Systems biology

Methodology developed to understand how biological functions arise from multiple and complex interactions among many molecules and cells [1]. Network data are typically obtained with high-throughput data from whole-tissue [2], and single-cell omics [3], co-expression analysis [4], and protein-to-protein identification with two-hybrid assays [5]. Statistical tools include a plethora of mathematical analysis and computerized modeling, ranging from datadriven methods that aim to identify ‘patterns’, ‘clusters’, ‘correlations’, and ‘topology’, from experimental data [6] (e.g., principal component decomposition methods, supervised classification, linear/nonlinear regression methods, graph analysis, Bayesian networks, persistent homology), to modeldriven methods that aim, instead, to reconstruct networks that can be used in simulations (e.g., machine-learning classifiers, time series analysis, deterministic and stochastic differential equations) (reviewed in [7]).
