Biological impacts and context of network theory

E Almaas - Journal of Experimental Biology, 2007 - journals.biologists.com
Many complex systems can be represented and analyzed as networks, and examples that
have benefited from this approach span the natural sciences. For instance, we now know …

Eigengene networks for studying the relationships between co-expression modules

P Langfelder, S Horvath - BMC systems biology, 2007 - Springer
Background There is evidence that genes and their protein products are organized into
functional modules according to cellular processes and pathways. Gene co-expression …

Clustering in complex directed networks

G Fagiolo - Physical Review E, 2007 - APS
Many empirical networks display an inherent tendency to cluster, ie, to form circles of
connected nodes. This feature is typically measured by the clustering coefficient (CC). The …

Generalizations of the clustering coefficient to weighted complex networks

J Saramäki, M Kivelä, JP Onnela, K Kaski, J Kertesz - Physical Review E, 2007 - APS
The recent high level of interest in weighted complex networks gives rise to a need to
develop new measures and to generalize existing ones to take the weights of links into …

Gene network interconnectedness and the generalized topological overlap measure

AM Yip, S Horvath - BMC bioinformatics, 2007 - Springer
Background Network methods are increasingly used to represent the interactions of genes
and/or proteins. Genes or proteins that are directly linked may have a similar biological …

Understanding network concepts in modules

J Dong, S Horvath - BMC systems biology, 2007 - Springer
Background Network concepts are increasingly used in biology and genetics. For example,
the clustering coefficient has been used to understand network architecture; the connectivity …

Weighted gene coexpression network analysis strategies applied to mouse weight

TF Fuller, A Ghazalpour, JE Aten, TA Drake… - Mammalian …, 2007 - Springer
Abstract Systems-oriented genetic approaches that incorporate gene expression and
genotype data are valuable in the quest for genetic regulatory loci underlying complex traits …

Computational prediction of cancer-gene function

P Hu, G Bader, DA Wigle, A Emili - Nature Reviews Cancer, 2007 - nature.com
Most cancer genes remain functionally uncharacterized in the physiological context of
disease development. High-throughput molecular profiling and interaction studies are …

Constructing gene co-expression networks and predicting functions of unknown genes by random matrix theory

F Luo, Y Yang, J Zhong, H Gao, L Khan… - BMC …, 2007 - Springer
Background Large-scale sequencing of entire genomes has ushered in a new age in
biology. One of the next grand challenges is to dissect the cellular networks consisting of …

Network neighborhood analysis with the multi-node topological overlap measure

A Li, S Horvath - Bioinformatics, 2007 - academic.oup.com
Motivation: The goal of neighborhood analysis is to find a set of genes (the neighborhood)
that is similar to an initial 'seed'set of genes. Neighborhood analysis methods for network …
