This study reports a novel strategy for preparing a biocompatible adhesive hydrogel crosslinked with a muscle tissue‐derived extracellular matrix (MEM) for in situ muscle regeneration. As a natural crosslinker, MEM not only mediates combinatorial polymer networks but also stimulates satellite cells to induce a cell‐free therapeutic solution.

The CCCTC-binding factor (CTCF) of Drosophila contributes to the regulation of the ribosomal DNA and nucleolar stability. [PDF]
In the repeat array of ribosomal DNA (rDNA), only about half of the genes are actively transcribed while the others are silenced. In arthropods, transposable elements interrupt a subset of genes, often inactivating transcription of those genes. Little is

Chromosomal rearrangements and transposable elements in locally adapted island Drosophila [PDF]
Chromosomal rearrangements, particularly those mediated by transposable elements (TEs), can drive adaptive evolution by creating chimeric genes, inducing de novo gene formation, or altering gene expression. Here, we investigate rearrangements evolutionary role during habitat shifts in two locally adapted populations, Drosphila santomea and Drosphila ...

Evolutionary genomics of transposable elements in Saccharomyces cerevisiae [PDF]
Saccharomyces cerevisiae is one of the premier model systems for studying the genomics and evolution of transposable elements. The availability of the S. cerevisiae genome led to many insights into its five known transposable element families (Ty1-Ty5) in the years shortly after its completion.

DNA modification of a maize transposable element correlates with loss of activity. [PDF]
An unstable allele of the bronze 2 (bz2) locus was isolated from a Robertson's Mutator Zea mays line containing a family of active transposable Mu elements. This mutation is somatically unstable, resulting in numerous revertant purple sectors on a bronze kernel. By following the variegated kernel phenotype through two generations, several lineages have

A region‐wise functional connectivity dynamics (FCD) switching index (RFSI) identifies abnormal drivers in ASD across development, linked to salience/ventral attention, default mode, and frontoparietal networks. RFSI changes correlate with transcriptomic and neurotransmitter profiles, and supported by gene‐edited ASD monkeys.

Background Switchgrass is a crop with many desirable traits for bioenergy production. Plant genomes have high DNA methylation levels throughout genes and transposable elements and DNA methylation is known to play a role in silencing transposable elements.

Transposable elements drive widespread expression of oncogenes in human cancers
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.

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

Based on a well‐established in vitro directed differentiation model and an integrated analysis of high‐density cell lineage trees (CLTs) and single‐cell transcriptomes, it is demonstrated that many subclones are formed by sub‐CLTs resembling each other in terms of both cell type compositions and topological structures.
