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.

Project description:<p>To identify the potential iWAT-derived adipokines that regulate intestinal IgA biosynthesis, we conducted untargeted metabolomics in the serum of iFR and iSham mice. A total of 214 differential abundant metabolites were identified (log2FC >1 or <-1 and adjusted p-value <0.05) between the two groups. Pathway analysis showed that retinol metabolism was the most significantly altered pathway by iWAT removal. Despite retinol level remained unchanged, its downstream oxidized products, including retinal, RA, and all-trans-5,6-epoxy-RA, were significantly downregulated in the iFR mice. The reduction of RAs was further confirmed through using a targeted LC-MS/MS analysis. </p>

Project description:There is a regional preference around lymph nodes (LNs) for adipose beiging upon cold exposure. However, the importance of this unique anatomical location remains poorly understood. In this study, the potential role of Lymph nodes in iWAT was investigated. to elucidate functional outcomes, we performed RNA-sequencing analysis using littermate sham and lymph nodes removal (LNR) mice upon cold exposure

Project description:Background: Sleep is fundamental to growth, immune function, and overall health. We initiate our study to elucidate the impact of sleep fragmentation (SF) on the cardiac function, gut microbiome diversity, and the transcriptomic profile of inguinal white adipose tissue (iWAT) in mice, as well as the regulatory role of a high protein diet. Methods: We constructed chronic SF and high protein diet intervention mouse models for this research. Cardiac structure and function were evaluated by echocardiographic analyses. Gut microbiota composition was determined by 16s rDNA amplicon sequencing. Transcriptome alterations of iWAT were assessed by RNA-sequencing. Results: Our result revealed that SF interventions induced inflammatory changes in adipose tissue and perturbed the diversity and composition of the gut microbiota. Concurrently, 6-week SF intervention led to a significant decline in left ventricular systolic function in mice, manifested by a notable decrease in EF and FS. Masson staining revealed distinctions compared to the control group, suggesting an increase in myocardial collagen fiber content following SF intervention. High-protein diet intervention partially mitigated the damage to cardiac structure and function caused by SF. Meanwhile, high-protein diet coupled with improvements in the adipose tissue transcriptome changes induced by SF. Conclusions: In conclusion, chronic SF intervention induced cardiac damage, alters gut microbiota composition and induce adipose tissue inflammation. High-protein diet could partially mitigate the changes above.
