Environmental Regulation Of The Heart: The Role Of Non-Coding Rna And Epigenetics In Influencing Mitochondrial And Cellular Health, Quincy Alexander Hathaway
Environmental Regulation Of The Heart: The Role Of Non-Coding Rna And Epigenetics In Influencing Mitochondrial And Cellular Health, Quincy Alexander Hathaway

The mitochondrion, a small but ubiquitously distributed organelle in the cell, continues to be the focus of many disease pathogeneses, tissue and organ dysfunctions, and other morbidities that occur throughout the body. The purpose of this work was to understand how cardiac mitochondrion are altered in disease and pathological states, specifically in their adaptation to environmentally stimulated regulatory networks, such as epigenetic modifications and promotion/inhibition of non-coding RNAs. Acute stress to mitochondrial regulation (inhalation toxicology) as well as chronic (type 2 diabetes mellitus) was examined. Using a FVB transgenic microRNA-378a mouse knockout model, the cardiovascular impact derived from altering the …

DNA damage is presumed to be one type of stochastic macromolecular damage that contributes to aging, yet little is known about the precise mechanism by which DNA damage drives aging. Here, we attempt to address this gap in knowledge using DNA repair-deficient C. elegans and mice. ERCC1-XPF is a nuclear endonuclease required for genomic stability and loss of ERCC1 in humans and mice accelerates the incidence of age-related pathologies. Like mice, ercc-1 worms are UV sensitive, shorter lived, display premature functional decline and they accumulate spontaneous oxidative DNA lesions (cyclopurines) more rapidly than wild-type worms. We found that ercc-1 worms …

Quantum confined materials have been extensively studied for photoluminescent applica- tions. Due to intrinsic limitations of low biocompatibility and challenging modulation, the utilization of conventional inorganic quantum confined photoluminescent materials in bio- imaging and bio-machine interface faces critical restrictions. Here, we present aromatic cyclo-dipeptides that dimerize into quantum dots, which serve as building blocks to further self-assemble into quantum confined supramolecular structures with diverse morphologies and photoluminescence properties. Especially, the emission can be tuned from the visible region to the near-infrared region (420 nm to 820 nm) by modulating the self-assembly process. Moreover, no obvious cytotoxic effect is observed for …

Alzheimer’s disease (AD) is a chronic progressive neurodegenerative disease. Its mechanism is still not clear. Majority of research focused on the central nervous system (CNS) changes, while few studies emphasize on peripheral immune system modulation. Our study aimed to investigate the regulation of the peripheral immune system and its relationship to the severity of the disease after treatment in an AD model of APPswe/PSEN1dE9 transgenic (APP/PS1 Tg) mice. APP/PS1 Tg mice (8 months old) were treated with the ROCK-II inhibitor 1-(5-isoquinolinesulfonyl)- homo-piperazine (Fasudil) (intraperitoneal (i.p.) injections, 25 mg/kg/day), bone marrow stromal cells (BMSCs; caudal vein injections, 1 × 106 BMSCs …

Arl2bp, A Novel Ciliopathy Protein, Is Required For Cilia Microtubule Formation, Abigail Ruth Moye
Graduate Theses, Dissertations, and Problem Reports
Cilia are specialized organelles essential for cellular function. Not surprisingly, mutations in cilia- related genes are linked to multi-syndromic diseases termed ciliopathies. These include blinding diseases such as retinitis pigmentosa (RP). One such novel gene is ARL2BP (ARL2-binding protein) and is linked to RP and situs inversus (organ reversal) in humans, a phenotype produced by defects in the nodal cilia of developing embryos. Defects in photoreceptor cilia, as well as situs inversus in human patients, suggest that ARL2BP plays an invaluable role in the structure and function of cilia. However little is known about the role for this protein in …
