RNA activation in insects: From emerging evidence to molecular applications

Insect Molecular Biology, EarlyView.
Canonical RNA activation involves small RNAs interacting with promoter sequences, but there is also evidence of non‐canonical RNAa in eukaryotes. Emerging evidence suggests the presence of RNAa in insects. RNAa can be utilised as a tool for functional genomic studies in insects.

Advances in high‐resolution cryo‐volume electron microscopy (cvEM) imaging for unicellular and multicellular organisms

Journal of Microscopy, EarlyView.
Abstract Cryo‐Focused Ion Beam Scanning Electron Microscopy (cryoFIB‐SEM) using samples fixed by high‐pressure freezing uniquely enables high‐resolution cryo‐volume Electron Microscope (cvEM) images of cell ultrastructure to be obtained from whole cells and complex tissues in their near native state. As the freezing process also preserves fluorescence,

Understanding extracellular vesicles in antiaging

Periodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Redox‐regulated signalling of adaptations to contractile activity in skeletal muscle: Implications for age‐related muscle weakness

Experimental Physiology, EarlyView.
Abstract Skeletal muscle adaptation to contractile activity is modulated by redox signalling, primarily through reactive oxygen species (ROS) such as hydrogen peroxide (H2O2). Early research framed ROS as deleterious byproducts of exercise, but subsequent studies have established their roles as signalling molecules involved in mitochondrial biogenesis,

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities

The Journal of Physiology, EarlyView.
Abstract figure legend Hypoxia and hypercapnia cause overlapping skeletal muscle phenotypes, including atrophy, change in myofibre metabolic profile and myogenic response to injury. Both signals operate via distinct cellular pathways. Abstract Skeletal muscle dysfunction is strongly associated with elevated mortality in acute and chronic pulmonary ...

Prohibitin Homology Domain Proteins in Caenorhabditis elegans

, 2010
The PHB-d protein family is an evolutionarily ancient family of integral membrane proteins with members in all taxa that are involved in a wide variety of biological process but share several common molecular properties: oligomerization, detergent resistant membrane (DRM) association, and regulation of other proteins.

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

ACE-inhibitory peptide Leu-Tyr-Ala in skeletal muscle actin exhibits anti-aging effects through the inhibition of acn-1 in Caenorhabditis elegans. [PDF]

J Sci Food Agric
Abstract BACKGROUND Inhibitors of angiotensin‐converting enzyme (ACE) are used in pharmaceuticals and functional foods. Captopril, a well‐known ACE inhibitor, extends the lifespan of the nematode Caenorhabditis elegans. Bioactive peptides derived from food sources are considered safe ACE inhibitors.

Preeclampsia‐derived small extracellular vesicles disrupt blood–brain barrier integrity and activate glial cells in vitro

The Journal of Physiology, EarlyView.
Abstract figure legend This study assessed the impact of plasma‐derived small extracellular vesicles (sEVs) from healthy pregnant women and those diagnosed with late‐onset preeclampsia (PE) on the blood–brain barrier (BBB) integrity and glial cell response. PE patients had higher sEV concentrations than healthy controls.
