1H nuclear magnetic resonance (NMR) spectroscopy-based metabolic phenotyping is now widely used for large-scale epidemiological applications. To minimize signal overlap present in 1D 1H NMR spectra, we have investigated the use of 2D J-resolved (JRES) 1H NMR spectroscopy for large-scale phenotyping ...
The transcription of the cldEFGC gene cluster of Bifidobacterium breve UCC2003 was shown to be induced upon growth on cellodextrins, implicating these genes in the metabolism of these sugars. Phenotypic analysis of a B. breve UCC2003::cldE insertion mutant confirmed that the cld gene cluster is excl...
Although most ovarian cancers show prognostically relevant activated T-cell infiltrates, response rates to immune checkpoint inhibitors are very modest4. Memory B-cell and plasma cell infiltrates have been associated with better outcome in ovarian cancer, but the nature and functional relevance of t...
Despite their long half-life, therapeutic antibodies are considered ineffective against intracellular antigens due to their perceived inability to penetrate epithelial cells. Using recombinant antibodies targeting common mutations in oncogenes, we show that dimeric IgA, but not the same antibody on ...
Whole genome sequencing (WGS) from snap-frozen oesophageal tumour tissue and germline nucleic acids isolated from peripheral blood mononuclear cells (PBMC) was performed as part of the International Cancer Genome Consortium project and OCCAMS consortium (1,2). Filtered read sequences were mapped to ...
Growth of B. breve UCC2003 on ribose leads to the transcriptional induction of the rbsACBDK gene cluster. Generation and phenotypic analysis of an rbsA insertion mutant established that the rbs gene cluster is essential for ribose utilization, and that its transcription is likely regulated by a LacI...
Extracellular chemical cues constitute much of the language of life among marine organisms from microbes to mammals. These chemical cues shape foraging and feeding strategies, symbiotic interactions, selection of mates and habitats, and the transfer of energy and nutrient...
We performed microarray CGH analysis of 104 neuropathogenic and enteritis only stains of C. jejuni. Keywords: Individual hybridizations, CGH We measured signal intensity for tester strain versus control strain Cj NCTC 11168 for 104 isolates of C. jejuni.
We report that intratumoral Tertiary Lymphoid Structures (TLS) in human ovarian cancer contain highly oligoclonal B cells that produce IgA and IgG. Using a recombinant antibody cloned from the dominant sequence of an ovarian cancer TLS, we abrogated the growth of the autologous human tumor in vivo, ...
