Evolution and diversity of transposable elements in fish genomes

Scientific Reports, 2019
Transposable elements (TEs) are genomic sequences that can move, multiply, and often form sizable fractions of vertebrate genomes. Fish belong to a unique group of vertebrates, since their karyotypes and genome sizes are more diverse and complex, with ...

Human Atlas of Tooth Decay Progression: Identification of Cellular Mechanisms Driving the Switch from Dental Pulp Repair Toward Irreversible Pulpitis

Advanced Science, EarlyView.
Tooth decay progression transforms the dental pulp response from repair to fibrosis. At early stages, stromal cells reprogram to repair the extra cellular matrix (ECM), blood vessels, and nerves, remodel and grow, keeping repair possible. In advanced decay, hypoxia, and vessel regression, in complement with an immune switch, fuel nerve degeneration and

Function and evolution of local repeats in the Firre locus

Nature Communications, 2016
Mammalian genomes contain multiple repetitive sequences such as transposable elements and local repeats. Here, the authors show that the conserved long non-coding RNA Firre contains repeats that act as nuclear retention signals and a DNA enhancer element.

The genomic ecosystem of transposable elements in maize

bioRxiv, 2019
Transposable elements (TEs) constitute the majority of flowering plant DNA, reflecting their tremendous success in subverting, avoiding, and surviving the defenses of their host genomes to ensure their selfish replication.

Ubc9‐Mediated SUMOylation of RPL3, an Unappreciated Mechanism against Hepatocyte Senescence by Repressing the DHX9‐p16 Axis

Advanced Science, EarlyView.
Liver aging is characterized by a decline in the expression of the SUMO‐conjugating enzyme Ubc9, resulting in reduced SUMOylation levels in hepatocytes, particularly in the case of ribosomal protein RPL3. Disruption of RPL3 SUMOylation increases its nuclear translocation. Interestingly, ribosome‐free RPL3 facilitates the recruitment of helicase DHX9 to

Structural and sequence diversity of eukaryotic transposable elements.

Genes & Genetic Systems, 2019
The majority of eukaryotic genomes contain a large fraction of repetitive sequences that primarily originate from transpositional bursts of transposable elements (TEs).

Temporal Stretch‐Induced Nuclear Mechanosensing Coordinates Early Chromatin Accessibility and Genome Protection

Advanced Science, EarlyView.
Cyclic stretching of fibroblasts triggers coordinated nuclear mechanosensing events, including calcium ion release, perinuclear actin assembly, emerin translocation, and H3K9me3 loss, increasing chromatin accessibility for specific genes related to mechanotransduction and repair.

Lactylation Enhances the Activity of Lactate Dehydrogenase A and Promotes the Chemoresistance to Cisplatin Through Facilitating DNA Nonhomologous End Junction in Lung Adenocarcinoma

Advanced Science, EarlyView.
Lactylation, linked to glycolysis, is poorly understood in regulation. It is found that LDHA is lactylated at Lys81/Lys318 by AARS1, boosting its activity and cellular lactylation via positive feedback in LUAD. Lactylation regulates NHEJ‐related proteins; their delactylation impairs NHEJ and increases cisplatin sensitivity, offering anticancer insights.
