Alternative Developmental Toxicity Screening Methods Using Chick Embryo‐Based Models
ABSTRACT Nonclinical developmental toxicity studies are used to investigate the potential toxicities of drugs and chemical candidates on normal embryonic and fetal development during pregnancy, generally using mammalian laboratory animals such as rats and rabbits.

Identification of putative noncoding RNAs among the RIKEN mouse full-length cDNA collection [PDF]
With the sequencing and annotation of genomes and transcriptomes of several eukaryotes, the importance of noncoding RNA (ncRNA)-RNA molecules that are not translated to protein products-has become more evident. A subclass of ncRNA transcripts are encoded

ABSTRACT Endocrine‐disrupting chemicals (EDCs), such as 17α‐ethinylestradiol (EE2), have raised concerns about their potential effects on aquatic organisms, particularly during early developmental stages. In this context, the study of behavioral disruption has gained considerable attention, as it may have consequences on individual fitness and ...

On the development of the chondrocranium and the histological anatomy of the head in perinatal stages of marsupial mammals [PDF]
An overview of the literature on the chondrocranium of marsupial mammals reveals a relative conservatism in shape and structures. We document the histological cranial anatomy of individuals representing Monodelphis domestica, Dromiciops gliroides ...

KU80 suppresses endonuclease G activity to preserve genomic integrity
Under normal conditions, EndoG remains restricted to mitochondria and the genome remains intact. When KU80 is absent, EndoG translocates into the nucleus, where it promotes DNA fragmentation and genomic instability. Thus, this work highlights the importance of KU80 in tightly controlling EndoG localization to preserve genome stability.

Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?
ABSTRACT The enteric nervous system (ENS), a key component of the gut–brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)—a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or ...

Histone Density and Dynamics Shape Mitotic Chromatid Architecture in Xenopus Egg Extracts
Histone chaperones and chromatin remodelers modulate histone density and dynamics. The resulting local chromatin properties are integrated with DNA reconfiguration activities mediated by condensins and topoisomerase IIα to shape the global architecture of mitotic chromosomes.

Dopaminergic neurons are particularly susceptible to ferroptosis. Pacemaking activity–driven calcium (Ca2+) influx increases metabolic demand and reactive oxygen species (ROS) production, promoting iron release from aconitase. Alpha‐synuclein (α‐syn) enhances iron uptake via transferrin receptor 1 (TfR1) and exhibits ferrireductase activity, converting

Atg5 and Ambra1 differentially modulate neurogenesis in neural stem cells [PDF]
Neuroepithelial cells undergoing differentiation efficiently remodel their cytoskeleton and shape in an energy-consuming process. The capacity of autophagy to recycle cellular components and provide energy could fulfill these requirements, thus ...
