Incorporating time-delays in S-System model for reverse engineering genetic networks

Ahsan Chowdhury, Madhu Chetty, Nguyen Vinh
2013 BMC Bioinformatics  
Results: In this paper, we propose a novel Time-Delayed S-System (TDSS) model which uses a set of delay differential equations to represent the system dynamics.  ...  Moreover, we also propose a new criterion for model evaluation exploiting the sparse and scale-free nature of GRNs to effectively narrow down the search space, which not only reduces the computation time  ...  To infer a GRN of N genes using the S-System model, 2N(N+1) parameters must be estimated.  ...

2019 Biosystems (Amsterdam. Print)  
A gene regulatory network (GRN) represents a set of genes along with their regulatory interactions. Cellular behavior is driven by genetic level interactions.  ...  In this paper, we develop a complete framework for a novel model for GRN inference using MM kinetics. A set of coupled equations is first proposed for modeling GRNs.  ...  of real genetic networks.  ...
