Single-Fluorophore Sensors For Mechanical Force In Living Cells, Sarah Kricheff
Single-Fluorophore Sensors For Mechanical Force In Living Cells, Sarah Kricheff
Honors Scholar Theses
Mechanotransduction is the process by which a mechanical stimulus is converted to a cellular signal. This process is heavily influential of cell morphology, differentiation, and behavior. However, altered levels of mechanical stimuli are also found in many pathological contexts. For example, cancerous cells have stiffer surrounding tissue than healthy cells, and research suggests that this alters cell behavior and promotes metastasis. Despite these findings, the cellular processes behind these signaling alterations remain widely unknown. Understanding these cascades is critical, as involved proteins can give us a deeper understanding of the role of mechanotransduction, and certain proteins can potentially be targeted …
The Anti-Proliferative Effects Of Methotrexate And Novel Ucp1162 On Acute Myeloid Leukemia Cell Lines, Jacqueline Klepinger, Charles Giardina, Didem Ozcan
The Anti-Proliferative Effects Of Methotrexate And Novel Ucp1162 On Acute Myeloid Leukemia Cell Lines, Jacqueline Klepinger, Charles Giardina, Didem Ozcan
Honors Scholar Theses
Cancer cells proliferate at rapid rates due to the aberrant activity of proteins involved in regulating the cell cycle. This characteristic allows mutated cancer cells to spread and metastasize, causing lesions to form throughout the body. Two treatment conditions, one classical antifolate methotrexate (MTX) and non-classical, novel antifolate UCP1162, were tested on a panel of acute myeloid leukemia (AML) cell lines to determine if UCP1162 has higher anti-proliferative activity. High dose MTX is used as a first line chemotherapy in common childhood malignancies such as acute lymphoid leukemia (ALL). Methotrexate is excluded from acute myeloid leukemia (AML) treatments based on …
Microglia-Neuron Interactions In A Mouse Model Of Low Grade Neuroepithelial Tumors, Veolette Hanna
Microglia-Neuron Interactions In A Mouse Model Of Low Grade Neuroepithelial Tumors, Veolette Hanna
Honors Scholar Theses
Microglia are the macrophages of the brain and spinal cord, playing an important role in the immune response to disease states of the nervous system. This study conducts an investigation on the activity of microglia in response to low grade neuroepithelial tumors. Using mouse models and microglial markers, a qualitative and quantitative analysis of microglia activation, migration, and invasion within the brain cortex during early stages of tumor development was conducted. It was found that the presence of a low grade neuroepithelial tumor in the cortex of one hemisphere of the brain causes significant microglia activation in comparison to the …

Characterization Of A Mycoplasma Pneumoniae Cards Toxin Mutant, Nikaash Pasnoori
Honors Scholar Theses
Mycoplasma pneumoniae is a high-burden pathogen which causes mild to significant infections of the respiratory system. According to the CDC, an estimated two million cases occur yearly in the United States alone, demonstrating the widespread effect of the pathogen. In addition to being the cause of respiratory infections, M. pneumoniae has also been implicated in exacerbating pre-existing asthma conditions. These morbidities make finding a vaccine candidate a vital part of easing the healthcare burden caused by the pathogen. The current mechanism of infection is unknown, but recent evidence points to the Community Acquired Respiratory Distress Syndrome (CARDS) toxin as being …
An Analysis Of Crispr-Cas Gene Editing In Agriculture, Ashley Laliberte
An Analysis Of Crispr-Cas Gene Editing In Agriculture, Ashley Laliberte
Honors Scholar Theses
The CRISPR-Cas system is a promising form of gene editing, especially for the agriculture industry. The ability to make single-nucleotide edits within a gene of interest, without the need to introduce foreign DNA, is a powerful tool for designing healthier and more efficient crops and food animals. This system provides opportunity for increased nutritional value, decreased food waste, and more economically and environmentally sustainable food production. Though this biotechnology is facing mechanistic limitations due to off-target effects and inefficient homology-directed repair, vast improvements have already been made to improve its efficacy. The CRISPR-Cas system is already the most advanced form …
