Article Abstract
The number of people with HIV (PWH) in Africa is rising due to population growth and antiretroviral therapy (ART) availability, with diffuse large B-cell lymphoma (DLBCL) a major cause of mortality. HIV and ART alter DLBCL tumor biology, but few studies of DLBCL include PWH or African patients, limiting translation of emerging treatment strategies. Here, we performed whole exome sequencing of 48 tumors (40 HIV-positive [HIV+]) with paired germline of DLBCL patients from Malawi and South Africa. HIV + DLBCL tumors had distinct mutations depending on ART exposure, and there were several recurrent deleterious variants, with ANKRD11 mutations being prognostic. One tumor from each cohort had high tumor mutational burden and microsatellite-instability with PMS2 and ARID1A mutation. These findings suggest shared genomic characteristics among HIV + DLBCL in Africa, offering opportunities for tailored biomarkers and therapeutic targets for this underserved population.

Background: Laboratory animal veterinarians play a crucial role as a bridge between the ethical use of laboratory animals and the advancement of scientific and medical knowledge in biomedical research. They alleviate pain and reduce distress through veterinary care of laboratory animals. Additionally, they enhance animal welfare by creating environments that mimic natural habitats through environmental enrichment and social associations.

Background: Recent advances in high-throughput sequencing technologies have enabled the collection and sharing of a massive amount of omics data, along with its associated metadata-descriptive information that contextualizes the data, including phenotypic traits and experimental design. Enhancing metadata availability is critical to ensure data reusability and reproducibility and to facilitate novel biomedical discoveries through effective data reuse. Yet, incomplete metadata accompanying public omics data may hinder reproducibility and reusability and limit secondary analyses.

Parasites can induce gene expression changes in their hosts, either benefiting the parasite or the host. In particular, trematodes are not only one of the most ubiquitous groups of aquatic parasites, they also have huge impacts on individual hosts with significant ecological and economic repercussions. The trematode Bucephalus minimus infects Cerastoderma edule (the edible cockle), a socioeconomically and ecologically important bivalve, as its first intermediate host.

Single-cell studies on breast tissue have contributed to a change in our understanding of breast epithelial diversity that has, in turn, precipitated a lack of consensus on breast cell types. The confusion surrounding this issue highlights a possible challenge for advancing breast atlas efforts. In this perspective, we present our consensus on the identities, properties, and naming conventions for breast epithelial cell types and propose goals for future atlas endeavors.
