Benchmarker: An Unbiased, Association-Data-Driven Strategy to Evaluate Gene Prioritization Algorithms [PDF]

open access: yesThe American Journal of Human Genetics, 2018
Genome-wide association studies (GWAS) are valuable for understanding human biology, but associated loci typically contain multiple associated variants and genes. Thus, algorithms that prioritize likely causal genes and variants for a given phenotype can provide biological interpretations of association data.

A comparison and evaluation of five biclustering algorithms by quantifying goodness of biclusters for gene expression data [PDF]

open access: yesBioData Mining, 2012
Abstract Background Several biclustering algorithms have been proposed to identify biclusters, in which genes share similar expression patterns across a number of conditions. However, different algorithms would yield different biclusters and further lead to distinct conclusions. Therefore, some testing and comparisons

Detecting Cooperativity between Transcription Factors Based on Functional Coherence and Similarity of Their Target Gene Sets. [PDF]

open access: yesPLoS ONE, 2016
In eukaryotic cells, transcriptional regulation of gene expression is usually achieved by cooperative transcription factors (TFs). Therefore, knowing cooperative TFs is the first step toward uncovering the molecular mechanisms of gene expression ...

A two-stage hybrid gene selection algorithm combined with machine learning models to predict the rupture status in intracranial aneurysms

open access: yesFrontiers in Neuroscience, 2022
An IA is an abnormal swelling of cerebral vessels, and a subset of these IAs can rupture causing aneurysmal subarachnoid hemorrhage (aSAH), often resulting in death or severe disability.

Methods for evaluating clustering algorithms for gene expression data using a reference set of functional classes [PDF]

open access: yesBMC Bioinformatics, 2006
A cluster analysis is the most commonly performed procedure (often regarded as a first step) on a set of gene expression profiles. In most cases, a post hoc analysis is done to see if the genes in the same clusters can be functionally correlated. While past successes of such analyses have often been reported in a number of microarray studies (most of ...

Synstable Fusion: A Network-Based Algorithm for Estimating Driver Genes in Fusion Structures

open access: yesMolecules, 2018
Gene fusion structure is a class of common somatic mutational events in cancer genomes, which are often formed by chromosomal mutations. Identifying the driver gene(s) in a fusion structure is important for many downstream analyses and it contributes to ...

Comparison of algorithms for the analysis of Affymetrix microarray data as evaluated by co-expression of genes in known operons [PDF]

open access: yesNucleic Acids Research, 2006
Oligonucleotide microarrays are an informative tool to elucidate gene regulatory networks. In order for gene expression levels to be comparable across microarrays, normalization procedures have to be invoked. A large number of methods have been described to correct for systematic biases in microarray experiments.
