Computational systems biology

Hiroaki Kitano
2002 Nature  
Molecular biology has uncovered a multitude of biological facts, such as genome sequences and protein properties, but this alone is not sufficient for interpreting biological systems.  ...  Neither p53 nor the network functions as a tumour suppressor in isolation. In this way, biological systems might be better characterized as symbiotic systems.  ...  For example, current control theory assumes that target values or statuses are provided initially for the systems designer, whereas in biology such targets are created and revised continuously by the system  ...

Multi-Level Complexities in Technological Development: Competing Strategies for Drug Discovery [chapter]

Matthias Adam
2010 Boston Studies in the Philosophy of Science  
Due to some fairly general properties of biological networks and the available options for pharmaceutical intervention, drug development is captured in an obstinate methodological dilemma.  ...  The analysis of these strategies reveals serious obstacles to integrating the study of interventive and systems complexity in a systematic, methodical way.  ...  In particular, the robustness and fragility of mechanistic networks is taken to be a feature of complex biological systems that is important for drug action.  ...
