Attenuated Nuclear Tension Regulates Progerin‐Induced Mechanosensitive Nuclear Wrinkling and Chromatin Remodeling

Advanced Science, EarlyView.
The premature aging‐related progerin leads to defective nuclear morphology and is associated with disrupted molecular coupling between the extranuclear cytoskeleton and lamin‐associated nuclear envelope. It is discovered that progerin expression reduces nuclear tension, forms nuclear wrinkling, and enhances chromatin dynamics, thereby regulating ...

Randomized Self Organizing Map [PDF]

arXiv, 2020
We propose a variation of the self organizing map algorithm by considering the random placement of neurons on a two-dimensional manifold, following a blue noise distribution from which various topologies can be derived. These topologies possess random (but controllable) discontinuities that allow for a more flexible self-organization, especially with ...

A single heterochronic blood exchange reveals rapid inhibition of multiple tissues by old blood. [PDF]

, 2016
Heterochronic parabiosis rejuvenates the performance of old tissue stem cells at some expense to the young, but whether this is through shared circulation or shared organs is unclear.

The Dynamic Landscape of 3′‐UTR Alternative Polyadenylation Across Mouse Fetal Development and Anatomy

Advanced Science, EarlyView.
This work maps 3′‐UTR APA across mouse fetal development and tissues, identifying conserved sequence determinants that influence pAS choice. In fetal brain tissues, complex APA dynamics during development are potentially regulated by RBPs like Rbm38, which restrict distal pAS usage.

Astrocyte-secreted GDNF and glutathione antioxidant system protect neurons against 6OHDA cytotoxicity

Neurobiology of Disease, 2009
In recent years, GDNF has emerged as a protective and restorative agent in several models of neurodegeneration; however, the exact molecular mechanisms responsible for these effects are not yet fully understood. Here we examined the effects of astrocytes

Neuronal FGF13 Inhibits Mitochondria‐Derived Damage Signals to Prevent Neuroinflammation and Neurodegeneration in a Mouse Model of Parkinson's Disease

Advanced Science, EarlyView.
This study elucidates a novel role of FGF13 in manipulating neuronal fate via mitochondrial transfer. FGF13 is identified as a mitochondria‐stabilizing protein by interacting with mitochondrial proteins. Under stress, the decrease of neuronal FGF13 fails to retain mitochondria within the cytoplasm, leading to the release of damaged mitochondria to ...

Beyond amyloid and tau: rethinking Alzheimer’s disease through less explored avenues

Open Biology
Neurodegenerative diseases, particularly Alzheimer’s disease (AD), pose a significant challenge in ageing populations. Our current understanding indicates that the onset of toxic amyloid and tau protein pathologies initiates disease progression. However,

A novel long non-coding natural antisense RNA is a negative regulator of Nos1 gene expression [PDF]

, 2015
Long non-coding natural antisense transcripts (NATs) are widespread in eukaryotic species. Although recent studies indicate that long NATs are engaged in the regulation of gene expression, the precise functional roles of the vast majority of them are ...

Wireless In Situ Catalytic Electron Signaling‐Mediated Transcriptomic Reprogramming for Neuron Regeneration via Adaptable Antennas

Advanced Science, EarlyView.
A wireless‐charging sustained oxygen release from conductive microgels (SOCO) served as an antenna and an on‐demand O2 release for nerve regeneration is developed. Introducing “electromagnetic messenger”, using external alternating magnetic field (AMF) to enhance catalytic oxygen release and electrical stimulation to promote the reconstruction of blood

Bradykinin/bradykinin 1 receptor promotes brain microvascular endothelial cell permeability and proinflammatory cytokine release by downregulating Wnt3a

Journal of Biochemical and Molecular Toxicology, Volume 36, Issue 12, December 2022., 2022
Abstract Stroke is a life‐threatening disease with limited therapeutic options. Damage to the blood–brain barrier (BBB) is the key pathological feature of ischemic stroke. This study explored the role of the bradykinin (BK)/bradykinin 1 receptor (B1R) and its mechanism of action in the BBB.
