Resistance mechanisms developed against chemotherapeutic drugs limits success in chemotherapy. Making the drug resistant cells re-sensitive to the chemotherapeutic agents is extremely important for the treatment. Various compounds obtained from plants have been found to prevent the anticancer drug efflux from the cells. In the present study, the effect of Nerium oleander distillate on paclitaxel and vincristine resistant (MCF-7/Pac, MCF-7/Vinc) and sensitive MCF-7 cell lines has been investigated. Nerium oleander leaf extract was obtained by hydrodistillation method. The total plant phenolic composition and content of distillate were determined by HPLC and Folin's assay. The effect of distillate on cells was evaluated by XTT tests. The MDR reversal activity of the plant distillates will further be determined by fluorescent microscopy. The total plant phenolic content was 20 mg GAE/g Nerium oleander distillate. According to XTT tests, Nerium oleander distillate is not cytotoxic for MCF-7/S, MCF-7/Pac and MCF-7/Vinc cells when in vivo concentration applied to animals are considered. To conclude, the distillate has a considerable amount of total plant phenolic content. And, it has effects on the viability of all cell lines only at very high concentrations which may clinically be taken as overdose.


Prediction of enzyme classes in a hierarchical approach by using SPMap
Yaman, A.; Atalay, Mehmet Volkan; Atalay, Rengül (2010-04-01)
Enzymes are proteins that play important roles in biochemical reactions as catalysts. They are classified based on the reaction they catalyzed, in a hierarchical scheme by International Enzyme Commission (EC). This hierarchical scheme is expressed in four-level tree structure and a unique number is assigned to each enzyme class. There are six major classes at the top level according to the reaction they carried out and sub-classes at the lower levels are further specific reactions of these classes. The aim ...

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...
Effects of pulse feeding of beet molasses on recombinant benzaldehyde lyase production by Escherichia coli BL21(DE3)
Çalık, Pınar (Springer Science and Business Media LLC, 2009-11-01)
The effect of fed-batch operation (FBO) strategy was investigated using pretreated-beet molasses, containing galactose that induces the lac promoter, on benzaldehyde lyase (BAL) production by recombinant Escherichia coli BL21(DE3)pLySs. After batch cultivation with 30 g l(-1) pretreated-beet molasses consisting of 7.5 g l(-1) glucose and 7.5 g l(-1) fructose, three FBO strategies were applied at dissolved oxygen (=40%) cascade to air-flow rate. In FBO1 when air-flow rate decreased considerably, feed was giv...
Influence of oxygen transfer on benzaldehyde lyase production by recombinant Escherichia coli BL21(DE3) pLySs
Angardi, Vahideh; Çalık, Pınar; Department of Chemical Engineering (2007)
In this study, the effects of oxygen transfer conditions on the synthesis of the enzyme benzaldehyde lyase as intracellular in recombinant E. coli BL21 (DE3) pLysS was investigated sistematically and a comprehensive model was developed to determine benzaldehyde lyase activity. For this purpose, the research program was carried out in mainly two parts. In the first part of study, the effects of oxygen transfer together with the mass transfer coefficient (KLa), enhancement factor E (=KLa/KLao), volumetric oxy...
Effects of risperidone treatment on the expression of hypothalamic neuropeptide in appetite regulation in Wistar rats
Kursungoz, Canan; AK, MEHMET; Yanık, Tülin (2015-01-30)
Although the use of atypical antipsychotic drugs has been successful in the treatment of schizophrenia, they can cause some complications in the long-term use, including weight gain. Patients using these drugs tend to disrupt treatment primarily due to side effects. The atypical antipsychotic mechanism of action regulates a number of highly disrupted neurotransmitter pathways in the brains of psychotic patients but may also cause impairment of neurohorrnonal pathways in different brain areas. In this study,...
