Pathway Based Genomics Prediction using Generalized Elastic Net

2016
PLoS Comput Biol
PMCID: 4784899
PMID: 26960204
DOI: 10.1371/journal.pcbi.1004790

[…] ctors to obtain a set of discriminative scores—one for each feature / gene—and then using gene sets to elucidate pathways saturated with highly discriminative scores. Gene Set Enrichment Analysis [], Significance Analysis of Function and Expression [], and a method by Lee, et al. [] do exactly this to arrive at a single differential score for each gene set of interest. Rather than using curated se […]

Investigating the concordance of Gene Ontology terms reveals the intra and inter platform reproducibility of enrichment analysis

2013
BMC Bioinformatics
PMCID: 3644270
PMID: 23627640

[…] improve the sensitivity and selectivity of GSEA []. Kim et al. used z-statistics and permutation test to identify significantly enriched gene sets []. In addition, other statistical methods including significance analysis of function and expression (SAFE) [], BayGO [], ProbCD [], EasyGO [], ProfCom [], GlobalANCOVA [], GOEAST [] and LRpath [] were also developed for enrichment analysis.Based on th […]

Chapter 8: Biological Knowledge Assembly and Interpretation

2012
PLoS Comput Biol
PMCID: 3531281
PMID: 23300429
DOI: 10.1371/journal.pcbi.1002858

[…] level applications. For example, researchers developed genomic signatures to identify the activation status of oncogenic pathways and predict the sensitivity to individual chemotherapeutic drugs , . Significance Analysis of Function and Expression (SAFE) extends GSEA to cover multiclass, continuous and survival phenotypes. It also provides more options for the test statistic, including Wilcoxon […]

Pathway analysis reveals functional convergence of gene expression profiles in breast cancer

2008
BMC Med Genomics
PMCID: 2447843
PMID: 18588682
DOI: 10.1186/1755-8794-1-28

[…] proaches have emerged in recent years to identify sets of biologically related genes that are deregulated as a group. Examples of gene-set analysis include the Gene Set Enrichment Analysis (GSEA) [], Significance Analysis of Function and Expression (SAFE) [], and the globaltest package [] These methods focus on groups of genes that share common biological functions such as cell cycle regulation; m […]

A Low Dose of Dietary Resveratrol Partially Mimics Caloric Restriction and Retards Aging Parameters in Mice

2008
PLoS One
PMCID: 2386967
PMID: 18523577
DOI: 10.1371/journal.pone.0002264

[…] are postulated to impact aging (IGF-1, insulin, Sirt1, oxidative stress), we analyzed the gene expression data for functional categories that may be affected with age, CR or resveratrol. We used the significance analysis of function and expression (SAFE), a two-stage, permutation-based method that can be applied to various experimental designs, accounts for the unknown correlation among genes and […]
