The mouse genomic sequence of the region containing the gene Rhced, the orthologue to the human gene RH30, was determined to elucidate the structure of Rhced and its flanking regions and to compare these with the corresponding human genomic region. Two genes, Smp1 and AK003528 (an orthologue of FLJ10747), flank Rhced. Neither sequences homologous to the characteristic nucleotide elements flanking the RHD gene in humans (rhesus boxes) nor an additional Rh gene were found within the mouse region sequenced. This result and that of a previous report demonstrate that this chromosomal region of the mouse comprises five genes (FLJ10747-RHCE-SMP1-NPD014-P29) that exhibit syntenic homology with the corresponding human region, which suggests that the RHD gene and rhesus boxes were inserted later. Evaluations of tissue distribution and subcellular localization of these genes indicate that the SMP1 orthologue has a ubiquitous tissue distribution and cytoplasmic localization, whereas AK003528 is expressed slightly higher in testis with a strong subcellular localization in the nucleus. Despite the steady improvements in the draft sequence of the human genome, this study demonstrates the continuing benefits of comparative genetic analyses in increasing our understanding of human genomic structure.

High concentrations of neutrophil degranulation products in the plasma and thrombi are poor prognostic indicators in patients with acute ischemic stroke (AIS). This study aimed to identify candidate effectors capable of mediating neutrophil degranulation post-AIS, and to reveal their underlying epigenetic mechanisms. Microarrays and ChIP-seq were applied to analyze the neutrophils of patients with AIS.

Aerobic exercise (AE) has been shown to offer significant benefits for Alzheimer's disease (AD), potentially influencing the gut microbiota. However, the impact of changes in intestinal flora in early Alzheimer's disease induced by aerobic exercise on metabolic pathways and metabolites is not well understood. In this study, 3-month-old APP/PS1 and C57BL/6 mice were divided into two groups each: a control group (ADC for APP/PS1 and WTC for C57BL/6) and an aerobic exercise group (ADE for APP/PS1 and WTE for C57BL/6).

Assay for Transposase-Accessible Chromatin with sequencing (ATAC-seq) is a powerful, high-throughput technique for assessing chromatin accessibility and understanding epigenomic regulation. Neutrophils, as a crucial leukocyte type in immune responses, undergo substantial chromatin architectural changes during differentiation and activation, which significantly impact the gene expression necessary for their functions. ATAC-seq has been instrumental in uncovering key transcription factors in neutrophil maturation, revealing pathogen-specific epigenomic signatures, and identifying therapeutic targets for autoimmune diseases.

Skeletal muscle function gradually declines with aging, presenting substantial health and societal challenges. Comparative analysis of how aging affects fast- and slow-twitch muscles remains lacking. We utilized 20-month-old mice to reveal the aging effects on muscle structure and fiber composition, followed by bulk RNA sequencing for fast- and slow-twitch muscles and integration with human single-cell RNA sequencing dataset providing a comparative analysis across species.

Abdominal aortic aneurysm represents a critical pathology of the aorta that currently lacks effective pharmacological interventions. TNF receptor-associated factor 6 (TRAF6) has been established to be involved in cardiovascular diseases such as atherosclerosis, hypertension, and heart failure. However, its role in abdominal aortic aneurysm (AAA) remains unclear.
