Project description:Background: Right ventricular (RV) and left ventricular (LV) myocardium differ in their response to pressure-overload hypertrophy (POH). In this report we use microarray and proteomic analyses to identify pathways modulated by LV-, and RV-POH in the immature heart. Methods: Newborn New Zealand White rabbits underwent banding of the descending thoracic aorta (LV-POH; n=6). RV-POH was achieved by banding the pulmonary artery (n=6). Sham–control animals (SC; n=6 each) were sham-manipulated. Following 4 (LV-POH) and 6 weeks (RV-POH) recovery, the hearts were removed and matched sample RNA and proteins were isolated for microarray and proteomic analysis. Results: There was no difference in body weight in RV-, LV-POH vs. SC but there was a significant increase vs. SC in RV (3.2±0.8g vs. 1.2±0.3g; P<0.01) and LV weight (7.08±0.6g vs. 4.02±0.2g; P<0.01). Fractional area change (RV-POH) and shortening fraction (LV-POH) decreased significantly (23±6 vs. 47±6 and 21±4 vs.44±2, respectively, P<0.01). Microarray analysis demonstrated that LV-POH enriched pathways for oxidative phosphorylation, mitochondria energy pathways, actin, ILK, hypoxia, calcium and protein kinase-A signalling. RV-POH enriched pathways for cardiac oxidative phosphorylation. Proteomic analysis revealed 19 proteins were uniquely expressed in LV-POH vs. SC. Functional annotation clustering analysis indicated significant enrichment for the mitochondrion, cellular macromolecular complex assembly and oxidative phosphorylation. RV-POH had 15 uniquely expressed proteins vs. SC. Functional annotation clustering analysis indicated significant enrichment in structural constituents of muscle, cardiac muscle tissue development and calcium handling. Conclusion: Our results identify unique transcript and protein expression profiles in LV, RV-POH and provide new insight into the biological basis of ventricular specific hypertrophy. 3 different conditions: PAB-RV vs. Sham-control RV, PAB-RV [test] vs. PAB-LV [control], AOB-LV vs. Sham-control LV.

Project description:Background: Adults with at least one copy of the minor allele in the rs6967330 SNP (AA/AG) in the rhinovirus (RV) receptor Cadherin related family member 3 gene (CDHR3), have a higher risk for CRS than those with two copies of the major allele (GG). Objective: To determine if the rs6967330 SNP increased the risk for acute exacerbations of chronic rhinosinusitis (AECRS) in adults and identify if their nasal cells showed a distinct pathophysiologic process activated by RV infection. Methods: We recruited adults with CRS (AG/AA,n=17; GG,n=37) and at baseline collected sinonasal outcome tests (SNOT-22), objective endoscopy scores, and nasal brushings for cells and RV viral detection. Subjects were contacted every two weeks for AECRS over one year, and if symptomatic this data was re-collected. To determine the effect of the rs6967330 SNP, air-liquid-interface (ALI) cultures were derived from nasal samples (AG/AA,n=19; GG,n=19). Cytokines and RNA transcriptome responses were measured 48 hours-post viral challenge with RV-A, RV-B, and RV-C. Results: During AECRS, adults with the AA/AG allele had 1.6x higher SNOT-22 scores, 2x higher endoscopic scores, and were 4x more likely to have RV infections during AECRS than those with the GG allele. (AA/AG) ALI cultures had significantly greater virus replication of RV-A (2.4x) and RV-C (3.5x) but not RV-B, higher levels of inflammatory cytokines, and significantly increased interferon-related pathways compared to (GG) ALI cultures. Conclusions: The minor allele in the rs6967330 SNP increases the risk for AECRS disease severity and is associated with an aberrant interferon-mediated inflammatory response to both RV-A and RV-C infections.

Project description:To analyze the effect of Glycoprotein 130 in small diameter sensory neurons, dorsal root ganglia (DRG) of conditional SNS-gp130-/- and control (gp130fl/fl) mice were collected and mRNA expression profiles were compared between the two groups. DRG samples of two littermate mice were always pooled and a total of 10 gp130fl/fl and 10 SNS-gp130-/- mice were divided into 5 groups per genotype. Expression of transcripts were analyzed using the Applied Biosystems microarray platform AB1700 (Mouse Genome Survey Microarray V2.0).

Project description:Inflammatory hepatocellular adenomas (IHCA) are benign liver tumours defined by the presence of inflammatory infiltrates and by the elevated expression of inflammatory proteins in tumour hepatocytes1,2. Here we show a striking activation of the IL6 signalling pathway in this tumour type, and sequencing candidate genes pinpointed this response to somatic gain-of-function mutations in the IL6ST gene that encodes the signalling co-receptor gp130. Indeed, ~70% of IHCA harbour small in-frame deletions that target the binding site of gp130 for IL6, and expression of the most frequent gp130 mutant, Delta-STVY190, in hepatocellular cells activates STAT3 in absence of ligand. Further, analysis of hepatocellular carcinomas revealed rare gp130 alterations always accompanied by ß-catenin-activating mutations, suggesting a cooperative effect of these signalling pathways in the malignant conversion of hepatocytes. The recurrent gain-of-function gp130 mutations in these human hepatocellular adenomas explains their inflammatory phenotype, and suggest that similar alterations may occur in other inflammatory epithelial tumours with STAT3 activation.

Project description:Arrhythmogenic cardiomyopathy (AC) is an inherited cardiomyopathy characterized by fibrofatty replacement predominantly involved in right ventricle and clinically by ventricular arrhythmias.In this study, we set out to characterize the cardiac novel long-noncoding RNAs using deep RNA sequencing data from human heart tissues. Particularly, we identified AC specific novel lncRNAs that contribute to AC pathophysiology by comparing the lncRNAs transcripts of nine AC explanted hearts (RV), five non-diseased donor hearts (RV), four non-AC failing hearts (dilated cardiomyopathy, RV). To dissect the roles of novel lncRNAs in ARVC from LV, we also include six non-diseased donor hearts (LV) and six ARVC explanted hearts (LV) in the analysis. In the identified novel AC lncRNAs, a large part of them are derived from enhancer regions and acting as cis- elements to potentially regulate lipogenesis or lipid metabolism related genes. Finally, we validated several of these AC specific novel lncRNAs and their potential targets in independent patient samples. Collectively, we identified high-confidence AC specific novel lncRNAs from human samples and suggest their potential roles as cis- elements in AC pathology. Further study of these novel AC lncRNAs could provide new opportunities for diagnosis and therapeutic intervention.
