High-throughput nucleotide sequencing (often referred to as next-generation sequencing; NGS) is increasingly being chosen as a diagnostic tool for cases of expected but unresolved genetic origin. When exploring a higher number of genetic variants, there is a higher chance of detecting unsolicited findings. The consequential increased need for decisions on disclosure of these unsolicited finding...
One of the key problems in computational genomics is that of identifying structural variations between two sequences of genomic origin. Recently, with the advent of high-throughput sequencing of transcriptomes (RNA-seq), transcriptional structural variation studies also came into prominence. This study introduces two novel frameworks for aligning transcribed sequences to the genome with high se...
The approximately 21 nucleotide microRNAs (miRNAs) are one type of well-defined small RNA species, and they play critical roles in various biological processes in organisms. In plants, most miRNAs exert repressive regulation on their targets through cleavage, and a number of miRNA-target pairs have been validated either by modified 5' RACE (rapid amplification of cDNA ends), or by newly develop...
Problem statement: Pyrosequencing has the potential to rapidly and reliably sequence DNA taking advantages over traditional Sanger di-deoxy sequencing approach. Approach: A comprehensive review of the literature on the principles, applications, challenges and prospects of pyrosequencing was performed. Results: Pyrosequencing was a DNA sequencing technology based on the sequencing-by-synthesis p...
This numerical study provides an error analysis of an idealized nanopore sequencing method in which ionic current measurements are used to sequence intact single-stranded DNA in the pore, while an enzyme controls DNA motion. Examples of systematic channel errors when more than one nucleotide affects the current amplitude are detailed, which if present will persist regardless of coverage. Absent...
A Modified RNA-Seq Approach for Whole Genome Sequencing of RNA Viruses from Faecal and Blood Samples
To date, very large scale sequencing of many clinically important RNA viruses has been complicated by their high population molecular variation, which creates challenges for polymerase chain reaction and sequencing primer design. Many RNA viruses are also difficult or currently not possible to culture, severely limiting the amount and purity of available starting material. Here, we describe a s...
Cellular DNA/RNA tags (barcodes) allow for multiplexed cell lineage tracing and neuronal projection mapping with cellular resolution. Conventional approaches to reading out cellular barcodes trade off spatial resolution with throughput. Bulk sequencing achieves high throughput but sacrifices spatial resolution, whereas manual cell picking has low throughput. In situ sequencing could potentially...
A comprehensive map of transcription start sites (TSSs) across the highly AT-rich genome of P. falciparum would aid progress toward deciphering the molecular mechanisms that underlie the timely regulation of gene expression in this malaria parasite. Using high-throughput sequencing technologies, we generated a comprehensive atlas of transcription initiation events at single-nucleotide resolutio...
Several technologically sophisticated high-throughput techniques have been recently developed for the study of human single nucleotide polymorphisms and the diagnosis of point mutations in human diseases. However, there is also a need for simple and inexpensive techniques suitable for clinical services and small research laboratories. Minisequencing meets the latter requirements. It is simple, ...
