Nephronectin (NPNT) is a Crucial Determinant of Idiopathic Pulmonary Fibrosis: Modulating Cellular Senescence via the ITGA3/YAP1 Signaling Axis

Advanced Science, EarlyView.
Through a comprehensive multi‐omics analysis, this study identifies a marked reduction in Nephronectin (NPNT) expression within fibrotic lung tissue. This reduction impairs the binding capability to the ITGA3 receptor, consequently causing YAP1 to persist in the cytoplasm, where it undergoes degradation.

Kinsenoside‐Loaded Microneedle Accelerates Diabetic Wound Healing by Reprogramming Macrophage Metabolism via Inhibiting IRE1α/XBP1 Signaling Axis

Advanced Science, EarlyView.
Gut metabolite trimethylamine N‐oxide accumulates in the diabetic wound area to amplify macrophage inflammation via enhancing glycolysis activities. Kinsenoside induces macrophage repolarization from M1 to M2 phenotype through inhibiting IRE1α/XBP1 pathway, followed by HIF‐1α‐glycolysis axis repression and mitophagy‐oxidative phosphorylation axis ...

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 ...

Amino Acid‐Sensing Neurons in the Anterior Piriform Cortex Control Brown Adipose Tissue Thermogenesis

Advanced Science, EarlyView.
This study identifies a class of amino acid‐sensing neurons, APCCRH neurons, which regulate BAT thermogenesis. Leucine deficiency alters intrinsic excitability through GCN2 signaling pathway, activating APCCRH neurons, which in turn regulate BAT thermogenesis via projections to the lateral hypothalamus.

Geminiviruses and RNA silencing

Trends in Plant Science, 2005
Geminiviruses are single-stranded circular DNA viruses that cause economically significant diseases in a wide range of crop plants worldwide. In plants, post-transcriptional gene silencing (PTGS) acts as a natural anti-viral defense system and plays a role in genome maintenance and development.

The Genetics of RNA Silencing

Annual Review of Genetics, 2002
▪ Abstract  Although initially recognized as a handy tool to reduce gene expression, RNA silencing, triggered by double-stranded RNA molecules, is now recognized as a mechanism for cellular protection and cleansing: It defends the genome against molecular parasites such as viruses and transposons, while removing abundant but aberrant nonfunctional ...

RNA silencing

Current Opinion in Biotechnology, 2000
Gene silencing through the increased degradation of mRNA appears to represent a novel cellular pathway that is functional in a broad range of organisms. Recent work has established a role for RNA silencing in host antiviral defense and transposon silencing, suggesting a potential application in plant functional genomics.

RNA-dependent RNA polymerases in RNA silencing

Biological Chemistry, 2011
Abstract RNA-dependent RNA polymerases (RdRPs) synthesize double-stranded RNAs that are processed into small RNAs and mediate gene silencing. Viral RdRPs and cellular RdRPs show little structural homology to each other. Cellular RdRPs play key roles in RNA silencing by producing complementary strands for target RNAs via Dicer-dependent and -

RNA-mediated gene silencing

Cellular and Molecular Life Sciences, 2003
A number of gene-silencing phenomena including co-suppression discovered in plants, quelling in fungi and RNA interference in animals have been revealed to have steps in common. All occur in the cytoplasm at a post-transcriptional level with the mRNAs of target genes degraded in a sequence-specific manner. Small non-coding RNA molecules demonstrated to
