(Submitter supplied) Matrix metalloproteinase-9 (MMP-9) expression is up-regulated in alveolar macrophages (AM) of HIV1+ smokers who develop emphysema. Based on the knowledge that lung epithelial lining fluid (ELF) of HIV1+ smokers has increased levels of inflammatory cytokines compared to HIV1- smokers, we hypothesized up-regulation of lung cytokines in HIV1+ smokers may be functionally related to increased MMP-9 expression. more...

(Submitter supplied) Background: Vitamin D is associated with lung health in epidemiologi studies, but mechanisms mediating observed associations are poorly understood. This study explores mechanisms for an effect of vitamin D in lung through an in vivo gene expression study, an expression quantitative trait loci (eQTL) analysis in lung tissue, and a population-based cohort study of sequence variants. Methods: Microarray analysis investigated the association of gene expression in small airway epithelial cell with serum 25[OH]D in adult nonsmokers. more...

(Submitter supplied) Motivation: Computational inference methods that make use of graphical models to extract regulatory networks from gene expression data can have difficulty reconstructing dense regions of a network, a consequence of both computational complexity and unreliable parameter estimation when sample size is small. As a result, identification of hub genes is of special difficulty for these methods.Methods: We present a new algorithm, Empirical Light Mutual Min (ELMM), for large network reconstruction that has properties well suited for dense graph recovery. more...

(Submitter supplied) In the context that HOX mutant mice have profound deficits in airway branching morphogenesis, we asked whether the positional identity of HOX genes is maintained in the epithelium of the adult human tracheobronchial tree and if so, whether these positional differences are embedded in the stem/progenitor population derived from nonbranching vs branching airways. We found that 10 of 39 HOX genes are expressed in varying degrees in the nonbranching (trachea) or branching (large and small airways) human airway epithelium. more...

(Submitter supplied) Background: Cases where genotype-phenotype relationships depend on environmental factors have been quantified for many complex diseases. Such genotype-environment interactions (GEI or GxE) may also affect expression Quantitative Trait Loci (eQTL) present in tissues critical for the manifestation of disease. To assess this hypothesis, we performed an analysis of eQTL-GEI resulting from an individual's smoking environment in the lung small airway epithelium (SAE). more...

(Submitter supplied) CXCL14, a recently described chemokine constitutively expressed in various epithelia, has multiple putative roles in inflammation and carcinogenesis. Based on the knowledge that cigarette smoking and the smoking-induced disorders, such as chronic obstructive pulmonary disease (COPD) and lung cancer, are associated with inflammation, we hypothesized that the airway epithelium, the primary site of smoking-induced pathologic changes in COPD and adenocarcinoma, responds to cigarette smoking with an altered CXCL14 gene expression as a part of disease-relevant molecular phenotype. more...

(Submitter supplied) Testican 3 (coded for by SPOCK3), is an extracellular matrix heparan/chondroitin sulphate proteoglycan that possesses serine and cysteine protease inhibitor-like domains Based on the knowledge that serine proteases contribute to the destruction of the lung in cigarette smokers, but that only a fraction of smokers develop smoking-induced lung disease, we hypothesized that smokers expressed SPOCK3 at lower levels in the small airway epithelium, the initial site of smoking-induced disease, and further, that genetic variability modulates the expression of SPOCK3 in the airway epithelium. more...

(Submitter supplied) There is evidence of pathophysiologic diversity in chronic rhinosinusitis with nasal polyps (CRSwNP), but data characterizing the molecular endotypes of CRSwNP and their association with treatment is lacking. The objective of this study was to identify gene signatures associated with CRSwNP endotypes, clinical features, and dupilumab treatment response. Two distinct transcriptional clusters (C1 and C2) were identified, both with elevated type 2 biomarkers. more...

(Submitter supplied) Parabens have been used for decades as preservatives in food, drugs and cosmetics. The majority however, were banned in 2009 and 2014 leaving only methyl-, ethyl-, propyl-, and butyl-derivates available for subsequent use. Methyl- and propylparaben have been extensively tested in vivo, with no resulting evidence for developmental and reproductive toxicity (DART). In contrast, ethylparaben has not yet been tested for DART in animal experiments, and it is currently debated if additional animal studies are warranted. more...

(Submitter supplied) Penetration of immune cells into tumor cells was believed to be immune-suppressive via cell-in-cell (CIC) mediated death of the internalized immune cells. We unexpectedly found that CIC formation largely led to the death of the host tumor cells, but not the internalized immune cells, manifesting typical features of death executed by NK cells, which we called “in-cell killing” that demonstrates efficacy superior to the canonical way of “kiss killing” from outside. more...

(Submitter supplied) The deposited microarray data were generated in a study that integrated the gene expression profiles and metabolic responses of Caco2 cells incubated with Bifidobacterium infantis subsp. infantis and Salmonella enterica subsp. enterica sv. Typhimurium. The aim of this study was to investigate the interaction of B. infantis, S. Typhimurium, and host cells (Caco2) in the course of infection to understand the molecular mechanics of probiotic-pathogen-host interactions.

(Submitter supplied) Deubiquitinating enzymes (DUBs) are divided into seven subgroups based on sequence and structure and perform the roles of mediating the deubiquitination of substrate proteins, regulating protein function, and participating in various cellular life activities. Among them, the ubiquitin-specific protease family (USP) is the DUB subtype with the most members and structural diversity discovered so far. USP48 is a member of the USP family of ubiquitin-specific proteases and has been found to promote glioblastoma by deubiquitinating the Gli1 transcription factor and to promote the progression of non-small-cell lung cancer through inhibition of the Wnt/β-catenin signaling pathway. We used microarrays to detail changes in gene expression regulated by USP48 overexpression in HCC cells.

(Submitter supplied) Several groups reported the correlation between hypermethylation of RASSF1A and aggressiveness or a poor outcome in various pediatric tumors, including Wilms tumor. In addition, it is known that the overexpression of RASSF1A promotes apoptotic cell cycle arrest and reduces the tumorigenicity. In an attempt to identify epigenetic targets related to the biological features of rhabdoid tumor of the kidney (RTK), we analyzed the methylation level of the RASSF1A gene in RTK. more...
