Genetic analysis in model systems using bioinformatic approaches provides a rich context for a concrete and conceptual understanding of gene structure and function. With the intent to engage students in research and explore disease biology utilizing the nematode Caenorhabditis elegans model, we developed a semester-long course-based undergraduate research experience (CURE) in a hybrid (online/in-person) learning environment—the gene-editing and evolutionary nematode exploration CURE (GENE-CURE). Using a combination of bioinformatic and molecular genetic tools, students performed structure-function analysis of disease-associated variants of uncertain significance (VUS) in human orthologs. With the aid of a series of workshop-style research sessions, students worked in teams …
An Evolutionary Comparative Study Of Congenital Stationary Night Blindness-Associated Trpm1 Genetic Variants Of Uncertain Significance In Horses And Humans Utilizing Caenorhabditis Elegans, Gabrielle Davis
Theses
Congenital stationary night blindness (CSNB) is a heterogeneous collection of genetic diseases affecting the eyes and vision in horses and humans. Current research has implicated several genetic mutations impacting different genes involved in phototransduction and signal transmission, including TRPM1. In horses, genetic mutations in TRPM1 also result in a leopard spotting pattern or leopard complex. The goal of this study is to examine the potential impact of CSNB associated TRPM1 missense variants of uncertain significance (VUS). Previous research in Caenorhabditis elegans have revealed an orthologous TRPM1 gene known as gon-2 that allows for comparative studies. The evolutionary relationship of …
Reverse Genetics: Downregulating Chk-1 And Fasn-1 In The Gonads Of C. Elegans, Sam Thompson
Reverse Genetics: Downregulating Chk-1 And Fasn-1 In The Gonads Of C. Elegans, Sam Thompson
Undergraduate Theses
Despite its widespread use in research, the model organism C. elegans has several biological processes like gonadal development with potentially unexplored genetic regulators. Previous transcriptome analysis has identified several genes that are upregulated in a specific tissue or sex during the development of the somatic gonad in C. elegans (Kroetz et al. 2015) that have not been previously connected to this process. Of these genes, this research is concerned with chk-1 and fasn-1. Abrogating the expression of these genes in gonadal tissue during gonadogenesis could cause a change in phenotype for affected C. elegans that would aid in understanding these …
Genome Engineering To Create Dominant Alleles In Caenorhabditis Elegans Using Crispr-Cas9 Technology, Abrar Sulaimani
Genome Engineering To Create Dominant Alleles In Caenorhabditis Elegans Using Crispr-Cas9 Technology, Abrar Sulaimani
Graduate School of Biomedical Sciences Theses and Dissertations
Many investigators have being using CRISPR-Cas9 as a method of genome engineering because it is easy, accurate and fast. This technique has been used to modify the genomes of a wide variety of organisms, including the nematode Caenorhabditis elegans (C. elegans). The short life cycle and ease of introducing exogenous plasmids make C. elegans an ideal system for advancing this technique. My thesis had two aims that focused on developing methods to create dominant alleles in C. elegans. Genetic modifications like precise deletion and insertions into a locus of chromosome are technically challenging. Additionally, although there are several ways of …
