Coix lacryma-jobi L. is one of the most economically and medicinally important corns. This study constructed a high-density genetic linkage map of C. lacryma-jobi based on a cross between the parents 'Qianyi No. 2' × 'Wenyi No. 2' and their F progeny through high-throughput sequencing and the construction of a specific-locus amplified fragment (SLAF) library. After pre-processing, 325.49 GB of raw data containing 1628 M reads were obtained. A total of 22,944 high-quality SLAFs were identified, among which 3952 SLAFs and 3646 polymorphic markers met the requirements for the construction of a genetic linkage map. The integrated map contained 3605 high-quality SLAFs, which were grouped into ten genetic linkage groups. The total length of the map was 1620.39 cM, with an average distance of 0.45 cM and an average of 360.5 markers per linkage group. This report presents the first high-density genetic map of C. lacryma-jobi. This map was constructed using an F population and SLAF-seq approach, which allows the development of a large number of polymorphic markers in a short period. These results provide a platform for precise gene/quantitative trait locus (QTL) mapping, map-based gene separation, and molecular breeding in C. lacryma-jobi. They also help identify a target gene for tracking, splitting quantitative traits, and estimating the phenotypic effects of each QTL for QTL mapping. They are of great significance for improving the efficiency of discovering and utilizing excellent gene resources of C. lacryma-jobi.

Antigen-induced clustering of cell surface receptors, including T cell receptors and Fc receptors, represents a widespread mechanism in cell signalling activation. However, most naturally occurring antigens, such as tumour-associated antigens, stimulate limited receptor clustering and on-target responses owing to insufficient density. Here we repurpose proximity labelling, a method used to biotinylate and identify spatially proximal proteins, to amplify designed probes as synthetic antigen clusters on the cell surface.

Serum uric acid (SUA) levels are linked to increased disease vulnerability and higher recurrence rates; however, the exact causal relationships are elusive. Despite the prevalent hyperuricemia in East Asian populations, comprehensive research on the intricate association between SUA levels and disease is lacking. To address this, a study utilizing a 2-sample Mendelian randomization (MR) approach was conducted in East Asian populations.

Pleiotropy, the phenomenon where a genetic region confers risk to multiple traits, is widely observed, even among seemingly unrelated traits. Knowledge of pleiotropy can improve understanding of biological mechanisms of diseases/traits, and can potentially guide identification of molecular targets or help predict side-effects in drug development. However, statistical approaches for identifying pleiotropy genome-wide are limited, particularly for two correlated traits or case-control traits with unknown sample overlap or for disease traits from family studies.

Familial hypertriglyceridemia (FHTG), a severe subtype of primary hypertriglyceridemia caused by mutations in and other related genes, is linked to life-threatening cardiovascular complications. Current therapies inadequately address the underlying genetic pathology. Here, we developed a novel exosome-based mRNA delivery platform to restore functional glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 () expression, providing a targeted therapeutic strategy for FHTG.
