Chronic ethanol consumption in mice does not induce DNA damage in somatic or germ cells, evaluated by the bone marrow micronucleous assay and the dominant lethal mutation assay [PDF]

, 2012
Indexación: Web of Science; ScieloAlthough alcohol is known to be a carcinogen for humans, ethanol-genotoxicity studies are incomplete. Ethanol seems not to be a bacterial mutagen, but the results are conflicting in rodent assays.

Impact of organic pollutants on phenotype and gene expression in human breast cancer cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Human exposure to industrial chemical compounds is widespread and, although often beneficial, prolonged contact may contribute to disease development, including cancer. While many studies have shown organic pollutants (OP) are cytotoxic, few have explored how long‐term exposure alters cell phenotype.

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.

Cellular Morphometric Analysis (CellMorph)—a comprehensive imaging‐based tool for quantifying cellular phenotype heterogeneity and dynamics across biological processes

The FEBS Journal, EarlyView.
CellMorph is a groundbreaking tool that allows researchers to analyze multiple features from single cells, including cell size and shape, cytosolic staining and subcellular texture, nuclear staining, and morphometry. By evaluating images from both bright‐field and fluorescence microscopy, it also tracks changes in living cells during key processes such
