Several diseases, such as sickle cell disease and cancer, can affect the properties of cells. Manipulation or separation of the altered cell is necessary to diagnose such diseases. Acoustophoresis, the migration of particles by using acoustic standing waves, is a promising technique for bio-particle manipulation. This thesis presents numerical modelling and experimental investigation of using acoustophoresis for cell manipulation purposes. First, the trajectories of the cells in an acoustophoretic chip are calculated using an acousto-mechanical numerical model that includes elastic modelling of cells. For experimental investigations, two different types of chip architecture are discussed. Using the first architecture, the capabilities of different chip materials for acoustic manipulation have been assessed by conducting thermal, vibration, focusing, and viability experiments. Then, a two-layered chip is introduced as a second architecture for bacteria and WBC separation purposes.

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,...
Effects of novel compound derived from vitamin e on prostate cancer cell line
Ergen, Nuri; Severcan, Feride; Department of Biology (2016)
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 pro...
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...
Microarray applications for determination of the effects of emodin on breast cancer cell lines
Ekenel Qomi, Emilia; İşcan, Mesude; Çoruh, Nursen; Department of Biotechnology (2011)
Cancer is a genetic disease that is characterized by uncontrolled cells growth. Breast cancer is a type of cancer originating from breast tissue. Some breast cancers are sensitive to hormones such as estrogen which makes it possible to treat them by blocking the effects of these hormones in the target tissues. These require less aggressive treatment than hormone negative cancers. Breast cancers without hormone receptors, are higher-risk, and are treated more aggressively. The aim of our study is to investig...
Epigenetic Mechanisms Underlying the Dynamic Expression of Cancer-Testis Genes, PAGE2, -2B and SPANX-B, during Mesenchymal-to-Epithelial Transition
Yilmaz-Ozcan, Sinem; Sade, Asli; Kucukkaraduman, Baris; Kaygusuz, Yasemin; Senses, Kerem Mert; Banerjee, Sreeparna; GÜRE, ALİ OSMAY (Public Library of Science (PLoS), 2014-09-17)
Cancer-testis (CT) genes are expressed in various cancers but not in normal tissues other than in cells of the germline. Although DNA demethylation of promoter-proximal CpGs of CT genes is linked to their expression in cancer, the mechanisms leading to demethylation are unknown. To elucidate such mechanisms we chose to study the Caco-2 colorectal cancer cell line during the course of its spontaneous differentiation in vitro, as we found CT genes, in particular PAGE2, -2B and SPANX-B, to be up-regulated duri...
