PMID: 23504936
Curr Protoc Bioinformatics. 2013 Mar;Unit 8.17. doi: 10.1002/0471250953.bi0817s41.

Although individual tumors show surprisingly diverse genomic alterations, these events tend to occur in a limited number of pathways, and alterations that affect the same pathway tend to not co-occur in the same patient. While pathway analysis has been...

UNLABELLED: SpotXplore is a plugin for Cytoscape for extraction and visualization of differentially expressed subnetworks (hotspots) from gene networks. The hotspot-based visualization approach enables interactive exploration of regulatory interactions in differentially expressed gene sets, and it allows a researcher...

uKIN Combines New and Prior Information with Guided Network Propagation to Accurately Identify Disease Genes.

Cell systems

Hristov BH, Chazelle B, Singh M.
PMID: 32684276
Cell Syst. 2020 Jun 24;10(6):470-479.e3. doi: 10.1016/j.cels.2020.05.008. Epub 2020 Jun 24.

Protein interaction networks provide a powerful framework for identifying genes causal for complex genetic diseases. Here, we introduce a general framework, uKIN, that uses prior knowledge of disease-associated genes to guide, within known protein-protein interaction networks, random walks that...

Tissue-specific Network Analysis of Genetic Variants Associated with Coronary Artery Disease.

Scientific reports

Miao X, Chen X, Xie Z, Lin H.
PMID: 30065343
Sci Rep. 2018 Jul 31;8(1):11492. doi: 10.1038/s41598-018-29904-7.

Coronary artery disease (CAD) is a leading cause of death worldwide. Recent genome-wide association studies have identified more than one hundred susceptibility loci associated with CAD. However, the underlying mechanism of these genetic loci to CAD susceptibility is still...

Structural Bistability Analysis of Flower-Shaped and Chain-Shaped Boolean Networks.

IEEE/ACM transactions on computational biology and bioinformatics

Azuma SI, Kure T, Sugie T.
PMID: 31107657
IEEE/ACM Trans Comput Biol Bioinform. 2020 Nov-Dec;17(6):2098-2106. doi: 10.1109/TCBB.2019.2917196. Epub 2020 Dec 08.

Bistability, i.e., the existence of just two stable equilibria, is known to play an important role in biological systems, e.g., cellular differentiation and apoptosis. In this paper, we consider the bistability but as a structural property of a class...

Identification of Hub Genes Associated with Hypertension and Their Interaction with miRNA Based on Weighted Gene Coexpression Network Analysis (WGCNA) Analysis.

Medical science monitor : international medical journal of experimental and clinical research

Li Z, Chyr J, Jia Z, Wang L, Hu X, Wu X, Song C.
PMID: 32888289
Med Sci Monit. 2020 Sep 05;26:e923514. doi: 10.12659/MSM.923514.

BACKGROUND Hypertension is one of the most widespread health conditions in the world, and the molecular mechanism of it is still unclear. In this study, we identified the hub genes (hub miRNA genes) associated with hypertension and explored the...

miRspongeR: an R/Bioconductor package for the identification and analysis of miRNA sponge interaction networks and modules.

BMC bioinformatics

Zhang J, Liu L, Xu T, Xie Y, Zhao C, Li J, Le TD.
PMID: 31077152
BMC Bioinformatics. 2019 May 10;20(1):235. doi: 10.1186/s12859-019-2861-y.

BACKGROUND: A microRNA (miRNA) sponge is an RNA molecule with multiple tandem miRNA response elements that can sequester miRNAs from their target mRNAs. Despite growing appreciation of the importance of miRNA sponges, our knowledge of their complex functions remains...

Multistability and Bifurcation Analysis of Inhibitory Coupled Cyclic Genetic Regulatory Networks With Delays.

IEEE transactions on nanobioscience

Ling G, Guan ZH, Hu B, Lai Q, Wu Y.

Many biological systems have the conspicuous property to present more than one stable state and diverse rhythmic behaviors. A closed relationship between these complex dynamic behaviors and cyclic genetic structures has been witnessed by pioneering works. In this paper,...

SERGIO: A Single-Cell Expression Simulator Guided by Gene Regulatory Networks.

Cell systems

Dibaeinia P, Sinha S.
PMID: 32871105
Cell Syst. 2020 Sep 23;11(3):252-271.e11. doi: 10.1016/j.cels.2020.08.003. Epub 2020 Aug 31.

A common approach to benchmarking of single-cell transcriptomics tools is to generate synthetic datasets that statistically resemble experimental data. However, most existing single-cell simulators do not incorporate transcription factor-gene regulatory interactions that underlie expression dynamics. Here, we present SERGIO,...
