This study focuses on porcine epidemic diarrhea virus (PEDV), a highly virulent and rapidly evolving coronavirus threatening global swine production. We established a novel genotype system of PEDV targeting site-specific polymorphisms in the spike (S) protein. The system demonstrates that frequent recombination events at both termini of the S gene serve as a critical mechanism driving genotypic diversity in PEDV. Together with adaptive evolution, these processes collectively shape the evolutionary dynamics of global PEDV strains. The research provides critical theoretical foundations for understanding PEDV genome evolution patterns and developing prevention and control measures.

Akkermansia muciniphila (A. muciniphila), regarded as a promising candidate for next-generation probiotic applications, predominantly inhabits the intestinal mucus layer, where it plays a crucial role in maintaining gut barrier integrity and modulating immune responses. Recently, the bacterium has been recognized for its ambivalent influence on cancer, impacting both tumor progression and therapeutic interventions. Research indicates that A. muciniphila might possess both tumorigenic and anticancer capabilities, influenced by factors such as the composition of the gut microbiota, dietary modifications, and immune modulation. There is a compelling need for further studies to uncover the precise mechanisms and optimal use of A. muciniphila in oncology and beyond.

The skin microbiome plays a crucial role in skin health, influencing barrier integrity, immune responses, and disease susceptibility. Various interventions can reshape the microbiome, broadly categorized into targeted and untargeted approaches. Targeted strategies, such as phage therapy, engineered bacteria, and phage lysins, selectively modulate specific microbial populations, restoring balance and mitigating pathogenic influences. Untargeted interventions, including probiotics, prebiotics, skin microbiome transplantation, antibiotics, and lifestyle modifications, aim to enhance overall microbial diversity and stability. These strategies hold promise for innovative dermatological therapies, paving the way for personalized microbiome-based treatments. However, challenges remain in standardization, safety, and long-term ecological impact, necessitating further research for effective clinical translation.

We systematically compared and assessed the commonly used methods for studying live soil microbes, including alkaline buffer washing, propidium monoazide (PMA) treatment, DNase pre-digestion, and rRNA-based analysis, based on soils collected across the western region of China. The results showed that the elimination of extracellular DNA largely affected the analysis of soil prokaryotic abundance, diversity, community profiles, and co-occurrence patterns, but the effects varied considerably across different methods. In contrast, extracellular DNA removal exerted negligible effects on the determination of community assembly mechanisms. We also observed substantial variations in the performance of different methods in characterizing soil live prokaryotic communities, and DNase pre-digestion was recommended for studying soil live prokaryotic communities.

In this study, we explored the therapeutic effects of Parabacteroides goldsteinii (P. goldsteinii) on colitis and its underlying mechanisms. Our results indicate a significant reduction of P. goldsteinii in the stools of inflammatory bowel disease patients. We demonstrate the therapeutic potential of P. goldsteinii in mitigating dextran sulfate sodium-induced colitis and restraining tumorigenesis in the azoxymethane (AOM)/DSS mouse model under a fiber-free diet. Metabolomic profiling further revealed an enrichment of fecal secondary bile acids in response to P. goldsteinii. By employing bile salt hydrolase inhibitors and Takeda G-protein-coupled receptor 5 (Tgr5) knockout mice, we established a connection between the anti-inflammatory effect of P. goldsteinii and fecal bile acids. Furthermore, our findings highlight the modulatory role of diet in enhancing P. goldsteinii's therapeutic potential, underlining the importance of diet in future probiotic research.

These systems demonstrate potential in HCC treatment by facilitating the transportation of diverse therapeutic drugs. This comprehensive review aims to delve into the application of nanoparticle drug delivery systems in the management of liver tumors, with particular emphasis on formulation, targeted strategies specific to liver tumors, and various methods of drug release. By offering insights into the utilization of nanoparticle drug delivery systems in the realm of liver tumor treatment, this review endeavors to assist readers in exploring their vast potential.

Antibiotic pretreatment is routine for chronic dacryocystitis (DC) patients. Herein, the longitudinal effects of antibiotic pretreatment before dacryocystorhinostomy for DC patients were evaluated. Conjunctival and nasal swabs were collected longitudinally from 33 DC patients with and without antibiotic pretreatment, both before dacryocystorhinostomy and at 1, 2, and 4 weeks postdacryocystorhinostomy. Additionally, conjunctival sac swabs were collected from 46 healthy volunteers and 14 other ocular diseases patients. Comparisons focused on ocular/nasal microbiota and recovery outcomes. Compared to healthy participants, DC patients without antibiotic pretreatment exhibited greater ocular microbiota diversity before dacryocystorhinostomy. Although clinical recovery rates were comparable, our results suggest that, after antibiotic pretreatment, the ocular microbiota richness and diversity, and the composition alteration tendency, significantly changed 4 weeks after surgery. This implies that the ocular microbiota was more disturbed in patients who underwent antibiotic pretreatment compared to those without such treatment. Furthermore, two types of ocular microbiota and three types of nasal microbiota were identified in ocular diseases. This study provides comprehensive data on the ocular and nasal microbiota in DC patients with and without antibiotic pretreatment, along with other ocular diseases. This finding suggested that antibiotic pretreatment may not be necessary before dacryocystorhinostomy for DC patients, especially for nonsevere cases.

Fine-needle aspiration cytology and imaging examinations are commonly used diagnostic tools for papillary thyroid carcinoma (PTC). However, these methods have limitations. Inflammatory proteins have the potential to serve as diagnostic and prognostic markers, as well as treatment targets. The expression profile and diagnosis effect of inflammatory proteins in PTC are not well understood. Here, 18 healthy volunteers (as healthy control), 12 patients with nodular goiter, and 34 patients with PTC were collected to analyze serum inflammatory proteins by proximity extension assay. Receiver operating characteristic curve analysis was used to evaluate the diagnostic potential of differential expression of proteins via the area under the curve (AUC) analysis. A total of 36 differentially expressed inflammatory proteins were found among PTC, nodular goiter, and healthy control. The combination diagnosis derived from the logistic regression analysis exhibited promising diagnostic capabilities in distinguishing nodular goiter from healthy control (AUC = 0.88), distinguishing PTC from healthy control (AUC = 0.89), and distinguishing PTC from nodular goiter (AUC = 0.87). Whereas the combination diagnosis derived from the least absolute shrinkage and selection operator (LASSO) exhibited promising diagnostic capabilities in distinguishing nodular goiter from healthy control (AUC = 0.92), distinguishing PTC from healthy control (AUC = 0.93), and distinguishing PTC from nodular goiter (AUC = 0.93). Overall, this study offers potential biomarkers for distinguishing between PTC and nodular goiter in clinical practice. The combination derived from the LASSO algorithm outperforms logistic regression.

Glycosylation plays a pivotal role in the physiological and pathological processes of male reproduction. It impacts thousands of proteins and is actively ongoing through all stages of reproduction, including spermatogenesis, maturation, capacitation, and fertilization. However, our grasp on glycosylation within male reproductive processes remains limited, largely due to the technical hurdles. Recent advancements have seen the mapping of the glycoproteome of human semen, utilizing cutting-edge glycoproteomic technologies. This breakthrough lays the groundwork for in-depth research into the influence of glycosylation on male reproductive system and related disorders. Nevertheless, the field faces numerous challenges that necessitate further advancements in glycoproteomic methodologies. In this analysis, we evaluated the potential applications of advanced glycoproteomic techniques in the study of male reproduction and summarized the detailed profiling of the human semen glycome and glycoproteome. Our current understanding of glycosylation's role within the male reproductive system alongside recent progress in glycoproteomics may equip biologists with a comprehensive insight. Furthermore, this analysis brought together findings on abnormal glycosylation and its link to male reproductive disorders in the view of glycomics and glycoproteomics. It can facilitate the clinical application of glyco-related biomarkers and targets in the treatment of infertility.

The 45 diploid cotton species identified worldwide exhibit remarkable morphological diversity. Modern cotton breeding is limited by incomplete understanding of the genetic variation in these species, suggesting a need for pan-genomic comprehensive analyses. In this study, a high-quality super pan-genome was built using 22 representative diploid cottons species and their adaptive evolution was investigated. The genomes of the twenty-two species yielded an average of 923,706 transposable elements (TEs) per assembly, with TE proportions ranging from 62.29% to 88.92%. The inferring ancestor genome structure (IAGS) showed that the D5 genome was closer to the ancestor, and the K2 genome accumulated more fissions and fusions. A gene-based super pan-genome identified 67,807 genes, including 22,384 core, 34,093 variable, and 11,330 specific genes. The structural variations (SVs) were unevenly distributed on the chromosomes, and 321 hotspot regions were detected, containing 90 genes associated with fiber initiation and/or elongation. During the eastward diffusion of diploid cotton, the genome size and structure experienced significant changes. We investigated the foliar nectary in 17 diploid cotton species, and identified a 444-bp deletion in the promoter sequence of GoNe that explained the lack of foliar nectary in G. gossypiodes (D6) and G. schwendimanii (D11). This pan-genome construction and comprehensive analysis for diploid cotton provided insight into dynamic genomic variation during diploid cotton expansion and can facilitate effective modern cotton breeding.

Bacteria often exist and function as a community, known as the bacterial microbiota, which consists of vast numbers of bacteria belonging to many bacterial species (taxa). Characterizing the bacterial microbiota needs high-throughput approaches that enable the identification and quantification of many bacterial cells, and such approaches have been under development for more than 30 years. In this review, we describe the history of high-throughput technologies based on 16S ribosomal RNA (rRNA) gene-amplicon sequencing for the characterization of bacterial microbiotas. Then, we summarize the features and applications of current 16S rRNA gene-amplicon sequencing approaches, including a recent achievement that enables the identification of individual cells with single-base accuracy for 16S rRNA genes and the quantification of many identified cells. Furthermore, we present the prospects for further technical development, including the combined use of high-throughput methods and other informative analyses, such as whole-genome sequencing in the common unit of the cell, which enables bacterial microbiota characterization based on both the number of cells and their functions.

Dysregulation of the gut microbiota often leads to immune-related disorders, indigestion, or diarrhea. Here, Jiaxing Black (JXB) pig, a local Chinese pig breed known for its great tolerance and digestibility of nutrients, was employed for a metagenomic and transcriptomic integrative analysis to reveal the gut microbiota-genes and gut microbiota-pathway interactions. A total of 452 differentially expressed genes, and 174 phyla were found between the JXB and the Duroc × Landrace × Yorkshire (DLY) pigs. Detailed analysis revealed that the differences in colon gene expression signatures between the JXB and DLY are mainly enriched in metabolic and inflammatory responses, with Lactobacillus and Lachnospiraceae enriched in DLY and JXB, respectively. Notably, Pacebacteria, Streptophyta, and Aerophobetes were found to participate in the PI3K-Akt mediated immune response in both pig breeds; however, they only accelerated the metabolism in the intestines of JXB pigs. Moreover, the host could regulate microbe metabolism and immune response by Ig-like domain-containing protein and ITIH2, PAEP, and TDRD9, respectively. Taken together, our results revealed both common and breed-specific regulations of host genes by gut microbiota in two pig breeds.
