A common secretomic signature across epithelial cancers metastatic to the pleura supports IL-6 axis therapeutic targeting.

Background: Many cancers metastasize to the pleura, resulting in effusions that cause dyspnea and discomfort. Regardless of the tissue of origin, pleural malignancies are aggressive and uniformly fatal, with no treatment shown to prolong life. The pleural mesothelial monolayer is joined by tight junctions forming a contained bioreactor-like space, concentrating cytokines and chemokines secreted by the mesothelium, tumor, and infiltrating immune cells.

RETRO-POPE: A Retrospective, Multicenter, Real-World Study of All-Cause Mortality in COPD.

Purpose: The Phenotypes of COPD in Central and Eastern Europe (POPE) study assessed the prevalence and clinical characteristics of four clinical COPD phenotypes, but not mortality. This retrospective analysis of the POPE study (RETRO-POPE) investigated the relationship between all-cause mortality and patient characteristics using two grouping methods: clinical phenotyping (as in POPE) and Burgel clustering, to better identify high-risk patients.

Patients And Methods: The two largest POPE study patient cohorts (Czech Republic and Serbia) were categorized into one of four clinical phenotypes (acute exacerbators [with/without chronic bronchitis], non-exacerbators, asthma-COPD overlap), and one of five Burgel clusters based on comorbidities, lung function, age, body mass index (BMI) and dyspnea (very severe comorbid, very severe respiratory, moderate-to-severe respiratory, moderate-to-severe comorbid/obese, and mild respiratory).

Extract Tunes the Cellular Response to Stress by Modulating DNA Damage, Redox Components, and Gene Expression.

Ionizing radiation (IR) and reactive oxygen species (ROS)-induced oxidative stress can cause damage to cellular biomolecules, including DNA, proteins, and lipids. These harmful effects can compromise essential cellular functions and significantly raise the risk of metabolic dysfunction, accumulation of harmful mutations, genome instability, cancer, accelerated cellular senescence, and even death. Here, we present an investigation of HeLa cancer cells' early response to gamma IR (γ-IR) and oxidative stress after preincubation of the cells with natural extracts of the resurrection plant .

Differential influence of basic psychological needs on burnout and academic achievement in three southeast European countries.

Several studies show the importance of basic psychological needs (BPN) for decreasing burnout and increasing grade point average (GPA), but, to our knowledge, no prior study has explored the potential contextual differences in Southeastern European countries. Moreover, even less is known about how this relationship may differ during stressful (exam) and less stressful (beginning of the semester) periods. Measures of the Maslach Burnout Inventory-Student Survey and BPN Satisfaction and Frustration Scale were translated and adapted.

Early Cell Cultures from Prostate Cancer Tissue Express Tissue Specific Epithelial and Cancer Markers.

Prostate cancer (PCa) is a widespread oncological disease that proceeds in the indolent form in most patients. However, in some cases, the indolent form can transform into aggressive metastatic incurable cancer. The most important task of PCa diagnostics is to search for early markers that can be used for predicting the transition of indolent cancer into its aggressive form.

Effects of thermal treatments on the hydrophobicity and anticorrosion properties of as-grown graphene coatings.

Graphene grown on metal substrates has been reported to provide efficient and robust hydrophobicity during water vapor condensation on metal surfaces. However, due to the intrinsic negative coefficient of thermal expansion (CTE) of graphene, the potential thermal stress in real application environments can cause CTE mismatch and then damage the protective graphene coatings, leading to loss of surface hydrophobicity and anticorrosion properties. In this study, the effect of thermal treatments on anticorrosion properties and subsequent hydrophobicity of the graphene surface has been investigated.

Transient expression of inactive RB in mesenchymal stem cells impairs their adipogenic potential and is associated with hypermethylation of the PPARγ2 promoter.

The retinoblastoma gene product (pRb) is a chromatin-associated protein that can either suppress or promote activity of key regulators of tissue-specific differentiation. We found that twelve weeks after transfection of the exogenous active (ΔB/X and Δр34) or inactive (ΔS/N) forms of RB into the 10T1/2 mesenchymal stem cells and clonal selection not a single cell line did contain exogenous RB, despite being G-418 resistant. However, the consequences of the transient production of exogenous RB had different effects on the cell fate.

p130 And pRb in the Maintenance of Transient Quiescence of Mesenchymal Stem Cells.

An effective regulation of quiescence plays a key role in the differentiation, plasticity, and prevention of stem cells from becoming malignant. The state of quiescence is being controlled by the pRb family proteins which show overlapping functions in cell cycle regulation; however, their roles in controlling the proliferation of mesenchymal stem cells (MSCs) remain to be understood. This study investigated the regulation of transient quiescence using growth curves, proliferation assay, the cytometric evaluation of cell cycle, Western blotting, and the electromobility gel shift assay (EMSA) on synchronized MSCs of the C3H10Т1/2 and control cells with different statuses of pRb proteins.

Preparation and characterization of the antibody recognizing AMACR inside its catalytic center.

Alpha-methylacyl-CoA racemase (AMACR) catalyzes the β-oxidation of fatty acids and is overexpressed in carcinomas in various organs, while its inactivation results in the inhibition of cancer growth. In the present study, we prepared and characterized 20 different mouse monoclonal antibodies against human AMACR. In the course of biopanning of a phage peptide commercial library against in-house prepared 6H9 and 2A5, and commercial 13H4 antibodies, 10 phage mimotopes recognized by each type of the antibody were selected.

New Method to Synthesize Highly Active and Durable Chemically Ordered fct-PtCo Cathode Catalyst for PEMFCs.

In the bottom-up synthesis strategy performed in this study, the Co-catalyzed pyrolysis of chelate-complex and activated carbon black at high temperatures triggers the graphitization reaction which introduces Co particles in the N-doped graphitic carbon matrix and immobilizes N-modified active sites for the oxygen reduction reaction (ORR) on the carbon surface. In this study, the Co particles encapsulated within the N-doped graphitic carbon shell diffuse up to the Pt surface under the polymer protective layer and forms a chemically ordered face-centered tetragonal (fct) Pt-Co catalyst PtCo/CCCS catalyst as evidenced by structural and compositional studies. The fct-structured PtCo/CCCS at low-Pt loading (0.

[Basal-luminal epithelial cell differentiation in prostate cancer is associated with epithelial-mesenchymal transition and epithelium migration in the mesenchyme].

Aim: In patients with prostate cancer to trace the pathway of the malignant cells of the basal layer of the prostate epithelium during their differentiation into luminal cells and/or migration in the mesenchyme.

Materials And Methods: We used histological and immunohistochemical staining of the markers of the basal layer of the prostate: cytokeratin 5 (CK5), E-cadherin and AMACR, and Western blot to assess the production of the same markers in epithelial and stromal compartments of malignant and normal prostate tissue in patients with prostate cancer.

Results: Our findings revealed that prostate cancer is associated with losing of the basal epithelial layer in the prostate tumor tissue, which is accompanied by a complete loss of CK5 secretion, increased levels of E-cadherin and AMACR in luminal epithelium and the emergence of cells producing E-cadherin and AMACR in the stromal compartment of the prostate.

[PRODUCT OF THE BMI1--A KEY COMPONENT OF POLYCOMB--POSITIVELY REGULATES ADIPOCYTE DIFFERENTIATION OF MOUSE MESENCHYMAL STEM CELLS].

Bmil is a key component of Polycomb (PcG), which in mammals controls the basic functions of mammalian somatic stem cells (SSC) such as self-renewal and differentiation. Bmi1 supports SSC via transcriptional suppression of genes associated with cell cycle and differentiation. The most studied target genes of Bmi1 are the genes of Ink4 locus, CdkI p16(Ink4a) and p1(Arf), suppression of which due to activating mutations of the BMI1 results in formation of cancer stem cells (CSC) and carcinomas in various tissues.

The quasimonochromatic ν[over ¯]_{μ} beam, produced with a peak energy of 0.6 GeV at J-PARC, is observed at the far detector Super-Kamiokande, 295 km away, where the ν[over ¯]_{μ} survival probability is expected to be minimal.

MARKERS OF THE PROSTATE BASAL LAYER CELLS ARE EFFECTIVE INDICATORS OF ITS MALIGNANT TRANSFORMATION.

Development of local or general forms of prostate cancer (PC) depends on formation of metastasis the biological nature of which is based on epithelial mesenchymal transition (EMT). ÅÌÒ presents highly conservative reversible program that is maintained by specific transcription factors which suppress E-cadherin expression and support production of mesenchymal polarity factors. The goal of this work was to study the functionally distinct markers in malignant prostate tissue of patients with prostate cancer using the histological evaluation, reverse polymerase chain reaction and immunobloting.

Experimental Model to Study the Role of Retinoblastoma Gene Product (pRb) for Determination of Adipocyte Differentiation.

Using stable constitutive expression of retinoblastoma gene product (pRb) in polypotent mesenchymal 10T1/2 cells we obtained stable cell lines hyperexpressing functionally active or inactive mutant pRb. The cells producing active exogenous pRb demonstrated high sensitivity to adipocyte differentiation inductors, whereas production of inactive form of the exogenous protein suppressed adipocyte differentiation. The obtained lines can serve as the experimental model for studying the role of pRb in determination of adipocyte differentiation.

pRb-E2F signaling in life of mesenchymal stem cells: Cell cycle, cell fate, and cell differentiation.

Mesenchymal stem cells (MSCs) are multipotent cells that can differentiate into various mesodermal lines forming fat, muscle, bone, and other lineages of connective tissue. MSCs possess plasticity and under special metabolic conditions may transform into cells of unusual phenotypes originating from ecto- and endoderm. After transplantation, MSCs release the humoral factors promoting regeneration of the damaged tissue.

Study of Wnt2 secreted by A-549 cells in paracrine activation of β-catenin in co-cultured mesenchymal stem cells.

The canonical Wnt signal pathway is a key regulator of self-renewal and cell fate determination in various types of stem cells. The total pool of β-catenin consists of two different forms: the signaling form of the protein transmits the Wnt signals from the cell membrane to the target genes, whereas the membrane β-catenin is involved in formation of cell-to-cell contact at cadherin junctions. Earlier we developed an in vitro model of epithelial differentiation of mesenchymal stem cells (MSCs) co-cultured with epithelial A-549 cells.
