Yap Induces A Prorenewal Metabolic State In Cardiomyocytes, Lin Liu, Jeffrey D Steimle, Chang-Ru Tsai, Fansen Meng, Yuka Morikawa, Yi Zhao, Sandra Carmichael, Xiao Li, James F Martin

Faculty, Staff and Students Publications

BACKGROUND: Cardiomyocytes, as highly specialized and differentiated somatic cells, possess a limited capacity for renewal. Neonatal rodents possess the ability to regenerate cardiomyocytes after injury; however, this regenerative capacity declines rapidly with cardiomyocyte maturation, suggesting an inhibitory network between cellular maturation and cardiomyocyte proliferation. Maturing cardiomyocytes undergo a metabolic shift from predominantly glycolysis in the neonatal state to increased fatty acid oxidation in the mature state, which poses a barrier to cardiomyocyte proliferation and cardiac regenerative repair. YAP, a transcriptional cofactor regulated by the Hippo signaling pathway, promotes cardiac regenerative repair. We investigated the role of YAP in mediating metabolic …

Molecular Mechanism Of Wdfy4-Mediated Cross-Presentation By Type 1 Conventional Dendritic Cells, Ray Andrew Ohara

Arts & Sciences Graduate Student Theses and Dissertations

Type 1 conventional dendritic cells (cDC1s) are a subset of antigen-presenting cells required for the activation of T cells during anti-viral and anti-tumoral immune responses. cDC1s specialize in cross-presentation (XP), or the MHC-I presentation of exogenous antigens, which allows them to prime antigen-specific CD8+ T cells. In classical MHC-I presentation, cytosolic antigens are processed through the endoplasmic reticulum (ER), relying on both proteasomes and transport associated with antigen processing (TAP). In contrast, the molecular mechanism of XP remains less understood, especially in regard to how the antigens are processed, how the peptides are loaded, and why this function is specialized …

Michigan Tech Publications

Effective fishery management policy depends on accurate life-history data, particularly for harvested species. Longevity is a core life-history trait that is directly related to annual survival and lifetime reproductive potential, but fish longevity is generally not well documented, particularly for long-lived species. We used capture-mark-recapture data spanning 44 years as an alternative method to estimate sex-specific adult lake sturgeon (Acipenser fulvescens) average annual growth and longevity for five populations in the Laurentian Great Lakes. We determined individual fish average annual growth and fit population and sex-specific exponential lines for average annual growth as a function of fish length at initial …

Nature-Based Solutions, green-finance instruments and policies are now routinely constructed around carbon sequestration/storage (CSS) and nutrient bioremediation (NB). This integration builds on how Market-Based Instruments (e.g. payments-for-ecosystem-services) are regularly used in policies focused on terrestrial ecosystems. In marine and coastal systems poor understanding of CSS/NB biophysical processes and impacts of ecosystem quality/stressors, combined with methods and governance framework knowledge gaps, generate substantial uncertainty in outcomes. Reductions in output confidence preclude integration into Nature-Based Solutions, stifling market-based investment centred on conserving and restoring temperate coastal ecosystems. To navigate this complex, rapidly evolving area, researchers from six continents engaged in a Priority …
