Environmental pollutants-dependent molecular pathways and carcinogenesis [PDF]

BioDiscovery, 2019
Exposure to environmental pollutants can modulate many biological and molecular processes such as gene expression, gene repair mechanisms, hormone production and function and inflammation, resulting in adverse effects on human health including the ...

Role of dendritic cells in the induction of regulatory T cells [PDF]

, 2011
Dendritic cells (DCs) play a key role in initiating immune responses and maintaining immune tolerance. In addition to playing a role in thymic selection, DCs play an active role in tolerance under steady state conditions through several mechanisms which ...

Synthesis and Characterization of Ag–Fe Bimetallic Nanoparticles and Nanocomposites (Alloys and Core–Shells) for Photocatalytic Degradation of Bromophenol Blue Dye Using Grewia optiva Leaf Extract

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Ag–Fe bimetallic nanoparticles (alloy and core–shell structures) were synthesized using Grewia optiva leaf extract through a green, phytochemical‐mediated approach. The effects of pH, temperature, extract concentration, and Ag:Fe molar ratio on nanoparticle formation were systematically optimized, enabling size‐controlled and morphologically ...

Using nuclear receptor activity to stratify hepatocarcinogens. [PDF]

PLoS ONE, 2011
BackgroundNuclear receptors (NR) are a superfamily of ligand-activated transcription factors that control a range of cellular processes. Persistent stimulation of some NR is a non-genotoxic mechanism of rodent liver cancer with unclear relevance to ...

Steroid Hormones and Endocrine Disruptors: Recent Advances in Receptor–Mediated Actions [PDF]

, 2001
It has been accepted that receptor-mediated action of steroid hormones depends on both the receptor and the hormonal level. The mechanism of transcription by steroid receptors is mediated by cofactors, which function as co-activators or co-repressors,

Orchestrating the metastatic symphony: the role of extracellular vesicles in the epithelial–mesenchymal transition and pulmonary niche formation of breast cancer

Biological Reviews, EarlyView.
ABSTRACT The complexity of breast cancer (BC) lung metastasis lies in the capacity of tumour cells to interact efficiently with distant organs to promote colonisation, a process that involves the sophisticated coordination of inherent cellular plasticity and the remodelling of the distant microenvironment.

Polychlorinated naphthalenes in the serum of individuals with thyroid dysfunction and their potential mechanisms of impact on disease progression

Emerging Contaminants
Polychlorinated naphthalenes (PCNs) comprise 75 congeners, with varying concentrations and major congeners across different populations. Recent studies have found a relationship between PCNs and thyroid hormone levels, suggesting they may interfere with ...

Exposure to polybrominated diphenyl ethers (PBDEs) suppresses the release of pro-inflammatory products by alveolar macrophages in vitro [PDF]

, 2010
Endocrine disrupting chemicals have adverse effects on immune function that may result in respiratory conditions. Inhalation of dust is a major route of exposure to PBDEs; however, the impact of PBDEs on the immune response is unclear.

Structural and Biological Insights Into Copper(I) Phosphane Complexes With Boron‐Phenylated Poly(3‐(CF3)Pyrazolyl)‐ and Poly(6‐(CF3)‐2‐pyridyl)‐Borates

Chemistry – A European Journal, EarlyView.
This study reports six new copper(I) complexes with unusual coordination and strong anticancer activity against a panel of human cancer cell lines derived from different solid tumors. The most active compounds outperform cisplatin, even in resistant cells, by inhibiting protein disulfide isomerase and inducing redox stress that triggers non‐apoptotic ...

The role of the host—Neutrophil biology

Periodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...
