Student Perceptions of Undergraduate Research At Fort Hays State University

Undergraduate Research is becoming an increasingly important aspect of all academic areas in universities today, and as a result an effort must be made to underand how students feel about conducting undergraduate research. Literature suggests that students are aware of the benefits to be gained from conducting research, but there are a variety of factors holding them back from actually doing so. This particular study aimed to examine the benefits students feel they receive from conducting research as well as examine how the students feel about the availability of research opportunities at a Midwestern, predominantly undergraduate institution, Fort Hays State University. Five hundred seventy-six students responded to an e-mail survey. Results reflected that the majority of students have conducted research in some capacity. Students who had conducted research felt overwhelmingly positive about the benefits they received with regard to an increase in their understanding, an increase in their skills/abilities, and an increase in their awareness of various aspects of the research process, and an increase in their confidence and qualifications in conducting research. Students seemed very satistied with their research opportunities. Also, students recornized that a variety of personal qualities are impacted through the process of research. Similar to the literature, though, a majority of students did not feel research was for them. Further understanding the motivations for student research will help mitigate this, and provide insight into what can be done to influence students to conduct more research. Furthermore, as a university, FHSU must strive to maintain and increase research opportunities. FHSU must research why faculty engage in research with students, and try to utilize this to further enhance the experiences for both students and faculty

Inclusion Body Myositis: Laser Microdissection Reveals Differential Up-Regulation of IFN-γ Signaling Cascade in Attacked versus Nonattacked Myofibers

Sporadic inclusion body myositis (IBM) is a muscle disease with two separate pathogenic components, degeneration and inflammation. Typically, nonnecrotic myofibers are focally surrounded and invaded by CD8+ T cells and macrophages. Both attacked and nonattacked myofibers express high levels of human leukocyte antigen class I (HLA-I) molecules, a prerequisite for antigen presentation to CD8+ T cells. However, only a subgroup of HLA-I+ myofibers is attacked by immune cells. By using IHC, we classified myofibers from five patients with sporadic IBM as attacked (AIBM) or nonattacked (NIBM) and isolated the intracellular contents of myofibers separately by laser microdissection. For comparison, we isolated myofibers from control persons (HCTRL). The samples were analyzed by microarray hybridization and quantitative PCR. HLA-I up-regulation was observed in AIBM and NIBM, whereas HCTRL were negative for HLA-I. In contrast, the inducible chain of the interferon (IFN) γ receptor (IFNGR2) and several IFN-γ–induced genes were up-regulated in AIBM compared with NIBM and HCTRL fibers. Confocal microscopy confirmed segmental IFNGR2 up-regulation on the membranes of AIBM, which positively correlated with the number of adjacent CD8+ T cells. Thus, the differential up-regulation of the IFN-γ signaling cascade observed in the attacked fibers is related to local inflammation, whereas the ubiquitous HLA-I expression on IBM muscle fibers does not require IFNGR expression

GATA-3 is required for early T lineage progenitor development

Most T lymphocytes appear to arise from very rare early T lineage progenitors (ETPs) in the thymus, but the transcriptional programs that specify ETP generation are not completely known. The transcription factor GATA-3 is required for the development of T lymphocytes at multiple late differentiation steps as well as for the development of thymic natural killer cells. However, a role for GATA-3 before the double-negative (DN) 3 stage of T cell development has to date been obscured both by the developmental heterogeneity of DN1 thymocytes and the paucity of ETPs. We provide multiple lines of in vivo evidence through the analysis of T cell development in Gata3 hypomorphic mutant embryos, in irradiated mice reconstituted with Gata3 mutant hematopoietic cells, and in mice conditionally ablated for the Gata3 gene to show that GATA-3 is required for ETP generation. We further show that Gata3 loss does not affect hematopoietic stem cells or multipotent hematopoietic progenitors. Finally, we demonstrate that Gata3 mutant lymphoid progenitors exhibit neither increased apoptosis nor diminished cell-cycle progression. Thus, GATA-3 is required for the cell-autonomous development of the earliest characterized thymic T cell progenitors

Alliance of Genome Resources Portal: unified model organism research platform

The Alliance of Genome Resources (Alliance) is a consortium of the major model organism databases and the Gene Ontology that is guided by the vision of facilitating exploration of related genes in human and well-studied model organisms by providing a highly integrated and comprehensive platform that enables researchers to leverage the extensive body of genetic and genomic studies in these organisms. Initiated in 2016, the Alliance is building a central portal (www.alliancegenome.org) for access to data for the primary model organisms along with gene ontology data and human data. All data types represented in the Alliance portal (e.g. genomic data and phenotype descriptions) have common data models and workflows for curation. All data are open and freely available via a variety of mechanisms. Long-term plans for the Alliance project include a focus on coverage of additional model organisms including those without dedicated curation communities, and the inclusion of new data types with a particular focus on providing data and tools for the non-model-organism researcher that support enhanced discovery about human health and disease. Here we review current progress and present immediate plans for this new bioinformatics resource

The Gene Ontology knowledgebase in 2023

The Gene Ontology (GO) knowledgebase (http://geneontology.org) is a comprehensive resource concerning the functions of genes and gene products (proteins and noncoding RNAs). GO annotations cover genes from organisms across the tree of life as well as viruses, though most gene function knowledge currently derives from experiments carried out in a relatively small number of model organisms. Here, we provide an updated overview of the GO knowledgebase, as well as the efforts of the broad, international consortium of scientists that develops, maintains, and updates the GO knowledgebase. The GO knowledgebase consists of three components: (1) the GO-a computational knowledge structure describing the functional characteristics of genes; (2) GO annotations-evidence-supported statements asserting that a specific gene product has a particular functional characteristic; and (3) GO Causal Activity Models (GO-CAMs)-mechanistic models of molecular "pathways" (GO biological processes) created by linking multiple GO annotations using defined relations. Each of these components is continually expanded, revised, and updated in response to newly published discoveries and receives extensive QA checks, reviews, and user feedback. For each of these components, we provide a description of the current contents, recent developments to keep the knowledgebase up to date with new discoveries, and guidance on how users can best make use of the data that we provide. We conclude with future directions for the project

Multi-messenger searches via IceCube’s high-energy neutrinos and gravitational-wave detections of LIGO/Virgo

We summarize initial results for high-energy neutrino counterpart searches coinciding with gravitational-wave events in LIGO/Virgo\u27s GWTC-2 catalog using IceCube\u27s neutrino triggers. We did not find any statistically significant high-energy neutrino counterpart and derived upper limits on the time-integrated neutrino emission on Earth as well as the isotropic equivalent energy emitted in high-energy neutrinos for each event
