CEBP-β and PLK1 as Potential Mediators of the Breast Cancer/Obesity Crosstalk: In Vitro and In Silico Analyses.

Over the last two decades, obesity has reached pandemic proportions in several countries, and expanding evidence is showing its contribution to several types of malignancies, including breast cancer (BC). The conditioned medium (CM) from mature adipocytes contains a complex of secretes that may mimic the obesity condition in studies on BC cell lines conducted in vitro. Here, we report a transcriptomic analysis on MCF-7 BC cells exposed to adipocyte-derived CM and focus on the predictive functional relevance that CM-affected pathways/processes and related biomarkers (BMs) may have in BC response to obesity.

Smooth Muscle Cell Phenotypic Switch Induced by Traditional Cigarette Smoke Condensate: A Holistic Overview.

Cigarette smoke (CS) is a risk factor for inflammatory diseases, such as atherosclerosis. CS condensate (CSC) contains lipophilic components that may represent a systemic cardiac risk factor. To better understand CSC effects, we incubated mouse and human aortic smooth muscle cells (SMCs) with CSC.

BAL Proteomic Signature of Lung Adenocarcinoma in IPF Patients and Its Transposition in Serum Samples for Less Invasive Diagnostic Procedures.

Idiopathic pulmonary fibrosis (IPF) is a form of chronic and irreversible fibrosing interstitial pneumonia of unknown etiology. Although antifibrotic treatments have shown a reduction of lung function decline and a slow disease progression, IPF is characterize by a very high mortality. Emerging evidence suggests that IPF increases the risk of lung carcinogenesis.

Neurodegenerative Disorder Risk in Krabbe Disease Carriers.

Krabbe disease (KD) is a rare autosomal recessive disorder caused by mutations in the galactocerebrosidase gene (). Defective GALC causes aberrant metabolism of galactolipids present almost exclusively in myelin, with consequent demyelinization and neurodegeneration of the central and peripheral nervous system (NS). KD shares some similar features with other neuropathies and heterozygous carriers of mutations are emerging with an increased risk in developing NS disorders.

Changes in serum metabolomics in idiopathic pulmonary fibrosis and effect of approved antifibrotic medication.

Idiopathic pulmonary fibrosis (IPF) is a progressive disease with significant mortality and morbidity. Approval of antifibrotic therapy has ameliorated disease progression, but therapy response is heterogeneous and to date, adequate biomarkers predicting therapy response are lacking. In recent years metabolomic technology has improved and is broadly applied in cancer research thus enabling its use in other fields.

Serum Proteomic Profile of Asthmatic Patients after Six Months of Benralizumab and Mepolizumab Treatment.

Severe eosinophilic asthma is characterized by chronic airway inflammation, oxidative stress, and elevated proinflammatory cytokines, especially IL-5. Mepolizumab and benralizumab are both humanized IgG antibodies directed against IL-5 signaling, directly acting on eosinophils count. Together with the complexity of severe asthma classification and patient selection for the targeted treatment, there is also the urgency to clarify the follow-up of therapy to identify biomarkers, in addition to eosinophils, for the optimal duration of treatment, persistence of effectiveness, and safety.

A Novel Ex Vivo Approach Based on Proteomics and Biomarkers to Evaluate the Effects of Chrysene, MEHP, and PBDE-47 on Loggerhead Sea Turtles ().

The principal aim of the present study was to develop and apply novel ex vivo tests as an alternative to cell cultures able to evaluate the possible effects of emerging and legacy contaminants in . To this end, we performed ex vivo experiments on non-invasively collected whole-blood and skin-biopsy slices treated with chrysene, MEHP, or PBDE-47. Blood samples were tested by oxidative stress (TAS), immune system (respiratory burst, lysozyme, and complement system), and genotoxicity (ENA assay) biomarkers, and genotoxic and immune system effects were observed.

Alteration of Serum Proteome in Levo-Thyroxine-Euthyroid Thyroidectomized Patients.

The monotherapy with levo-thyroxine (LT4) is the treatment of choice for patients with hypothyroidism after thyroidectomy. However, many athyreotic LT4-treated patients with thyroid hormones in the physiological range experience hypothyroid-like symptoms, showing post-operative, statistically significant lower FT3 levels with respect to that before total thyroidectomy. Since we hypothesized that the lower plasmatic FT3 levels observed in this subgroup could be associated with tissue hypothyroidism, here we compared, by a preliminary proteomic analysis, eight sera of patients with reduced post-surgical FT3 to eight sera from patients with FT3 levels similar to pre-surgery levels, and six healthy controls.

First Attempt to Couple Proteomics with the Reporter Gene Bioassay in Soil Pollution Monitoring and Assessment.

A topsoil sample obtained from a highly industrialized area (Taranto, Italy) was tested on the DR-CALUX cell line and the exposed cells processed with proteomic and bioinformatics analyses. The presence of polyhalogenated compounds in the topsoil extracts was confirmed by GC-MS/MS analysis. Proteomic analysis of the cells exposed to the topsoil extracts identified 43 differential proteins.

Harnessing the Role of HDAC6 in Idiopathic Pulmonary Fibrosis: Design, Synthesis, Structural Analysis, and Biological Evaluation of Potent Inhibitors.

Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease characterized by a progressive-fibrosing phenotype. IPF has been associated with aberrant HDAC activities confirmed by our immunohistochemistry studies on HDAC6 overexpression in IPF lung tissues. We herein developed a series of novel HDAC6 inhibitors, having low inhibitory potency over HDAC1 and HDAC8, as potential pharmacological tools for IPF treatment.

Proteome Characterization of BALF Extracellular Vesicles in Idiopathic Pulmonary Fibrosis: Unveiling Undercover Molecular Pathways.

In the longtime challenge of identifying specific, easily detectable and reliable biomarkers of IPF, BALF proteomics is providing interesting new insights into its pathogenesis. To the best of our knowledge, the present study is the first shotgun proteomic investigation of EVs isolated from BALF of IPF patients. Our main aim was to characterize the proteome of the vesicular component of BALF and to explore its individual impact on the pathogenesis of IPF.

Specificity of serum amyloid A as a biomarker of idiopathic pulmonary fibrosis.

Serum amyloid A (SAA) is an apo-lipoprotein produced by the liver in response to proinflammatory cytokines. Few data are available on SAA levels in patients with idiopathic pulmonary fibrosis (IPF), the most common idiopathic form of interstitial pneumonitis (ILD). This study compared SAA concentration in IPF patients to other ILD groups to explore its potential use as a clinical biomarker.

Ceruloplasmin and oxidative stress in severe eosinophilic asthma patients treated with Mepolizumab and Benralizumab.

Introduction: Severe eosinophilic asthma has been associated with Th2 airway inflammation and elevated proinflammatory cytokines and chemokines, such as IL-5. Precision therapies have recently been shown to improve asthma symptoms with a steroid-sparing effect. Two such therapies, Benralizumab and Mepolizumab, humanized IgG antibodies directed against the IL-5 receptor and IL-5, have been approved for severe eosinophilic asthma.

Common molecular pathways targeted by nintedanib in cancer and IPF: A bioinformatic study.

Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease (ILD) sharing various genetic, molecular and cell processes with lung cancer (LC). Nintedanib, a tyrosine-kinase inhibitor, was first developed as an anticancer drug because it suppresses angiogenesis. It was then recognized as an anti-fibrotic agent and approved for the treatment of IPF.

Idiopathic Pulmonary Fibrosis Serum proteomic analysis before and after nintedanib therapy.

Idiopathic pulmonary fibrosis (IPF) is a fatal progressive disease with a median survival of 2-5 years. Nintedanib is a small tyrosine kinase inhibitor that reduces IPF progression, significantly slowing the annual decline in Forced Vital Capacity (FVC). Very little data is available on the molecular mechanisms of this treatment in IPF, despite a growing interest in the definition of IPF pathogenesis and target therapy.

Neutrophil-to-lymphocyte ratio in bronchoalveolar lavage from IPF patients: a novel prognostic biomarker?

Background: THIS is the first time that a bronchoalveolar lavage (BAL) neutrophil-to-lymphocyte ratio (NL-ratio) has been demonstrated in sarcoidosis and chronic hypersensitivity pneumonitis (cHP) than in idiopathic pulmonary fibrosis (IPF) patients.

Methods: Consecutive BAL samples from the 167 interstitial lung disease (ILD) patients were retrospectively enrolled in the study and clustered into three diagnostic categories: IPF, cHP and sarcoidosis.

Results: NL-ratio which proved higher in IPF (mean±SD, 2.

Proteomic characterization of idiopathic pulmonary fibrosis patients: stable versus acute exacerbation.

Acute exacerbations (AEs) are among the main causes of death in idiopathic pulmonary fibrosis (IPF) patients. In this study proteomic comparative analysis of bronchoalveolar lavage (BAL) fluid samples was performed in stable IPF patients versus AEs IPF group to identify AE pathogenetic mechanisms and novel potential predictive biomarkers. A functional proteomic analysis of BAL fluid samples from stable and AE-IPF patients was conducted in a population of 27 IPF patients.

Antithrombin III as predictive indicator of survival in idiopathic pulmonary fibrosis (IPF) patients treated with nintedanib: a preliminary study.

Background: Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease often managed with nintedanib, a tyrosine kinase inhibitor targeting several profibrotic pathways. Although clotting processes are involved in wound healing and repair in the lung, there are no data on the role of antithrombin III (ATIII) in IPF patients treated with nintedanib. A previous proteomic analysis of serum of IPF patients before and after 1 year of nintedanib treatment showed differential protein expression of ATIII.

BAL biomarkers' panel for differential diagnosis of interstitial lung diseases.

Bronchoalveolar lavage (BAL) is a useful procedure for differential diagnosis of interstitial lung diseases (ILDs) and for identification of granulomatous lung diseases. We investigated a panel of biomarkers from BAL fluid of ILD patients to evaluate their utility in differentiating ILDs. Bronchoscopy with BAL was performed in 100 consecutive patients with suspected ILD (41 sarcoidosis, 11 cHP and 24 other ILDs); the 24 patients negative for ILD diagnosis were included as control group.

The effect of cigarette smoking on bronchoalveolar lavage protein profiles from patients with different interstitial lung diseases.

The proteomic approach applied to the analysis of BAL gives a panorama of the complex network of proteins of different origin and function and their modifications at alveolar level. Cigarette smoking may influence BAL protein composition and it represents the most relevant risk factor for several lung diseases. This review, for the first time, discusses the available literature regarding the effects of cigarette smoking on BAL protein composition of healthy subjects and patients affected by interstitial lung diseases (ILD).

Oxidant/Antioxidant Disequilibrium in Idiopathic Pulmonary Fibrosis Pathogenesis.

Idiopathic pulmonary fibrosis is characterised by abnormal reepithelialisation and remodelling consequent to persistent stimuli or injury. The involvement of oxidative stress in alveolar injury, inflammation and fibrosis development has been suggested. Increased concentrations of lipid peroxidation products, oxidised proteins and an altered antioxidant enzyme status with the depletion of glutathione, the most abundant low-molecular-weight antioxidant, have often been reported in epithelial lining fluid of IPF patients.
