01) Phospho-glycoprotein (P-gP) is a polytopic plasma membrane protein whose overexpression causes multidrug resistance (MDR) responsible for the failure of cancer chemotherapy. P-gp 170 is a member of the ATP-binding cassette (ABC) transporter superfamily and has two potentially interesting regions for drugs interfering with its efflux function, namely the oligosaccharides on the first extracellular loop with unknown function and the two intracellular ATP-binding regions providing the energy for drug efflux fu...
Expression analysis of TOP2A, MSH2 and MLH1 genes in MCF7 cells at different levels of etoposide resistance Kaplan, Esra; Gündüz, Ufuk (2012-02-01) Purpose: Development of resistance against anti-cancer drugs is one of the major obstacles of chemotherapy in the treatment of cancer. Etoposide is a topoisomerase II alpha (TOP2A) inhibitor, which is used in the treatment of breast cancer. Alterations in the expression of drug targets or DNA repair genes are among the important resistance mechanisms against TOP2A inhibitors. In this study, expression changes in TOP2A gene and two important mismatch repair (MMR) genes MSH2 and MLH1 were examined in order to...
Reversal of multidrug resistance in mcf-7 breast adenocarcinoma cell line by silencing interleukin 6 with RNA interference Çakmak, Neşe; Gündüz, Ufuk; Department of Biology (2013) Multidrug resistance (MDR) in cancer is characterized by development of resistance to several unrelated drugs upon long time administration of a certain type of chemotherapeutic agent. In doxorubicin resistant MCF-7 cell line, resistance is developed mainly by upregulation of MDR1 gene which encodes an ABC transporter protein known as P-glycoprotein. Interleukin 6 (IL-6) is a cytokine which acts as a growth factor for certain cell types including some cancer cells. IL-6 is found at high levels in cancer pat...
