Biological Effects of Selenium‐Containing Ionic Liquids: Cytotoxicity, Mercury Interaction, and Antiproliferative Activity in Glioblastoma Cells

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Selenium (Se) is an essential micronutrient that participates in redox regulation and cellular homeostasis. Selenium‐containing ionic liquids (ILsSe) have emerged as hybrid compounds combining the properties of organoselenium molecules with the tunable features of ionic liquids.

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Effects of Tributyltin Chloride on Human Neuronal Differentiation and Mice Brain Development

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT According to the developmental origins of health and disease hypothesis, perinatal exposure to an environmental toxicant during the development of the nervous system could cause a permanent cellular modification that may promote the appearance of neurodegenerative diseases at an older age.

Diving Deeper Into Mechanisms of Acrylamide‐Induced Toxicity: RNA Sequencing Reveals Transcriptomic Alteration and Retrotransposon Expression in Drosophila melanogaster

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

open access: yesThe FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.
