A Conserved Mechanism For Hormesis In Molecular Systems, Sharon N. Greenwood, Regina G. Belz, Brian P. Weiser
A Conserved Mechanism For Hormesis In Molecular Systems, Sharon N. Greenwood, Regina G. Belz, Brian P. Weiser
Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship
Hormesis refers to dose-response phenomena where low dose treatments elicit a response that is opposite the response observed at higher doses. Hormetic dose-response relationships have been observed throughout all of biology, but the underlying determinants of many reported hormetic dose-responses have not been identified. In this report, we describe a conserved mechanism for hormesis on the molecular level where low dose treatments enhance a response that becomes reduced at higher doses. The hormetic mechanism relies on the ability of protein homo-multimers to simultaneously interact with a substrate and a competitor on different subunits at low doses of competitor. In this …
The Use Of Nebulizer Medications As A Possible Treatment For Covid-19, Jacob Kaufman
The Use Of Nebulizer Medications As A Possible Treatment For Covid-19, Jacob Kaufman
Honors College Theses
For the past few years, the COVID-19 pandemic has been the focal point in healthcare and research. This disease has permanently changed daily life and left a historic impact on the world. Most people have felt the effects of this pandemic either directly, via infection, or indirectly, via change in workflow, financial impact, etc. The main question for this virus still remains today; how do we treat this illness effectively? While many ideas are being tested and suggested, a definite answer has yet to be procured. Vaccine rates are climbing on a daily basis, serving as the first and most …
Investigating The Efficacy Of Tazemetosttat For In Vitro Treatment Of Human Triple Negative Breast Cancer Cells, Harshita Indukuri
Investigating The Efficacy Of Tazemetosttat For In Vitro Treatment Of Human Triple Negative Breast Cancer Cells, Harshita Indukuri
Honors Scholars Collaborative Projects
Cancer is a formidable, genetic disease that affects many people, either directly or indirectly. Breast cancer is the most commonly diagnosed cancer worldwide (31). Triple-negative breast cancer (TNBC) is a type of breast cancer that has a higher lethality compared to other breast cancers and has a poor prognosis due to its highly invasive nature and limited treatment options. Finding safe, effective, and accessible treatment for TNBC is integral to treating TNBC patients. Tazemetostat is an EZH2-inhibitor that has recently been approved for use in epithelioid sarcoma (23). EZH2 is an overexpressed protein in many cancers, including TNBC (11). However, …
The Development Of Inhibitors For Sars-Cov-2 Orf8, My Thanh Thao Nguyen
The Development Of Inhibitors For Sars-Cov-2 Orf8, My Thanh Thao Nguyen
CSB and SJU Distinguished Thesis
An unexpected outbreak of SARS-CoV-2 caused a worldwide pandemic in 2020. Many repurposed drugs were tested, but there are currently only three FDA approved antivirals (Merck’s antiviral Molnupiravir, Pfizer’s antiviral Paxlovid, and Remdisivir).1 Most of the antiviral drugs tested SARS-CoV-2 main protease and RNA-dependent RNA polymerase. However, it is important to explore different drug targets of SARS-CoV-2 to prepare for the virus mutations of the future. This research looks at an alternative approach in which SARSCoV- 2 Open Reading Frame 8 (ORF8), which has been shown to be a rapidly evolving hypervariable gene, was chosen to be the protein of …
Investigation Of Oncogenic Ras And Endoplasmic Reticulum-Mitochondria Calcium Flux And Their Relationship In The Context Of Tumorigenesis, Emma Anderson
Senior Honors Theses
Intracellular calcium as a signaling molecule is a pervasive feature of cellular pathways, especially those that manage internal homeostasis and transitions through the cell cycle, so much so that regulated, responsive calcium flux between the endoplasmic reticulum (ER) and the mitochondria has been suggested to play a major role in cancer development. Another factor commonly implicated in tumorigenesis is RAS, an oncogene that controls signaling for many pathways that are also regulated by calcium. While both calcium and oncogenic RAS signaling are implicated in cancer development, possible links between them have yet to be determined. The identification of these links …
Efforts To Increase The Ketamine-Like Activity Of The Rapid-Acting Antidepressant Ro-25-6981 (Mi-4) By Increasing Ampa Potentiation, Nathan Heger
Annual Research Symposium
The small molecule ketamine has generated much interest due to its rapid antidepressant effects. Despite having a rapid onset, ketamine has poor bioavailability, short duration of action, toxicities with long-term use, and a high potential for abuse. The molecule MI-4 (RO 25-6981) has also been shown to have both a rapid and sustained antidepressant effect. Most of the research into the mechanism of the rapid onset of MI-4 and ketamine has focused on their interaction with the NMDA receptor in addition to some monoamine transporters. Some recent publications have shown a significant role of AMPA receptors in the ketamine antidepressant …
