Wayne State University Dissertations

Atomic Force Microscopy (AFM) provides superior imaging resolution and the ability to measure forces at the nanoscale. It is an important tool for studying a wide range of bio-molecular samples from proteins, DNA to living cells. We developed AFM measurement procedures to measure protein interactions on live cells at the single molecular level. These measurements can be interpreted by using proper statistical approaches and can yield important parameters about ligand-receptor interactions on live cells. However, the standard theory for analyzing rupture force data does not fit the experimental rupture force histograms. Most of the experimental measurements of rupture force data …

Ovarian Cancer is the fifth leading cause of cancer-related death of women in the United States. Epithelial Ovarian Cancer (EOC) constitutes 85-90% of malignancies within the ovary, with an alarming majority of these cases diagnosed at advanced stage. While most patients are initially highly responsive to the current treatment standard, there is a very high probability that they will recur with a drug resistant fatal disease. Currently there is no validated comprehensive model of disease progression for ovarian cancer, although tremendous progress has been made in understanding the origin of this disease and a putative precursor lesion has been identified …
