The landscape of transposable elements and satellite DNAs in the genome of a dioecious plant spinach (Spinacia oleracea L.)

Mobile DNA, 2019
Repetitive sequences, including transposable elements (TEs) and satellite DNAs, occupy a considerable portion of plant genomes. Analysis of the repeat fraction benefits the understanding of genome structure and evolution.

A Two‐Protein Chemoreceptor Complex Regulates Oxygen Thresholds in Bacterial Magneto‐Aerotaxis

Advanced Science, EarlyView.
Magnetotactic bacteria align with Earth's magnetic field, helping them migrate toward low‐oxygen environments. This study reveals how Magnetospirillum gryphiswaldense uses a specialized flavin adenine dinucleotide (FAD)‐dependent chemoreceptor, composed of two interacting proteins, for precise navigation in oxygen gradients.

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

Mammalian transposable elements and their impacts on genome evolution

Chromosome Research, 2018
Transposable elements (TEs) are genetic elements with the ability to mobilize and replicate themselves in a genome. Mammalian genomes are dominated by TEs, which can reach copy numbers in the hundreds of thousands.

PTf‐SRiApt Targeting SCAF4‐POLR2A Interaction Suppresses Tumor Growth and Promotes Antitumor Immunity in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
A phosphorothioate‐modified aptamer PTf‐SRiApt capable of disrupting “undruggable” transcription factor SCAF4‐POLR2A interaction with high inhibitory activity and biological stability is presented here. Through this inhibition, PTf‐SRiApt successfully arrested cell cycle progression, induced cell death, and elevated immune recruitment in SCAF4‐POLR2A ...

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.

Auxin‐Producing Pseudomonas Recruited by Root Flavonoids Increases Rice Rhizosheath Formation through the Bacterial Histidine Kinase Under Soil Drying

Advanced Science, EarlyView.
Drought is a major cause of crop losses across agricultural regions. Rhizosheath formation enhances plant resistance to drought. Polyploids may tolerate stress more effectively through increased interactions with bacteria. However, the contributions of tetraploid rice associated microbiota to rhizosheath formation under soil drying remain unclear ...

Weight Cycling Deregulates Eating Behavior in Mice via the Induction of Durable Gut Dysbiosis

Advanced Science, EarlyView.
Weight cycling in Humans is suspected to dysregulate eating behavior. Mice submitted to body weight cycling by alternating western‐type and regular chow diets display increased hedonic appetite when exposed to a palatable diet, reminiscent of binge‐eating episodes.

Transposable Elements and Their Epigenetic Regulation in Mental Disorders: Current Evidence in the Field

Frontiers in Genetics, 2019
Transposable elements (TEs) are highly repetitive DNA sequences in the human genome that are the relics of previous retrotransposition events. Although the majority of TEs are transcriptionally inactive due to acquired mutations or epigenetic processes ...
