Summary: Exercise has significant effects on both the epigenome and proteome in human muscle. A 12-week high-intensity interval training intervention was conducted on 16 healthy moderately trained males, and muscle biopsies were collected at baseline and after 4, 8, and 12 weeks. The study found significant changes in proteins and DNA methylation levels, with some proteins consistently changed across individuals and the discovery of two novel exercise-related proteins. These findings contribute to a better understanding of the impact of exercise on the human body.

Summary: Living organisms adapt to environmental changes through genomic and epigenomic responses, which also influence their sensitivity to environmental chemicals. This study explored the intraspecific variation in sensitivity to the biocide CMIT/MIT in Daphnia populations and found that the variation within a species could be greater than the variation between different species. The study also identified strain-specific epigenetic and proteomic responses to CMIT/MIT, highlighting the role of genetic and epigenetic factors in phenotypic differences and chemical sensitivity.

Summary: Epigenetics refers to events independent of nucleotide sequence and heritable changes, including DNA methylation and histone modification, which contribute to phenotypic features of cells. Both genetics and epigenetics play roles in determining the outcomes of regulatory gene expression systems, with the flexibility of epigenetic effects and stability of genetic coding leading to complexity in gene regulation.

Summary: Epigenome-wide association studies (EWAS) can identify genes related to clinical endpoints, potentially leading to new diagnostic biomarkers and therapy options. Combining EWAS with deep molecular phenotyping allows further exploration of disease pathways. Methylation of certain genes is associated with specific diseases or physiological challenges, offering possibilities for early diagnosis.

Summary: This study aimed to investigate the epigenetic mechanism of visceral hypersensitivity in IBS-D by integrating the relationship between differentially expressed miRNAs, mRNAs, and proteins. The expressions of several miRNAs were found to be significantly different in IBS-D patients, and they were found to regulate various molecules and signaling pathways.

Summary: This study compared the proteome and global DNA methylation patterns of orbital fibroblasts isolated from active GO, inactive GO, and healthy controls. The results showed that orbital fibroblasts from active GO are involved in inflammation, cellular proliferation, hyaluronan synthesis, and adipogenesis, while fibroblasts from inactive GO are more focused on extracellular matrix remodeling. The findings suggest a potential therapeutic target in the effector function of orbital fibroblasts in Graves' ophthalmopathy.

Summary: Sjogren's syndrome is a common autoimmune disease characterized by dry mouth and eyes, and can involve multiple systems. Previous research has focused on the role of B cells and T cells in the pathogenesis and progression of Sjogren's syndrome. However, recent studies have identified monocytes as a third player connecting innate and adaptive immunity in this disease.

Summary: This study analyzed the methylation profiles of individuals with chromatinopathies and identified unique genome-wide DNA methylation profiles, which were matched and confirmed with known episignatures. Additionally, uncertain variants were reclassified as likely pathogenic, and specific chromatinopathy disorders were identified in some sequencing negative cases. Therefore, DNA methylation analysis plays an important role in diagnosing chromatinopathies.

Summary: In this study, the chromatin proteomes of various mouse organs were analyzed using quantitative proteomics. The results showed distinct and organ-specific temporal protein expression profiles and regulation at the post-translational level. The spleen exhibited a static chromatin proteome, reflecting its important role in physiological defense and immunity. These findings support the hypothesis that chromatin-associated proteins are involved in distinct and specific physiological functions in ageing organs.

Summary: Capsule retention is a common complication of capsule endoscopy, but the introduction of the patency capsule and better patient selection have led to lower rates of retention. In a retrospective analysis of 1,127 patients referred for capsule endoscopy, 166 patients underwent patency assessment and no capsule retention was observed in those who passed the assessment. The patency capsule remains an imperfect but useful tool in evaluating the functional patency of the GI tract before capsule endoscopy.

Summary: Fiber optic bundles are commonly used in narrow-diameter instruments to acquire images from confined spaces. However, the current imaging method has limitations in spatial resolution due to the information restriction in fiber cores and the loss of information in the cladding region. In this study, computational imaging (CI) combined with spectral coding was proposed to overcome these limitations and improve spatial resolution in fiber bundle imaging.

Summary: Genetic knockout of PepT1 protein provides resistance to acute colitis and colitis-associated cancer in mouse models. The altered fecal metabolites, particularly tuberonic acid (TA), in PepT1 KO mice play a crucial role in anti-inflammatory effects and epithelial cell healing processes. This study sheds light on the potential mechanisms associated with the protective effects of PepT1 KO.

Summary: Oral mRNA delivery is a promising approach for treating inflammatory bowel disease. Researchers developed a new lipid nanoparticle (nLNP) to encapsulate IL-22 mRNA, a known anti-inflammatory substance. Oral delivery of IL-22/nLNPs increased IL-22 expression in the colonic mucosa of mice and accelerated the healing process of colitis.

Summary: Modulating gut microbiota composition is an effective approach for treating chronic diseases, but current methods carry the risk of transmitting multi-drug-resistant organisms. In this study, an organism-free strategy was developed to modulate gut microbiota ex vivo and transfer microbiota-secreted metabolites back to the host, and it was found to effectively prevent chronic ulcerative colitis.

Summary: The researchers loaded the anti-cancer drug candidate M13 into colon-targeting ginger-derived nanoliposomes (NL) and investigated the enhanced anticancer effects of orally administered M13-NL on CAC in mouse models. M13 showed favorable physiochemical properties and no apparent immunotoxicity or mutagenic potential. The use of NL for drug delivery significantly improved the safety and efficacy of M13, and oral administration of M13-NL demonstrated excellent therapeutic effects in CAC mouse models.

Summary: Our study demonstrated that ginger-derived nanoparticles could effectively target the colon, reduce colitis, and alleviate colitis-associated colon cancer. We successfully constructed ginger lipid-derived nanoparticles as a carrier to deliver drug candidates to the colon, providing a detailed protocol for this process. Using atomic force microscopy, we visualized the nanostructure of the drug-loaded nanoparticles.
