Transposable elements as essential elements in the control of gene expression

Mobile DNA, 2023
Interspersed repetitions called transposable elements (TEs), commonly referred to as mobile elements, make up a significant portion of the genomes of higher animals.

An age-of-allele test of neutrality for transposable element insertions [PDF]

, 2013
How natural selection acts to limit the proliferation of transposable elements (TEs) in genomes has been of interest to evolutionary biologists for many years.

Changes in global gene expression in response to chemical and genetic perturbation of chromatin structure. [PDF]

PLoS ONE, 2011
DNA methylation is important for controlling gene expression in all eukaryotes. Microarray analysis of mutant and chemically-treated Arabidopsis thaliana seedlings with reduced DNA methylation revealed an altered gene expression profile after treatment ...

Chromosome-level comparative genomics and host-specific fungal transcriptomics uncover adaptive virulence strategies in the sugarcane smut pathogen

BMC Genomics
Background Sporisorium scitamineum is the causal agent of sugarcane smut, affecting global sugarcane production. Despite advances in smut genomics, the relationships between fungal genetic diversity, host adaptation, and virulence remain elusive. Methods

The 5' untranslated region of the I factor, a long interspersed nuclear element-like retrotransposon of Drosophila melanogaster, contains an internal promoter and sequences that regulate expression [PDF]

, 1993
The I-R system of hybrid dysgenesis in Drosophila melanogaster is controlled by a long interspersed nuclear element-like retroposon, the I factor.

Hematopoietic (stem) cells—The elixir of life?

FEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Characterization of active transposable elements and their new insertions in tuber propagated greater yam (Dioscorea alata)

BMC Genomics
Background Greater yam is a key staple crop grown in tropical and subtropical regions, while its asexual propagation mode had led to non-flowering mutations. How transposable elements contribute to its genetic variations is rarely analyzed.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

FEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

Transposon variants and their effects on gene expression in arabidopsis [PDF]

, 2013
Transposable elements (TEs) make up the majority of many plant genomes. Their transcription and transposition is controlled through siRNAs and epigenetic marks including DNA methylation.

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
