Abstract
Disruption of circadian rhythms during fetal development may predispose mice to developing heart disease later in life. Here, we report that male, but not female, mice that had experienced chronic circadian disturbance (CCD) in utero were more susceptible to pathological cardiac remodeling compared with mice that had developed under normal intrauterine conditions. CCD-treated males showed ventricular chamber dilatation, enhanced myocardial fibrosis, decreased contractility, higher rates of induced tachyarrhythmia, and elevated expression of biomarkers for heart failure and myocardial remodeling. In utero CCD exposure also triggered sex-dependent changes in cardiac gene expression, including upregulation of the secretoglobin gene, Scgb1a1, in males. Importantly, cardiac overexpression of Scgb1a1 was sufficient to induce myocardial hypertrophy in otherwise naive male mice. Our findings reveal that in utero CCD exposure predisposes male mice to pathological remodeling of the heart later in life, likely as a consequence of SCGB1A1 upregulation.

Abstract
The thoracic and peritoneal cavities are lined by serous membranes and are home of the serosal immune system. This immune system fuses innate and adaptive immunity, to maintain local homeostasis and repair local tissue damage, and to cooperate closely with the mucosal immune system. Innate lymphoid cells (ILCs) are found abundantly in the thoracic and peritoneal cavities, and they are crucial in first defense against pathogenic viruses and bacteria. Nanomaterials (NMs) can enter the cavities intentionally for medical purposes, or unintentionally following environmental exposure; subsequent serosal inflammation and cancer (mesothelioma) has gained significant interest. However, reports on adverse effects of NM on ILCs and other components of the serosal immune system are scarce or even lacking. As ILCs are crucial in the first defense against pathogenic viruses and bacteria, it is possible that serosal exposure to NM may lead to a reduced resistance against pathogens. Additionally, affected serosal lymphoid tissues and cells may disturb adipose tissue homeostasis. This review aims to provide insight into key effects of NM on the serosal immune system.

Serum levels of club cell secretory protein (Clara) and short- and long-term exposure to particulate air pollution in adolescents. ENVIRONMENT INTERNATIONAL 2014; 68:66-70. [PMID: 24709782 DOI: 10.1016/j.envint.2014.03.011] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/22/2013] [Revised: 02/15/2014] [Accepted: 03/12/2014] [Indexed: 06/03/2023]
Abstract
BACKGROUND Studies in populations have shown that particulate air pollution is associated with changes in lung function in adolescents. OBJECTIVE We investigated the effect of short- and long-term exposure to particulate matter (PM10) on the pulmonary health of adolescents, using serum lung club cell secretory protein (Clara) (CC16) as a biomarker for respiratory epithelium integrity. METHODS We measured serum CC16 in 825 adolescents (57% girls, mean age: 15 years). Short-term and long-term exposure to ambient PM10 was estimated for each participant's home address using a kriging interpolation method. To explore the association between PM10 and serum CC16 we applied restricted cubic splines with 5 knots located at the 5th, 25th, 50th, 75th and 95th percentiles of the PM10 distribution. The explorative analyses showed a change in the slope of this association, after which a change-point analysis was performed. RESULTS After adjustment for potential covariates, the analysis showed strong associations between PM10 concentrations, averaged over the week preceding the clinical examination, and serum CC16 levels. Each 5 μg/m(3) increase in mean PM10 concentration in the week before the clinical examination was associated with a substantial increase of 0.52 μg/l (95% confidence interval: 0.31 to 0.73; p<0.0001) in serum CC16 levels. The association appears nonlinear with a flattening out of the slope at mean week PM10 levels above 37 μg/m(3). There was no evidence of an association between long-term exposure to PM10 and serum CC16 concentrations. CONCLUSIONS Our findings suggest that short-term exposure to particulate air pollution may compromise the integrity of the lung epithelium and lead to increased epithelial barrier permeability in the lungs of adolescents, even at low concentrations.

Abstract
Pleural effusion, an accumulation of pleural fluid, contains proteins originated from plasma filtrate and, especially when tissues are damaged, parenchyma interstitial spaces of lungs and/or other organs. This study details protein profiles in human pleural effusion from 43 lung adenocarcinoma patients by a two-dimensional nano-high performance liquid chromatography electrospray ionization tandem mass spectrometry (2D nano-HPLC-ESI-MS/MS) system. The experimental results revealed the identification of 1415 unique proteins from human pleural effusion. Among these 124 proteins identified with higher confidence levels, some proteins have not been reported in plasma and may represent proteins specifically present in pleural effusion. These proteins are valuable for mass identification of differentially expressed proteins involved in proteomics database and screening biomarker to further study in human lung adenocarcinoma. The significance of the use of proteomics analysis of human pleural fluid for the search of new lung cancer marker proteins, and for their simultaneous display and analysis in patients suffering from lung disorders has been examined.

Abstract
Pleural effusion, an accumulation of pleural fluid, contains proteins originating from plasma filtrate and, especially when tissues are damaged, parenchymal interstitial spaces of lungs and/or other organs. This report presents data of the first global proteomic analysis of human pleural effusion. A composite sample was prepared by pooling pleural effusions from seven lung adenocarcinoma patients. Two-dimensional gel electrophoresis analysis of the composite sample revealed 472 silver-stained spots. 242 selected gel spots were subjected to protein identification by in-gel digestion, liquid chromatography-tandem mass spectrometry, and sequence database search. 44 proteins were identified with higher confidence levels (at least two unique peptide sequences matched), while 161 other proteins were identified at the minimal confidence level (only one unique peptide sequence matched). The data provide fundamental information on the composition of protein contents in human pleural effusion. Among these 44 proteins that were identified with higher confidence levels, 7 proteins, retinoblastoma binding protein 7, synaptic vesicle membrane protein, corticosteroid binding globulin precursor, PR-domain containing protein 11, envelope glycoprotein, MSIP043 protein, and titin have not been reported in plasma and may represent proteins specifically present in pleural effusion. These proteins could have originated from parenchymal interstitial spaces and represent potential candidates of useful biomarkers that could not be readily detected in plasma but in pleural effusion. Retinoblastoma binding protein 7 is of special interest since it may play a role in the regulation of cell proliferation and differentiation.

Abstract
PURPOSE OF REVIEW The separation of pleural transudates from exudates, as the first step in the study of pleural effusions of unknown cause, is generally accepted as a useful practice. However, the optimal way to do this remains moot. RECENT FINDINGS New and more sophisticated biochemical markers have been proposed together, with new approaches to the interpretation of the results. Nevertheless, new studies have consolidated the criteria of Light et al. as those with a better accuracy. Effective diuresis increases the concentration of most pleural biochemical parameters used to differentiate transudates from exudates and appears as the main cause of the failures of this dichotomic approach. Among the alternative criteria proposed for identifying transudates in the setting of diuresis, the total protein gradient between serum and pleural fluid seems to be the most cost effective. SUMMARY Together with clinical judgment, the use of biochemical criteria seems mandatory. The criteria of Light et al. remain those of election. In the setting of effective diuresis, the use of the protein gradient is recommended. Although new and more sophisticated markers have been tested, it seems that looking for the causes of misclassification, when applying the criteria that to date have shown better efficiency, deserves preferential investigation.

Abstract
To determine the effect of exercise on serum levels of Clara cell protein (CC16) and surfactant-associated protein A (SP-A), serum was collected from 14 healthy subjects 1 h after maximal and sub-maximal exercise. Healthy volunteers participated on separate occasions in a control (no exercise) session, simulated firefighting tasks for 30 min (n=14), and intermittent treadmill exercise at near maximal heart rates for 60 min (n=10). Serum samples and induced sputum samples were collected 1 h post exercise. Induced sputum fluid was analyzed for tumor necrosis factor alpha (TNF-alpha), an inflammatory mediator produced by pulmonary macrophages. Serum CC16 levels increased significantly with both firefighting tasks (15+/-13 microg/L vs. 9+/-4 microg/L, P=0.047) and treadmill exercise (15+/-8 microg/L vs. 9+/-4 microg/L, P<0.01). Serum SP-A concentrations did not change compared to control with either firefighting tasks (247+/-106 microg/L vs. 247+/-96 microg/L, P=0.84) or treadmill exercise (251+/-89 microg/L vs. 285+/-87 microg/L, P=0.44). TNF-alpha concentrations in sputum supernatant showed no significant difference from controls. These results show an increase in serum CC16 after exercise. This must be considered when utilizing serum CC16 to determine the presence of lung injury in settings that combine exercise and toxic exposures.

Abstract
The proliferative response of cultured pulmonary mesothelial cells (MCs) to epithelial cell mitogens such as keratinocyte growth factor (KGF) and hepatocyte growth factor (HGF) is investigated. A cell line of rat pleural MCs and freshly prepared rat visceral and parietal MCs were studied. Both KGF and HGF stimulated thymidine uptake in the cell line when cultured for 2 d in serum-free conditions; the growth increase was magnified when tumor necrosis factor (TNF)-alpha was also added to the cultures. Adding asbestos fibers alone to MCs in culture did not enhance DNA synthesis by these cells. The MCs were also shown to synthesize significant amounts of HGF but much less KGF when cultured for 2 d. When freshly prepared MCs were examined, normal cell growth was more rapid in the parietal cells, which also had a more epithelial-type morphology. The addition of HGF and KGF resulted in increased DNA synthesis in each cell type, but no effect of added TNF-alpha was found. The results indicate that pulmonary MCs have the potential to proliferate in response to cytokines such as HGF and KGF that are usually associated with epithelial cell regeneration after injury.

Abstract
1. The alveolocapillary membrane faces an extraordinary task in partitioning the plasma and lung hypophase proteins, with a surface area approximately 50-fold that of the body and only 0.1-0.2 micron thick. 2. Lung permeability is compromised under a variety of circumstances and the delineation between physiological and pathological changes in permeability is not always clear. Although the tight junctions of the epithelium, rather than the endothelium, are regarded as the major barrier to fluid and protein flux, it is becoming apparent that the permeability of both are dynamically regulated. 3. Whereas increased permeability and the flux of plasma proteins into the alveolar compartment has dire consequences, fortuitously the flux of surfactant proteins from the airspaces into the circulation may provide a sensitive means of non-invasively monitoring the lung, with important implications for treatment modalities. 4. Surfactant proteins are unique in that they are present in the alveolar hypophase in high concentrations. They diffuse down their vast concentration gradients (approximately 1:1500-7000) into the circulation in a manner that reflects lung function and injury score. Surfactant proteins vary markedly in size (approximately 20-650 kDa) and changes in the relative amounts appear particularly diagnostic with regard to disease severity. Alveolar levels of surfactant proteins remain remarkably constant despite respiratory disease and, unlike the flux of plasma proteins into the alveolus, which may reach equilibrium in acute lung injury, the flux of surfactant proteins is unidirectional because of the concentration gradient and because they are rapidly cleared from the circulation. 5. Ultimately, the diagnostic usefulness of surfactant proteins as markers of alveolocapillary permeability will demand a sound understanding of their kinetics through the vascular compartment.

Abstract
Surfactant proteins A and B (SP-A and SP-B) enter the circulation in a manner that acutely reflects changes in pulmonary function in patients with acute respiratory failure (ARF). There is a small but significant gradient in SP-A and SP-B from arterial to mixed venous (A-V) blood, and since we have detected both proteins in urine, the kidney may be a major site of their systemic clearance. Clara cell secretory protein 16 (CC16), which leaks from the respiratory tract, is known to be freely eliminated by the kidney. Lung plasma protein levels will depend on the rates of both protein entry into and clearance from plasma. In order to study the limiting variable determining these levels, we compared plasma CC16, SP-A, and SP-B in matching A-V blood samples from 37 ARF patients with indices of lung dysfunction and glomerular filtration rate (GFR) (of plasma cystatin C and creatinine). Cystatin C, CC16, SP-A, and SP-B were reduced in mixed venous plasma (all p < 0.001) and their A-V gradients were directly related to their arterial levels (all p < 0.03). Whereas CC16, SP-A, and SP-B reflected blood oxygenation (all p < 0.05), only SP-A and SP-B were related to lung injury score (LIS) (both p < 0.05). In contrast, whereas the clearances of both CC16 and cystatin C were related to that of creatinine (p < 0.02 for both), the clearances of SP-A and SP-B were not. Our study confirms that all three lung proteins are acutely cleared from the circulation of patients with ARF (half-lives < 18 min), and we conclude that whereas the plasma concentration of CC16 depends on GFR, plasma concentrations of SP-A and SP-B reflect lung function independently of this variable.
