Resistance to various chemotherapeutic agents is a major problem in success of cancer chemotherapy. One of the primary reasons of development of multidrug resistance (MDR) is the overexpression of ATP binding cassette (ABC) transporter proteins. Breast cancer resistance protein (BCRP) belongs to ABC transporter family and encoded by ABCG2 gene. BCRP is mainly expressed in MDR1 (P-glycoprotein) lacking breast cancer cells. Overexpression of BCRP leads to efflux of chemotherapeutic agents at higher rates, therefore, decreased levels of intracellular drug accumulation. Despite the fact that several chemical modulators claim to restore BCRP-mediated increased drug efflux, these modulators were shown to display various side effects, precluding their clinical use. Therefore, to reverse BCRPmediated MDR phenotype by a modulator with minimum cytotoxicity may increase clinical benefits and minimize side effects.

Tansık, Gülistan; Gündüz, Ufuk; Department of Biology (2012)
One of the main problems of current cancer chemotherapy is the lack of selectivity of anti-cancer drugs to tumor cells which leads to systemic toxicity and adverse side effects. In order to overcome these limitations, researches on controlled drug delivery systems have gained much attention. Nanoscale based drug delivery systems provide tumor targeting. Among many types of nanocarriers, superparamagnetic nanoparticles with their biocompatible polymer coatings can be targeted to an intented site by an extern...
The role of 15-LOX-1 in resistance to chemotherapeutics
Kazan, Hasan Hüseyin; Gündüz, Ufuk; Department of Biology (2020)
Chemotherapy is one of the best options to treat cancer. However, drug resistance can limit the efficacy of chemotherapeutics. There have been several reasons for the cancer drug resistance including the export of the drug from cells, inactivation of drugs by enzymatic processes, mutations that limit the binding of the drugs to the target proteins, resistance to cell death mechanism by cellular manipulations and reorganization of the cell membrane. 15-Lipoxygenase-1 (15-LOX-1) is a member of the lipoxygenas...
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...
Investigaton of chemopreventive properties of Urtica Dioica L., in MCF-7 and MDA231 breast cancer cell lines
Güler, Elif; İşcan, Mesude; Department of Biology (2011)
Cancer is a major health problem in developing world with mostly unsufficient treatment. Cancer prevention through dietary modification appears to be a practical and cost effective possibility. The aim of present study is to investigate the chemical components of “Urtica diocia,L (U. diocia) grown in Turkey” and the possible protective potential of its aqueous extract against breast cancer cell lines. U. diocia was extracted by maceration method which was performed for 6,12, 24, and 36 hours, at 50°C, 37°C,...
