Cold And Salt Stress Responses Are Mediated By Gcn2 Through Reactive Oxygen Species Emanating From The Chloroplast., Philip Wayne Morgan, Ansul Lokdarshi, Albrecht G. Vonarnim Apr 2019

Cold And Salt Stress Responses Are Mediated By Gcn2 Through Reactive Oxygen Species Emanating From The Chloroplast., Philip Wayne Morgan, Ansul Lokdarshi, Albrecht G. Vonarnim

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Cytosolic mRNA translation is subject to global and mRNA-specific control mechanisms in order to balance overall energy and metabolic resources with demand. Phosphorylation of eukaryotic translation initiation factor eIF2a is central to an immediate and reversible switch that represses translation globally. The GCN2 kinase (General Control Non-derepressible-2), is the only known kinase for eIF2a in plants. It can be activated by herbicides that inhibit amino acid biosynthesis. In the study presented here, we provide preliminary evidence of a novel signaling mechanism in Arabidopsis thaliana, where the GCN2-eIF2a paradigm may extend the narrow definition of retrograde signaling by the chloroplast from ...


Promoter Library Designed For Fine-Tuned Gene Expression In Pichia Pastoris, Franz S. Hartner, Claudia Ruth, David Langenegger, Sabrina N. Johnson, Petr Hyka, Geoff P. Lin-Cereghino, Joan Lin-Cereghino, Karin Kovar, James Cregg, Anton Glieder Mar 2019

Promoter Library Designed For Fine-Tuned Gene Expression In Pichia Pastoris, Franz S. Hartner, Claudia Ruth, David Langenegger, Sabrina N. Johnson, Petr Hyka, Geoff P. Lin-Cereghino, Joan Lin-Cereghino, Karin Kovar, James Cregg, Anton Glieder

Joan Lin-Cereghino

Although frequently used as protein production host, there is only a limited set of promoters available to drive the expression of recombinant proteins in Pichia pastoris. Fine-tuning of gene expression is often needed to maximize product yield and quality. However, for efficient knowledge-based engineering, a better understanding of promoter function is indispensable. Consequently, we created a promoter library by deletion and duplication of putative transcription factor-binding sites within the AOX1 promoter (PAOX1) sequence. This first library initially spanned an activity range between ∼6% and >160% of the wild-type promoter activity. After characterization of the promoter library employing a green ...

Endosome To Golgi Retrieval Of The Vacuolar Protein Sorting Receptor, Vps10p, Requires The Function Of The Vps29, Vps30, And Vps35 Gene Products, Matthew N. J. Seaman, Eric G. Marcusson, Joan Lin-Cereghino, Scott D. Emr Mar 2019

Endosome To Golgi Retrieval Of The Vacuolar Protein Sorting Receptor, Vps10p, Requires The Function Of The Vps29, Vps30, And Vps35 Gene Products, Matthew N. J. Seaman, Eric G. Marcusson, Joan Lin-Cereghino, Scott D. Emr

Joan Lin-Cereghino

Mutations in the S. cerevisiae VPS29 and VPS30 genes lead to a selective protein sorting defect in which the vacuolar protein carboxypeptidase Y (CPY) is missorted and secreted from the cell, while other soluble vacuolar hydrolases like proteinase A (PrA) are delivered to the vacuole. This phenotype is similar to that seen in cells with mutations in the previously characterized VPS10 and VPS35 genes. Vps10p is a late Golgi transmembrane protein that acts as the sorting receptor for soluble vacuolar hydrolases like CPY and PrA, while Vps35p is a peripheral membrane protein which cofractionates with membranes enriched in Vps10p. The ...


The Cytoplasmic Tail Domain Of The Vacuolar Protein Sorting Receptor Vps10p And A Subset Of Vps Gene Products Regulate Receptor Stability, Function, And Localization, Joan Lin-Cereghino, Eric G. Marcusson, Scott D. Emr Mar 2019

The Cytoplasmic Tail Domain Of The Vacuolar Protein Sorting Receptor Vps10p And A Subset Of Vps Gene Products Regulate Receptor Stability, Function, And Localization, Joan Lin-Cereghino, Eric G. Marcusson, Scott D. Emr

Joan Lin-Cereghino

VPS10 of Saccharomyces cerevisiae encodes a type I transmembrane receptor protein required for the sorting of the soluble vacuolar hydrolase carboxypeptidase Y (CPY). To characterize the essential structural features and intercompartmental transport itinerary of the CPY receptor, we have constructed mutant forms of Vps10p that alter the carboxyterminal cytoplasmic tail of the protein. In addition, we have analyzed the effect these mutations as well as mutations in several VPS genes have on the function, stability, and localization of Vps10p. Although wild-type Vps10p is very stable over a 3-h chase period, overproduction of Vps10p results in PEP4-dependent degradation of the receptor ...


Of Course, Humans Are Not Unique!, Bernard Wallner Jan 2019

Of Course, Humans Are Not Unique!, Bernard Wallner

Animal Sentience

This commentary focuses on the question of the uniqueness of humans in comparison to other species and on the false assumption that single arguments support logical conclusions. Comparative analysis of genetic data in humans and nonhuman primates regarding the dopaminergic system of the subcortical mesolimbic reward system highlights homologous traits shared and modified by the process of evolution. Such an analytical approach is more relevant than claims of uniqueness.


The Effects Of Inulin And Galactooligosaccharides On The Production Of Reuterin By Lactobacillus Reuteri, Micah Dwight Forshee Dec 2018

The Effects Of Inulin And Galactooligosaccharides On The Production Of Reuterin By Lactobacillus Reuteri, Micah Dwight Forshee

ELAIA

The microbiome is a dynamic community that can positively and negatively influence host health. Lactobacillus reuteri is a probiotic that has received much attention for its ability to inhibit pathogens such as Salmonella typhimurium, Escherichia coli, and Clostridium difficile. It does so by its unique ability to metabolize glycerol into the antimicrobial compound 3-HPA, which is commonly referred to as reuterin. The ability to secrete reuterin is dependent not only on glycerol availability but also the concentration of glucose. In fact, there appears to be a “goldilocks” ratio between glucose and glycerol as either too much or too little glucose ...


Generating High-Order Optical And Spin Harmonics From Ferromagnetic Monolayers, G.P. Zhang, M.S. Si, M. Murakami, Y.H. Bai, Thomas F. George Nov 2018

Generating High-Order Optical And Spin Harmonics From Ferromagnetic Monolayers, G.P. Zhang, M.S. Si, M. Murakami, Y.H. Bai, Thomas F. George

Thomas George

High-order harmonic generation (HHG) in solids has entered a new phase of intensive research, with envisioned band-structure mapping on an ultrashort time scale. This partly benefits from a flurry of new HHG materials discovered, but so far has missed an important group. HHG in magnetic materials should have profound impact on future magnetic storage technology advances. Here we introduce and demonstrate HHG in ferromagnetic monolayers. We find that HHG carries spin information and sensitively depends on the relativistic spin–orbit coupling; and if they are dispersed into the crystal momentum k space, harmonics originating from real transitions can be k-resolved ...

The Role Of Membrane Excitability In Insulin Regulation, Christopher Howard Emfinger Aug 2018

The Role Of Membrane Excitability In Insulin Regulation, Christopher Howard Emfinger

Arts & Sciences Electronic Theses and Dissertations

In mammals, ATP-sensitive K+ (KATP) channels are essential regulators of insulin secretion from pancreatic islet [beta]-cells, illustrated by the finding that gain-of-function mutations in KATP channels (KATP-GOF) cause neonatal diabetes mellitus (NDM). However, variability in symptom severity and effectiveness of treatment is seen in NDM, even for those with the same mutation and in the same family. Short-term treatment of mice expressing KATP-GOF mutations in [beta]-cells (KATP-GOF mice) with the KATP blocker glibenclamide during disease onset results in two outcomes: one subset becomes severely diabetic (non-remitters), whereas the other subset remains below the glucose levels at which significant ...


Microbial Ecology Of South Florida Surface Waters: Examining The Potential For Anthropogenic Influences, Chase P. Donnelly Aug 2018

Microbial Ecology Of South Florida Surface Waters: Examining The Potential For Anthropogenic Influences, Chase P. Donnelly

HCNSO Student Theses and Dissertations

South Florida contains one of the largest subtropical wetlands in the world, and yet not much is known about the microbes that live in these surface waters. These microbes play an important role in chemical cycling and maintaining good water quality for both human and ecosystem health. The hydrology of Florida’s surface waters is tightly regulated with the use of canal and levee systems run by the US Army Corps of Engineers and The South Florida Water Management District. These canals run through the Everglades, agriculture, and urban environments to control water levels in Lake Okeechobee, the Water Conservation ...


Activities And Classroom Demonstrations In Biological Physics: A Resource Document, Philip C. Nelson, William Berner Jul 2018

Activities And Classroom Demonstrations In Biological Physics: A Resource Document, Philip C. Nelson, William Berner

Department of Physics Papers

We give detailed recipes for a number of classroom demonstrations relevant to biological physics instruction. We developed them mainly for use in 2nd-3rd year undergraduate Physics courses. But you can (and we do) use them for primary school, through high school, up to PhD candidates. You adapt the words for each audience, but a phenomenon is a phenomenon.

We also outline a 1-hour introduction to Python for undergraduate scientific computing.

Finally we document some outcomes from courses taught at U Pennsylvania using these resources and others cited here. This material was presented at a workshop at the AAPT meeting in ...

Mapping Molecular Datasets Back To The Brain Regions They Are Extracted From: Remembering The Native Countries Of Hypothalamic Expatriates And Refugees, Arshad M. Khan, Alice H. Grant, Anais Martinez, Gully Apc Burns, Brendan S. Thatcher, Vishwanath T. Anekonda, Benjamin W. Thompson, Zachary S. Roberts, Daniel H. Moralejo, James E. Blevins

Arshad M. Khan, Ph.D.

This article, which includes novel unpublished data along with commentary and analysis,
focuses on approaches to link transcriptomic, proteomic, and peptidomic datasets mined from
brain tissue to the original locations within the brain that they are derived from using digital atlas
mapping techniques. We use, as an example, the transcriptomic, proteomic and peptidomic
analyses conducted in the mammalian hypothalamus. Following a brief historical overview, we
highlight studies that have mined biochemical and molecular information from the hypothalamus
and then lay out a strategy for how these data can be linked spatially to the mapped locations in a
canonical brain atlas ...


Regulation Of Juvenile Hormone Synthesis By 20-Hydroxyecdysone In The Yellow-Fever Mosquito, Aedes Aegypti, Maria Areiza May 2018

Regulation Of Juvenile Hormone Synthesis By 20-Hydroxyecdysone In The Yellow-Fever Mosquito, Aedes Aegypti, Maria Areiza

FIU Electronic Theses and Dissertations

In Aedes aegypti, development and reproduction are regulated by juvenile hormone III (JH). This master regulatory hormone is synthesized by the corpora allata (CA), a pair of endocrine glands with neural connections to the brain. JH titers are largely determined by the rate of biosynthetic activity of the CA and are regulated by inhibitory and stimulatory factors. Like JH, the ecdysteroid 20-hydroxyecdysone (20E) is a key hormonal regulator and has been proposed as an allatoregulator in other insects. However, its part in the regulation of JH biosynthesis of mosquitoes was unknown. The specific aims of this dissertation were to (1 ...


Regulation Of The Pi3-Kinase/Pten Signaling Pathway By Tgf-Β In Prostate Cancer Cells, Mawiyah Kimbrough-Allah May 2018

Regulation Of The Pi3-Kinase/Pten Signaling Pathway By Tgf-Β In Prostate Cancer Cells, Mawiyah Kimbrough-Allah

Electronic Theses & Dissertations Collection for Atlanta University & Clark Atlanta University

Transforming growth factor -β (TGF-β) plays an important role in the progression of prostate cancer. It acts as a tumor suppressor in normal epithelial cells but as a tumor promoter in advanced prostate cancer cells. The PI3-kinase pathway has been shown to play integral roles in many cellular processes including cell proliferation, survival, and cell migration in many cell types. PI3-kinase pathway mediates TGF-β effects on prostate cancer cell migration and invasion. Phosphatase and tensin homolog (PTEN), a tumor suppressor gene, inhibits PI3-kinase pathway and is frequently mutated in prostate cancers. In this present study, we investigated possible roles of ...


The Caspase Cascade During Hibernation In The Golden-Mantled Ground Squirrel, Spermophilus Lateralis, Michael David Treat May 2018

The Caspase Cascade During Hibernation In The Golden-Mantled Ground Squirrel, Spermophilus Lateralis, Michael David Treat

UNLV Theses, Dissertations, Professional Papers, and Capstones

In several human pathologies like heart attack, stroke, neurodegenerative diseases, and autoimmune disorders, widespread cell death, or apoptosis, is a major cause of organ dysfunction and death. Hibernating golden-mantled ground squirrels, Spermophilus lateralis, experience numerous conditions during the winter that are known to be pro-apoptotic in other mammal systems (e.g. extreme hypothermia, ischemia and reperfusion, acidosis, increased reactive oxygen species, bone and muscle disuse). However, studies suggest that hibernators may invoke a protective phenotype to limit widespread cell damage and loss during the hibernation season. Could regulating apoptosis provide protection against the harmful conditions experienced during the hibernation season ...


Ph Sensitivity Of Connexin 50 Hemichannels: H95 And Beyond, Leah Volk May 2018

Ph Sensitivity Of Connexin 50 Hemichannels: H95 And Beyond, Leah Volk

Biology Theses

Gap junction channels formed by connexin proteins are critical for the health and function of the vertebrate lens. It is important to understand how these channels are affected by pH because a pH gradient exists in lens tissue. Intracellular pH (pHi) is a regulator of gap junction coupling, and different connexins show different sensitivities to pHi. A “Particle-Receptor” model for pH-dependent channel closure involves the intramolecular interaction between the cytoplasmic tail of the connexin and a region near the mouth of the channel dependent on a highly conserved histidine residue at position 95. While this model explains the ...


Functional Studies Of The E. Coli Proc And A Putative Ortholog Mrub_1345, Mourin Azar, Dr. Lori Scott May 2018

Functional Studies Of The E. Coli Proc And A Putative Ortholog Mrub_1345, Mourin Azar, Dr. Lori Scott

Meiothermus ruber Genome Analysis Project

This project is part of the Meiothermus ruber genome analysis project, which uses the bioinformatics tools associated with the Guiding Education through Novel Investigation –Annotation Collaboration Toolkit (GENI-ACT) to predict gene function. We investigated the biological function of Escherichia coli and Meiothermus ruber proC genes using the complementation assay. In this research project, mutants of varying severity to the functional state of the protein were developed. The results showed that two or more amino acid deletions reduced or eliminated ProC function. Amino acid substitutions, on the other hand, were not severe enough to impact ProC function. Double and triple mutants ...


A Single Mechanism Of Biogenesis, Initiated And Directed By Piwi Proteins, Explains Pirna Production In Most Animals, Phillip D. Zamore, Ildar Gainetdinov, Cansu Colpan, Katharine Cecchini Apr 2018

A Single Mechanism Of Biogenesis, Initiated And Directed By Piwi Proteins, Explains Pirna Production In Most Animals, Phillip D. Zamore, Ildar Gainetdinov, Cansu Colpan, Katharine Cecchini

University of Massachusetts Medical School Faculty Publications

In animals, piRNAs guide PIWI-proteins to silence transposons and regulate gene expression. The mechanisms for making piRNAs have been proposed to differ among cell types, tissues, and animals. Our data instead suggest a single model that explains piRNA production in most animals. piRNAs initiate piRNA production by guiding PIWI proteins to slice precursor transcripts. Next, PIWI proteins direct the stepwise fragmentation of the sliced precursor transcripts, yielding tail-to-head strings of phased pre-piRNAs. Our analyses detect evidence for this piRNA biogenesis strategy across an evolutionarily broad range of animals including humans. Thus, PIWI proteins initiate and sustain piRNA biogenesis by the ...

Investigation Of Alcohol-Induced Changes In Hepatic Histone Modifications Using Mass Spectrometry Based Proteomics, Crystina Leah Kriss Apr 2018

Investigation Of Alcohol-Induced Changes In Hepatic Histone Modifications Using Mass Spectrometry Based Proteomics, Crystina Leah Kriss

Graduate Theses and Dissertations

Alcohol liver disease (ALD) is a major health concern throughout the world. Currently, in the United States, 17 million people suffer from alcoholism, of which 1.4 million people are receiving treatment [1, 2]. The link between ethanol metabolism, reactive oxygen species (ROS) and liver injury in ALD has been well characterized over the last couple decades [3-10]. Ethanol metabolism relies on the availability of the cofactor NAD+ for the oxidation of ethanol into acetate, consequently causing alterations in redox potential. Redox dysfunction within the mitochondria can affect multiple pathways important in maintaining cellular homeostasis. Chapter 1 provides an introduction ...

Killi-Data News (Winter), Tyrone Genade

Killifish Research Review

Valued readers, it is with a heavy heart that I inform you that this is the last issue of Killi-Data News. The good news is that we will be back as Killifish Research Review. The dissolution of Killi-Data International created a prob- lem: how can the newsletter of a defunct organization live on without that organization? But other additional problems were building in the background. The first issue numbered 15 pages. The previous issue was 28 pages. The number of killifish related papers is increasing while time on our end (the editorial team) is running out. It takes a lot ...

Killi-Data News (Fall), Tyrone Genade

Killifish Research Review

Many interesting papers have been published over the last three months. The large volume of papers coupled with the start of the new college semester (and the workload it brings) delayed this issue of Killi-Data News. But better late than never—or so I hope! In this issue Richard van der Laan provides an insightful review of the recent Aphanius papers as to their taxonomic implications and questions. The systematic issues he raises show the importance of the Molecular project: we need to get more samples of the various cyprinodontiforme families to resolve unsettled systematic and taxonomic issues. In the ...

Killifish Research Review

Over the last three months several interesting and exciting pa- pers have been published. By now most of you have heard the Nothobranchius fish poo news emanating from the Valenzano lab. That paper is reviewed and certainly has repercussions for the health of our captive fish. Polaçik et al have published interesting data with ramifications as to how we breed and incubate annual killifish. The big news in this issue is the paper from the Reznick lab which Jean Huber reviews. The contents of that paper goes to the heart of the question of just what a killifish is. The ...

Killifish Research Review

This is the fourth edition, and concluding issue of the first volume, of Killi-Data News and I am happy that it has been well received by readers. At 25 pages this issue is a bit thin- ner than the last but this is because we agreed to make the cut-off for submissions the 1 st of December so we could get this edition out by the New Year. This is an exciting edition full of new species descrip- tions and analyses that will keep taxonomists busy for years to come. Costa has given us two molecular phylogenies on Melanorivulus as ...

Early Epstein-Barr Virus Genomic Diversity And Convergence Toward The B95.8 Genome In Primary Infection, Eric R. Weiss, Susanna L. Lamers, Jennifer L. Henderson, Alexandre Melnikov, Mohan Somasundaran, Manuel Garber, Liisa K. Selin, Chad Nusbaum, Katherine Luzuriaga Jan 2018

Early Epstein-Barr Virus Genomic Diversity And Convergence Toward The B95.8 Genome In Primary Infection, Eric R. Weiss, Susanna L. Lamers, Jennifer L. Henderson, Alexandre Melnikov, Mohan Somasundaran, Manuel Garber, Liisa K. Selin, Chad Nusbaum, Katherine Luzuriaga

Garber Lab Publications

Over 90% of the world's population is persistently infected with Epstein-Barr virus. While EBV does not cause disease in most individuals, it is the common cause of acute infectious mononucleosis (AIM) and has been associated with several cancers and autoimmune diseases, highlighting a need for a preventive vaccine. At present, very few primary, circulating EBV genomes have been sequenced directly from infected individuals. While low levels of diversity and low viral evolution rates have been predicted for double-stranded DNA (dsDNA) viruses, recent studies have demonstrated appreciable diversity in common dsDNA pathogens (e.g., cytomegalovirus). Here, we report 40 full-length ...

In this project we investigated the biological function of the genes Mrub_1325, Mrub_1326, Mrub_1327, and Mrub_1328 (KEGG map number 02010). We predict these genes encode components of a Branched Chain Amino Acid ATP Binding Cassette (ABC) transporter: 1) Mrub_1325 (DNA coordinates 1357399-1358130 on the reverse strand) encodes the ATP binding domain; 2) Mrub_1326 (DNA coordinates 1358127-1359899 on the reverse strand) encodes the ATP-binding domain and permease domain; 3) Mrub_1327 (DNA coordinates 1359899-1360930 on the reverse strand) encodes a permease domain; and 4)Mrub_1328 (DNA coordinates 1711022-1712185 on the reverse strand) encodes the substrate binding domain. This system is not predicted ...
