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

ABSTRACT: 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.

DNA methylation profiling in blood of OSA patients and controls

Project description:Obstructive sleep apnea (OSA) is associated with increased risk for cardiovascular morbidity and mortality. Epidemiological and animal models studies generate hypotheses for innovative strategies in OSA management by interfering intermediates mechanisms associated with cardiovascular complications. In this study, we interrogated DNA methylation profiles in 16 polysomnographically evaluated OSA patients (Apnea Hypopnea Index, AHI > 30) and 8 controls (AHI<5 events/h sleep). Blood samples were collected at initial visit (V1) and a year later (V2). OSA patients received Continuous Positive Air Pressure (CPAP) therapy with high adherence (> 4 hours/night). Control individuals did not receive CPAP therapy. Genomic DNA was treated with sodium bisulfite. Converted DNA was analyzed using Illumina’s Infinium Human Methylation 450 BeadChip assay. DNA methylation profiles enabled the prospective evaluation of inflammatory and epigenetics mechanism involved in cardiovascular complication of OSA patients compared with non OSA subjects, as well as the variation of epigenetic profiles in OSA patients after one year of high-adherence CPAP therapy.

Effects of CPAP Therapy on Leukocyte Gene Expression

Project description:Rationale: Obstructive sleep apnea (OSA) has been associated with a number of chronic disorders that may improve with effective therapy. However, the molecular pathways affected by continuous positive airway pressure (CPAP) treatment are largely unknown. We sought to assess the system-wide consequences of CPAP therapy by transcriptionally profiling peripheral blood leukocytes (PBLs). Methods: Subjects diagnosed with severe OSA were treated with CPAP, and whole-genome expression measurement of PBLs was performed at baseline and following therapy. We used Gene Set Enrichment Analysis (GSEA) to identify gene sets that were differentially enriched. Network analysis was then applied to identify key drivers of pathways influenced by CPAP. Results: 18 subjects with severe OSA (apnea hypopnea index ≥ 30 events/hour) underwent CPAP therapy and microarray analysis of their PBLs. Treatment with CPAP improved AHI, daytime sleepiness and blood pressure but did not affect anthropometric measures. GSEA revealed a number of enriched gene sets, many of which were involved in neoplastic processes and displayed down-regulated expression patterns in response to CPAP. Network analysis identified several densely connected genes that are important modulators of cancer and tumor growth. Conclusions: Effective therapy of OSA with CPAP is associated with alterations in circulating leukocyte gene expression. Functional enrichment and network analyses highlighted transcriptional suppression in cancer-related pathways suggesting potentially novel mechanisms linking OSA with neoplastic signatures. Total RNA from peripheral blood leukocytes of 18 subjects with severe sleep apnea at baseline and after effective CPAP therapy was hybridized to 36 Affymetrix Genechip Human Gene 1.0 ST microarrays

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.

Transcriptional survey of peripheral blood links lower oxygen saturation during sleep with reduced expressions of CD1D and RAB20 that is reversed by CPAP therapy

Project description:Sleep Disordered Breathing (SDB) is associated with a wide range of physiological changes, likely due in part to the influence of hypoxemia during sleep on gene expression. We studied gene expression in peripheral blood mononuclear cells in association with three measures of SDB: the Apnea Hypopnea Index (AHI); average oxyhemoglobin saturation (avgO2) during sleep; and minimum oxyhemoglobin saturation (minO2) during sleep. We performed discovery analysis in two community-based studies: the Multi-Ethnic Study of Atherosclerosis (MESA; N = 580) and the Framingham Offspring Study (FOS; N=571). Associations with false discovery rate (FDR) q-value<0.05 in one study were considered to have replicated if a p-value<0.05 was observed in the other study. Associations that replicated between cohorts, or with FDR q-value<0.05 in meta-analysis of the two studies, were carried forward for gene expression analysis in the blood of 15 participants from the Heart Biomarkers In Apnea Treatment (HeartBEAT) trial who had moderate or severe obstructive sleep apnea (OSA) and were studied before and after three months of treatment with continuous positive airway pressure (CPAP). We also performed Gene Set Enrichment Analysis based on all trait and cohort analyses. We identified 22 genes associated with SDB traits in both MESA and FHS. Of these, lower CD1D and RAB20 expressions were associated with lower avgO2 in MESA and FHS, and CPAP treatment increased their expression in HeartBEAT. Immunity and inflammation pathways were up-regulated in subjects with lower avgO2, i.e. in those with a more severe SDB phenotype (MESA), whereas immuno-inflammatory processes were down-regulated in response to CPAP treatment (HeartBEAT).

Expression data from mouse aorta with chronic intermittent hypoxia exposure

Project description:Atherosclerosis is the pathological basis of cardiovascular disease. Obstructive sleep apnea aggravates atherosclerosis, and chronic intermittent hypoxia (CIH) as a prominent feature of obstructive sleep apnea plays an important role during the process of atherosclerosis. The mechanisms of CIH in the development of atherosclerosis remain unclear. The microarray was used to investigate differentially expressed mRNAs and long noncoding RNAs (lncRNAs) in aorta from five groups of ApoE-/- mice fed with a high-fat diet and exposed to various conditions: normoxia for 8 weeks, CIH for 8 weeks, normoxia for 12 weeks, CIH for 12 weeks, or CIH for 8 weeks followed by normoxia for 4 weeks.
