Following testicular spermatogenesis, mammalian sperm continue to mature in a long epithelial tube known as the epididymis, which plays key roles in remodeling sperm protein, lipid, and RNA composition. To understand the roles for the epididymis in reproductive biology, we generated a single-cell atlas of the murine epididymis and vas deferens. We recovered key epithelial cell types including principal cells, clear cells, and basal cells, along with associated support cells that include fibroblasts, smooth muscle, macrophages and other immune cells. Moreover, our data illuminate extensive regional specialization of principal cell populations across the length of the epididymis. In addition to ...


Aspen Next Generation: Conversations From Southern Colorado And Northern New Mexico, Dan Binkley, Bill Romme 2020 Northern Arizona University

Aspen Next Generation: Conversations From Southern Colorado And Northern New Mexico, Dan Binkley, Bill Romme

Aspen Bibliography

Aspen trees and forests are especially important in the Rocky Mountains. Aspens add beauty to landscapes, foster high diversity and productivity of understory plants, provide for the habitat needs of many species of animals, and moderate fire behavior. There is a perception that aspen trees and stands are not regenerating well in southern Colorado and northern New Mexico; cohorts of trees younger than a few decades are scarce, at least in some areas. The next generation of aspen in the southern Rockies will be influenced by land use decisions, including harvesting, fire policy and management, and browsing by livestock and ...


Building The Interphase Nucleus: A Study On The Kinetics Of 3d Chromosome Formation, Temporal Relation To Active Transcription, And The Role Of Nuclear Rnas, Kristin N. Abramo 2020 University of Massachusetts Medical School

Building The Interphase Nucleus: A Study On The Kinetics Of 3d Chromosome Formation, Temporal Relation To Active Transcription, And The Role Of Nuclear Rnas, Kristin N. Abramo

GSBS Dissertations and Theses

Following the discovery of the one-dimensional sequence of human DNA, much focus has been directed on microscopy and molecular techniques to learn about the spatial organization of chromatin in a 3D cell. The development of these powerful tools has enabled high-resolution, genome-wide analysis of chromosome structure under many different conditions. In this thesis, I focus on how the organization of interphase chromatin is established and maintained following mitosis. Mitotic chromosomes are folded into helical loop arrays creating short and condensed chromosomes, while interphase chromosomes are decondensed and folded into a number of structures at different length scales ranging from loops ...


Beaver And Naked Mole Rat Genomes Reveal Common Paths To Longevity, Xuming Zhou, Elinor K. Karlsson, Vadim N. Gladyshev 2020 Harvard Medical School

Beaver And Naked Mole Rat Genomes Reveal Common Paths To Longevity, Xuming Zhou, Elinor K. Karlsson, Vadim N. Gladyshev

University of Massachusetts Medical School Faculty Publications

Long-lived rodents have become an attractive model for the studies on aging. To understand evolutionary paths to long life, we prepare chromosome-level genome assemblies of the two longest-lived rodents, Canadian beaver (Castor canadensis) and naked mole rat (NMR, Heterocephalus glaber), which were scaffolded with in vitro proximity ligation and chromosome conformation capture data and complemented with long-read sequencing. Our comparative genomic analyses reveal that amino acid substitutions at "disease-causing" sites are widespread in the rodent genomes and that identical substitutions in long-lived rodents are associated with common adaptive phenotypes, e.g., enhanced resistance to DNA damage and cellular stress. By ...


Wild Mice With Different Social Network Sizes Vary In Brain Gene Expression, Patricia C. Lopes, Barbara König 2020 Chapman University

Wild Mice With Different Social Network Sizes Vary In Brain Gene Expression, Patricia C. Lopes, Barbara König

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Background

Appropriate social interactions influence animal fitness by impacting several processes, such as mating, territory defense, and offspring care. Many studies shedding light on the neurobiological underpinnings of social behavior have focused on nonapeptides (vasopressin, oxytocin, and homologues) and on sexual or parent-offspring interactions. Furthermore, animals have been studied under artificial laboratory conditions, where the consequences of behavioral responses may not be as critical as when expressed under natural environments, therefore obscuring certain physiological responses. We used automated recording of social interactions of wild house mice outside of the breeding season to detect individuals at both tails of a distribution ...


Insights From Population Genomics To Enhance And Sustain Biological Control Of Insect Pests, Arun Sethuraman, Fredric J. Janzen, David W. Weisrock, John J. Obrycki 2020 California State University, San Marcos

Insights From Population Genomics To Enhance And Sustain Biological Control Of Insect Pests, Arun Sethuraman, Fredric J. Janzen, David W. Weisrock, John J. Obrycki

Ecology, Evolution and Organismal Biology Publications

Biological control—the use of organisms (e.g., nematodes, arthropods, bacteria, fungi, viruses) for the suppression of insect pest species—is a well-established, ecologically sound and economically profitable tactic for crop protection. This approach has served as a sustainable solution for many insect pest problems for over a century in North America. However, all pest management tactics have associated risks. Specifically, the ecological non-target effects of biological control have been examined in numerous systems. In contrast, the need to understand the short- and long-term evolutionary consequences of human-mediated manipulation of biological control organisms for importation, augmentation and conservation biological control ...


Simultaneous Epigenetic Perturbation And Genome Imaging Reveal Distinct Roles Of H3k9me3 In Chromatin Architecture And Transcription, Ying Feng, Yao Wang, Xiangnan Wang, Xiaohui He, Chen Yang, Ardalan Naseri, Thoru Pederson, Jing Zheng, Shaojie Zhang, Xiao Xiao, Wei Xie, Hanhui Ma 2020 East China University of Science and Technology

Simultaneous Epigenetic Perturbation And Genome Imaging Reveal Distinct Roles Of H3k9me3 In Chromatin Architecture And Transcription, Ying Feng, Yao Wang, Xiangnan Wang, Xiaohui He, Chen Yang, Ardalan Naseri, Thoru Pederson, Jing Zheng, Shaojie Zhang, Xiao Xiao, Wei Xie, Hanhui Ma

University of Massachusetts Medical School Faculty Publications

Despite the long-observed correlation between H3K9me3, chromatin architecture and transcriptional repression, how H3K9me3 regulates genome higher-order organization and transcriptional activity in living cells remains unclear. Here we develop EpiGo (Epigenetic perturbation induced Genome organization)-KRAB to introduce H3K9me3 at hundreds of loci spanning megabases on human chromosome 19 and simultaneously track genome organization. EpiGo-KRAB is sufficient to induce de novo heterochromatin-like domain formation, which requires SETDB1, a methyltransferase of H3K9me3. Unexpectedly, EpiGo-KRAB induced heterochromatin-like domain does not result in widespread gene repression except a small set of genes with concurrent loss of H3K4me3 and H3K27ac. Ectopic H3K9me3 appears to spread ...

Articles, Abstracts, and Reports

We present a consensus atlas of the human brain transcriptome in Alzheimer's disease (AD), based on meta-analysis of differential gene expression in 2,114 postmortem samples. We discover 30 brain coexpression modules from seven regions as the major source of AD transcriptional perturbations. We next examine overlap with 251 brain differentially expressed gene sets from mouse models of AD and other neurodegenerative disorders. Human-mouse overlaps highlight responses to amyloid versus tau pathology and reveal age- and sex-dependent expression signatures for disease progression. Human coexpression modules enriched for neuronal and/or microglial genes broadly overlap with mouse models of AD ...


Anti-Crispr Proteins: Applications In Genome Engineering, Jooyoung Lee 2020 University of Massachusetts Medical School

Anti-Crispr Proteins: Applications In Genome Engineering, Jooyoung Lee

GSBS Dissertations and Theses

Clustered, regularly interspaced, short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) constitute a bacterial and archaeal adaptive immune system. The ongoing arms race between prokaryotic hosts and their invaders such as phages led to the emergence of anti-CRISPR proteins as countermeasures against the potent antiviral defense. Since the first examples of anti-CRISPRs were shown in a subset of CRISPR-Cas systems, we endeavored to uncover these naturally-occurring inhibitors that inactivate different types of CRISPR-Cas systems. In the first part of my thesis, we have identified and characterized Type II anti-CRISPR proteins that inactivate several Cas9 orthologs. We share mechanistic insights into anti-CRISPR ...

Articles, Abstracts, and Reports

Granulocyte-monocyte colony stimulating factor (GM-CSF) is used as an adjuvant in various clinical and preclinical studies with contradictory results. These were attributed to opposing effects of GM-CSF on the immune or myeloid systems of the treated patients or to lack of optimal dosing regimens. The results of the present study point to inter-tumor heterogeneity as a possible mechanism accounting for the contrasting responses to GM-CSF incorporating therapies. Employing xenograft models of human melanomas in nude mice developed in our lab, we detected differential functional responses of melanomas from different patients to GM-CSF both in vitro as well as in vivo ...


A Strategic Plan To Thread Genomics Competencies Into Undergraduate Curriculum, Holly Mathis 2020 University of Missouri-St. Louis

A Strategic Plan To Thread Genomics Competencies Into Undergraduate Curriculum, Holly Mathis

Dissertations

Problem: Genomics in undergraduate nursing education has experienced slow adoption in the United States. Various approaches have been proposed but do not address barriers to successful implementation.

Methods: A strategic plan was developed to increase the amount of genetics and genomic content in the curriculum of an undergraduate nursing program. A gap analysis was performed on the curriculum revealing a paucity of content. A SWOT analysis informed the strategic plan, which included a faculty education program using the ANA/ISONG’s Essentials of Genetic and Genomic Nursing: Competencies, Curricula Guidelines and Outcome Indicators (2nd ed.) (2009) as a foundation ...


Epigenetics A Decolonizing Science, Wade Paul 2020 The University of Western Ontario

Epigenetics A Decolonizing Science, Wade Paul

Electronic Thesis and Dissertation Repository

Epigenetics is the study of gene expression that does not entail alterations to the actual DNA. Decolonization is a theoretical and political movement that seeks to deconstruct colonial institutions and ideologies and reconstruct new and balanced approaches that accept and respect Indigenous worldviews. This project studies the decolonizing potential of epigenetics. Using genealogy as the method, the study establishes a long history of reductionist and deterministic thought that shaped the study of genetic science. Particular instances like thrift gene theory are explored to highlight how genetic explanations have been detrimental to the health and wellbeing of Indigenous people and illustrate ...

Plant cell growth involves a complex interplay among cell-wall expansion, biosynthesis, and, in specific tissues, secondary cell wall (SCW) deposition, yet the coordination of these processes remains elusive. Cotton fiber cells are developmentally synchronous, highly elongated, and contain nearly pure cellulose when mature. Here, we report that the transcription factor GhTCP4 plays an important role in balancing cotton fiber cell elongation and wall synthesis. During fiber development the expression of miR319 declines while GhTCP4 transcript levels increase, with high levels of the latter promoting SCW deposition. GhTCP4 interacts with a homeobox-containing factor, GhHOX3, and repressing its transcriptional activity. GhTCP4 and ...


Sars-Cov-2 Spike Protein Variant D614g Increases Infectivity And Retains Sensitivity To Antibodies That Target The Receptor Binding Domain., Leonid Yurkovetskiy, Thomas Nyalile, Yetao Wang, William E.

COVID-19 Publications by UMMS Authors

Virus genome sequence variants that appear over the course of an outbreak can be exploited to map the trajectory of the virus from one susceptible host to another. While such variants are usually of no functional significance, in some cases they may allow the virus to transmit faster, change disease severity, or confer resistance to antiviral therapies. Since the discovery of SARS-CoV-2 as the cause of COVID-19, the virus has spread around the globe, and thousands of SARS-CoV-2 genomes have been sequenced. The rate of sequence variation among SARS-CoV-2 isolates is modest for an RNA virus but the enormous number ...


Chromosome-Scale Assembly Of The Coral Endosymbiont Symbiodinium Microadriaticum Genome Provides Insight Into The Unique Biology Of Dinoflagellate Chromosomes, Ankita Nand, Ye Zhan, Octavio R. Salazar, Manuel Aranda, Christian R. Voolstra, Job Dekker 2020 University of Massachusetts Medical School

University of Massachusetts Medical School Faculty Publications

Dinoflagellates are major primary producers in the world’s oceans, the cause of harmful algal blooms, and endosymbionts of marine invertebrates. Much remains to be understood about their biology including their peculiar crystalline chromosomes. Here we used Hi-C to order short read-based sub-scaffolds into 94 chromosome-scale scaffolds of the genome of the coral endosymbiont Symbiodinium microadriaticum. Hi-C data show that chromosomes are folded as linear rods within which loci separated by up to several Mb are highly packed. Each chromosome is composed of a series of structural domains separated by boundaries. Genes are enriched towards the ends of chromosomes and ...

Biological Sciences Faculty Publications

The microRNAs (miRNAs) are important regulators of gene expression. In this study, we provide evidence for the first time to show that rickettsial pathogen Anaplasma phagocytophilum infection results in the down-regulation of tick microRNA-133 (miR-133), to induce Ixodes scapularis organic anion transporting polypeptide (isoatp4056) gene expression critical for this bacterial survival in the vector and for its transmission to the vertebrate host. Transfection studies with recombinant constructs containing transcriptional fusions confirmed binding of miR-133 to isoatp4056 mRNA. Treatment with miR-133 inhibitor resulted in increased bacterial burden and isoatp4056 expression in ticks and tick cells. In contrast, treatment with miR-133 mimic ...

Secretion Of Proteins And Antibody Fragments From Transiently Transfected Endothelial Progenitor Cells, Loree Heller, Reynald Thinard, Melanie Chevalier, Sezgi Arpag, Yu Jing, Ruth Greferath, Richard Heller, Claude Nicolau

Bioelectrics Publications

In neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, multiple sclerosis and amyotrophic lateral sclerosis, neuroinflammation can lead to blood-brain barrier (BBB) breakdown. After intravenous or intra-arterial injection into mice, endothelial progenitor cells (EPCs) home to the damaged BBB to promote neurovascular repair. Autologous EPCs transfected to express specific therapeutic proteins offer an innovative therapeutic option. Here, we demonstrate that EPC transfection by electroporation with plasmids encoding the reporter protein GFP or an anti-beta-amyloid antibody fragment (Fab) leads to secretion of each protein. We also demonstrate the secreted anti-beta-amyloid Fab protein functions in beta-amyloid aggregate solubilization.


Interrelationships Among Monorchiid Trematodes With Special Emphasis On Some Northwestern Atlantic Genera, Apryle Panyi 2020 The University of Southern Mississippi

Interrelationships Among Monorchiid Trematodes With Special Emphasis On Some Northwestern Atlantic Genera, Apryle Panyi

Master's Theses

The Monorchiidae Odhner, 1911 is a cosmopolitan family of flukes (Trematoda: Digenea) comprising species that parasitize the digestive tract of estuarine and marine fishes as adults. Compared with other oceans, recent morphological or molecular taxonomic work conducted on monorchiid species from the northwestern Atlantic Ocean has been sparse (Manter, 1931; Overstreet, 1969; Andres et al., 2018; Wee et al., 2018, 2019, 2020). Therefore, the present work investigated the interrelationships of some monorchiids from the northwestern Atlantic Ocean with emphasis on several genera and investigated if Lasiotocus minutus (Manter, 1931) Thomas, 1959 constitutes a complex of cryptic species. New morphological and ...


Genomics Of Evolutionary Novelty In Hybrids And Polyploids, Gonzalo Nieto Feliner, Josep Casacuberta, Jonathan F. Wendel 2020 Real Jardín Botánico

Genomics Of Evolutionary Novelty In Hybrids And Polyploids, Gonzalo Nieto Feliner, Josep Casacuberta, Jonathan F. Wendel

Ecology, Evolution and Organismal Biology Publications

It has long been recognized that hybridization and polyploidy are prominent processes in plant evolution. Although classically recognized as significant in speciation and adaptation, recognition of the importance of interspecific gene flow has dramatically increased during the genomics era, concomitant with an unending flood of empirical examples, with or without genome doubling. Interspecific gene flow is thus increasingly thought to lead to evolutionary innovation and diversification, via adaptive introgression, homoploid hybrid speciation and allopolyploid speciation. Less well understood, however, are the suite of genetic and genomic mechanisms set in motion by the merger of differentiated genomes, and the temporal scale ...

Virology Papers

Multiple sclerosis (MS) is the most common autoimmune disorder affecting the central nervous system. Epstein-Barr virus (EBV) is a causative agent for infectious mononucleosis (IM) that is associated with MS pathogenesis. However, the exact mechanism by which EBV, specifically in IM, increases the risk for MS remains unknown. EBV immortalizes primary B lymphocytes in vitro and causes excessive B lymphocyte proliferation in IM in vivo. In asymptomatic carriers, EBV-infected B lymphocytes still proliferate to certain degrees, the process of which is tightly controlled by the host immune systems. Experimental autoimmune encephalomyelitis (EAE) mimics key features of MS in humans and ...
