Pannexin3 In Exercise, Obesity, And Osteoarthritis, Brent Wakefield

Electronic Thesis and Dissertation Repository

Pannexin 3 (PANX3), is a glycoprotein that oligomerizes to form mechano-sensitive channels expressed in musculoskeletal tissues, and has been identified as a potential target for the treatment of obesity and osteoarthritis (OA). Obesity and OA are two of the most prevalent diseases worldwide, leading to disability and even death. These conditions are thought to originate from a complex interaction between genetics, aging, sex, and modifiable lifestyle factors, such as exercise. Investigating the interactions between genetic and exercise may provide a more comprehensive, context-specific understanding of gene function. This thesis aimed to understand the interactions between PANX3 and exercise interventions on …

The Effect Of Running On The Onset And Development Of Osteoarthritis, Jordan Hekman

Senior Honors Theses

Osteoarthritis is a prominent and debilitating form of joint disease characterized by pain and deterioration of the articular cartilage and other tissues in the affected joint. Research has identified a variety of risk factors for osteoarthritis, including age, obesity, gender, previous injury, and occupation. The relationship between running and osteoarthritis is a topic of particular interest because of the prevalence of running as a simple and physiologically beneficial form of exercise. Increasing evidence suggests that recreational running has at worst no effect and at best a protective effect on joint and articular cartilage health in contrast to high-intensity professional/elite-level running …

BACKGROUND: Computational fluid dynamics has shown good agreement with contrast-enhanced magnetic resonance imaging measurements in cardiovascular disease applications. We have developed a biomechanical model of microvascular perfusion using contrast-enhanced magnetic resonance imaging signal intensities derived from skeletal calf muscles to study peripheral artery disease (PAD). METHODS AND RESULTS: The computational microvascular model was used to study skeletal calf muscle perfusion in 56 in-dividuals (36 patients with PAD, 20 matched controls). The recruited participants underwent contrast-enhanced magnetic resonance imaging and ankle-brachial index testing at rest and after 6-minute treadmill walking. We have determined associations of microvascular model parameters including the transfer …

Background: Intramuscular fat (IMF) and intramuscular connective tissue (IMC) are often seen in human myopathies and are central to beef quality. The mechanisms regulating their accumulation remain poorly understood. Here, we explored the possibility of using beef cattle as a novel model for mechanistic studies of intramuscular adipogenesis and fibrogenesis.

Methods: Skeletal muscle single-cell RNAseq was performed on three cattle breeds, including Wagyu (high IMF), Brahman (abundant IMC but scarce IMF), and Wagyu/Brahman cross. Sophisticated bioinformatics analyses, including clustering analysis, gene set enrichment analyses, gene regulatory network construction, RNA velocity, pseudotime analysis, and cell-cell communication analysis, were performed to elucidate …
