Cancer is a complex disease characterized by uncontrolled cell proliferation, invasion and metastasis. It is known that vitamins having high antioxidant capacity, like vitamin A, C and E, play important roles in adjuvant therapy and as cancer protective agents. Vitamin E is a group of fat soluble antioxidant nutrients consisting of tocopherols and tocotrienols. Various research has been performed on the utility of vitamin E derivatives on cancer treatment. Energy metabolism of cells alters during cancer progression due to the increased energy need of cells. Changes in fatty acid, phospholipid and triglyceride amounts in cancer cells were reported in previous studies. Prostate cancer cells, which are regulated by the lipid derivative molecules like androgen have remarkable changes in lipid metabolism. A novel vitamin E derived compound, which has modification on the side chain, was used in this study in order to reveal its roles on cancer progression and cancer lipid metabolism. Based on several experiments performed in this study, it has been concluded that alpha tocopherol derived compound had less toxicity to normal prostate epithelium and compound treatment caused reduction in proliferation and increase in apoptosis of the prostate cancer cell line LNCaP by causing mitochondrial membrane depolarization. Also, cells treated with the novel compound had a remarkable reduction in their motility and migration capacity implying anti metastatic activity and compound treatment led to alterations on lipid metabolism which were detected at both spectroscopic and protein, mRNA levels. Additionally, cells treated with compound show decreased lipid peroxidation as well as increased lipid order that leads to changes in cellular membrane structure. These properties of alpha tocopherol derived compound emphasize the importance of this molecule as a possible therapeutic option in prostate carcinogenesis.

Effect of cisplatin-metformin drug combination on GSTP1 mediated apoptosis
Durukan, Özlem; Arslan, Şevki; Adalı, Orhan (null; 2017-09-08)
Kllng cancer cells by trggerng cellular apoptoss seems to be the prevalent acton mechansm for cancer drugs. Usng substances that targetng the enzymes partcpatng n the apoptotc pathways that trggers the cellular apoptoss can be a useful treatment opton for cancer. GSTP enzyme, ts newly known role as a modulator of cellular survval and death, can be a good proten molecule for cancer studes. Although, csplatn as one of the most potent alkylatng agent that appled wth success n vast majorty of cancers, ts sde ef...
Analysis of 3'UTR shortening events in breast cancer
Baloğlu, Onur; Can, Tolga; Department of Bioinformatics (2013)
Cancer is the collective term used to describe a diverse group of diseases that share certain hallmarks, which in turn enables the affected cells to sustain an uncontrolled cell growth. Despite the increasing efforts and advances in cancer therapies, cancers are still responsible for approximately 10% of all the deaths worldwide. Furthermore, the increase in the average human lifespan will further contribute to the cancer incidences. This brings the necessity to focus our efforts on early detection and effe...
Identification of rare cell types in lung cancer and investigation of their use in prognosis
Yıldız, Cemal; Şengül Babal, Simge; Pir, Pınar (Orta Doğu Teknik Üniversitesi Enformatik Enstitüsü; 2022-10)
Cancer is a complex, dynamic and heterogeneous disease. Identification of tumor heterogeneity holds a significant promise not only on tumor classification but also on predicting the prognosis and choosing the right treatment. Therefore, it is essential to investigate tumor heterogeneity in a regular diagnosis procedure. Tumors contain variety of cell types such as malignant cells, non-malignant cells, immune cells, and rare cells (i.e., dormant cells (DRM) and cancer stem cells (CSC))....
Synthesis of poly (dl-lactic-co-glycolic acid) coated magnetic nanoparticles for anti-cancer drug delivery
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...
Reversal of breast cancer resistance protein mediated multidrug resistance in MCF7 breast adenocarcinoma cell line
Urfalı, Çağrı; Gündüz, Ufuk; Department of Biology (2011)
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, the...
