Mild traumatic brain injury (mTBI) accounts for 70-90% of all TBI cases. Lipid metabolites have important roles in plasma membrane biogenesis, function, and cell signaling. As TBI can compromise plasma membrane integrity and alter brain cell function, we sought to identify circulating phospholipid alterations after mTBI, and determine if these changes were associated with clinical outcomes. Patients with mTBI (Glasgow Coma Score [GCS] ≥13 and loss of consciousness <30 >min) were recruited. A total of 84 mTBI subjects were enrolled after admission to a level I trauma center, with the majority having evidence of traumatic intracranial hemorrhage on brain computed tomography …

Cow's milk is frequently included in the human diet, but the relationship between milk intake and type 2 diabetes (T2D) remains controversial. Here, using data from the Hispanic Community Health Study/Study of Latinos, we show that in both sexes, higher milk intake is associated with lower risk of T2D in lactase non-persistent (LNP) individuals (determined by a variant of the lactase LCT gene, single nucleotide polymorphism rs4988235 ) but not in lactase persistent individuals. We validate this finding in the UK Biobank. Further analyses reveal that among LNP individuals, higher milk intake is associated with alterations in gut microbiota (for …

The Relationship Of Neighborhood Disadvantage, Biological Aging, And Psychosocial Risk And Resilience Factors In Heart Failure Incidence Among Black Persons: A Moderated Mediation Analysis, Ganga S Bey, James R Pike, Anthony S Zannas, Qian Xiao, Bing Yu, Amil M Shah, Priya Palta

Faculty, Staff and Student Publications

Objectives: Deprived living environments contribute to greater heart failure (HF) risk among non-Hispanic Black persons, who disproportionately occupy disadvantaged neighborhoods. The mechanisms for these effects are not fully explicated, partially attributable to an insufficient understanding of the individual factors that contribute additional risk or resilience to the impact of neighborhood disadvantage on health. The objective of this study was, therefore, to clarify the complex pathways over which such exposures act to facilitate more targeted, effective interventions. Given the evidence for a mediating role of biological age and a moderating role of individual psychosocial characteristics in the neighborhood disadvantage-HF link, we …

Using Focus Groups To Explore Older Black Men's Perception Of Dietary Interventions., Ashley R Shaw, Eric D Vidoni, Mickeal N Key, Brandon A Yates, Roland Thorpe

Faculty, Staff and Student Publications

Older Black men are underrepresented in research despite being disproportionately affected by Alzheimer’s disease (AD) and cardiovascular (CV) risk factors related to AD compared with non-Hispanic Whites. Although dietary interventions have shown promise to reduce modifiable CV risk factors related to AD, Black Americans have lower adherence likely due to lack of cultural considerations. Using a noninterventional convergent parallel mixed-methods approach, this study examined the cultural contexts that inform perceptions of dietary interventions among older Midwestern Black men. All participants completed an online demographic and dietary habit survey prior to focus group discussions. Two focus group discussion sessions were conducted …

Proteoglycans In Mechanobiology Of Tissues And Organs: Normal Functions And Mechanopathology, Mary C Farach-Carson, Danielle Wu, Cristiane Miranda França

Faculty, Staff and Student Publications

Proteoglycans (PGs) are a diverse class of glycoconjugates that serve critical functions in normal mechanobiology and mechanopathology. Both the protein cores and attached glycosaminoglycan (GAG) chains function in mechanically-sensitive processes, and loss of either can contribute to development of pathological conditions. PGs function as key components of the extracellular matrix (ECM) where they can serve as mechanosensors in mechanosensitive tissues including bone, cartilage, tendon, blood vessels and soft organs. The mechanical properties of these tissues depend on the presence and function of PGs, which play important roles in tissue elasticity, osmolarity and pressure sensing, and response to physical activity. Tissue …

Placental Co-Transcriptional Activator Vestigial-Like 1 (Vgll1) Drives Tumorigenesis Via Increasing Transcription Of Proliferation And Invasion Genes, Heather M Sonnemann, Barbara Pazdrak, Barbara Nassif, Yimo Sun, Lama Elzohary, Amjad H Talukder, Arjun S Katailiha, Krishna Bhat, Gregory Lizée

Faculty, Staff and Student Publications

Introduction: Vestigial-like 1 (VGLL1) is a co-transcriptional activator that binds to TEA domain-containing transcription factors (TEADs). Its expression is upregulated in a variety of aggressive cancer types, including pancreatic and basal-like breast cancer, and increased transcription of VGLL1 is strongly correlated with poor prognosis and decreased overall patient survival. In normal tissues, VGLL1 is most highly expressed within placental trophoblast cells, which share the common attributes of rapid cellular proliferation and invasion with tumor cells. The impact of VGLL1 in cancer has not been fully elucidated and no VGLL1-targeted therapy currently exists.

Methods: The aim of this study was to …

Perspective: The Evolution Of Hormones And Person Perception-A Quantitative Genetic Framework, Christopher I Gurguis, Tyler S Kimm, Teresa A Pigott

Faculty, Staff and Student Publications

Evolutionary biology provides a unifying theory for testing hypotheses about the relationship between hormones and person perception. Person perception usually receives attention from the perspective of sexual selection. However, because person perception is one trait in a suite regulated by hormones, univariate approaches are insufficient. In this Perspectives article, quantitative genetics is presented as an important but underutilized framework for testing evolutionary hypotheses within this literature. We note tacit assumptions within the current literature on psychiatric genetics, which imperil the interpretation of findings thus far. As regulators of a diverse manifold of traits, hormones mediate tradeoffs among an array of …

Depression has strong negative impacts on how individuals function, leading to the assumption that there is strong negative selection on this trait that should deplete genetic variation and decrease its prevalence in human populations. Yet, depressive symptoms remain common. While there has been a large body of work trying to resolve this paradox by mapping genetic variation of this complex trait, there have been few direct empirical tests of the core assumption that there is consistent negative selection on depression in human populations. Here, we use a unique long-term dataset from the National Health and Nutrition Examination Survey that spans …

FGF5 functions as a negative regulator of the hair cycle in mammals. It is expressed in the outer root sheath of hair follicles during the late anagen phase of the hair cycle. It functions as a signaling molecule, mediating the transition of the anagen growth phase to catagen regression phase of the hair cycle. Spontaneous and engineered FGF5 mutations in mammalian animal models result in long hair phenotypes. In humans, inherited FGF5 mutations result in trichomegaly (long eyelashes). Knockdown of fgf5 in zebrafish embryos results in inner ear alterations. Alterations in FGF5 expression are also associated with various human pathologies.
