CH02 peptide-stimulated periodontal ligament cells enhance periodontal defect repair in rats.

Objectives: Periodontal ligament cells (PDLCs) are considered ideal seed cells for periodontal tissue engineering and regeneration, and optimizing their efficacy is a pressing challenge. Although basic fibroblast growth factor (bFGF) has been extensively studied for promoting periodontal regeneration, its instability limits its application. This study introduces a smaller, less degradable peptide, CH02, to address this issue.

Research progress of polysaccharide drug delivery systems in the treatment of intestinal diseases: A review.

Intestinal diseases (IDs), as a type of complex immune-related diseases, have long faced challenges such as low drug delivery efficiency, insufficient targeting, and significant systemic toxic and side effects in their treatment strategies. Although oral administration is widely adopted due to its noninvasiveness and high patient compliance, the heterogeneity of the gastrointestinal environment severely limits the precise release and effective accumulation of drugs in the colon. Therefore, developing a new type of drug carrier system that can overcome physiological barriers and achieve colonic targeted delivery has become one of the core research directions in the field of ID therapy.

Uncovering the breeding contribution of transposable elements from landraces to improved varieties through pan-genome-wide analysis in rice.

Introduction: The rice improvement process, driven by modern breeding techniques, represents the second revolutionary advancement in rice agronomic traits, following domestication. Advances in pan-genomes and enhanced capacity for analyzing structural variations have increasingly highlighted their role in rice genetic improvement. Transposable element (TE) variants have been previously reported to influence rice genomic diversity during the domestication, but their contribution to the improvement from landraces to improved varieties remains unclear.

GWAS meta-analysis using a graph-based pan-genome enhanced gene mining efficiency for agronomic traits in rice.

Genome-wide association studies (GWASs) encounter limitations from population structure and sample size, restricting their efficacy. Though meta-analysis mitigates these issues, its application in rice research remains limited. Here, we report a large-scale meta-analysis of six independent GWAS experiments in rice to mine genes for key agronomic traits.

RBB1 negatively regulates rice disease resistance by modulating protein glycosylation.

Glycosylation, a prevalent post-translational modification in eukaryotic secreted and membrane-associated proteins, plays a pivotal role in diverse physiological and pathological processes. Although UDP-N-acetylglucosamine (UDP-GlcNAc) is essential for this modification, the specific glycosylation mechanisms during plant leaf senescence and defense responses remain poorly understood. In our research, we identified a novel rice mutant named rbb1 (resistance to blast and bacterial blight1), exhibiting broad-spectrum disease resistance.

Tonsils: the next frontier in the treatment of palmoplantar pustulosis.

Palmoplantar pustulosis (PPP) is a chronic relapsing inflammatory disease of unknown aetiology characterized by erythema, scaling, and aseptic pustules, which pose a significant clinical, psychological, and economic burden to patients. Studies have shown that the tonsils play a key role in the exacerbation and pathogenesis of certain diseases. This paper systematically summarizes the evidence supporting the close association between tonsils and PPP, and proposes mechanisms by which tonsils may contribute to the pathogenesis of PPP.

The pan-tandem repeat map highlights multiallelic variants underlying gene expression and agronomic traits in rice.

Tandem repeats (TRs) are genomic regions that tandemly change in repeat number, which are often multiallelic. Their characteristics and contributions to gene expression and quantitative traits in rice are largely unknown. Here, we survey rice TR variations based on 231 genome assemblies and the rice pan-genome graph.

A pan-TE map highlights transposable elements underlying domestication and agronomic traits in Asian rice.

Transposable elements (TEs) are ubiquitous genomic components and hard to study due to being highly repetitive. Here we assembled 232 chromosome-level genomes based on long-read sequencing data. Coupling the 232 genomes with 15 existing assemblies, we developed a pan-TE map comprising both cultivated and wild Asian rice.

Population-level exploration of alternative splicing and its unique role in controlling agronomic traits of rice.

Alternative splicing (AS) plays crucial roles in regulating various biological processes in plants. However, the genetic mechanisms underlying AS and its role in controlling important agronomic traits in rice (Oryza sativa) remain poorly understood. In this study, we explored AS in rice leaves and panicles using the rice minicore collection.

The novel potential therapeutic target PSMP/MSMP promotes acute kidney injury via CCR2.

Acute kidney injury (AKI) is a major worldwide health concern that currently lacks effective medical treatments. PSMP is a damage-induced chemotactic cytokine that acts as a ligand of CCR2 and has an unknown role in AKI. We have observed a significant increase in PSMP levels in the renal tissue, urine, and plasma of patients with AKI.

Recurrent Tuberous Sclerosis Complex/Mammalian Target of Rapamycin Mutations Define Primary Renal Hemangioblastoma as a Unique Entity Distinct From Its Central Nervous System Counterpart.

Renal hemangioblastoma (HB) is a rare subset of HBs arising outside of the central nervous system (CNS), with its molecular drivers remaining entirely unknown. There were no significant alterations detected in previous studies, including von Hippel-Lindau gene alterations, which are commonly associated with CNS-HB. This study aimed to determine the real molecular identity of renal HB and better understand its relationship with CNS-HB.
