Colorectal Cancer Screening in Cystic Fibrosis

Project description:This multi-center study will compare multi-target DNA and quantitative FIT stool-based testing to colonoscopy in individuals with Cystic Fibrosis (CF) undergoing colon cancer screening with colonoscopy. The primary endpoint is detection of any adenomas, including advanced adenomas and colorectal cancer (CRC).

Metaproteomic analysis of gut microbiota from 30 samples of cystic fibrosis infants

Project description:The link between human gut microbiota (a complex group of microorganisms including not only bacteria but also fungi, viruses, etc.,) and the physiological state is nowadays unquestionable. Metaproteomic has emerged as a useful technique to characterize this microbial community, not just taxonomically, but also focusing on specific biological processes carried out by gut microbiota that may have an effect in the host health or pathological state. Cystic fibrosis is a genetic disease in which the microbiota of the respiratory tract determines the patient's survival and differences in composition of gut microbiota of cystic fibrosis patients respect to healthy infants have been reported. In order to characterize this host-microbiota inter-relation, we carried out the metaproteomic study of 30 stool samples from infants with cystic fibrosis.

Expression data of cystic fibrosis and non-cystic fibrosis airway cell lines under oxidative stress

Project description:CF's physiopathology is poorly explained by the mutation alone. The oxydative stress could be a major factor of this illness . Study its impact on transcriptome's CF cell line could be ameliorate our understanding of the evolution of cystic fibrosis. we used microarray technology to evaluate under oxydative stress, the transcriptional state of an epithelial lung cell issued from a human with cystic fibrosis and to identify a set of modulated genes associated to survival cell processes. the two cell lines are cultivated to Air-liquid Interface for RNA extraction and hybridization on Affymetrix microarrays. Each condition is triplicated. For the oxidative stress conditions, the two cell lines are treated on apical site by 15 µl of DMNQ (2,3-dimethoxy-1,4-naphtoquinone) ,concentrated at 15 µM, during 24 hours before RNA extraction.

Whole blood gene expression to predict susceptibility to nontuberculous mycobacterial pulmonary disease in adults with cystic fibrosis

Project description:Background: Patients with cystic fibrosis (CF) have an elevated lifetime risk of infection and disease caused by nontuberculous mycobacteria (NTM). Currently, there is no method to predict whether patients with cystic fibrosis will develop disease related to non-tuberculous mycobacteria. In non cystic fibrosis populations, several genetic susceptibility factors have been described. In this study, we examined whether patients with cystic fibrosis demonstrate a similar pattern of genetic susceptibility and explored host immune-related biomarkers predictive of NTM pulmonary disease (NTM-PD). Methods: We evaluated whole blood gene expression using bulk RNA-seq in a cohort of CF patients at the time of first isolation of NTM. Differential gene expression was compared in patients who did (n = 12) vs. did not (n= 30) develop NTM-PD following first NTM growth. Results: No differences in demographics or composition of white blood cell sample populations at the time of sample collection were identified between groups. There were no significant differences in the expression of genes previously reported to confer susceptibility to NTM-PD in non-CF populations. However, CF patients who went on to develop NTM-PD had higher expression of genes involved in the interferon ( and ), tumor necrosis factor, and IL6 STAT3 JAK pathways. Conclusion: Patients with CF who develop NTM-PD have increased expression of genes involved in innate immunity, in contrast to non-CF populations where these responses seem to be suppressed.

Environmental exposures and inflammation in young children with cystic fibrosis

Project description:Secondhand smoke exposure (SHSe) is a common environmental factor known to increase asthma severity and respiratory infections in children, as well disrupt metabolic signals and host immune responses in patients with cystic fibrosis (CF). This study defines biomarkers and metabolic profiles of SHSe (includes ENDS exposure) in the young CF population and determines how SHSe impacts regulation of infection, inflammation, and respiratory health.

Gene expression of immortalized cystic fibrosis and non-cystic fibrosis airway epithelial cells

Project description:Our laboratory has held a long interest in the glycosylation changes seen on the surface of airway epithelia of patients with the disease cystic fibrosis (CF). Experiments from our laboratory have detailed a CF glycosylation phenotype of increased Fuca1,3/4 and decreased Fuca1,2 and sialic acid on the surfaces of immortalized and primary CF cells compared to non-CF cells. Further, we have shown that gene transfer and subsequent expression of a wild type CF plasmid in CF airway cells results in correction or reversal of this glycosylation phenotype. We hypothesize that the changes in glycosylation seen in CF cells are key in the pathophysiology of the cystic fibrosis airway disease. For example, it has been shown that Pseudomonas aeruginosa, a bacterium that has a predilection for colonizing CF airways, adheres to asialylated glycolipids and glycoconjugates with terminal Fuca1,3/4. One focus of our laboratory is to elucidate the etiology of the glycosylation changes seen in CF cells and the mechanism by which these changes are reversed by wild type CFTR gene transfer. We propose to study the gene expression of immortalized and primary CF and non-CF airway epithelial cells: 1. CF/T43 vs. BEAS-2B cells. These are two widely used immortalized airway cell lines that we have used extensively in the past. 2. C38 cells; C38 cells are IB3 cells expressing wtCFTR. The experimental focus is to elucidate the etiology of the glycosylation changes seen in Cystic Fibrosis (CF) cells and the mechanism by which these changes are reversed by wild type CFTR gene transfer. To do so, the gene expression of immortalized and primary CF and non-CF airway epithelial cells were compared and studied. Cell lines used were CF/T43 and BEAS-2B, both widely used immortalized airway cell lines. Other cell lines studied included C38 cell lines (clonal derivatives of IB3 cells expressing wtCFTR).
