CUREing cancer: Development and implementation of a molecular biology-focused course-based undergraduate research experience using a cancer cell culture model

Abstract

Many students in the sciences are interested in exploring research opportunities; however, the one-on-one faculty mentorship model often lacks the ability to supervise large numbers of students. An alternative mechanism for exposing undergraduate students to the research process is participation in a Course-based Undergraduate Research Experience (CURE). CUREs promote inclusivity in research, and provide structure for both students and faculty while engaging students in scientific discovery. This study describes a model for a CURE in cancer biology, and reports student outcomes. Students utilized bioinformatics to predict targets genes of miR-100, a microRNA that is differentially expressed in a cell culture model of breast cancer metastasis. Students were required to engage with primary literature to write a grant proposal for their target gene, and then were trained to perform basic molecular biology techniques to test their individual hypotheses. Additionally, the course integrated opportunities to troubleshoot experiments and present data to the group, and culminated in a publication style scientific report discussing the results of their individual research project. Students reported significantly increased confidence in executing various molecular biology techniques and research-related skills based on pre- and post-assessment surveys. Student feedback also indicated that they gained an understanding of primary literature, experimental design, and scientific writing as a result of the course. This study supports that CUREs can be an effective pedagogy for not only engaging larger groups of students in research, but also improving their confidence and skill set in the laboratory.
