Extracellular Matrix‐Mediated Crosslinking of Adhesive Hyaluronic Acid Patch for Treating Volumetric Muscle Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
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]

open access: yesPLoS ONE, 2011
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]

open access: yesarXiv, 2021
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]

open access: yesCarr M, Bensasson D, Bergman CM (2012) Evolutionary Genomics of Transposable Elements in Saccharomyces cerevisiae. PLoS ONE 7(11): e50978, 2012
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]

open access: yesProceedings of the National Academy of Sciences, 1986
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

Disentangling the Switching Behavior in Functional Connectivity Dynamics in Autism Spectrum Disorder: Insights from Developmental Cohort Analysis and Molecular‐Cellular Associations

open access: yesAdvanced Science, EarlyView.
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.

Analyses of methylomes of upland and lowland switchgrass (Panicum virgatum) ecotypes using MeDIP-seq and BS-seq

open access: yesBMC Genomics, 2017
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

open access: yesNature 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.

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

open access: yesViruses, 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.

Stereotyped Subclones Revealed by High‐Density Single‐Cell Lineage Tracing Support Robust Development

open access: yesAdvanced Science, EarlyView.
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.
