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.

Population & Community Ecology part of CUREnet:CURE Collection
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.

Molecular Parasitology part of CUREnet:CURE Collection
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.

Isolation and characterization of antibiotic-producing soil bacteria part of CUREnet:Institutes:NC Central University:Examples
One of the biggest threat in hospitals is the rising cases of people who harbor antibiotic-resistant bacterial strains. Therefore, it is critical to find and characterize novel antibiotics to combat the resistant strains. Most of the antibiotics used in healthcare settings come from anti-biotic producing bacteria and fungi found in the soil. The goal of this CURE will be to isolate antibiotic-producing bacteria and fungi from the soil in the local area, and to determine the chemistry of the antibiotics. An extension of the project will be to determine how the presence of antibiotic-producing microbes affect other organisms resident in the soil, as it is unclear as to why microbes use energy to produce antibiotic factors.

Synthesis of the Intermediate of a Catalytic Reaction: An NHC-Stabilized, First-Row Transition Metal Complex part of CUREnet:Institutes:Other Institutes (2019-2020):Examples
The advanced synthesis laboratory course object allows students to study the synthesis, purification, and characterizations of a new diamagnetic organometallic complex of a first-row transition metal. The air-stable complex is stabilized by an N-heterocyclic carbene spectator ligand. It also bears an actor ligand and therefore, is potentially a reactive intermediate of a catalytic reaction. The synthesis of a reactive intermediate is the key to elucidate the mechanism of catalysis. The instructor chooses the first-row transition metal and the actor ligand based on his or her interests. The CURE starts from an NHC-ligated complex that does not bear this actor ligand but is otherwise similar. In our CURE, an anion ligand-replacement reaction was used to install the actor ligand, but an instructor may choose other approaches. The students will evaluate their results by standard spectroscopic analyses using UV-vis, FT-IR, and proton NMR (60 MHz or above) analysis.

Analysis of the effects of protein-protein interactions on signaling through a team-based undergraduate biochemistry laboratory course part of CUREnet:CURE Collection
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.

BASIL (Biochemistry Authentic Scientific Inquiry Laboratory) part of CUREnet:CURE Collection
This curriculum from the BASIL (Biochemistry Authentic Scientific Inquiry Laboratory) biochemistry consortium aims to get students to transition from thinking like students to thinking like scientists. Students will analyze proteins with known structure but unknown function using computational analyses and wet-lab techniques. BASIL is designed for undergraduate biochemistry lab courses, but can be adapted to first year (or even high school) settings, as well as upper-level undergraduate or graduate coursework. It is targeted to students in biology, biochemistry, chemistry, or related majors. Further details about the BASIL biochemistry consortium can be found on the BASIL blog, http://basiliuse.blogspot.com/ The curriculum is flexible and can be adapted to match the available facilities, the strengths of the instructor and the learning goals of a course and institution. These lessons are often used as part of upper-level laboratory coursework with at least one semester of biochemistry as a pre-requisite or co-requisite. The lab has been designed for classes ranging from 10-24 students (working in teams of two or three) per lab section. This lesson can be adapted to laboratory courses for introductory biology, cell and molecular biology, or advanced biology labs.

Analyzing datasets in ecology and evolution to teach the nature and process of science part of CUREnet:CURE Collection
This quarter-long project forms the basis of a third-year course for majors and nonmajors at the University of Washington, Bothell called Science Methods and Practice. Students use databases to identify novel research questions, and extract data to test their hypotheses. They frame the question with primary literature, address the questions with inferential statistics, and discuss the results with more primary literature. The product is a scientific paper; each step of the process is scaffolded and evaluated. Given time limitations, we avoid devoting time to data collection; instead, we sharpen students' ability to make sense of a large body of quantitative data, a situation they may rarely have encountered. We treat statistics with a strictly conceptual, pragmatic, and abbreviated approach; i.e., we ask students to know which basic test to choose to assess a linear relationship vs. a difference between two means. We stress the need for a normal distribution in order to use these tests, and how to interpret the results; we leave the rest for stats courses, and we do not teach the mathematics. This approach proves beneficial even to those who have already had a statistics course, because it is often the first time they make decisions about applying statistics to their own research questions. We incorporate peer review and collaborative work throughout the quarter. We form collaborative groups around the research questions they ask, enabling them to share primary literature they find, and preparing them well to review each other's writing. We encourage them to cite each other's work. They write formal peer reviews of each other's papers, and they submit their final paper with a letter-to-the-editor highlighting how their research has addressed previous feedback. A major advantage of this course is that an instructor can easily modify it to suit any area of expertise. Students have worked with data about how a snail's morphology changes in response to its environment (Price, 2012), how students understand genetic drift (Price et al. 2014), maximum body size in the fossil record (Payne et al. 2008), range shifts (Ettinger et al. 2011), and urban crop pollination (Waters and Clifford 2014).

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.

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.
