Chronic Low‐Dose Unsymmetrical Dimethylhydrazine Exposure in Rats: Multiorgan Mechanisms and Biomarker Identification

Journal of Applied Toxicology, EarlyView.
ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

Immunomodulation of the Prostate Tumor Microenvironment Following Inorganic Arsenic Exposure

Journal of Applied Toxicology, EarlyView.
ABSTRACT The tumor microenvironment (TME) influences prostate cancer (PCa) progression through stromal and immune interactions. Adipose‐derived mesenchymal stromal cells (ASCs) modulate immune tone, while inorganic arsenic (iAs), a widespread toxicant, is linked to immune suppression and carcinogenesis.

Immunomodulatory and Cytotoxic Properties of Enniatin B1 in Porcine Alveolar Macrophages

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study investigates the immunomodulatory effects of Enniatin B1 (ENNB1), an emerging mycotoxin, on porcine alveolar macrophages (PAMs), a species‐specific model relevant to human innate immunity. PAMs were exposed to increasing ENNB1 concentrations (0.5–6 μM) over 6, 24, and 48 h.

Activation of the transcription factor, nuclear factor kappa-B, during the estrous cycle and early pregnancy in the pig

Reproductive Biology and Endocrinology, 2010
Establishment and maintenance of pregnancy in the pig involves intricate communication between the developing conceptuses and the maternal endometrium. This process occurs during trophoblast elongation which is spaciotemporally associated with conceptus ...

Investigation of the Mechanism of Cinnamaldehyde in Irritable Bowel Syndrome Based via Network Pharmacology, Molecular Docking, and Animal Experiments

Pediatric Discovery, EarlyView.
Through network pharmacology and molecular docking, it has been discovered that CA can target MAOB, among other proteins, to exert a therapeutic effect in IBS. In vivo, CA lowered visceral hypersensitivity, anxiety and depression‐like behaviors, and fecal water content, highlighting its therapeutic potential for IBS via anti‐inflammatory pathways ...

Selective Antagonists of the Bronchiolar Epithelial NF-κB-Bromodomain-Containing Protein 4 Pathway in Viral-Induced Airway Inflammation

Cell Reports, 2018
Summary: The mechanisms by which the mammalian airway detects invading viral pathogens to trigger protective innate neutrophilic inflammation are incompletely understood.

Nuclear Factor-κB Dysregulation and α-Synuclein Pathology: Critical Interplay in the Pathogenesis of Parkinson’s Disease

Frontiers in Aging Neuroscience, 2020
The loss of dopaminergic neurons of the nigrostriatal system underlies the onset of the typical motor symptoms of Parkinson’s disease (PD). Lewy bodies (LB) and Lewy neurites (LN), proteinaceous inclusions mainly composed of insoluble α-synuclein (α-syn)

HTLV‐1 Tax Reshapes the DNA‐Binding Pattern of Transcription Factor IRF4 and Disrupts Host Gene Regulation

Cancer Science, EarlyView.
Proteomic mapping of Tax complexes in HTLV‐1–infected T‐cells identified IRF4 as a Tax interactor. Chromatin profiling showed Tax reprograms IRF4 occupancy with H3K27ac gains at super‐enhancers; Tax–IRF4 co‐expression altered chromatin accessibility and transcription, and ATL‐associated IRF4 mutants partially phenocopied these changes. ABSTRACT Human T‐

Newly identified properties of known pharmaceuticals and myxobacterial small molecules revealed by screening for autophagy modulators

The FEBS Journal, EarlyView.
Autophagy is a cellular degradation process involved in, for example, immune responses to pathogens and neurodegeneration. To identify modulators of autophagy, we developed a microscopy‐based screening assay and identified previously unknown autophagy‐modulating activities in known drugs and natural products from myxobacteria and fungi.

NF-κB RelA regulates temporal oligodendrocyte differentiation in the postnatal brains

Frontiers in Cellular Neuroscience
The NF-κB signaling pathway responds to a diverse range of cytokines and extracellular stresses, regulating immune responses, inflammation, cell proliferation, and cell death.
