Item type:Publication, Bridging the Gap: Returning Genetic Results to Indigenous Communities in Latin America(Frontiers Media SA, 2023-01-01)In response to inequality in access to genomics research, efforts are underway to include underrepresented minorities, but explicit (and enforcing) guidelines are mostly targeted toward the Global North. In this work, we elaborate on the need to return scientific results to indigenous communities, reporting the actions we have taken in a recent genomic study with Mapuche communities in Chile. Our approach acknowledged the social dynamics perpetuating colonial hierarchies. We framed genetic results to empower indigenous knowledge and communities’ history and identities. A fundamental step in our strategy has been sharing the results with the communities before publishing the scientific paper, which allowed us to incorporate community perspectives. We faced the challenge of translating genetic concepts like admixture, emphasizing the distinction between identity and biology. To reach a broad and diverse audience, we disseminated the study results to single community members, cultural representatives, and high schools, highlighting the importance of the history of the region before the European contact. To facilitate results dissemination, we prepared didactic material and a report in Spanish written in non-specialized language, targeting a wider Latin American readership. This work illustrates the benefits of discussing scientific findings with indigenous communities, demonstrating that a collaborative and culturally sensitive approach fosters knowledge sharing and community empowerment and challenges power dynamics in genetic research. Bridging the gap between academia and indigenous communities promotes equity and inclusion in scientific endeavors. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, WITHDRAWN: Genome Report: Long read, high-coverage reference genomes of the Nymphalid butterflies <i>Catonephele acontius</i> and <i>Catonephele numilia</i> (Nymphalidae: Biblidinae)(Cold Spring Harbor Laboratory, 2026-01-22)Withdrawal Statement The authors have withdrawn this manuscript because in February 2026, the authors found that the Catonephele numilia specimen was misidentified and was in fact also Catonephele acontius . Thus, the data in the article describing the Catonephele numilia genome is invalid, as it in fact describes a second Catonephele acontius genome. This data invalidation has resulted in a loss of confidence in the results and conclusions reported in the article as far as they apply to Catonephele numilia . The data describing Catonephele acontius is not affected and remains valid. The authors are, therefore, retracting this article. All authors agree with the retraction. Therefore, the authors do not wish this work to be cited as reference for the project. If you have any questions, please contact the corresponding author. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Genomic epidemiology of SARS-CoV-2 in Peru from 2020 to 2024(Springer Nature, 2026)Background: Peru recorded one of the world’s highest COVID-19 mortality rates, with nearly 4.5 million reported cases and 220,000 deaths by March 2024. Understanding the emergence and spread of SARS-CoV-2 variants in this context is key to informing effective public health responses. This study describes the genomic diversity, transmission dynamics, and geographic spread of SARS-CoV-2 in Peru from 2020 to 2024. Methods: We analyzed nearly 50,000 high-quality public SARS-CoV-2 genome sequences collected nationwide between March 2020 and March 2024. Phylogeographic and mutational analyses were performed to identify variant lineages, trace their origins, and map viral movements within and beyond Peru. Results: We show that Peru’s epidemic waves were shaped by the emergence of locally evolved variants, including Lambda (C.37), Gamma (P.1.12), and Omicron (XBB.2.6 and DJ.1) sub-lineages. The city of Lima acted as the primary hub for inter-regional spread, accounting for 47.3% of inferred viral movements to other departments, notably Ancash, Cusco, and Piura. Peru was the source of various lineages that spread internationally, primarily to Chile, the USA, and Europe. Mutational analysis highlighted critical mutations in the spike protein, including L452Q and F490S in Lambda, associated with immune evasion and increased transmissibility. Conclusions: This work demonstrates the capacity of genomic surveillance in Peru to detect and track emerging SARS-CoV-2 variants, providing insights into regional and global transmission dynamics in a high-transmission, middle-income country setting. Sustained, cost-effective genomic monitoring, combined with strengthened bioinformatics and laboratory capacity, is essential for pandemic preparedness in resource-limited settings.
