Transposable elements drive widespread expression of oncogenes in human cancers

Nature Genetics, 2019
Transposable elements (TEs) are an abundant and rich genetic resource of regulatory sequences1–3. Cryptic regulatory elements within TEs can be epigenetically reactivated in cancer to influence oncogenesis in a process termed onco-exaptation4.

Neutrophil Extracellular Trap Reprograms Cancer Metabolism to Form a Metastatic Niche Promoting Non‐Small Cell Lung Cancer Brain Metastasis

Advanced Science, EarlyView.
This study mainly combines spatial/single‐cell transcriptomics and metabolomics to reveal LOX+ Malig‐5 as NSCLC brain metastasis‐initiating cells, forming a niche with NET‐releasing neutrophils via the NET‐KRT10 axis. The metastatic niche is involved with metabolic reprogramming, with palmitic acid serving as a key metabolite.

U‐Shaped Response of Flowering Time to Low and High Nitrogen via a Transcription Feedback Loop in Rice

Advanced Science, EarlyView.
The “seesaw effect” of Nhd1‐Ghd7 module in regulating flowering time (days to heading in rice) responses to nitrogen (N) via Hd3a/RFT1: deficient‐N (DN) delays flowering via Ghd7‐mediated suppression of Nhd1; moderate‐N (MN) impairs this suppression, enhancing Nhd1 to promote flowering; whereas superior‐N (SN) delays flowering by Nhd1‐activated ...

Cross-Regulation between Transposable Elements and Host DNA Replication [PDF]

Viruses, 2017
Transposable elements subvert host cellular functions to ensure their survival. Their interaction with the host DNA replication machinery indicates that selective pressures lead them to develop ancestral and convergent evolutionary adaptations aimed at conserved features of this fundamental process.

Mesenchymal Stem Cell‐Derived Extracellular Vesicles Modulate the Course of Peritoneal Inflammation Through Metabolic and Epigenetic Regulation

Advanced Science, EarlyView.
MSC‐EVs alleviate peritoneal inflammation and fibrogenesis by disrupting the H3K18la‐CCL2 axis and crosstalk between mesothelial cells and Ly6c2⁺ macrophages. Model cartoons are constructed using the Biorender website (https://www.biorender.com/), and a usage license is obtained. Abstract Peritoneal dialysis (PD), as a renal replacement therapy, relies

Activity and Silencing of Transposable Elements in C. elegans

DNA
Since the discovery of transposable elements (TEs) in maize in the 1940s by Barbara McClintock transposable elements have been described as junk, as selfish elements with no benefit to the host, and more recently as major determinants of genome structure

Human transposable elements in Repbase: genomic footprints from fish to humans

Mobile DNA, 2018
Repbase is a comprehensive database of eukaryotic transposable elements (TEs) and repeat sequences, containing over 1300 human repeat sequences. Recent analyses of these repeat sequences have accumulated evidences for their contribution to human ...

Enhancer activation from transposable elements in extrachromosomal DNA

Nature Cell Biology
Abstract Extrachromosomal DNA (ecDNA) drives oncogene amplification and intratumoral heterogeneity in aggressive cancers. While transposable element (TE) reactivation is common in cancer, its role on ecDNA remains unexplored. Here, we map the 3D architecture of MYC-amplified ecDNA in colorectal cancer cells and identify 68 ecDNA-interacting

Geometrically Encoded Positioning of Introns, Intergenic Segments, and Exons in the Human Genome

Advanced Science, EarlyView.
This study introduces a new hypothesis: exons, introns, and intergenic segments are non‐random projections of the functional layers of 3D structure of chromatin packing domains. Evidence is presented that this “geometric code” may encode volumetric structure, reconciling epigenetic patterns, correlates with oncogenic mutations, acting as a potential ...
