The quantification of the biological diversity in environmental samples using high-throughput DNA sequencing is hindered by PCR bias caused variable primer-template mismatches individual species. In some dietary studies, there added problem that are enriched with predator DNA, so often a predator-specific blocking oligonucleotide used to alleviate problem. However, specific oligonucleotides could coblock nontarget species degree. Here, we accurately estimate extent biases induced universal...

Abstract Merkel cell carcinoma (MCC) is an uncommon, but highly malignant, cutaneous tumor. polyoma virus (MCV) has been implicated in a majority of MCC tumors; however, viral-negative tumors have reported to be more prevalent some geographic regions subject high sun exposure. While the impact MCV and viral T-antigens on development extensively investigated, little known about etiology tumors. We performed targeted capture massively parallel DNA sequencing 619 cancer genes compare gene...

Abstract Predicting whether a predator is capable of affecting the dynamics prey species in field implies analysis complete diet predator, not simply rates predation on target taxon. Here, we employed Ion Torrent next‐generation sequencing technology to investigate generalist arthropod predator. A dietary requires use general primers, but these will also amplify unless suppressed using blocking probe. However, probes can potentially block other species, particularly if they are...

Several novel therapeutics are poised to change the natural history of chronic lymphocytic leukaemia (CLL) and increasing use these therapies has highlighted limitations traditional disease monitoring methods. Here we demonstrate that circulating tumour DNA (ctDNA) is readily detectable in patients with CLL. Importantly, ctDNA does not simply mirror genomic information contained within malignant lymphocytes but instead parallels changes across different compartments following treatment...

Low-grade serous ovarian carcinomas (LGSC) are associated with a poor response to chemotherapy and molecularly characterized by RAS pathway activation. Using exome whole genome sequencing, we identified recurrent mutations in the protein translational regulator EIF1AX NF1, USP9X, KRAS, BRAF, NRAS were mutually exclusive; however, found significant co-occurrence of Missense clustered at N-terminus region its role ensuring initiation fidelity. Coexpression mutant proteins promoted...

Lupin products may be valuable as human foods because of their high protein content and potential anticholesterolemic properties. However, a small percentage the population is allergic to lupin. In this study, we use in vitro IgE binding mass spectrometry identify conglutin β, major storage protein, an allergen seeds Lupinus angustifolius albus. Purification β from L. flour confirmed that serum binds protein. Where sera recognized lupin proteins on Western blots, it suggesting for The has...

ALK, ROS1 and RET gene fusions are important predictive biomarkers for tyrosine kinase inhibitors in lung cancer. Currently, the gold standard method fusion detection is Fluorescence In Situ Hybridization (FISH) while highly sensitive specific, it also labour intensive, subjective analysis, unable to screen a large numbers of fusions. Recent developments high-throughput transcriptome-based methods may provide suitable alternative FISH as they compatible with multiplexing diagnostic...
