Molecular Parasitology
Swati Agrawal, University of Mary Washington
Embedding inquiry driven research in undergraduate courses allows integration of core concepts and competencies necessary scientific thinking and develop lab skills. These are critical skill for undergraduates to be successful in science careers and for admission into graduate school. However, there are only a handful of examples of collaborative CUREs in Biology where students have an opportunity to connect with a network of researchers outside of their own institution, and none in the field of parasitology. In Spring 2021, we piloted a mini-CURE where student groups from University of Mary Washington and Georgia State University collaboratively completed research projects as part of a research-intensive course on Molecular Parasitology. The benefits of this approach were immediately obvious as students interacted across institutions, learned from each other's disciplinary expertise while informing their own research with data collected by their collaborators. It provided enrichment to the course by adding networking opportunities as well as cross-disciplinary knowledge sharing. We present here our CURE model as a way for other educators to design and implement similar cross-institutional inter-disciplinary CUREs that can be modified to align with their research expertise.

Population & Community Ecology
Cascade Sorte, University of California-Irvine
Students in a Population and Community Ecology class participate in coastal marine research focused on understanding factors determining population sizes and community interactions, particularly in the context of species that appear to be shifting their ranges with climate change. Students participate in all aspects of the research from making observations and collecting data in the field to defining questions, stating hypothesis, designing and completing statistical analysis, and interpreting and presenting results. The outcomes are a research proposal, research paper, and poster presentation. All are intended to be at a level appropriate for use as a writing sample or presentation at undergraduate conferences. Results are incorporated into the ongoing research project led by the course instructor and graduate student teaching assistant.

Community Flood Risk Assessment from Rising/Surging Seas Project
Kevin Kupietz, Elizabeth City State University
Globally 634 million people, 10% of the world's population, live in coastal areas less than 10 meters above sea level. According to 2010 census data, 123 million people, 39% of the United States population, live in coastal counties with an estimated increase to this number by 8% in the 2020 census. As natural disasters have been seen to increase in frequency and severity in the past five years coupled with expected sea rises from climate change it is important that anyone involved with the safety and resiliency planning of their organization/community have an understanding of how to scientifically assess risk from flooding in order to mitigate and recover from the effects. This project allows students the ability to develop skills to utilize computer modeling systems and to apply the data to real world communities in examining risk to structures as well as different groups in the community.

An Arabidopsis Mutant Screen CURE for a Cell and Molecular Biology Laboratory Course
Jinjie Liu, Michigan State University
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.

Analysis of the effects of protein-protein interactions on signaling through a team-based undergraduate biochemistry laboratory course
Daniela Fera, Swarthmore College
We developed a research-based laboratory course centered on a biological problem involving the B-Raf kinase, specifically the mutant that is commonly found in melanomas. One of the major goals of the project for the students is to generate mutants to determine whether a particular region of the B-Raf protein is critical for the interaction with MEK kinase, a downstream target in the pathway. Students analyze the published B-Raf-MEK crystal structure and choose a mutation to generate in B-Raf or MEK that might alter the dissociation constant (KD) of the complex. They design primers, perform PCR to generate their desired mutant, transform and purify the resulting DNA, express the DNA in E. coli, and purify the protein, all before characterizing it. Characterizing the mutant proteins consist of performing basic pull-downs, western blots, spectroscopic absorbance assays, and biolayer interferometry for binding kinetics. Students also engage in group meeting presentations and journal clubs in which they discuss their work and related primary literature, respectively. Group meeting and journal club discussions provide a forum for students to come up with new ideas to analyze their results, or for future work. Students summarize key results in a final presentation and paper, and develop a research proposal based on their work. Data that students obtain from their mutants provide evidence of the importance of a binding region for B-Raf-MEK complex formation, as well as downstream phosphorylation events. Such data will inform future drug discovery programs, as well as form the foundation for students' work in the course the following year. Because working with mutants can result in unpredictable data and results, students sometimes have to adjust their protocols and repeat experiments. Thus, the CURE format of this course also gives students an opportunity to learn to troubleshoot when things do not work as expected, which helps them learn resiliency in science.

Characterizing the Aging Process Using Caenorhabditis elegans and Reverse Genetics
Joslyn Mills, Brown University
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.

Neurogenetics Laboratory: Mapping a functional circuit for cold nociception in Drosophila
Sarah Clark, Georgia State University
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 the Structure-Function Relationship in RNA Biochemistry

Resequencing of Commercial Microorganisms
Jessica Kaufman, Endicott College
Students choose a probiotic pill or product with labeling that indicates the species and strain of bacteria in the product. Products are chosen so that a high quality reference genome sequence is available on NCBI. After DNA isolation and library preparation, high-quality student samples are pooled for next-gen sequencing on an Illumina MiSeq. The following semester, students in the required bioinformatics course will analyze the FASTQ files from the NGS run with a simple variant call workflow on usegalaxy.org. Then, each student will use a R Shiny app developed for this CURE to convert the VCF output from Galaxy to a FASTA file for an assigned gene in the resequenced genome. Students will complete their research experience by submitting the FASTA file to the NCBI Nucleotide Database.

MCC: Malate Dehydrogenase CUREs Community
Ellis Bell, University of San Diego
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.
