Therefore, in this study, we aimed to elucidate the biological process and identify the potential biomarker for LNM in CRC. In total, 12 significant DEGs between the patients with and without LNM were identified, consisting of significantly upregulated S100A8 gene, a proinflammatory gene. The GSEA revealed that gene sets involving “MULTI CANCER INVASIVENESS” in terms related to epithelial-mesenchymal transition was significantly upregulated in the patients with LNM. Integrated functional analysis of DNA methylation with transcriptome profile shows that significantly hypomethylated promoters of the genes are enriched for LNM. The phylum Proteobacteria, unassigned (p_PU) presented significantly higher proportions in cancer tissues from the adjacent normal tissues. Notably, when compared to the patients without LNM, the gut microbiota of those with LNM appears to exhibit a significantly lower abundance of the p_PU, indicating its potential as promising biomarker for LNM in CRC. We explained the mechanism of tumor spreading using multi-omics analysis and identified the relevant metagenomic biomarker to predict the LNM in CRC by the recognition of host-microbial interaction, thereby can make the cancer surveillance of the patients more individualized and convincing.

Mounting evidence indicates that dietary restriction counters age-dependent effects and increases and enhances health and longevity in whole organisms, while less is known of aging and nutrition on individual organs of an organism. Here, we studied the responsible organ for nutrient uptake, the intestinal tube, along the lifetime of an organism. A longitudinal study was conducted on the morphology and gene expression of the gut tubes of the very short-lived aging model system African turquois killifish (Nothobranchius furzeri). The aim was to investigate the age and nutrition-related effects on gut tissue preservation at stages corresponding to human newborn, adolescence, adult and old age. The intestinal mucosa is characterized by folds and intervening interfold regions, in which the intestinal stem cells were localized. The stem cells were found to occur in clusters and that the cycling time of stem cells extends at old age. Concomitantly, we found a reduction in intestinal length and volume with age. Age-dependent gene expression revealed significant alterations in the expression of peripheral circadian clock genes and marker genes of stem cell niches. Notably, the majority of these genes retained their adult gene expression levels at old age after dietary restriction. Thus, our results demonstrate that the decline of structural intestinal tissue homeostasis is caused by a declining activity of stem cells, and that these effects are counteracted by dietary restriction

It is difficult to diagnose and treat, which seriously endanger people’s the physical and mental health. Actinic keratosis (AK) induced by ultraviolet radiation is the precancerous lesion of cSCC. The mechanism of occurrence and development of cSCC is still unclear, and the research on epigenetics is even less. In this project, we intend to study the mechanism of cSCC, especially the transformation from normal skin to AK, cSCC and the metastasis in late stage of cSCC, using multi-omics sequencing technology with experimental methods. Through the integrated analysis of multi-omics information such as DNA methylation, RNA methylation, chromatin accessibility and transcriptome, we obtained the epigenetic map of different stages of cSCC and identified the potential key epigenetic driving factors for cSCC. This project provided an important scientific basis for the clinical treatment and drug development of cSCC, as well as method reference for the study of other cancers.

  • 📝 描述:Contributors : Jeff X Ji ; Brian L Giles ; Surjyadipta Bhattacharjee ; Marie-Audrey I Kautzmann ; Alisdair P Masson ; Sonia Do Carmo ; Claudio Cuello ; Nicolas G BazanSeries Type : Expression profiling by high throughput sequencing ; Genome binding/occupancy profiling by high throughput sequencing ; OtherOrganism : Rattus norvegicusAlzheimer’s disease (AD) is the leading cause of dementia in elderly individuals worldwide; however, all the mechanisms leading to its onset and progression are not fully understood. Here, we report single-cell multiome and spatial transcriptomics analysis of the brain in a transgenic rat model of human-like tauopathy. In this advanced transgenic model, we have identified new markers of a tau-driven AD pathology and provided single-cell evidence for previously known genes implicated in AD. Our findings reveal how tau pathological hyperphosphorylation and aging alter ligand-receptor communication, transcription factor regulatory networks, and specific cellular networks. Notably, we found intriguing changes in cell communication involving glutamatergic transmission and netrin signaling as a consequence of the tauopathy. Overall, this study reinforces the concept of synaptic dysfunction as a hallmark of AD and highlights potential targets for future mechanistic investigations or novel therapeutic strategies.

10.GSE262964 抗坏血酸通过结合 Myh9 蛋白和富集肠道菌群 Akkermansia muciniphila 来增加 CD8+ T 细胞,改善中年小鼠的认知水平 [scRNA-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:scRNA、gut、regex:gut(-?microbiome)?
  • 📝 描述:Contributor : Hailiang LiuSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusImmunosenescence hastens the process of systemic aging and impacts cognitive function, with antioxidants potentially ameliorating these consequences. This research systematically assessed the impact of ascorbic acid (vitamin C) on immunosenescence and cognitive function in middle-aged and elderly mice. The findings demonstrated a notable rise in peripheral blood lymphocytes, a decline in myeloid immune cells, and enhanced cognitive performance. In vitro studies indicated that ascorbic acid facilitated the differentiation of mouse hematopoietic stem cells (HSCs) and spleen monocytes into CD8+ T cells, with its efficacy primarily mediated by its interaction with the binding protein Myh9. Additionally, a positive correlation was observed between CD8+ T cells and cognitive function. Furthermore, a distinction exists between the efficacy of oral and intravenous administration of ascorbic acid in enhancing cognitive function, potentially attributable to the modulation of the gut microbiome Akkermansia muciniphila. Intravenous delivery notably enhances A. muciniphila abundance and significantly enhances cognitive performance in middle-aged and elderly mice, whereas oral ascorbic acid supplementation increases CD8+ T cell count and cognitive function in this demographic only when co-administered with A. muciniphila. This study demonstrated that the administration of ascorbic acid can mitigate immunosenescence and, in conjunction with A. muciniphila, improve cognitive function in mice. These findings offer a mechanistic rationale for utilizing immunomodulatory interventions to enhance cognitive function, underscoring the significance of selecting the optimal route of administration for achieving the intended effects.
