Gene regulation describes the complex mechanism of inducing or repressing the expression of a gene. This highly dynamic process allows an organism to respond to a variety of environmental stimuli, as well as to control cell growth and differentiation during development. Gene regulation is orchestrated by a vast number of molecules, including transcription factors and cofactors, chromatin regulators, as well as other epigenetic mechanisms, and it has been shown that transcriptional misregulation, e.g., caused by mutations in regulatory sequences, is responsible for a plethora of diseases, including cancer, developmental or neurological disorders.
As a consequence, decoding the architecture of gene regulatory networks has become one of the most important tasks in modern (computational) biology. At the same time, next generation sequencing has been revolutionizing transcriptome analysis, providing large-scale quantification of gene expression at single-cell resolution, as well as the identification of novel genes and noncoding RNAs at unprecedented levels.
Thus, to advance our understanding of the mechanisms involved in the transcriptional apparatus, we need scalable approaches that can deal with the increasing number of large-scale, high-resolution, biological datasets. In particular, such approaches should be capable of efficiently integrating and exploiting the biological heterogeneity of these datasets—entailing different datatypes, experimental treatments, developmental stages, cell types, and even organisms—in order to best infer underlying regulatory networks, often in the absence of sufficient ground truth data for model training. With respect to scalability, randomized approaches have proven to be a promising alternative to deterministic methods in computational biology (and beyond). To give just a few examples, one of the top performers in benchmarks on gene regulatory network inference from gene expression data is based on random forest regression, and randomized dimensionality reduction techniques, such as randomized PCA, have been successfully employed to efficiently analyze genome-wide single-nucleotide polymorphism datasets.
This Special Issue aims at promoting randomized methods that will help to improve scalable gene regulatory network inference from a plethora of heterogeneous datasets. Papers are solicited on all areas directly related to these topics, including but not limited to:
- Randomized algorithms for scalable gene regulatory network inference;
- Module detection and clustering in gene regulatory networks;
- Cis-regulatory variant detection;
- (Large-scale) heterogeneous biological data integration;
- Randomized low-rank matrix approximation and dimensionality reduction;
- Feature extraction and latent factor identification;
- (Deep) randomized neural networks and reservoir computing;
- Sampling and Markov chain Monte Carlo methods.
