An Arabidopsis Mutant Screen CURE for a Cell and Molecular Biology Laboratory Course part of CUREnet:CURE Collection
This CURE is designed from a crucial component of a chloroplast lipid signaling research project and has been implemented for a cell and molecular biology laboratory course at Michigan State University. The research laboratory generated an engineered plant line producing a lipid-derived plant hormone and mutagenized this line. The research question is "what transporters or receptors are involved in the hormone signaling transduction or perception processes?". Students form research hypotheses based on the research model, design experiments, perform experiments, collect and analyze data, make scientific arguments, and share their findings with the learning community. Specifically, the students culture the mutagenized plant population and select the desired mutant phenotypes, followed by genotyping the mutants and characterizing the mutants by basic biochemical approaches. Mathematics is also integrated into the course design. As the students studied the relevant genetic, molecular and biochemical concepts during this CURE, they use the core idea of information flow and data they generate in the lab to make claims about their mutant plants and support these claims with evidence and reasoning.

MCC: Malate Dehydrogenase CUREs Community part of CUREnet:CURE Collection
The Malate Dehydrogenase CUREs Community (MCC) project is designed to facilitate the adoption of effective, protein‐centric, Course Based Undergraduate Research Experiences (CUREs) into teaching labs at a wide variety of undergraduate serving institutions. (Primarily Undergraduate Institutions, Research Intensive Universities and Community Colleges) MCC coordinates and conducts pedagogical research into two major features of CUREs:1) their duration (whole semester versus 5‐6 week modules incorporated into a lab class), and 2) the impact of scientific collaboration between institutions (a key aspect of much modern research). Using validated assessment tools we seek to establish their effects on student confidence, persistence in STEM, and ability to design research experiments and interprete data. To facilitate faculty adoption of CURE approaches the project provides a number of resources. These focus on a variety of research areas related to Malate Dehydrogenase including mechanisms of catalysis and regulation, adaptation and evolution, cofactor specificity, folding and stability and interactions in metabolons. Resources include biologics, experimental protocols and assessment tools. The project also coordinates interactions between courses at different institutions to allow incorporation of scientific collaboration into CUREs. These collaborations also facilitate the use of more sophisticated experimental approaches and broaden the experimental scope of the CUREs.

Genomics Education Partnership part of CUREnet:CURE Collection
The goal of the Genomics Education Partnership is to provide opportunities for undergraduate students to participate in genomics research. GEP is a collaboration between a growing number of primarily undergraduate institutions, the Biology Dept and Genome Center of Washington University in St. Louis, and the Biology Dept at the University of Alabama. Participating undergraduates learn to take raw sequence data to high quality finished sequence, and to annotate genes and other features, leading to analysis of a question in genomics and research publication. GEP organizes research projects and provides training/collaboration workshops for PUI faculty and teaching assistants.

Neurogenetics Laboratory: Mapping a functional circuit for cold nociception in Drosophila part of CUREnet:Institutes:Alabama State University:Examples
Students will work in small groups to identify neural populations that may be involved in the Drosophila larval response to noxious cold. They will use the GAL4/UAS expression system to excite or inhibit neural populations and assess the impact of their manipulation on the larvae's behavioral response to cold. If a relevant neural population is identified, students will then identify (based on current literature) genes that are likely to be involved in neurite development and/or maintenance in that population. They will use mutations and/or RNA interference to disrupt the function of these genes in the population of interest and assess the effect of the disruption on neuronal morphology and larval behavior.

Exploring eukaryotic protein structure and post-translational modifications. part of CUREnet:Institutes:Bowie State University:Examples
This CURE will provide opportunity for students to think and act as researchers by using computational, biochemical, and bioanalytical techniques to examine tick antigen proteins. The CURE is designed as a lab for upper-level students who are taking or have taken a one-semester introductory biochemistry course, but two semesters would be even better. It could also be adapted for cell/molecular biology or (bio) analytical chemistry instrumentational analysis labs. It has been taught for classes ranging from 12-24 students. Ticks are notorious vectors of viral, protozoan, and bacterial diseases, including Lyme disease. While an anti-vector vaccine capable of protecting people from diseases transmitted by a particular tick species is an alluring goal, only one such anti-tick vaccine is currently available. This vaccine targets Bm86, a protein from the midgut of Rhipicephalus microplus, a cattle tick. Not only does the vaccine limit parasitism of the cattle by ticks, data suggests that it can also prevent transmission of tick-borne diseases including bovine anaplasmosis and babesiosis. However, similar vaccination approaches have not succeeded thus far against ticks that transmit diseases to humans, and little is known about the antibody response to the antigen, or about the protein itself. Since the protein's structure and function are unknown, the research goal of this CURE is to purify Bm86 using an insect cell/baculovirus expression system and characterize it, including domain structure and post-translational modifications (glycosylation sites). There are homologs to Bm86 in every sequenced tick species examined, and future CUREs will characterize some of the homologs including those in Ixodes scapularis, the tick that is mainly responsible for transmitting Lyme in the eastern US, and Haemaphysalis longicornis, the Asian longhorned tick, a newly-discovered invasive species in the area that also has significant disease-transmitting potential. By understanding the structure and post-translational modifications of this protein, we hope to gain a better understanding of how to make effective anti-tick vaccines, including those for humans, that may prevent transmission of Lyme disease. Importantly, the basic parameters of this CURE can be used to examine other proteins besides tick antigens. For example, during the pandemic, the CURE pivoted from the tick antigen to the SARS-CoV-2 nucleocapsid protein, which was also expressed in an insect cell system. Instead of characterizing glycosylation sites, we characterized phosphorylation sites. It's therefore possible to use this same framework for many different eukaryotic proteins that may be of research interest.

Characterizing the Aging Process Using Caenorhabditis elegans and Reverse Genetics part of CUREnet:Institutes:Community College of Rhode island:Examples
Using gene silencing (RNAi) in the nemotode C. elegans, students will identify genetic modifiers of proteins with roles in aging by reverse genetics. Specifically, students will analyze the effect of knocking down genes on the level of aging-related proteins tagged with fluorophores (GFP, RFP, etc.). Each group of students will use function-specific RNAi libraries (transcription factors, kinases, etc) already established in our lab. Furthermore, students will evaluate the effect of genetic modifiers on proteostasis and lifespan. In addition to becoming familiar with C. elegans work and appreciating the use of model organisms, the students will master microscopy, genetic crosses, gene silencing, and molecular and biochemical readout assays such as qPCR and immunoblotting.
