Epigenome analysis of peripheral blood mononuclear cell (PBMC) samples from obstructive sleep apnea patients and healthy subjects

Project description:Genome wide DNA methylation profiling of obstructive sleep apnea (OSA) patients and healthy subjects. The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in peripheral blood mononuclear cell samples. Samples included 8 normal subjects and 16 patients with obstructive sleep apnea syndrome. Bisulphite converted DNA from the 21 samples were hybridized to the Illumina Infinium 27k Human Methylation Beadchip v1.2

Comparison of microRNA expression profiles in soft palate muscle of patients with OSAHS and chronic tonsillitis.

Project description:The expression profile of miRNAs in soft palate muscle of patients with OSAHS (obstructive sleep apnea/hypopnea syndrome) and chronic tonsillitis was examined using miRNA microarray analysis. Combining with the following real time PCR and bioinformatics analysis, the physiological importance of the miRNA-autophagy interconnection is far more likely to be elucidated.

Differential Expression and Correlation Analysis of Global Transcriptome for Obstructive Sleep Apnea Hypopnea Syndrome

Project description:In order to investigate the gene expression patterns and molecular regulatory mechanisms of obstructive sleep apnea hypopnea syndrome (OSAHS), the global transcriptome expression profiles of OSAHS patients and healthy people were analyzed using transcriptome sequencing technology. Differential expression of circular RNA, microRNA, long noncoding RNA, and messenger RNA was investigated between the two groups.

Obstructive sleep apnea is related to alterations in intestinal microbiome and impaired intestinal barrier function

Project description:Objectives: Obstructive Sleep Apnea (OSA) is related to repeated upper airway collapse, intermittent hypoxia, and intestinal barrier dysfunction. The resulting damage to the intestinal barrier may affect or be affected by the intestinal microbiota. Methods: A prospective case-control was used, including 48 subjects from Sleep Medicine Center of Nanfang Hospital. Sleep apnea was diagnosed by overnight polysomnography. Fecal samples and blood samples were collected from subjects to detect intestinal microbiome composition (by 16S rDNA gene amplification and sequencing) and intestinal barrier biomarkers – intestinal fatty acid-binding protein (I-FABP) and D-lactic acid (D-LA) (by ELISA and colorimetry, respectively). Results: The severity of OSA was related to differences in the structure and composition of the intestinal microbiome. Enriched Fusobacterium, Megamonasa, Lachnospiraceae_UCG_006, and reduced Anaerostipes was found in patients with severe OSA. Enriched Ruminococcus_2, Lachnoclostridium, Lachnospiraceae_UCG_006, and Alloprevotella was found in patients with high intestinal barrier biomarkers. Lachnoclostridium and Lachnospiraceae_UCG_006 were the common dominant bacteria of OSA and intestinal barrier damage. Fusobacterium and Peptoclostridium was independently associated with apnea-hypopnea index (AHI). The dominant genera of severe OSA were also related to glucose, lipid, neutrophils, monocytes and BMI. Network analysis identified links between the intestinal microbiome, intestinal barrier biomarkers, and AHI. Conclusions: The study confirms that changes in the intestinal microbiota are related to intestinal barrier biomarkers among patients in OSA. These changes may play a pathophysiological role in the systemic inflammation and metabolic comorbidities associated with OSA, leading to multi-organ morbidity of OSA.

Hsa_circ_0081065 exacerbates OSAHS-induced EndMT via regulating miR-665/HIF-1α signal axis and HIF-1α nuclear translocation

Project description:CircRNA is widely involved in various physiological and pathological biological processes. However, the function of circRNAs in obstructive sleep apnea hypopnea syndrome (OSAHS) has not been fully elucidated. Therefore, this study aims to investigate the key circRNA in OSAHS and clarify the molecular mechanism of it in OSAHS

Rat atria-2D LC-MS/MS - Atrial electrophysiological and molecular remodelling induced by obstructive sleep apnoea

Project description:To understand the molecular change occurring in the atria during obstructive sleep apnea, we have implemented a rat model of OSA involving the surgical implantation of a tracheal obstructive device, allowing the rats to remain conscious and free-roaming throughout 2 weeks of apnea administration. Rats were divided into severe and moderate apnea groups, receiving a 23 second or 13 second apneas per minute, respectively. The two-dimensional polyacrylamide gel electrophoresis (2D PAGE) of atrial homogenates to compare the dysregulations in the protein pattern in severe and moderate apnea when compared to control.

Serum proteomic analysis by tandem mass tags-based quantitative proteomics in pediatric obstructive sleep apnea

Project description:Pediatric obstructive sleep apnea (OSA) is a frequent respiratory disorder with an estimated prevalence of 3–6% in the general population. However, the underlying pathophysiology of OSA remains unclear. Recently, proteomic analysis using high-resolution and high-throughput mass spectrometry has been widely used in the field of medical sciences. In the present study, tandem mass tags (TMT)-based proteomic analysis was performed in the serum of patients with OSA.
