Special Issue Information

Dear Colleagues,

Using networks to visualize knowledge and results helps readers to understand complex molecular interactions and relationships more easily. A single pathway sketch can contain dozens of interconnected molecules or chemicals and can still be understood by a human. Recently-established high-throughput technologies have led to a surge in newly-generated knowledge on molecular interactions in biology and medicine. The computational representation of biological networks facilitates new opportunities of data and knowledge exchange between researchers, and asserts a common vocabulary and understanding of underlying principles. Standards, methods and tools to visualize networks are continuously evolving in order to keep up with biomedical research and technological advances. In this Special Issue, we would like to invite submissions of original research and short communications on software tools, as well as review articles on topics related to “Network Visualization and Visual Network Analysis”. We look forward to receiving your contributions.

Tentative Abstract: Network medicine relies on different types of networks: from molecular level of protein-protein interactions to gene regulatory network and correlation studies of gene expression. Among the regulatory networks, the past few years have witnessed the increasing interest on the regulatory mechanism of some long noncoding RNA (lncRNA) that can act as competing endogenous RNAs (ceRNAs) for messenger RNAs (mRNAs) by sharing the binding site for microRNAs (miRNAs).

     We discuss a data-driven model developed to explore the lncRNA-associated ceRNA activity in breast invasive carcinoma [1]. The authors built normal and cancer networks of miRNA-mediated sponge interactions (MMI-networks and highlighted a marked rewiring in the ceRNA program between normal and pathological breast tissue. At the heart of this phenomenon is the widely studied oncogene PVT1 that switches from being the first hub in the normal MMI-network to fall outside the list of nodes of the cancer network. Interestingly, PVT1 revealed a net binding preference towards the mir-200 family as the bone of contention with its rival mRNAs known to be related to the cancer development and progression (e.g. GATA3, CDH1, TP53, TP63, TP73, RUNX1, and RUNX3). The authors sought the rationale behind the withdrawal in breast cancer tissues of the PVT1 ceRNA activity [2], betting on the hypothesis of a mechanism of titration, i.e. large variations in the ceRNAs expression levels can overcome, or relive, the repression of miRNA on its competitors, or similar over-expression of miRNA can abolish the competition between the two transcripts.

     On the other hand, a very promising example of co-expression network is the one implement by the software SWIM [3], which combines topological properties of correlation networks with gene expression data in order to identify a small pool of genes –called switch genes– critically associated with drastic changes in cell phenotype. SWIM has been successfully applied in viticulture [4], leading to the identification of key genes in the process of grapevine ripening, as well as in network medicine [3]. In particular, from a multi-cancer analysis SWIM identifies 100 common switch genes, which are implicated in cell cycle regulation, that could be negative regulators of cancer metabolism, and could in turn be controlled by growth factors such as E2F and NFY.
