Department of Biochemistry: Faculty Publications

Obesity is a leading risk factor for type-2 diabetes. Diabetes often leads to the dysregulation of angiogenesis, although the mechanism is not fully understood. Previously, long noncoding RNAs (lncRNAs) have been found to modulate angiogenesis. In this study, we asked how the expression levels of lncRNAs change in endothelial cells in response to excessive palmitic acid treatment, an obesitylike condition. Bioinformatics analysis revealed that 305 protein-coding transcripts were upregulated and 70 were downregulated, while 64 lncRNAs were upregulated and 46 were downregulated. Gene ontology and pathway analysis identified endoplasmic reticulum stress, HIF-1 signaling, and Toll-like receptor signaling as enriched after …

Molecular Differentiation Of Astragalus Species And Varieties From The Western United States: The Chloroplast Dna Bridge Between Evolution And Molecular Systematics, Marwa Neyaz, Daniel Cook, Rebecca Creamer

Poisonous Plant Research (PPR)

Locoweeds are the most widespread poisonous plant problem in the world and have been reported in the Western United States since the 1800s, causing tremendous losses in livestock. Consumption of locoweeds by grazing animals stimulates the neurological disease, locoism, characterized by weight loss, ataxia, and lack of muscular coordination. The name locoweed is used for Astragalus and Oxytropis species known to contain swainsonine, the toxic principle produced by the plant endophytic fungus Undifilum. Astragalus includes 2,500-3,000 species and many varieties that have almost identical morphological characteristics that overlap among species, leading to improper identification. Therefore, the aim of this study …

Amino Acid Quantification For Dmc Biotechnologies, Russell Beckerman, Rebecca Hines, Kenya Jacob, Megan Mccabe, Ju Yun Lee

ENGS 89/90 Reports

From pharmaceuticals to biofuels, fermentation bioprocessing has gained traction in many industries reaching a global market value of almost $60 billion in 2018. However, applications of bioprocessing have been limited in scope due to high capital costs, long development times, and difficulties maintaining productivity during scale-up. Furthering development and scale-up of fermentation bioprocesses require careful monitoring and control through analytical chemistry. Currently, there are no small molecule quantification techniques that are sufficiently accurate, inexpensive, and high-throughput. This investigation explores viability of a novel quantification assay for amino acids in fermentation broth leveraging molecularly imprinted polymers (MIPs) and gold nanoparticles (AuNPs).

A Positive Feedback Loop Of Hippo- And C-Jun-Amino-Terminal Kinase Signaling Pathways Regulates Amyloid-Beta-Mediated Neurodegeneration, Madison Irwin, Meghana Tare, Aditi Singh, Oorvashi Roy Puli, Neha Gogia, Matthew Riccetti, Prajakta Deshpande, Madhuri Kango-Singh, Amit Singh

Biology Faculty Publications

Alzheimer's disease (AD, OMIM: 104300) is an age-related disorder that affects millions of people. One of the underlying causes of AD is generation of hydrophobic amyloid-beta 42 (Aβ42) peptides that accumulate to form amyloid plaques. These plaques induce oxidative stress and aberrant signaling, which result in the death of neurons and other pathologies linked to neurodegeneration. We have developed a Drosophila eye model of AD by targeted misexpression of human Aβ42 in the differentiating retinal neurons, where an accumulation of Aβ42 triggers a characteristic neurodegenerative phenotype. In a forward deficiency screen to look for genetic modifiers, we identified a molecularly …

Hur Ubiquitination By Brca1/Bard1 And Its Role In Controlling Gene Expression During Dna Damage Response, Gamage M. Aruggoda

Dissertations, Theses, and Capstone Projects

Despite our understanding of the biochemistry of the BRCA1/BARD1 E3 ligase, we know very little of the mechanism by which its cellular substrates, how they are chosen, how its E3 Ub ligase activity is regulated, which are the cofactors involved in this regulation, and how the substrates are modified during DDR. In this dissertation, I further evaluate BRCA1/BARD1-mediated E3 ligase activity and how CstF-50 and p97 regulate this reaction working as cofactors. My data show that BRCA1/BARD1 is an E3 ligase that ubiquitinates the RNA binding protein Human antigen R(HuR).

HuR is abundant in the nucleus and is transported to …

Constitutionalizing Nature's Law: Dignity And The Regulation Of Biotechnology In Switzerland, James Toomey

Elisabeth Haub School of Law Faculty Publications

The Swiss Constitution was amended by referendum in 1992 to include two unique provisions: Article 119, which imposes strict limits on genetic and reproductive technologies in humans in order to protect ‘human dignity’, and Article 120, which commits the Swiss federal government to limiting genetic technologies in non-human species on the basis of the ‘dignity of the creature’. This article analyzes the role of ‘dignity’ as a limit on biotechnologies in the Swiss constitutional order. It concludes that the understanding of dignity the constitution embraces codifies a contestable metaphysical theory of value at the constitutional level. Specifically, the Swiss constitutional …

Sestrin2 Phosphorylation By Ulk1 Induces Autophagic Degradation Of Mitochondria Damaged By Copper-Induced Oxidative Stress, Heejeong Kim, Byeong Tak Jeon, Isaac M. Kim, Sydney Townsend, Carolyn M. Lorch, Martonio Viana, Jacob F. Myers, Caroline J. Trupp, Zachary T. Whipps, Mondira Kundu, Soonkyu Chung, Xinghui Sun, Oleh Khalimonchuk, Jaekwon Lee, Seung-Hyun Ro

Department of Biochemistry: Faculty Publications

Selective autolysosomal degradation of damaged mitochondria, also called mitophagy, is an indispensable process for maintaining integrity and homeostasis of mitochondria. One well-established mechanism mediating selective removal of mitochondria under relatively mild mitochondria-depolarizing stress is PINK1-Parkin-mediated or ubiquitin-dependent mitophagy. However, additional mechanisms such as LC3-mediated or ubiquitin-independent mitophagy induction by heavy environmental stress exist and remain poorly understood. The present study unravels a novel role of stress-inducible protein Sestrin2 in degradation of mitochondria damaged by transition metal stress. By utilizing proteomic methods and studies in cell culture and rodent models, we identify autophagy kinase ULK1-mediated phosphorylation sites of Sestrin2 and demonstrate …

Numerical Modeling Of Submicron Particles For Acoustic Concentration In Gaseous Flow, Jizhou Liu, Xiaodong Li, Fang Q. Hu

Mathematics & Statistics Faculty Publications

This paper intends to explore the rationality and feasibility of modeling dispersed submicron particles in air by a kinetic-based method called the unified gas-kinetic scheme (UGKS) and apply it to the simulation of particle concentration under a transverse standing wave. A gas-particle coupling scheme is proposed where the gas phase is modeled by the two-dimensional linearized Euler equations (LEE) and, through the analogous behavior between the rarefied gas molecules and the air-suspended particles, a modified UGKS is adopted to estimate the particle dynamics. The Stokes' drag force and the acoustic radiation force applied on particles are accounted for by introducing …

Combination Of Investigational Cell-Based Therapy And Deep Brain Stimulation To Alter The Progression Of Parkinson’S Disease, Nader El Seblani

Identification Of Novel Antimalarials From Natural Product Inspired Libraries, David Perry

Electronic Theses and Dissertations, 2020-2023

To identify novel antimalarials from unexplored areas of chemical space, we have utilized two approaches: (a) using Torrey Pines Institute for Molecular Studies (TPIMS) proprietary high-density combinatorial libraries containing a large number of small molecule compounds residing largely in the underexplored areas of chemical space; and, (b) using novel, complexity-to-diversity/ring distortion of available natural products. The first approach involved the screening of more than 30 million compounds derived from 81 small molecule libraries, built on 81 distinct scaffolds. From this, we identified the pyrrolidine bis-cyclic guanidine library (TPI-1955) to be one of the most active and selective for antiplasmodial activity. …
