Diving Deeper Into Mechanisms of Acrylamide‐Induced Toxicity: RNA Sequencing Reveals Transcriptomic Alteration and Retrotransposon Expression in Drosophila melanogaster

Environmental Toxicology, EarlyView.
ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.

The diversity of LTR retrotransposons.

Genome biology, 2004
Eukaryotic genomes are full of long terminal repeat (LTR) retrotransposons. Although most LTR retrotransposons have common structural features and encode similar genes, there is nonetheless considerable diversity in their genomic organization, reflecting the different strategies they use to proliferate within the genomes of their hosts.

Transposons as Tools for Future Genome Engineering in Yeasts and Filamentous Fungi

Yeast, EarlyView.
Applications of transposon‐based tools for genome engineering in fungi include transposon‐mediated mutagenesis and targeted genomic integration. ABSTRACT Transposons are fundamental genetic elements that have profoundly shaped the architecture of eukaryotic genomes.

Chromosome‐Level Genome Assemblies of Two Softshell Turtles with ZZ/ZW Provide Insights into TE‐Driven Recombination Suppression in Sex Chromosomes

Integrative Zoology, EarlyView.
This study presents the first genomic identification and characterization of ZW sex chromosomes in two soft‐shelled turtle species through genome assembly and resequencing. We reveal the structural organization of ZW chromosomes, identifying both pseudoautosomal regions (PARs) and differentiated regions.

Sperm Mitochondrial DNA Copy Number and Nuclear DNA Methylation Across Clinical and Non‐Clinical Preconception Cohorts

Andrology, EarlyView.
ABSTRACT Background Sperm mitochondrial DNA copy number is an emerging marker of male fertility, with elevated mtDNAcn associated with poor semen quality across various populations. Sperm DNA methylation has also been previously demonstrated to be negatively correlated with semen parameters in IVF cohorts.

Retrotransposons and the Eternal Leaves

, 2012
The resurrection plant Craterostigma plantagineum can tolerate up to 96% loss of its relative water content and recover within hours after rehydration. In callus tissue desiccation tolerance is induced by pre-incubation with Abscisic acid (ABA). In callus and plant ABA treatment and dehydration induce a set of dehydration-responsive genes.

Long non‐coding RNAs at the crossroads of inflammation, cancer and angiogenesis: Molecular mechanisms and their potential as therapeutic targets

British Journal of Pharmacology, EarlyView.
Long non‐coding RNAs (lncRNAs), a broad class of non‐protein‐coding RNAs, are characterized as new regulators of gene expression at the epigenetic, transcriptional, and post‐transcriptional level. Thus, lncRNAs are involved in the regulation of physiological processes and the development of human diseases and cancer by modulating proinflammatory ...

Evolutionary history of Oryza sativa LTR retrotransposons: a preliminary survey of the rice genome sequences

BMC Genomics, 2004
Background LTR Retrotransposons transpose through reverse transcription of an RNA intermediate and are ubiquitous components of all eukaryotic genomes thus far examined.

Retrotransposons and Diabetes Mellitus

Epigenomes
Retrotransposons are invasive genetic elements, which replicate by copying and pasting themselves throughout the genome in a process called retrotransposition. The most abundant retrotransposons by number in the human genome are Alu and LINE-1 elements, which comprise approximately 40% of the human genome.

Oncogenic BRAF and KRAS Promote Global DNA Hypomethylation Through a Directed Pathway That Upregulates TET3

Cancer Science, EarlyView.
Oncogenic BRAF and KRAS promote global DNA hypomethylation through a directed pathway that increases the levels of TET3, which helps drive tumorigenesis. ABSTRACT Aberrant epigenetic modification is one of the characteristics of the cancer genome.
