The Role Of Sox9 In Epicardial-Mediated Cardiovascular Development And Valve Homeostasis, Andrew Brantley Harvey

MUSC Theses and Dissertations

Congenital heart defects (CHDs) are the most common birth defects in humans, affecting as many as 1% of live births, thereby representing a major public health burden. These defects arise when signaling pathways and mechanical forces guiding heart development are disrupted, either by genetic mutations, aneuploidies, environmental influences, or any combination of these factors. The vast majority of CHDs have undetermined etiologies. Understanding the molecular and cellular mechanisms of normal heart development is critical for unraveling the origins of CHDs and for developing more effective diagnostics and interventional treatments for those affected by cardiovascular diseases of developmental origin.

Investigation Of Trimethylenemethane Cyclopentyl-Annulations As A Strategy To Obtain A Functionalized Angular Triquinane Skeleton †, S. M. Webber, Wade A. Russu

Pacific Faculty Work

The angular triquinane carbocyclic ring system is a component of many natural products found in numerous terrestrial and marine plants. A strategy for the synthesis of functionalized angular triquinanes utilizing two trimethylenemethane (TMM)-based [3+2] cycloaddition reactions is presented. This synthetic strategy employs the intermolecular dyil-trapping reaction to give eventual access to the bicyclo[3.3.0]oct-1-en-3-one system. A subsequent [3+2] cycloaddition with a TMM equivalent provides the angular triquinane carbocyclic framework.

BACKGROUND: Endocrine therapy (ET) has improved the clinical outcomes of Estrogen receptor alpha-positive (ERɑ +) breast cancer (BC) patients, even though resistance to ET remains a clinical issue. Mutations in the hormone-binding domain of ERɑ represent an acquired intrinsic mechanism of ET resistance. However, the latter also depends on the multiple functional interactions between BC cells and the tumor microenvironment (TME). Here, we investigated how the most common Y537S-ERɑ mutation may influence the behavior of fibroblasts, the most prominent component of the TME.

METHODS: We conducted coculture experiments with normal human foreskin fibroblasts BJ1-hTERT (NFs), cancer-associated fibroblasts (CAFs), isolated from …

The Relationship Between Spectral Signals And Retinal Sensitivity In Dendrobatid Frogs, Whitney G. Walkowski, Corinne L. Richards-Zawacki, William C. Gordon, Nicolas G. Bazan, Hamilton E. Farris

School of Graduate Studies Faculty Publications

Research on visually driven behavior in anurans has often focused on Dendrobatoidea, a clade with extensive variation in skin reflectance, which is perceived to range from cryptic to conspicuous coloration. Because these skin patterns are important in intraspecific and interspecific communication, we hypothesized that the visual spectral sensitivity of dendrobatids should vary with conspecific skin spectrum. We predicted that the physiological response of frog retinas would be tuned to portions of the visible light spectrum that match their body reflectance. Using wavelength-specific electroretinograms (ERGs; from 350-650 nm), spectrometer measurements, and color-calibrated photography of the skin, we compared retinal sensitivity and …

Oncolytic Virotherapies And Adjuvant Gut Microbiome Therapeutics To Enhance Efficacy Against Malignant Gliomas, Natalie M Meléndez-Vázquez, Candelaria Gomez-Manzano, Filipa Godoy-Vitorino

Faculty, Staff and Student Publications

Glioblastoma (GBM) is the most prevalent malignant brain tumor. Current standard-of-care treatments offer limited benefits for patient survival. Virotherapy is emerging as a novel strategy to use oncolytic viruses (OVs) for the treatment of GBM. These engineered and non-engineered viruses infect and lyse cancer cells, causing tumor destruction without harming healthy cells. Recent advances in genetic modifications to OVs have helped improve their targeting capabilities and introduce therapeutic genes, broadening the therapeutic window and minimizing potential side effects. The efficacy of oncolytic virotherapy can be enhanced by combining it with other treatments such as immunotherapy, chemotherapy, or radiation. Recent studies …

Sleep Architecture Changes In Diabetes., Yuanjie Mao

Ambulatory and Primary Care Articles

Data on the relationship between sleep architecture and diabetes are limited. However, some evidence suggests that slow-wave sleep (SWS) plays a crucial role in maintaining normal glucose homeostasis and influences insulin secretion capacity. Diabetes is often associated with reduced SWS, even in the absence of sleep-disordered breathing. Notably, selective suppression of SWS-without reducing total sleep time-can lead to significant increases in insulin resistance, decreased glucose tolerance, and a higher risk of diabetes. Given the growing interest in non-pharmacological lifestyle interventions, such as modifying sleep architecture, it is important to understand how sleep patterns differ in individuals with diabetes and whether …
