The role of mobile DNA elements in the dynamics of plant genome plasticity. [PDF]

open access: yesJ Exp Bot
Plants host a range of DNA elements capable of self-replication. These molecules, usually associated to the activity of transposable elements or viruses, are found integrated in the genome or in the form of extrachromosomal DNA.

ecDNA amplification of MYC drives intratumor copy-number heterogeneity and adaptation to stress in PDAC

open access: yesbioRxiv, 2023
Intratumor heterogeneity and phenotypic plasticity drive tumour progression and therapy resistance. Oncogene dosage variation contributes to cell state transitions and phenotypic heterogeneity, thereby providing a substrate for somatic evolution ...

Circlehunter: a tool to identify extrachromosomal circular DNA from ATAC-Seq data

open access: yesOncogenesis, 2023
In cancer, extrachromosomal circular DNA (ecDNA), or megabase-pair amplified circular DNA, plays an essential role in intercellular heterogeneity and tumor cell revolution because of its non-Mendelian inheritance.

Identification and characterization of extrachromosomal circular DNA in Wei and Large White pigs by high-throughput sequencing

open access: yesFrontiers in Veterinary Science, 2023
Wei pig (WP) and Large White pig (LP) are fatty and lean breeds, respectively. Extrachromosomal circular DNA (eccDNA) plays an important role in regulating signaling pathway processes of cell. However, there are few reports regarding the eccDNA and ecDNA

An effector of the Irish potato famine pathogen antagonizes a host autophagy cargo receptor [PDF]

open access: yes, 2016
Plants use autophagy to safeguard against infectious diseases. However, how plant pathogens interfere with autophagy-related processes is unknown. Here, we show that PexRD54, an effector from the Irish potato famine pathogen Phytophthora infestans, binds

Comprehensive analysis of clustered mutations in cancer reveals recurrent APOBEC3 mutagenesis of ecDNA [PDF]

open access: yes, 2021
ABSTRACTClustered somatic mutations are common in cancer genomes with prior analyses revealing several types of clustered single-base substitutions, including doublet- and multi-base substitutions, diffuse hypermutation termed omikli, and longer strand-coordinated events termed kataegis.

Amplification of Extrachromosomal Oncogene and Tumorigenesis and Development

open access: yesChinese Journal of Lung Cancer, 2020
Extrachromosomal DNA (ecDNA) is a small segment of circular DNA located outside the chromosome, which has the function of self-replication. Recently, amplification of oncogenes on ecDNA has been proved to be a common phenomenon in tumor cells, and has ...

Effect of SARS-CoV-2 Infection and COVID-19 Vaccination on Oxidative Status of Human Placenta: A Preliminary Study

open access: yesAntioxidants, 2023
Infection with SARS-CoV-2 during pregnancy increases the risk of pregnancy complications associated with inflammation, which could lead to oxidative stress in the placenta. Whether vaccination against COVID-19 has any effect is unclear.

New hints towards a precision medicine strategy for IDH wild-type glioblastoma. [PDF]

open access: yes, 2020
Glioblastoma represents the most common primary malignancy of the central nervous system in adults and remains a largely incurable disease. The elucidation of disease subtypes based on mutational profiling, gene expression and DNA methylation has so far ...

EGFR, the Lazarus target for precision oncology in glioblastoma [PDF]

open access: yes, 2022
The Lazarus effect is a rare condition that happens when someone seemingly dead shows signs of life. The epidermal growth factor receptor (EGFR) represents a target in the fatal neoplasm glioblastoma (GBM) that through a series of negative clinical ...
