srnaMapper: an optimal mapping tool for sRNA-Seq readsBMC Bioinformatics - Tập 23 - Trang 1-19 - 2022
Matthias Zytnicki, Christine Gaspin
Sequencing is the key method to study the impact of short RNAs, which include
micro RNAs, tRNA-derived RNAs, and piwi-interacting RNA, among others. The first
step to make use of these reads is to map them to a genome. Existing mapping
tools have been developed for long RNAs in mind, and, so far, no tool has been
conceived for short RNAs. However, short RNAs have several distinctive features
which... hiện toàn bộ
RRCRank: a fusion method using rank strategy for residue-residue contact predictionBMC Bioinformatics - Tập 18 - Trang 1-12 - 2017
Xiaoyang Jing, Qiwen Dong, Ruqian Lu
In structural biology area, protein residue-residue contacts play a crucial role
in protein structure prediction. Some researchers have found that the predicted
residue-residue contacts could effectively constrain the conformational search
space, which is significant for de novo protein structure prediction. In the
last few decades, related researchers have developed various methods to predict
res... hiện toàn bộ
A new protein-ligand binding sites prediction method based on the integration of protein sequence conservation informationBMC Bioinformatics - Tập 12 - Trang 1-7 - 2011
Tianli Dai, Qi Liu, Jun Gao, Zhiwei Cao, Ruixin Zhu
Prediction of protein-ligand binding sites is an important issue for protein
function annotation and structure-based drug design. Nowadays, although many
computational methods for ligand-binding prediction have been developed, there
is still a demanding to improve the prediction accuracy and efficiency. In
addition, most of these methods are purely geometry-based, if the prediction
methods improve... hiện toàn bộ
Practical application of a Bayesian network approach to poultry epigenetics and stressBMC Bioinformatics - Tập 23 - Trang 1-16 - 2022
Emiliano A. Videla Rodriguez, Fábio Pértille, Carlos Guerrero-Bosagna, John B. O. Mitchell, Per Jensen, V. Anne Smith
Relationships among genetic or epigenetic features can be explored by learning
probabilistic networks and unravelling the dependencies among a set of given
genetic/epigenetic features. Bayesian networks (BNs) consist of nodes that
represent the variables and arcs that represent the probabilistic relationships
between the variables. However, practical guidance on how to make choices among
the wide ... hiện toàn bộ
libgapmis: extending short-read alignmentsBMC Bioinformatics - Tập 14 - Trang 1-14 - 2013
Nikolaos Alachiotis, Simon Berger, Tomáš Flouri, Solon P Pissis, Alexandros Stamatakis
A wide variety of short-read alignment programmes have been published recently
to tackle the problem of mapping millions of short reads to a reference genome,
focusing on different aspects of the procedure such as time and memory
efficiency, sensitivity, and accuracy. These tools allow for a small number of
mismatches in the alignment; however, their ability to allow for gaps varies
greatly, with ... hiện toàn bộ
Identifying microRNA targets in different gene regionsBMC Bioinformatics - Tập 15 - Trang 1-11 - 2014
Wenlong Xu, Anthony San Lucas, Zixing Wang, Yin Liu
Currently available microRNA (miRNA) target prediction algorithms require the
presence of a conserved seed match to the 5' end of the miRNA and limit the
target sites to the 3' untranslated regions of mRNAs. However, it has been noted
that these requirements may be too stringent, leading to a substantial number of
missing targets. We have developed TargetS, a novel computational approach for
predi... hiện toàn bộ
Bioinformatics analysis of transcriptional regulation of circadian genes in rat liverBMC Bioinformatics - Tập 15 Số 1 - 2014
Tung Thanh Nguyen, John Mattick, Qian Yang, Mehmet A. Orman, Marianthi Ierapetritou, François Berthiaume, Ioannis P. Androulakis
Abstract Background The circadian clock is a critical regulator of biological
functions controlling behavioral, physiological and biochemical processes.
Because the liver is the primary regulator of metabolites within the mammalian
body and the disruption of circadian rhythms in liver is associated with severe
illness, circadian regulators would play a strong role in maintaining liver
function. Ho... hiện toàn bộ
Automatic plankton image classification combining multiple view features via multiple kernel learningBMC Bioinformatics - Tập 18 - Trang 1-18 - 2017
Haiyong Zheng, Ruchen Wang, Zhibin Yu, Nan Wang, Zhaorui Gu, Bing Zheng
Plankton, including phytoplankton and zooplankton, are the main source of food
for organisms in the ocean and form the base of marine food chain. As the
fundamental components of marine ecosystems, plankton is very sensitive to
environment changes, and the study of plankton abundance and distribution is
crucial, in order to understand environment changes and protect marine
ecosystems. This study w... hiện toàn bộ
Fold change rank ordering statistics: a new method for detecting differentially expressed genesBMC Bioinformatics - Tập 15 - Trang 1-15 - 2014
Doulaye Dembélé, Philippe Kastner
Different methods have been proposed for analyzing differentially expressed (DE)
genes in microarray data. Methods based on statistical tests that incorporate
expression level variability are used more commonly than those based on fold
change (FC). However, FC based results are more reproducible and biologically
relevant. We propose a new method based on fold change rank ordering statistics
(FCROS... hiện toàn bộ
Consolidating metabolite identifiers to enable contextual and multi-platform metabolomics data analysisBMC Bioinformatics - Tập 11 - Trang 1-11 - 2010
Henning Redestig, Miyako Kusano, Atsushi Fukushima, Fumio Matsuda, Kazuki Saito, Masanori Arita
Analysis of data from high-throughput experiments depends on the availability of
well-structured data that describe the assayed biomolecules. Procedures for
obtaining and organizing such meta-data on genes, transcripts and proteins have
been streamlined in many data analysis packages, but are still lacking for
metabolites. Chemical identifiers are notoriously incoherent, encompassing a
wide range ... hiện toàn bộ
