NEMo: An Evolutionary Model With Modularity for PPI Networks

Bernard Moret, Xiuwei Zhang, Min Ye, Qijia Jiang, Gabriela Clara Racz

Modeling the evolution of biological networks is a major challenge. Biological networks are usually represented as graphs; evolutionary events not only include addition and removal of vertices and edges but also duplication of vertices and their associated ...

New Genome Similarity Measures based on Conserved Gene Adjacencies

Bernard Moret, Shachi Shailesh Deshpande

Many important questions in molecular biology, evolution, and biomedicine can be addressed by comparative genomic approaches. One of the basic tasks when comparing genomes is the definition of measures of similarity (or dissimilarity) between two genomes, ...

On Computing Breakpoint Distances for Genomes with Duplicate Genes

Bernard Moret, Mingfu Shao

A fundamental problem in comparative genomics is to compute the distance between two genomes in terms of its higher level organization (given by genes or syntenic blocks). For two genomes without duplicate genes, we can easily define (and almost always eff ...

KRAB zinc-finger proteins contribute to the evolution of gene regulatory networks

Didier Trono, Michaël Imbeault, Pierre-Yves Joseph Laurent Helleboid

The human genome encodes some 350 Kruppel-associated box (KRAB) domain-containing zinc-finger proteins (KZFPs), the products of a rapidly evolving gene family that has been traced back to early tetrapods(1,2). The function of most KZFPs is unknown, but a f ...

From next-generation resequencing reads to a high-quality variant data set

Susanne Petra Pfeifer

Sequencing has revolutionized biology by permitting the analysis of genomic variation at an unprecedented resolution. High-throughput sequencing is fast and inexpensive, making it accessible for a wide range of research topics. However, the produced data c ...

Models and Algorithms in Biological Network Evolution with Modularity

Min Ye

Networks are commonly used to represent key processes in biology; examples include transcriptional regulatory networks, protein-protein interaction (PPI) networks, metabolic networks, etc. Databases store many such networks, as graphs, observed or inferred ...

A practical qPCR approach to detect TERRA, the elusive telomeric repeat-containing RNA

Joachim Lingner, Marianna Feretzaki

Telomeres, the heterochromatic structures that protect the ends of the chromosomes, are transcribed into a class of long non-coding RNAs, telomeric repeat-containing RNAs (TERRA), whose transcriptional regulation and functions are not well understood. The ...

A Fast and Exact Algorithm for the Exemplar Breakpoint Distance

Bernard Moret, Mingfu Shao

A fundamental problem in comparative genomics is to compute the distance between two genomes. For two genomes without duplicate genes, we can easily compute a variety of distance measures in linear time, but the problem is NP-hard under most models when ge ...

Topological Domains, Metagenes, and the Emergence of Pleiotropic Regulations at Hox Loci

Denis Duboule, Fabrice Daniel Darbellay

Hox gene clusters of jaw vertebrates display a tight genomic organization, which has no equivalent in any other bilateria genomes sequenced thus far. It was previously argued that such a topological consolidation toward a condensed, metagenic structure was ...

Gene Network Polymorphism Illuminates Loss and Retention of Novel RNAi Silencing Components in the Cryptococcus Pathogenic Species Complex

Marianna Feretzaki

RNAi is a ubiquitous pathway that serves central functions throughout eukaryotes, including maintenance of genome stability and repression of transposon expression and movement. However, a number of organisms have lost their RNAi pathways, including the mo ...
