Polystyrene nanoparticles affect development and induce genotoxicity in Drosophila melanogaster

It is estimated that more than 170 trillion plastic particles float in the World’s oceans, making plastic pollution one of the most important environmental and health emergencies.

MUC1 as a Survival Effector of Radiotherapy‐Induced Epithelial Hybrid States in Basal‐Like Breast Cancer

International Journal of Cancer, EarlyView.
Basal‐like breast cancer (BLBC) is aggressive and often exhibits inherent or acquired resistance to radiotherapy (RT), a primary treatment option. RT resistance is underpinned by molecular alterations, many of which are poorly understood. Here, RT‐induced transcriptomic changes were analyzed using bulk and spatial sequencing in a BLBC mouse model and ...

Lymphocyte Micronucleus Formation Is Driven by Inflammation‐Induced Oxidative DNA Damage in Oesophageal Cancer Development

International Journal of Cancer, EarlyView.
Chromosomal instability is a hallmark of cancer, but minimally invasive ways to detect systemic DNA damage and cancer risk remain limited. Here, using patient blood samples, the authors investigated lymphocyte micronuclei (MN) frequency as a potential marker of DNA damage across the progression from gastroesophageal reflux disease to Barrett's ...

Rising Incidence and Mortality of Colorectal Cancer Among Younger Adults: A Population‐Based Study in Taiwan, 1994–2018

International Journal of Cancer, EarlyView.
Colorectal cancer incidence and mortality have increased in the Asia‐Pacific region over the past three decades. This population‐based study in Taiwan suggests a shift of the colorectal cancer burden towards the younger generations. An age–period–cohort model revealed higher annual increases in incidence (3.58%) and mortality (1.0%) rates among ...

FAM107A loss facilitates TTK‐OPTN‐mediated mitophagy to drive docetaxel resistance in castration‐resistant prostate cancer

Interdisciplinary Medicine, EarlyView.
In the progression of docetaxel resistance, downregulation of FAM107A releases its transcriptional repression of TTK, leading to TTK upregulation. TTK enhances the interaction and phosphorylation of OPTN. This activates mitophagy in tumor cells, facilitates clearance of damaged mitochondria, reduces intracellular reactive oxygen species accumulation ...

New Approach Methodologies (NAMs) in Alternative Methods: A Comparative Cytotoxicity Analysis of Nanostructured Hydroxyapatite in Adipose Stem Cells Spheroids

Journal of Applied Toxicology, EarlyView.
ABSTRACT Toxicological assessment is essential in NP approval for health and medical applications. Although 2D cell culture has been widely used, 3D models, especially spheroids, provide better predictive value for toxicological risk assessments since they replicate complex cellular interactions more accurately.

Miniaturized Droplet‐Based Adaptation of the Ames Test for High‐Throughput Mutagenicity Assessment

Journal of Applied Toxicology, EarlyView.
ABSTRACT This work presents the first demonstration of a tube‐based droplet microfluidic implementation of the Ames test, bridging single‐droplet resolution with regulatory genotoxicity testing. The Ames test is a cornerstone assay for detecting mutagenicity, but conventional plate‐ and well‐based formats suffer from high reagent consumption, low ...

Impact of Methylparaben on Cumulus Cell DNA Integrity and Porcine Oocyte Developmental Competence In Vitro

Journal of Applied Toxicology, EarlyView.
ABSTRACT Parabens (PBs) are compounds widely used as preservatives in personal care products, food, and pharmaceuticals. Methylparaben (MePB) is the most used by different industries due to its chemical properties and low cost. The high daily human exposure to these compounds has raised concerns about their potential effects on health, particularly on ...
