A robust transfer learning approach for high-dimensional linear regression to support integration of multi-source gene expression data.

Transfer learning aims to integrate useful information from multi-source datasets to improve the learning performance of target data. This can be effectively applied in genomics when we learn the gene associations in a target tissue, and data from other tissues can be integrated. However, heavy-tail distribution and outliers are common in genomics data, which poses challenges to the effectiveness of current transfer learning approaches.

IL-22-mediated microRNA-124-3p/GRB2 axis regulates hyperproliferation and inflammatory response of keratinocytes in psoriasis.

Psoriasis is an inflammatory dermatosis that features overproliferation and inflammatory reaction of keratinocytes. A study reported that IL-22 is involved in the pathogenesis of psoriasis by mediating miR-124 to regulate the expression of fibroblast growth factor receptor 2 in keratinocytes. A microRNA may target multiple target genes.

Single-Cell Multi-omics Assessment of Spinal Cord Injury Blocking via Cerium-doped Upconversion Antioxidant Nanoenzymes.

Spinal cord injury (SCI) impairs the central nervous system and induces the myelin-sheath-deterioration because of reactive oxygen species (ROS), further hindering the recovery of function. Herein, the simultaneously emergency treatment and dynamic luminescence severity assessment (SETLSA) strategy is designed for SCI based on cerium (Ce)-doped upconversion antioxidant nanoenzymes (Ce@UCNP-BCH). Ce@UCNP-BCH can not only efficiently eliminate the SCI localized ROS, but dynamically monitor the oxidative state in the SCI repair process using a ratiometric luminescence signal.

This includes setting the ethical boundaries for medical artificial intelligence and safeguarding both patient rights and data integrity.

Bidirectional histone monoaminylation dynamics regulate neural rhythmicity.

Histone H3 monoaminylations at Gln5 represent an important family of epigenetic marks in brain that have critical roles in permissive gene expression. We previously demonstrated that serotonylation and dopaminylation of Gln5 of histone H3 (H3Q5ser and H3Q5dop, respectively) are catalysed by transglutaminase 2 (TG2), and alter both local and global chromatin states. Here we found that TG2 additionally functions as an eraser and exchanger of H3 monoaminylations, including H3Q5 histaminylation (H3Q5his), which displays diurnally rhythmic expression in brain and contributes to circadian gene expression and behaviour.

Inhibition of Abdominal Aortic Aneurysm Progression Through the CXCL12/CXCR4 Axis via MiR206-3p Sponge.

Notably, the C-X-C Motif Chemokine Ligand 12/C-X-C Chemokine Receptor Type 4 (CXCL12/CXCR4) signalling pathway's activation is markedly increased in a mouse model of abdominal aortic aneurysms (AAA). Nonetheless, the precise contribution of this pathway to AAA development remains to be elucidated. The AAA mouse model was induced by local incubation with elastase and oral administration of β-aminopropionitrile.

The effects of the Wnt/β-catenin signaling pathway on the in vitro differentiation of rat BMSCs into leydig cells.

Late-onset hypogonadism (LOH) refers to sexual and non-sexual symptoms in men caused by age-related decreases in circulating testosterone. Leydig cells (LCs) transplantation is considered to be one of a viable approach for LOH therapy, but the limited source of LCs limits the application of this approach. The aim of this study was to induce the directed differentiation of rat bone marrow mesenchymal stem cells (BMSCs) into LCs in vitro, and explore the potential involvement of Wnt/β-catenin signaling pathway in the differentiation process.

Regulation of cGAS-STING signalling and its diversity of cellular outcomes.

The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signalling pathway, which recognizes both pathogen DNA and host-derived DNA, has emerged as a crucial component of the innate immune system, having important roles in antimicrobial defence, inflammatory disease, ageing, autoimmunity and cancer. Recent work suggests that the regulation of cGAS-STING signalling is complex and sophisticated. In this Review, we describe recent insights from structural studies that have helped to elucidate the molecular mechanisms of the cGAS-STING signalling cascade and we discuss how the cGAS-STING pathway is regulated by both activating and inhibitory factors.
