Project description:Congenital cytomegalovirus (cCMV) infection can damage the central nervous system in infants; however, its prognosis cannot be predicted from clinical evaluations at the time of birth. Urinary exosomes can be used to analyze neuronal damage in neuronal diseases. To investigate the extent of neuronal damage in patients with cCMV, exosomal miRNA expression in the urine was investigated in cCMV-infected infants and controls. Microarray analysis of miRNA was performed in a cohort of 30 infants, including 11 symptomatic cCMV (ScCMV), 7 asymptomatic cCMV (AScCMV), and one late-onset ScCMV cases, and 11 healthy controls (HC). Hierarchical clustering analysis revealed the distinct expression profile of ScCMV. The patient with late-onset ScCMV was grouped into the ScCMV cluster. Pathway enrichment analysis of the target mRNAs differed significantly between the ScCMV and HC groups; this analysis also revealed that pathways related to brain development were linked to upregulated pathways. Six miRNAs that significantly different between groups (ScCMV vs. HC and ScCMV vs. AScCMV) were selected for digital PCR in another cohort for further validation. Although these six miRNAs seemed insufficient for predicting ScCMV, expression profiles of urine exosomal miRNAs can reveal neurological damage in patients with ScCMV compared to those with AcCMV or healthy infants.

Project description:To investigate the possibility of using modern mass spectrometric methods for forecasting, early diagnosis of the causes of respiratory diseases, as well as monitoring the effectiveness of treatment of newborns with very low and extremely low birth weight infants. Results: Based on the analysis of literature data and the results of their own research into the application of modern mass spectrometric methods for early diagnosis of the causes of respiratory disease in preterm infants developed the design of the proteomic analysis of urine of infants revealed characteristic differences of proteome urine of newborn children with respiratory disorders of various origins

Project description:Objectives To compare hearing trajectories among children with symptomatic and asymptomatic congenital cytomegalovirus infection through age 18 years and to identify brain abnormalities associated with sensorineural hearing loss (SNHL) in asymptomatic case patients. Study Design Longitudinal prospective cohort study. Setting Tertiary medical center. Subjects and Methods The study included 96 case patients (4 symptomatic and 92 asymptomatic) identified through hospital-based newborn cytomegalovirus screening from 1982 to 1992 and 72 symptomatic case patients identified through referrals from 1993 to 2005. We used growth curve modeling to analyze hearing thresholds (0.5-8 kHz) by ear with increasing age and Cox regression to determine abnormal findings on head computed tomography scan associated with SNHL (hearing threshold ?25 dB in any audiometric frequency) among asymptomatic case patients. Results Fifty-six (74%) symptomatic and 20 (22%) asymptomatic case patients had SNHL: congenital/early-onset SNHL was diagnosed in 78 (51%) and 10 (5%) ears, respectively, and delayed-onset SNHL in 25 (17%) and 20 (11%) ears; 49 (32%) and 154 (84%) ears had normal hearing. In affected ears, all frequency-specific hearing thresholds worsened with age. Congenital/early-onset SNHL was significantly worse (severe-profound range, >70 dB) than delayed-onset SNHL (mild-moderate range, 26-55 db). Frequency-specific hearing thresholds were significantly different between symptomatic and asymptomatic case patients at 0.5 to 1 kHz but not at higher frequencies (2-8 kHz). Among asymptomatic case patients, white matter lucency was significantly associated with SNHL by age 5 years (hazard ratio, 4.4; 95% CI, 1.3-15.6). Conclusion Congenital/early-onset SNHL frequently resulted in severe to profound loss in symptomatic and asymptomatic case patients. White matter lucency in asymptomatic case patients was significantly associated with SNHL by age 5 years.

Project description:Purpose: The purpose of this study was to detect the expression profiles of circRNAs, lncRNAs and mRNAs in umbilical cord blood (UCB) exosomes from BPD infants. Methods:Microarray analysis was performed to compare the RNA profiles of UCB-derived exosomes from preterm newborn with and without BPD. Then, circRNA/lncRNA-miRNA-mRNA co-expression networks were built to determine their associations with BPD.Results:A total of 317 circRNAs, 104 lncRNAs, 135 mRNAs showed significant differential expression in UCB-derived exosomes from BPD preterm infants compared with the NBPD group. Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were conducted for examining differentially expressed exosomal circRNAs, lncRNAs and mRNAs. Our results showed the GO terms and KEGG pathways mostly involving differentially expressed exosomal RNAs were closely associated with endothelial or epithelial cell development. In addition, two networks were identified, including circRNA-circ_0086018/miR-762/MEN1 and lncRNA-BASP1-AS1/miR-20a-5p/DNAJC22 networks, which may take part in BPD.

Project description:Cystic Fibrosis is a life limiting disease due to mutations in the Cystic Fibrosis Conductance Gene Regulator (CFTR). This is associated with a multiorgan disease combining pancreatic insufficiency, chronic infected bronchopathy and production of a salty sweat. Increased survival of patients leads to observation of new complications, including proximal tubule transport dysfunctions with increased output of glucose, amino acids, phosphate, calcium, uric acid, and low Molecular Weight proteins, which ultimately triggers tubulo-interstitial injury and chronic kidney disease. (Jouret et al. 2007) Exosomes are membrane vesicles stemming from Multi-Vesicular Bodies. They reflect the biological state of the cell they stem from because they incorporate various bioactive molecules from their cell of origin, which can be transferred to target cells. They are therefore ideal biomarkers for early diagnosis, prediction of disease progression or response to treatment. Urinary exosomes have been largely investigated in kidney or urothelial diseases and exosomal proteins proved to be biomarkers reflecting renal cellular biology. We hypothetized that urinary exosomal proteins might be differentially expressed, according to the presence of the mutation in the CFTR gene and its correction. We analyzed urinary exosomes of patients with CF and healthy controls based on their protein content determined by high resolution mass spectrometry, in combination with Gene Set Enrichment Analysis. These results were compared to those obtained in exosomes collected in patients treated with CFTR modulators.
