Co-creation and engagement in a DNA integrity cohort study.

Introduction: The partnership between a research community engagement team (CE Team) and a community advisory board (CAB) formed the basis for bidirectional communication in developing resources for participant recruitment in a DNA integrity study. Engaging with a minoritized community, this partnership focused on respect, accessibility, and expanded engagement. Methods: A ten-member CAB, working in two groups defined by meeting time convenience, provided insight and feedback to the CE Team in the creation of recruitment and consent materials, via an iterative design process in which one CAB group reviewed and enhanced materials, and the second group tested and refined them further. The continuous analysis of CE Team notes from CAB meetings captured information needed both for materials refinement and implementation of CAB-suggested activities. Results: The partnership resulted in the co-creation of recruitment and consent materials that facilitated the enrollment of 191 individuals into the study. The CAB encouraged and assisted in expanded engagement inclusive of community leaders. This broader engagement provided information about the DNA integrity study to community decision-makers as well as responded to questions and concerns about the research. The bidirectional communication between the CAB and the CE Team encouraged the researchers to consider topics and research interests related to the current study but also responsive to community concerns. Conclusions: The CAB helped the CE Team develop a better understanding of the language of partnership and respect. In this way, the partnership opened doors for expanded community engagement and effective communication with potential study participants.

A high-throughput 384-well CometChip platform reveals a role for 3-methyladenine in the cellular response to etoposide-induced DNA damage.

The Comet or single-cell gel electrophoresis assay is a highly sensitive method to measure cellular, nuclear genome damage. However, low throughput can limit its application for large-scale studies. To overcome these limitations, a 96-well CometChip platform was recently developed that increases throughput and reduces variation due to simultaneous processing and automated analysis of 96 samples. To advance throughput further, we developed a 384-well CometChip platform that allows analysis of ∼100 cells per well. The 384-well CometChip extends the capacity by 4-fold as compared to the 96-well system, enhancing application for larger DNA damage analysis studies. The overall sensitivity of the 384-well CometChip is consistent with that of the 96-well system, sensitive to genotoxin exposure and to loss of DNA repair capacity. We then applied the 384-well platform to screen a library of protein kinase inhibitors to probe each as enhancers of etoposide induced DNA damage. Here, we found that 3-methyladenine significantly increased levels of etoposide-induced DNA damage. Our results suggest that a 384-well CometChip is useful for large-scale DNA damage analyses, which may have increased potential in the evaluation of chemotherapy efficacy, compound library screens, population-based analyses of genome damage and evaluating the impact of environmental genotoxins on genome integrity.

Research Apprenticeship and Its Potential as a Distinct Model of Peer Research Practice.

BACKGROUND: Three models of peer research have emerged: advisory, employment, and partner. We propose a fourth model, the "research apprentice" prototype conceived as a postsecondary workforce development avenue for members of disadvantaged communities. OBJECTIVES: We introduce the research apprenticeship experience and its potential contributions to the fields of health equity and translational research. METHODS: Implementation of the research apprenticeship model within a survey research project. RESULTS: In this article, we 1) identify the model's distinctive qualities, 2) conceptualize an appropriate industry for graduates, 3) recognize its value for those with little access to postsecondary education, and 4) formulate a vision for contributing to health equity and translational research. CONCLUSIONS: The research apprenticeship holds potential to realize goals of capacity building, empowerment, and co-learning; generate educational progress and employment for participants; expand diversity in biomedical research; support two-directional co-learning between community and academia; and contribute to dismantling structural racism within the biomedical sciences.

Consolidating the Academic End of a Community-Based Participatory Research Venture to Address Health Disparities.

Although there is strong support for community engagement and community-based participatory research (CBPR) from public health entities, medical organizations, and major grant-funding institutions, such endeavors often face challenges within academic institutions. Fostering the interest, skills, and partnerships to undertake participatory research projects and truly impact the community requires an interdisciplinary team with the competencies and values to engage in this type of research. Discussed in this article is how a CBPR-focused team evolved at a southern university, with emphasis on the activities that supported group identity, contributed to its evolution, and positioned the group to speak with authority in promoting CBPR as a tool for addressing health disparities.
