Examination Of Promotor Hypermethylation Patterns In Magnetically Enriched Exfoliated Breast Milk Epithelial Cells, Chung M. Wong

Masters Theses 1911 - February 2014

Suppression of genes involved in DNA repair, tumor suppression and detoxification through epigenetic modifications has been implicated in the etiology of cancer. As such analysis of promoter methylation patterns in genes frequently down regulated in breast cancer in non-cancerous subjects may serve as an indicator of breast cancer risk. CpG-island hypermethylation of single genes has been detected in cells isolated from nipple aspirate and ductal lavage, yet both isolation methods yield insufficient cells to complete an extensive analysis on any one donor sample.

As an alternative we have turned to magnetic separation of human mammary epithelial cells from breast milk. …

Anti-Diabetic Potentials Of Phenolic Enriched Chilean Potato And Select Herbs Of Apiaceae And Lamiaceae Families, Fahad Saleem

Masters Theses 1911 - February 2014

The incidence of diabetes mellitus and cardiovascular diseases is increasing at a worrisome rate globally. Diabetes mellitus is known to occur due to high blood glucose levels, caused by defects in insulin levels. Adult on-set type II diabetes, which is closely associated with obesity, is reported to be 90-95% of all diabetic cases and linked to diet and lifestyle factors. A large population of the developed and developing countries is now being effected by this epidemic. Natural sources of phenolic antioxidants and inhibitors of digestive enzymes from food sources have potential for low cost dietary management of type II diabetes. …

In Vivo Labeling Of A Model Β-Clam Protein With A Fluorescent Amino Acid, Mangayarkarasi Periasamy

Masters Theses 1911 - February 2014

Proteins can be labeled with different tags to enable their structural and functional investigations. In addition, labeling proteins at specific sites helps in studying the conformational dynamics of these molecules. A plethora of methods is available to facilitate labeling, choice of which largely depends on the requirements and the anticipated end results. In general, the various labeling methods can be classified into four different classes based on the stage at which labeling is performed, namely post translational labeling, non-ribosomal synthesis, in vitro translation and in vivo translation. Interestingly all these techniques use different unnatural amino acids for this purpose.
