From genotype to structure: MBL2 exon 1 and promoter variants associated with cytomegalovirus seropositivity in acute lymphoblastic leukemia from the Brazilian Amazon

This study demonstrates that specific MBL2 exon 1 and promoter variants are differentially associated with cytomegalovirus seropositivity in acute lymphoblastic leukemia patients and controls from the Brazilian Amazon, with structural modeling suggesting these genetic changes destabilize the MBL protein and impair its function.

Millions of eggs on volcanic summits reveal extraordinary deep-sea reproductive strategies

This study reveals that large, solitary deep-sea predators exhibit extraordinary reproductive strategies by concentrating millions of eggs into specific, geothermal-influenced seamount summits, where females actively select habitats across nested spatial scales for potentially decade-long incubation.

Atherosclerosis and Diabetic Foot Share a Common Molecular Signature of Cellular Senescence: A Multi-Omics and Machine Learning Study

This multi-omics and machine learning study reveals that atherosclerosis and diabetic foot ulcers share a common senescence-related molecular signature characterized by three core genes (CALCOCO1, CCND2, and FUCA1), which serve as robust diagnostic biomarkers and suggest metformin as a potential therapeutic agent for mitigating cellular senescence in these conditions.

Blood transcriptomic overlap between major depressive disorder and experimental sleep restriction in a reanalysis of public microarray data

This reanalysis of public microarray data found that apparent transcriptomic overlap between major depressive disorder and experimental sleep restriction is highly sensitive to analytical choices and failed to establish a statistically significant shared blood signature after false discovery rate control.

Androgen receptor expression is associated with a distinct low-proliferative phenotype in triple-negative breast cancer

This study demonstrates that androgen receptor expression in triple-negative breast cancer defines a distinct, low-proliferative molecular subtype characterized by specific genomic alterations, enhanced TGFβ signaling, and a unique immune microenvironment, although it does not independently predict patient survival.

Representation-dependent transportability of single-cell-derived myeloid- and fibroblast/stromal-associated transcriptional programs in bladder cancer

This study demonstrates that while single-cell-derived myeloid and fibroblast/stromal transcriptional programs maintain detectable within-lineage coherence and positive bulk correlations across external bladder cancer datasets, their transportability is representation-dependent and fails to preserve discrete cellular states, specific axes, or cellular interactions.

Effects of modelling choices on early invasive risk assessments: lessons from the psyllid vectors of Citrus Huanglongbing

This study demonstrates that expert-curated data, the inclusion of invaded-range records, and the use of invasion-specific evaluation metrics are critical for improving the accuracy and policy relevance of species distribution models used to assess the early invasion risk of citrus psyllid vectors.
