Endometrial Stromal Cell Senescence: A Non‐Negligible Factor in Recurrent Pregnancy Loss

iMetaMed, EarlyView.
As populations age, links between female reproductive aging and infertility are increasingly evident. Cellular senescence, characterized by near‐irreversible cell‐cycle arrest and accumulation of damage, can impair tissue function. In the endometrium, aberrant senescence of endometrial stromal cells (EnSCs) may compromise receptivity, hinder embryo ...

Pathogen Response Genes Mediate Caenorhabditis elegans Innate Immunity

, 2012
Innate immunity is crucial in the response and defense against pathogens for invertebrates and vertebrates alike. The soil nematode Caenorhabditis elegans is a useful model to study the eukaryotic innate immune response to microbial pathogenesis.

Weizmannia coagulans XY2 Mitigates Copper Neurotoxicity via Gut–Brain Axis Modulation of Tryptophan Metabolism and Oxidative‐Inflammatory Crosstalk

iMetaOmics, EarlyView.
Copper interferes with tryptophan metabolism and 5‐HT levels by modulating intestinal flora. Intestinal barrier breakdown and inflammatory response trigger nerve damage under copper exposure. W. coagulans XY2 alleviates copper‐induced neurotoxicity by targeting a multi‐dimensional “tryptophan metabolism‐antioxidant defense‐gut‐brain axis” network.

Move beyond free radical theory of aging

iMetaOmics, EarlyView.
Free radicals play a dual, dose‐dependent role in aging. Low levels activate the key sensor adenosine 5'‐monophosphate‐activated protein kinase (AMPK), promoting cell survival mechanisms like autophagy and enhancing mitochondrial health. High levels, however, push AMPK to initiate cell death pathways, such as apoptosis. This positions AMPK as a central

LIN‐24 as a Molecular Switch: Dual Cytotoxic and Cytoprotective Roles of an Aerolysin‐Like Protein in C. elegans

Journal of Applied Toxicology, EarlyView.
ABSTRACT LIN‐24, an aerolysin‐like pore‐forming protein in Caenorhabditis elegans, exemplifies how ancient cytolytic mechanisms have evolved into regulated cellular processes. Initially identified for inducing nonapoptotic, engulfment‐dependent cell death in vulval precursor cells, LIN‐24 has emerged as a multifunctional regulator of metabolism, stress

Reduced Proteasome Degradation of HSF-1 Shifts Protein Stress Management With Age in Caenorhabditis elegans. [PDF]

Aging Cell
Ageing C. elegans prioritises chronic protein stress protection over acute stress response by coordinating HSF‐1 activity. Decreased PBS‐7 binding in aged worms reduces HSF‐1 degradation, enhancing its ability to upregulate protective factors against accumulating protein aggregates while simultaneously suppressing its activation under acute heat shock.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...
