The Microrna Mir-30a Blocks Adipose Tissue Fibrosis Accumulation In Obesity, Pradip K Saha, Robert Sharp, Aaron R Cox, Rabie Habib, Michael J Bolt, Jessica B Felix, Claudia E Ramirez Bustamante, Xin Li, Sung Yun Jung, Kang Ho Kim, Kai Sun, Huaizhu Wu, Samuel Klein, Sean M Hartig

Faculty, Staff and Student Publications

White adipose tissue (WAT) fibrosis occurring in obesity contributes to the inflammatory and metabolic comorbidities of insulin resistance and type 2 diabetes, yet the mechanisms involved remain poorly understood. Here, we report a role for the broadly conserved miRNA miR-30a as a regulator of WAT fibrosis and systemic glucose metabolism. Mice modified to express miR-30a at elevated levels in adipose tissues maintain insulin sensitivity coupled with reduced fatty liver disease when fed a high-fat diet. These effects were attributable to cell-autonomous functions of miR-30a that potently increase expression of adipocyte-specific genes. Proteomic screening revealed miR-30a limits profibrotic programs in subcutaneous …

Predominant-Dominant Chains In Japanese Video Game Music, Evan R. Davis

Master's Theses

The short looping forms in Japanese video game music feature rapid modulations based on common chord progressions that necessitate contextual readings of harmonies in various keys to isolate how they manipulate tonal space. One such progression used by Japanese game music composers utilizes chains of predominant-dominant chords to move key centers by conflating function in minor-third related keys. These triumphant sounding transitional phrases are uniquely valuable in a medium dominated by stories of heroism and fighting authorities both earthly and divine. Building on the functional framework of 19^th century theorists and existing popular music research, two models are created …

Female Preference And Prezygotic Isolation In The Fundulus Notatus Species Complex, Emilee K. Holderness

Master's Theses

Understanding how reproductive isolation arises between closely related species is central to evolutionary research. Hybridization is widespread across taxa and shaped by interactions among environmental factors, evolutionary history, genetic compatibility, and behavior. These forces often operate nonlinearly across space and time, yet mate choice is frequently assessed under artificial conditions that may not reflect natural behavior. To address this limitation, female mate preference was investigated within the Fundulus notatus species complex, where F. notatus and F. olivaceus hybridize at varying rates across replicate contact zones. Using a free-choice design, behavioral trials were conducted with individuals from populations characterized by high …

High-Density Lipoprotein-Associated Cholesterol Abnormalities In A Clinical Outcomes Study Of Dysferlin-Deficient Limb-Girdle Muscular Dystrophy Type R2, Zoe White, Alan Pestronk, Et Al.

2020-Current year OA Pubs

BACKGROUND: Limb-girdle muscular dystrophy (MD) type R2 (LGMDR2, formerly LGMD2B) is an autosomal recessive form of MD caused by variants in the dysferlin gene, DYSF. It leads to slow proximal and distal muscle weakening that generally results in loss of ambulation around early adulthood but without the lethal cardiorespiratory dysfunction observed in the more severe Duchenne MD. How loss of dysferlin causes muscle fibre death is poorly understood, but recent evidence suggests a link between muscle wasting and loss of muscle cholesterol homeostasis with circulating lipoprotein abnormalities in many forms of MD.

METHODS: Cross-sectional circulating total cholesterol (CHOL), high-density lipoprotein-associated …

Would Order-By-Order Auctions Be Competitive?, Thomas Ernst, Chester Spatt, Jian Sun

Research Collection Lee Kong Chian School Of Business

We model two methods of executing segregated retail orders: brokers’ routing,whereby brokers allocate orders using the market maker’s overall performance, andorder-by-order auctions, where market makers bid on individual orders, a recent U.S.Securities and Exchange Commission proposal. Order-by-order auctions improve al-locative efficiency, but face a winner’s curse reducing retail investor welfare, partic-ularly when liquidity is limited. Additional market participants competing for retailorders fail to improve total efficiency and investor welfare when entrants possess in-formation superior to incumbent wholesalers. Our results hold when new entrants are less informed or the information structure differs. We also examine the cross-subsidization of brokers’ routing.

Human Salivary Gland Stem/Progenitor Cells For Tissue Engineering, Sars-Cov-2 Susceptibility, And Neurointegration, Caitlynn Barrows

Dissertations and Theses (Open Access)

Salivary glands and the saliva they secrete are important for digestion, chewing, and maintaining oral health. Reduced saliva production leads to a decreased quality of life for patients experiencing hyposalivation as a result of disease or injury, thus a large effort has been dedicated to developing materials and medium to recapitulate the structure of the gland for regenerative medicine. In doing so, we have come closer to developing a more complex model to study disease. These models, however, do not yet fully recapitulate the gland. In this dissertation, we describe a new cell source that can be used to develop …

Integrating Bulk And Single-Cell Transcriptomics To Investigate Intratumor Heterogeneity, Shuai Guo

Dissertations and Theses (Open Access)

Cancers are heterogeneous mixtures of tumor and surrounding cells, where each component comprises multiple distinct sub-types and/or states. Understanding the cell-type-specific contributions is critical for advancing cancer biology, yet high-throughput expression profiles from tumor tissues only represent combined signals from all diverse cellular sources. Bulk deconvolution with single-cell/nucleus (sc/sn) RNA-seq data has emerged as a powerful approach to dissect both cellular composition and cell-type-specific expression patterns, yet the technological discrepancy across sequencing platforms limits accuracy.

To systematically evaluate the impact of platform discrepancies on bulk deconvolution, we first generated a benchmark dataset of 24 healthy retinas with paired bulk and …

A Game Of Chicken: Exploring Religiosity, Gambling, And Acts Of Worship In Ren Galeno's Graphic Novel Sa Wala (Nothing To Lose), Elisha Camille Catimpo

Literary and Cultural Studies Program Faculty Publications

There are few more devout than a gambler. By his nature, he believes in something bigger than himself—be it faith, chance, luck, fortune, or some other greater power. The Philippine tradition of cockfighting, or sabong, is known for its established position in Philippine culture and the superstitious nature of the sabungero. In his 1977 book In Defense of Cockfighting, Nid Anima even goes as far as to claim that the Philippines is the cockfight Mecca of the world. In spite of the contradictory implications, there is a deep religiosity at work here, which makes the sabong unique in the Southeast …

The Marginalization Of Black Students And The Burnout Of Black Teachers, Jasmine N. Wilson

Language Arts Journal of Michigan

Black students' language and culture should matter inside the classroom, but the K-12 education system perpetuates racist ideologies that otherwise stifle and shame Black students and their identities. There is a disproportion between the number of White teachers and Black students in minority-serving K-12 institutions, and this racial mismatch severely influences Black students’ academic success. In addition to the racial mismatch between White teachers and Black students, K-12 institutions foster a prejudiced learning environment that condemns African American English speakers. There is an abundance of research that suggests that Black teachers, Black culture, and Black English are of the utmost …

Anisotropic Object-Based Shifts Of Attention Arise From Unequal Influences Of Visual Field Meridians On Neural Attention Gradients, David H. Hughes, Adam J. Barnas, Adam S. Greenberg

Biomedical Engineering Faculty Research and Publications

Object-based attention prioritizes the processing of information appearing within a selected object. We previously showed an object-based shift direction anisotropy (SDA) whereby horizontal shifts are more efficient than vertical shifts (Barnas AJ, Greenberg AS. Atten Percept Psychophys 78: 1985–1997, 2016; Barnas AJ, Greenberg AS. Vis Cogn 27: 768–791, 2019), an effect modulated by the visual field meridians (Barnas AJ, Greenberg AS. Q J Exp Psychol (Hove) 77: 2516–2532, 2024). Our present aim was to understand how the functional brain mechanisms of attention give rise to the SDA. We hypothesized that the SDA arises from attentional resources being partitioned differently by …
