Transcriptome analysis of cardiac tissues from mice subjected to SD model with oxygen therapy

ABSTRACT: Adequate sleep is essential for relieving stress and rejuvenating the mind; however, undesirable physiological and pathological responses resulting from sleep insufficiency or sleep deprivation (SD) are becoming increasingly common. However, the influence of sleep deficiency on gut microbiota and microbiota-associated human diseases, especially on cardiac diseases remain controversial. Here, we constructed the experimental SD model in mice and found it significantly resulted in weakness, depression-like behaviors, and multiple organs dysfunction. Intriguingly, SD mice developed pathogenic cardiac hypertrophy and fibrosis with poor ejection fraction as well as fractional shortening. 16s rRNA sequencing demonstrated that SD-induced the pathogenic effects of gut microbiota, which was also observed in mice received by fecal microbe from SD mice in fecal microbiota transplantation (FMT) assays. Next, we investigated the therapeutic effects and underlying mechanisms of oxygen therapy in gut microbiota-associated cardiac fibrosis and dysfunction. The environment of 30% oxygen concentration effectively ameliorated the pathological effects on cardiac function. Transcriptome data also found oxygen therapy targeted several hypoxia-dependent pathways and suppressed cardiac collagen production. In conclusion, these results indicated the importance of sufficient sleep in gut microbiota and may represent a potential therapeutic strategy of oxygen environment exerts protective effects in sleepless sufferings through gut microbiota.

Intestinal tumor expression data from Apcmin/+ mice gavaged by feces from healthy controls or colorectal cancer patients

Project description:Colorectal cancer (CRC) is closely related to gut dysbiosis. We investigated the effects of imbalanced gut microbiota on the progression of intestinal adenoma in Apcmin/+ mice model using fecal microbiota transplantation (FMT). Administration of feces from CRC patients increased tumor proliferation and decreased apoptosis in tumor cells. Abnormal expression of genes related to Wnt-protein binding and lipid metabolic process was observed.

Regulation of Microglia-Mediated Neuroinflammation Post-Intracerebral Hemorrhage by Gut Microbiota and Short-Chain Fatty Acid Metabolism

Project description:Intracerebral hemorrhage (ICH) induces alterations in the gut microbiota composition, significantly impacting neuroinflammation post-ICH. However, the impact of gut microbiota absence on neuroinflammation following ICH-induced brain injury remain unexplored. Here, we observed that the gut microbiota absence was associated with reduced neuroinflammation, alleviated neurological dysfunction, and mitigated gut barrier dysfunction post-ICH. In contrast, recolonization of microbiota from ICH-induced SPF mice by transplantation of fecal microbiota (FMT) exacerbated brain injury and gut impairment post-ICH. Additionally, microglia with transcriptional changes mediated the protective effects of gut microbiota absence on brain injury, with Apoe emerging as a hub gene. Subsequently, Apoe deficiency in peri-hematomal microglia was associated with improved brain injury. Finally, we revealed that gut microbiota influence brain injury and gut impairment via gut-derived short-chain fatty acids (SCFA).

Persistent alterations in glucose metabolism, gut microbiome, and adipose tissue transcriptome after two-week sleep recovery in chronically sleep-fragmented female mice

Project description:Introduction: Chronic sleep fragmentation (SF) is prevalent in contemporary human society, highlighting detrimental effects on glucose metabolism and adipose tissue morphology, which is closely linked to gut microbiota composition. However, it remains unclear whether sleep recovery (SR) after prolonged SF can ameliorate glucose metabolism, influence the transcriptome of inguinal white adipose tissue (iWAT), and whether these effects align with alterations in the gut microbiota. Methods: Mice were subjected to 8 weeks of SF and subsequently allowed 2 weeks of SR. We assessed glucose tolerance through intraperitoneal glucose tolerance tests (ipGTT), analyzed gut microbiota via 16s rDNA amplicon sequencing, and examined transcriptomic alterations in iWAT using RNA sequencing. Results: Despite the two-week SR following chronic SF, significant glucose intolerance persisted, accompanied by subtle shifts in the gut microbiota and alterations in gene expression within iWAT. The top hub genes Ncapg, Cenpe, and Tik were identified from the protein-protein interaction network. Conclusion: Even followed by a brief period of SR, prolonged SF still led to ongoing glucose intolerance and alterations in the adipose tissue transcriptome in mice. These changes were intertwined with modifications in the gut microbiome. The shifts in gut microbiota may play a pivotal role in understanding the sustained negative effects of SF.

Transcriptomic signature of white adipose tissue from wild type and Acod1-deficient mice in response to high fat diet

Project description:Aconitate decarboxylase 1 (ACOD1) is the enzyme synthesizing itaconate, an immuno-regulatory metabolite tuning host-pathogen interactions. Such functions are achieved by affecting metabolic pathways regulating inflammation and microbe survival. However, at the whole-body level, metabolic roles of itaconate remain largely unresolved. By using multiomics-integrated approaches, here we show that ACOD1 responds to high-fat diet consumption in mice by promoting gut microbiota alterations supporting metabolic disease. Genetic disruption of itaconate biosynthesis protects mice against obesity, alterations in glucose homeostasis and liver metabolic dysfunctions by decreasing meta-inflammatory responses to dietary lipid overload. Mechanistically, fecal metagenomics and microbiota transplantation experiments demonstrate such effects are dependent on an amelioration of the intestinal ecosystem composition, skewed by high-fat diet feeding towards obesogenic phenotype. In particular, unbiased fecal microbiota profiling and axenic culture experiments point towards a primary role for itaconate in inhibiting growth of Bacteroidaceae and Bacteroides, family and genus of Bacteroidetes phylum, the major gut microbial taxon associated with metabolic health. Specularly to the effects imposed by Acod1 deficiency on fecal microbiota, oral itaconate consumption enhances diet-induced gut dysbiosis and associated obesogenic responses in mice. Unveiling an unrecognized role of itaconate, either endogenously produced or exogenously administered, in supporting microbiota alterations underlying diet-induced obesity in mice, our study points ACOD1 as a target against inflammatory consequences of overnutrition.

Multi-modal single cell analysis reveals gut microbiota reshapes brain immune landscape in aged mouse model.

Project description:We used 16S V3/V4 region amplification to evaluate the composition of bacteria species in mouse fecal pellets. Fecel pellets were collected from young-adult (12 weeks old) wild type C57Bl/6 mice and aged (72 weeks old) wild type C57Bl/6 mice after 21 days of vehicle or antibiotics treatment (to induce gut microbiota depletion). In one sequencing round, we sequenced a total of 12 different fecal samples (3 young control, 3 aged control, 3 young depleted gut microbiota (ABX) and 3 aged depleted gut microbiota (ABX)). Amplicons were indexed using the Nextera XT Index Kit and pooled into a library for Illumina sequencing.

SYISL affects fetal mice muscle fiber number by regulating maternal intestinal microbiota and their metabolites

Project description:The formation of embryonic muscle fibers during the prenatal period determines the number of muscle fibers after birth. Our previous studies showed that SYISL gene knockout (KO) mice significantly increased the number of total muscle fibers, but the underlying mechanism remains unclear. In this study, we found that the development of embryonic muscle fibers was significantly influenced by the interaction between host SYISL genotype and maternal gut microbiota. SYISL KO alters the composition of the female mice maternal gut microbiota, significantly increases the relative abundance of Prevotella (P<0.05). Fecal microbiota transplantation (FMT) experiments indicated that fecal suspension from KO female mice significantly increased the number of offspring muscle fibers. Our study provides the new evidence for the interaction between maternal single gene and gut microbiota on the embryonic muscle development of the offspring.
