Apply for samples

BioResource biobanking We extract DNA from blood or saliva donated by our participants. The DNA is quality controlled, banked  and then analysed to study genetic variation by genotyping. We also store plasma and serum from blood samples. All samples are sent to the NIHR-funded National Biosample Centre (NBC) in Milton Keynes, for processing,…

Evidence of international transmission of mobile colistin resistant monophasic Salmonella Typhimurium ST34

Three samples of S. 4,[5],12:i:-, all isolated in 2010, harbored mcr-3.1. Two were from human stool and the other was from ready-to-eat frozen food. Phenotypic characterization confirmed that all three isolates were resistant to colistin, all with MIC and MBC of 8 µg/ml. WGS of H1-012, H1-014 and H1-120 were analyzed…

Coming Soon! Including Sample Location and Collection Date and Time for Sequences Submitted to GenBank and SRA – NCBI Insights

As previously announced, in collaboration with our partners at the International Nucleotide Sequence Database Collaboration (INSDC), we will begin to systematically gather ‘location of collection’ and ‘date and time of collection’ for sequence data submitted to GenBank and the Sequence Read Archive (SRA). Gathering information about where and when a…

Parkinson’s cure ‘inevitable’ after biomarker breakthrough

The Michael J. Fox Foundation for Parkinson’s Research (MJFF) has announced what it says is the ‘most significant breakthrough yet’ in the search for a Parkinson’s biomarker: a biological test for Parkinson’s disease. The test demonstrates high diagnostic accuracy, differentiates molecular subtypes and detects disease in individuals before cardinal movement…

Ethical Questions To Settle Ahead Of ‘Genetic Revolution’

A genetic revolution is coming. It’s time the medical community and policymakers discuss it. As technology advances and the price for genetic testing decreases, it is likely that within the next five years, DNA sequence information will be part of a patient’s medical records. Such a move would revolutionize the…

bioinformatics – How do I download a large number of GenBank sequences using entrez_fetch in R?

I am trying to download sequence data from 1283 records in GenBank using rentrez. I’m using the following code, first to search for records fitting my criteria, then linking across databases, and finally fetching the sequence data: # Search for sequence ids in biosample database search <- entrez_search(db = “biosample”,…

Petabase-scale sequence alignment catalyses viral discovery

Serratus alignment architecture Serratus (v0.3.0) (github.com/ababaian/serratus) is an open-source cloud-infrastructure designed for ultra-high-throughput sequence alignment against a query sequence or pangenome (Extended Data Fig. 1). Serratus compute costs are dependent on search parameters (expanded discussion available: github.com/ababaian/serratus/wiki/pangenome_design). The nucleotide vertebrate viral pangenome search (bowtie2, database size: 79.8 MB) reached processing rates…

Frontiers | DNA Methylation and RNA-Sequencing Analysis Show Epigenetic Function During Grain Filling in Foxtail Millet (Setaria italica L.)

Introduction Gene expression is not only controlled by DNA sequences but also by epigenetic marks in eukaryotes. DNA methylation as one of the important epigenetic modifications has been demonstrated as closely related to gene expression in biological processes, such as transcriptional activity, developmental regulation, and environmental responses (Maunakea et al.,…
