Here, we describe the Herbivore Transcriptome Integrated Resource Database (HTIRDB, https://yanglab.hzau.edu.cn/HTIRDB#/). The HTIRDB comprises the self-generated transcriptomic data from 100 to 105 tissues from two female domestic herbivores from six species (cattle, donkey, goat, horse, rabbit, and sika deer) and two breeds of sheep, and an extra 28,710 related published datasets. The HTIRDB user-friendly interface provides tools and functionalities that facilitate the exploration of gene expression between tissues and species. The tools for comparative transcriptomics can be used to identify housekeeping genes, tissue-specific genes, species-specific genes, and species-conserved genes. To date, the HTIRDB is the most extensive transcriptome data resource for domestic herbivores that is freely available.
The treeio and ggtree packages provide robust tools for the comprehensive parsing and visualization of phylogenetic placement data. These tools enable detailed analyses, including placement filtration and uncertainty assessment, thereby facilitating deeper insights into evolutionary relationships within metagenomic datasets.
In this study, we comprehensively profiled plasma oxylipin alterations in patients with ST-segment elevation myocardial infarction (STEMI) with and without recurrent major adverse cardiovascular events (MACE) in a prospective cohort (n = 645) with 2 years of follow-up. Using a multivariate random forest algorithm, we identified a panel of 14 oxylipin markers that showed powerful performance in predicting recurrent MACE. The predictive performance of the oxylipin marker panel was confirmed in an independent external validation cohort (n = 401). Using functional metabolomics strategies, we found that six anti-inflammatory/pro-resolving oxylipin combinations had synergistic and cardioprotective effects on a murine model of myocardial ischemia‒reperfusion injury. Mechanistically, we demonstrated that inflammatory/pro-resolving oxylipins could reinstate the synthesis of ceramides and lysophosphatidylcholines and ameliorate inflammatory responses. Collectively, our studies highlight the great potential of bioactive oxylipins in prognostic prediction and therapeutics after STEMI.
Accumulating evidence indicates that the gut microbiota is intricately involved in the initiation and progression of human diseases, forming a multidirectional regulatory axis centered on intestinal microbiota. This article illustrates the challenges in exploring the role of the gut microbiota in inflammatory digestive diseases, such as metabolic dysfunction-associated steatotic liver disease (MASLD) and inflammatory bowel disease (IBD), and summarizes the existing microbiome-focused treatment strategies (probiotics, prebiotics, symbiotics, fecal microbiota transplantation, and bacteriophages therapy), emerging technologies (gut microbiome-on-a-chip and artificial intelligence), as well as possible future research directions. Taken together, these therapeutic strategies and technologies present both opportunities and challenges, which require researchers and clinicians to test the rationality and feasibility of various therapeutic modalities in continuous practice.
This study explores the role of IgA-coated bacteria in improving feed efficiency in chickens, offering a novel perspective for probiotic screening. Chickens with high feed efficiency were found to have a greater abundance of Gram-positive bacteria, while low feed efficiency chickens exhibited higher levels of Gram-negative bacteria and potential pathogens. Through fecal microbiota transplantation (FMT) and integrating analysis of cecal and IgA-coated microbiota, we precisely identified Blautia as a key genus linked to improved feed efficiency. Further validation demonstrated that Blautia coccoides, a representative species of this genus, enhances feed efficiency and activates B cells to produce Immunoglobulin A (IgA), both in vivo and in vitro. Our findings provide new insights into the potential of IgA-coated bacteria as functional probiotics, offering a promising strategy for enhancing feed efficiency in animal production.
Given the key role of energy grasses in biomass energy, electricity, biofuels, and carbon sequestration, the Energy Grass Omics Database (EGDB) integrates germplasm data with genomics, transcriptomics, epigenomics, and phenomics data to support functional genomic research on diverse energy grass species. EGDB also currently supplies the largest epigenetic data set of energy grasses: a high-resolution chromatin modification, chromatin accessibility, and gene expression landscape of pearl millet to provide insights into regulatory traits essential for sustainable energy production.
Fastp is a widely adopted tool for FASTQ data preprocessing and quality control. It is ultrafast and versatile and can perform adapter removal, global or quality trimming, read filtering, unique molecular identifier processing, base correction, and many other actions within a single pass of data scanning. Fastp has been reconstructed and upgraded with some new features. Compared to fastp 0.20.0, the new fastp 0.23.2 is even 80% faster.
