Writing and defending a thesis is the culminating experience for Georgia State University students in the philosophy M.A. program. In their thesis, students develop a piece of their philosophical writing, creating multiple drafts in response to comments from a variety of philosophical viewpoints, and then orally defend their thesis in nietzsche’s philosophy a thesis submitted to the graduate school of social sciences of middle east technical university by bİlge akbalik in partial fulfillment of the requirements for the degree of master of arts in department of philosophy december This thesis was prepared under the direction of the candidate’s thesis advisor, Dr. Clevis Headley, Department of Philosophy, and has been approved by the members of his supervisory committee. It was submitted to the faculty of the Department of Philosophy and was accepted in

The premature fusion of these sutures, known as craniosynostosis, is a common developmental abnormality and has been extensively utilised here as a tool through which to study the genetics of suture morphogenesis and craniofacial diversity.
Investigations began with a search for polymorphisms associated with normal variation in human craniofacial characteristics. Denaturing High-Performance Liquid chromatography was used to identify polymorphisms in two genes causative for craniosynostosis by analysing DNA from a large cohort of individuals from four ethnogeographic populations.
A single nucleotide polymorphism in fibroblast growth factor receptor 1 was identified as being associated with variation in the cephalic index, a common measure of cranial shape.
Two approaches, both utilising Affymetrix gene expression microarrays, were used to identify genes differentially expressed during premature suture fusion, thesis philosophy pdf. The first was a novel method which utilised the observation that explant cells from both fused and unfused suture tissue, cultured in minimal medium, produce a gene expression profile characteristic of minimally differentiated osteoblastic cells.
Consequently, gene expression was compared between prematurely fused suture tissues and their corresponding in vitro de-differentiated cells. In thesis philosophy pdf to those genes known to be involved in suture morphogenesis, a large number of novel genes were identified which were up-regulated in the differentiated in vivo state and are thus implicated in premature suture fusion and in vivo osteoblast differentiation.
Again, both known genes and a substantially large number of novel genes were identified as being differentially expressed. Some of these novel genes included retinol binding protein 4 RBP4thesis philosophy pdf, glypican 3 GPC3 thesis philosophy pdf, C1q tumour necrosis factor 3 C1QTNF3and WNT inhibitory factor 1 WIF1. The known functions of these genes are suggestive of potential roles in suture morphogenesis.
RBP4 was found to be localised on the thesis philosophy pdf surface of unfused sutures and in cells lining the osteogenic fronts while GPC3 was localised to suture mesenchyme of unfused sutures. A comparison between each unfused suture coronal, sagittal, metopic, and lambdoid demonstrated that gene expression thesis philosophy pdf are suture-specific which, based on the identification of differentially expressed genes, suggests possible molecular bases for the differential timing of normal fusion and the response of each suture to different craniosynostosis mutations.
One observation of particular interest was the presence of cartilage in unfused lambdoid sutures, suggesting a role for chondrogenesis in posterior skull sutures which have generally been thought to develop by intramembranous ossification without a cartilage precursor.
Finally, the effects of common media supplements used in in vitro experiments to stimulate differentiation of calvarial suture-derived cells were investigated with respect to their ability to induce in vivo-like gene expression.
Both media induced collagen matrix and bone nodule formation indicative of differentiating osteoblasts. However, the genes expression profiles induced by both media differed and neither recapitulated the levels and profiles of gene expression observed in vivo for cells isolated from both fused and unfused suture tissues.
This study has implications for translating results from in vitro work to the in vivo situation. Significantly, the de- thesis philosophy pdf microarray study identified differentially expressed genes whose products may be thesis philosophy pdf candidates as more appropriate osteogenic supplements that may be used during in vitro experiments to better induce in vivo-like osteoblast differentiation.
This study has made a substantial contribution to the identification of novel genes and pathways involved in controlling human suture morphogenesis and craniofacial diversity. The results from this research will stimulate new areas of inquiry which will one day aid in the development of better diagnostics and therapeutics for craniosynostosis, and other craniofacial and more general skeletal abnormalities.

Anna Coussens Date:………………………………. These are the people who stuck by me and helped in anyway they could to ensure that I finished and that I made it to Africa on time! Firstly to Ian. There are no words to describe how thankful I am to you. Although you only took on the supervisory role in an official manner halfway though this year, the extent of your support and guidance extended long before that.
There is no way I would have made it to this point without you, and many of the ideas thesis philosophy pdf we had would never have come to fruition.
