Ethidium bromide provides a simple tool for identifying genuine DNA-independent protein associations [PDF]

, 1992
DNA-dependent and DNA-independent associations of DNA-binding proteins are important in transcriptional regulation. The analysis of DNA-independent associations frequently relies on assaying protein interaction in the absence of target DNA sequences.

Mycobacterium avium Subsp. paratuberculosis and Human Endogenous Retrovirus in Italian Patients With Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS)

Immunology, EarlyView.
Inflammatory bowel disease (IBD), comprising ulcerative colitis (UC) and Crohn's disease (CD), is a recognised gastrointestinal disorder. Mycobacterium avium subspecies paratuberculosis (MAP) is implicated in IBD pathogenesis. Persistent exposure and active infections by MAP may contribute to the unsilencing of human endogenous retroviruses (HERV ...

A cryptic targeting signal creates a mitochondrial FEN1 isoform with tailed R-Loop binding properties.

PLoS ONE, 2013
A growing number of DNA transacting proteins is found in the nucleus and in mitochondria, including the DNA repair and replication protein Flap endonuclease 1, FEN1. Here we show a truncated FEN1 isoform is generated by alternative translation initiation,

A fractal pattern of hierarchical genetic population structure in mixed stocks across fish segregated by dams revealed by genomic resources for curimba Prochilodus lineatus

Journal of Fish Biology, EarlyView.
Abstract Genomic resources, new microsatellite markers and a novel observation of a fractal pattern in the genetic population structure are presented for curimba, Prochilodus lineatus, a freshwater migratory model species of South America. Our main goals were to investigate the presence of mixed fish stocks and the effects of damming‐induced ...

First direct evidence of spawning by Japanese sardine Sardinops melanosticta (Temminck and Schlegel) in the eastern Pacific Ocean

Journal of Fish Biology, EarlyView.
Abstract In 2022 the presence of the Japanese sardine, Sardinops melanosticta (Temminck and Schlegel), was detected in the eastern Pacific Ocean, far outside its known western North Pacific range. The species was collected along with the Pacific sardine, Sardinops sagax (Jenyns), which is native to the eastern Pacific Ocean.

DNA extracted from boiled archival fish bones yields high‐quality whole‐genome sequencing data

Journal of Fish Biology, EarlyView.
Abstract Archival samples provide a unique source of organismal DNA, offering the potential to extend the temporal scale of genetic studies by decades to centuries. Fish hard structures, such as otoliths and scales, serve as records for fish collected during fisheries monitoring across a large spatiotemporal scale.
